Impact of the Coronavirus on Providing Oral Health Care in the Netherlands

ObjectiveTransmission of SARS-CoV-2 during oral health care is potentially increased compared to regular social activities. Specific amendments to the Dutch national infection control guidelines were promulgated. This study aimed to map the impact of the coronavirus pandemic on providing oral health care during the first wave of the coronavirus pandemic in 2020 in the Netherlands.MethodsA cross-sectional web-based survey was sent via email to a representative sample of dental hygienists and dentists in the Netherlands.ResultsOf the 1700 oral health care practitioners approached, 440 (25.9%) responded to the survey. Patient access to oral health care was severely restricted during the lockdown in the spring of 2020. A total of 1.6% of the oral health care practitioners had laboratory-confirmed COVID-19 during the study period, although this is likely to be an underrepresentation due to limited access to testing at that time. Over half of the participants perceived an increased risk of virus transmission during aerosol-generating treatments in their practices. A large majority (65.0%–87.1%) of the oral health care practitioners followed the COVID-19-specific amendments to the national infection control guidelines. Compared to the pre-pandemic period, additional personal protective equipment and protocols were applied. Factors related with compliance with the additional recommendations were age, employment status, and occupation.ConclusionsThe pandemic had a profound impact on both the accessibility and practice of oral health care. This survey study found that most Dutch oral health care practitioners paid extra attention to hygiene and infection control. Also, a low number of COVID-19 infections detected amongst Dutch oral health care practitioners was reported in the Netherlands. These overall outcomes suggest that safe oral health care can be provided when following the current infection control recommendations.Key words: SARS-CoV-2, COVID-19, Dental infection control, Dental care, Dental practice management, Dentists     

Effects of the COVID-19 pandemic on children’s oral health and oral health care use

BackgroundThe COVID-19 pandemic led to early restrictions on access to oral health care and social distancing requirements. The authors examined the early effects of the COVID-19 pandemic on children’s oral health and access to oral health care in the United States.MethodsUsing nationally representative data from the National Survey of Children’s Health, the authors compared several measures of children’s oral health and oral health care use early during the pandemic in 2020 with 1 year earlier. Logistic (multinomial or binary) regression models were estimated, adjusting for several child and household covariates and state fixed effects. Similar comparisons were estimated for 2019 relative to 2018 to evaluate prepandemic trends.ResultsChildren in 2020 were 16% (relative risk ratio, 0.84; 95% CI, 0.75 to 0.93) less likely to have excellent dental health as perceived by parents and 75% (relative risk ratio, 1.75; 95% CI, 1.14 to 2.67) more likely to have poor dental health than in 2019. In addition, children in 2020 had higher risk of bleeding gingivae (odds ratio, 1.46; 95% CI, 1.16 to 1.85). The likelihood of having a dental visit in the past 12 months was 27% (odds ratio, 0.73; 95% CI, 0.65 to 0.82) lower in 2020, including lower likelihood for preventive visits. The differences between 2020 and 2019 were observed across demographic and socioeconomic subgroups. There were no such differences between 2019 and 2018.ConclusionsThere was a widespread decline in children’s oral health status and access to oral health care early during the COVID-19 pandemic.Practical ImplicationsPrompt policies and oral health campaigns are needed to counter the pandemic effects and increase timely access to dental services.     

US dental health care workers’ mental health during the COVID-19 pandemic

BackgroundThis study was designed to assess the prevalence of anxiety and depression symptoms and understand factors influencing mental health among dental health care workers (DHCWs) during the COVID-19 pandemic.MethodsBeginning in June 2020, 8,902 DHCWs participated monthly in an anonymous longitudinal, web-based survey (response rate, 6.7%). The Patient Health Questionnaire-4 was used to estimate rates of anxiety and depression symptoms. Changes in mental health over time and differences by demographic and practice characteristics, COVID-19 community transmission level, and COVID-19 vaccination status were tested using χ² tests and multilevel multivariable logistic regression.ResultsAnxiety symptom rates peaked in November 2020 (28% of dental hygienists, 17% of dentists) and declined to 12% for both professions in May 2021. Depression symptom rates were highest in December 2020 (17% of dental hygienists, 10% of dentists) and declined to 8% in May 2021. Controlling for gender, age, race or ethnicity, and COVID-19 community transmission level, the authors found that dentists had significantly lower odds of anxiety symptoms (adjusted odds ratio [aOR], 0.82; 95% CI, 0.70 to 0.95) and depression symptoms (aOR, 0.79; 95% CI, 0.67 to 0.93) than dental hygienists. Compared with vaccinated respondents, those who were unvaccinated but planning on getting vaccinated had significantly higher rates of anxiety (aOR, 1.71; 95% CI, 1.20 to 2.44) and depression (aOR, 1.57; 95% CI, 1.07 to 2.29) symptoms.ConclusionsDHCWs’ mental health fluctuated during the pandemic. Anxiety and depression in DHCWs were associated with demographic and professional characteristics as well as perceived risk of COVID-19.Practical ImplicationsMental health support should be made available for DHCWs.This clinical trial was registered at ClinicalTrials.gov. The registration numbers are NCT04423770 and NCT04542915.     

Paediatric dental care during and post-COVID-19 era: Changes and challenges ahead

BackgroundCOVID-19 is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The virus is transmitted through respiratory droplets and by physical contact from contaminated surfaces to the mucosa. Its route of transmission has caused a significant challenge in medical and dental healthcare.ObjectiveThis article aims to review the literature and information available on the provision of paediatric dental treatment during and post-pandemic and to provide specific recommendations on the safe provision of paediatric dental care.ResultsChildren infected by SARS-CoV-2 have no or milder COVID-19 symptoms and are potential vectors in spreading the disease. Routine dental treatment is suspended in many countries because of the increased risk of cross-infection in dental practices. Only emergency dental care is provided for urgent conditions. It is necessary to gradually reinstate regular dental care to paediatric patients and maintain their good oral health. To control the disease transmission and maintain the oral health of the population, minimally intervention techniques that minimise or eliminate aerosol generation, plus comprehensive oral health preventive measures should be practised to safeguard safety at dental practices in this unprecedented time.ConclusionsRobust infection control guidelines should be implemented in dental clinics to minimise the risk of infection and to ensure the safety of patients and staff during the pandemic. Three levels of preventive care should be practised to prevent oral diseases and improve children's oral health in this COVID-19 era. Treatment should be prioritized to patients in urgent needs and aerosol-generating procedures should be minimized.     

Estimating COVID-19 prevalence and infection control practices among US dentists

BackgroundUnderstanding the risks associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission during oral health care delivery and assessing mitigation strategies for dental offices are critical to improving patient safety and access to oral health care.MethodsThe authors invited licensed US dentists practicing primarily in private practice or public health to participate in a web-based survey in June 2020. Dentists from every US state (n = 2,195) answered questions about COVID-19–associated symptoms, SARS-CoV-2 infection, mental and physical health conditions, and infection control procedures used in their primary dental practices.ResultsMost of the dentists (82.2%) were asymptomatic for 1 month before administration of the survey; 16.6% reported being tested for SARS-CoV-2; and 3.7%, 2.7%, and 0% tested positive via respiratory, blood, and salivary samples, respectively. Among those not tested, 0.3% received a probable COVID-19 diagnosis from a physician. In all, 20 of the 2,195 respondents had been infected with SARS-CoV-2; weighted according to age and location to approximate all US dentists, 0.9% (95% confidence interval, 0.5 to 1.5) had confirmed or probable COVID-19. Dentists reported symptoms of depression (8.6%) and anxiety (19.5%). Enhanced infection control procedures were implemented in 99.7% of dentists’ primary practices, most commonly disinfection, COVID-19 screening, social distancing, and wearing face masks. Most practicing dentists (72.8%) used personal protective equipment according to interim guidance from the Centers for Disease Control and Prevention.ConclusionsCOVID-19 prevalence and testing positivity rates were low among practicing US dentists. This indicates that the current infection control recommendations may be sufficient to prevent infection in dental settings.Practical ImplicationsDentists have enhanced their infection control practices in response to COVID-19 and may benefit from greater availability of personal protective equipment. ClinicalTrials.gov: NCT04423770.     

Willingness and ability of oral health care workers to work during the COVID-19 pandemic

BackgroundThe COVID-19 pandemic continues to disrupt dental practice in the United States. Oral health care workers play an integral role in societal health, yet little is known about their willingness and ability to work during a pandemic.MethodsOral health care workers completed a survey distributed on dental-specific Facebook groups during an 8-week period (May 1-June 30, 2020) about their willingness and ability to work during the COVID-19 pandemic, barriers to working, and willingness to receive a COVID-19 vaccine.ResultsFour hundred and fifty-nine surveys were returned. Only 53% of dentists, 33% of dental hygienists, 29% of dental assistants, and 48% of nonclinical staff members would be able to work a normal shift during the pandemic, and even fewer (50%, 18%, 17%, and 38%, respectively) would be willing to work a normal shift. Barriers included caring for family, a second job, and personal obligations, and these were faced by dental assistants and hygienists. Dentists were more likely than hygienists (P < .001), assistants (P < .001), and nonclinical staff members (P = .014) to receive a COVID-19 vaccine.ConclusionsOral health care workers have a decreased ability and willingness to report to work during a pandemic, and dentists are significantly more able and willing to work than hygienists and assistants. Dentists are more likely than staff to receive a COVID-19 vaccine.Practical ImplicationsThe results of this study may help inform future initiatives of dental workforce readiness during a pandemic. Dentists should be prepared to discuss alterations to standard operating procedures to allay staff members’ fears and improve retention rates during pandemics, allowing for improved access to oral health care.     

COVID-19 vaccine hesitancy and reasons for or against adherence among dentists

BackgroundCOVID-19 has spread widely among health care workers. Oral health care workers have an increased risk of being infected owing to dental practice characteristics. New, effective vaccines against COVID-19 have been approved for use. The authors aim was to evaluate intentions to be vaccinated against COVID-19 in a population of dentists and identify factors associated with their intentions.MethodsThe authors conducted an anonymous online survey among 761 dentists enrolled at the Board of Physicians and Dentists of the District of Monza Brianza, Monza, Italy. The authors collected data on demographic characteristics, influenza vaccine uptake, COVID-19 history, vaccine attitudes, and specific reasons for their intentions to be vaccinated against COVID-19 or not.ResultsOverall, 421 dentists completed the survey. More than 82% of the participants declared their intention to be vaccinated against COVID-19. The multivariate logistic regression model reported a positive association with receiving the influenza vaccine in the 2020-2021 influenza season (odds ratio, 5.15; 95% CI, 2.14 to 12.39) and a negative association with receiving a diagnosis of COVID-19 previously (odds ratio, 0.32; 95% CI, 0.15 to 0.66). The participants’ main reason for supporting vaccination was to protect their family and friends (87%) and their main reason for opposing vaccination was the lack of information (39%).ConclusionsIt is fundamental to consider vaccine hesitancy in health care workers and address it properly because they must provide recommendations to patients and promote adherence to vaccination programs.Practical ImplicationsThe vaccination of dental practitioners should be prioritized owing to the high risk related to dental practice.     

Soft Skills and Psychosocial Counselling in COVID-19 Times: the Changing Tactics

IntroductionAs the COVID-19 pandemic is increasingly griping the world, it starts effecting the psychosocial health of the patients, health care workers, frontline workers and their dependents. The entire landscape of existing patient psychological counselling and management needs to be changed to avoid fear and misinformation about COVID-19.Material and methodsIn this article, we have tried to summarize the rules, regulations and protocols in accordance with government guidelines along with practical implementation of counselling in management of psychological health condition of patients and frontline workers.ConclusionIf used wisely and as per recommendations, psychosocial counselling is a very useful tool in the present COVID-19 pandemic, to avoid spread of misinformation, fear and grief about the disease which creates mental health issue and anxiety among close contacts as well as health care workers.     

What is the association between income loss during the COVID-19 pandemic and children’s dental care?

BackgroundThe degree to which children experience unmet need for dental care during the COVID-19 pandemic and its association with pandemic-related household job or income loss are unknown.MethodsThe authors performed a cross-sectional household survey of 348 families in Pittsburgh, Pennsylvania, from June 25 through July 2, 2020. Unmet need for child dental care and pandemic-related household job or income loss were assessed using caregiver self-report.ResultsCaregivers reported that the greatest unmet child health care need during the COVID-19 pandemic was dental care (16%), followed by medical care for a well visit or vaccination (5%). Approximately 40% of caregivers reported job loss or a decrease in household income due to the COVID-19 pandemic. The authors found a significant association between the probability of unmet child dental care and pandemic-related household job or income loss (P = .022). Losing a job or experiencing a decrease in income due to the COVID-19 pandemic was associated with unmet child dental care (relative risk, 1.77; 95% confidence interval, 1.08 to 2.88).ConclusionsIn this sample, 3 times as many households reported unmet dental care for a child compared with unmet medical care. Unmet child dental care was more common in households where pandemic-related job or income loss occurred.Practical ImplicationsIf unmet dental care continues as a result of the COVID-19 pandemic, nontraditional strategies for delivering dental care can be considered to improve access to dental care for children, such as teledentistry and oral health prevention services in primary care settings.     

What is the rate of COVID-19 infection in a population seeking oral health care?

BackgroundAlthough rates of COVID-19 have remained low among US dentists, the authors aimed to determine the risk of there being COVID-19 in patients seeking oral health care.MethodsThe authors performed a retrospective chart review of all emergency department consultations from June 1, 2020, through December 31, 2020. They used Pearson correlation coefficients to compare rates with citywide prevalence (P < .05).ResultsThe authors located 203 encounters with 149 tests and 10 cases of COVID-19. Cases were strongly correlated with the citywide positivity rate (r = 0.9147; P = .0039). All patients who tested positive were asymptomatic and afebrile, and one-half (50%) visited a dentist within a week of consultation.ConclusionsThe rate of COVID-19 in a population seeking oral health care reflects the community positivity rate. Asymptomatic or presymptomatic patients pose risks to providers, staff members, and other patients.Practical ImplicationsDentists should remain vigilant during the ongoing COVID-19 pandemic, even with vaccination rollout. The Centers for Disease Control and Prevention maintains an accessible website with easy access to each state’s positivity rate and caseload.     

Dentistry and the COVID-19 Outbreak

IntroductionInfection prevention in dental practice is a principle of utmost importance aiming to protect patients, the dental team, and ultimately, public health. The recent pandemic of coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has instigated worldwide public concern. This highly contagious disease has called for profound changes in patient care around the world. The goal of this article is to review the current literature and introduce essential knowledge about COVID-19, recommend management protocols and adequate protection for dental professionals during the outbreak.Material and methodsThe literature search was conducted from April to June 2020. After full-text screening a total of 85 studies were included.ResultsGiven the novelty of SARS-CoV-2, some characteristics of the virus remain yet unknown. The virus is aerosol-transmissible and, because of the nature of dental procedures, this puts dental professionals and patients at a high risk of contamination by this pathogen. Adequate management protocols and specific protective approaches are essential to minimise the spread of COVID-19 in dental settings during the outbreak.DiscussionThe overall impact of COVID-19 in health care worldwide is yet to be determined. This constitutes a significant limitation to this review because the information obtained risks being outdated as the pandemic progresses. The prudent practitioner will use this review as a starting point and continue to proactively update themselves as the outbreak continues. Further studies are required to investigate the potential impact of infections with SARS-CoV-2 within dental settings.     

COVID-19–Related Factors Delaying Dental Visits of Workers in Japan

BackgroundThe aim of this research was to investigate the factors associated with postponing dental attendance amongst Japanese workers during the coronavirus disease 2019 (COVID-19) pandemic.MethodsWe conducted an internet-based survey in Japan from November 24 to 29, 2021. The participants were selected from people registered with an online research company. The inclusion criteria for this study were full-time or part-time workers aged 20 to 69 years. Participants filled out a questionnaire about their oral health, behaviour, and working conditions.ResultsA total of 1840 participants were included in the analysis. Three hundred ninety-eight participants (21.5%) answered that they postponed dental attendance due to COVID-19. Multiple logistic regression showed that women were more likely to postpone dental attendance (odds ratio [OR], 1.74; 95% confidence interval, 1.33–2.26). Moreover, employment status, household income, changes in income, working at home, interdental cleaning device use, regular dental attendance, awareness of untreated teeth, and dental pain were also associated with postponing dental attendance. The results of decision tree analysis showed that regular dental attenders with dental pain were the most likely to postpone dental attendance.ConclusionsThe characteristics of postponed dental visits for Japanese workers differ depending on whether one is a regular dental attender or not. Amongst regular dental attenders, worsening oral health due to interruptions in dental attendance is concerning. Meanwhile, untreated teeth might be neglected amongst nonregular dental attenders. Preventing patients from refraining from dental attendance, regardless of whether or not they are regular dental attenders, is important during the COVID-19 pandemic.

Multifaceted impact of COVID-19 on dental practice: American dental care professionals prepared and ready during unprecedented challenges

BackgroundThe purpose of this study was to evaluate the multifaceted impact of the COVID-19 pandemic on dental practices and their readiness to resume dental practice during arduous circumstances.MethodsThe authors distributed an observational survey study approved by The University of Texas Health Science Center at San Antonio Institutional Review Board to dental care practitioners and their office staff members using Qualtrics XM software. The survey was completed anonymously. The authors analyzed the data using R statistical computing software, χ² test, and Wilcoxon rank sum test.ResultsNearly all participants (98%) felt prepared to resume dental practice and were confident of the safety precautions (96%). Only 21% of dentists felt the COVID-19 pandemic changed their dental treatment protocols, with at least two-thirds agreeing that precautions would influence their efficiency adversely. Although most participants were satisfied with the resources their dental practice provided for support during the pandemic (95%), most were concerned about the impact on their general health and safety (77%) and to their dental practice (90%), found working during the pandemic difficult (≈ 60%), and agreed there are challenges and long-term impacts on the dental profession (> 75%).ConclusionsDental care professionals, although affected by the COVID-19 pandemic and at high risk of developing COVID-19, were prepared to resume dental practice during most challenging circumstances.Practical ImplicationsThe pandemic has affected dental care practitioners substantially; thus, there is need to formulate psychological interventions and safety precautions to mitigate its impact. Further research should evaluate the long-term effects on dentistry and oral health and interceptive measures for better communication and programming around future challenges.     

Association Between Toothbrushing Habits and COVID-19 Symptoms

ObjectivesThe association between toothbrushing and coronavirus disease 2019 (COVID-19) infections is unknown. The aim of this study was to test the hypothesis that the change in time and frequency of toothbrushing is associated with having COVID-19 symptoms.MethodsIn this 8-month retrospective cohort study, we used the data from the Japan COVID-19 and Society Internet Survey (JACSIS; N = 22,366), which was conducted between August and September 2020. The logistic regression analyses were used to calculate the odds ratios (ORs) of having the 3 main COVID-19 symptoms (high fever, cough, and taste and smell disorder). Confounders were age, sex, educational attainment, equivalised income level, self-rated health, health literacy, and living area.ResultsThe mean age of the participants was 49 years (SD = ±17.3), and 49.2% were male. Overall 2704 (12.1%) participants changed (increased or decreased) the time and frequency of toothbrushing, whilst 19,662 (87.9%) did not change. Only 60 participants (0.3%) had the 3 main COVID-19 symptoms. All logistic regression models showed that those who had a change in time and frequency of toothbrushing had higher odds of having the 3 main COVID-19 symptoms compared to those who had unchanged time and frequency of toothbrushing. The ORs ranged from 6.00 (95% confidence interval [CI], 3.60–9.99) in the crude model to 4.08 (95% CI, 2.38–6.98) in the fully adjusted model.ConclusionsThe change in time and frequency of toothbrushing from before to after the COVID-19 pandemic was associated with having the 3 main COVID-19 symptoms.     

Caregiver acceptance of an anticipated COVID-19 vaccination

BackgroundThe world is hopeful a vaccine will help mitigate the COVID-19 pandemic. The authors conducted a hospital-based study using a questionnaire to examine parental acceptance of an anticipated COVID-19 vaccination.MethodsA 41-item questionnaire using the Health Belief Model was administered to caregivers of children receiving oral health care in a dental clinic in an urban pediatric teaching hospital. Demographic, health-seeking, and health-behavior questions were assessed.ResultsA total of 39.2% of caregivers would not allow their child to receive a COVID-19 vaccination. Whereas 27.8% of caregivers agreed that if their physician recommends a COVID-19 vaccination, they will allow their child to receive it, 52.2% said that a health care professional could influence this decision.ConclusionsDentists, intimately aware of the suggested risks of aerosol-generating procedures, can play a critical role in educating the public about the importance of accepting a COVID-19 vaccine.Practical ImplicationsDentists are in a unique position to discuss and advocate for vaccine acceptance. If a COVID-19 vaccine is not widely accepted, risks associated with performing aerosol-generating procedures will remain.     

The “oral” history of COVID-19: Primary infection,salivary transmission,and post-acute implications

Severe acute respiratorysyndrome coronavirus 2 (SARS-CoV-2), the causative agent of COVID-19, has led to more than 3.25 million recorded deaths worldwide as of May 2021. COVID-19 is known to be clinically heterogeneous, and whether the reported oral signs and symptoms in COVID-19 are related to the direct infection of oral tissues has remained unknown. Here, we review and summarize the evidence for the primary infection of the glands, oral mucosae, and saliva by SARS-CoV-2. Not only were the entry factors for SARS-CoV-2 found in all oral tissues, but these were also sites of SARS-CoV-2 infection and replication. Furthermore, saliva from asymptomatic individuals contained free virus and SARS-CoV-2-infected oral epithelial cells, both of which were found to transmit the virus. Collectively, these studies support an active role of the oral cavity in the spread and transmission of SARS-CoV-2 infection. In addition to maintaining the appropriate use of personal protective equipment and regimens to limit microbial spread via aerosol or droplet generation, the dental community will also be involved in co-managing COVID-19 “long haulers”—now termed Post-Acute COVID-19 Syndrome. Consequently, we propose that, as SARS-CoV-2 continues to spread and as new clinical challenges related to COVID-19 are documented, oral symptoms should be included in diagnostic and prognostic classifications as well as plans for multidisciplinary care.     

Frequency and pattern of outpatient dental visits during the COVID-19 pandemic at hospital and community clinics

BackgroundThe authors aimed to measure the frequency of dental visits before and during the COVID-19 pandemic and to evaluate whether dental visits can be predicted from demographic characteristics, socioeconomic status, oral problem diagnoses, and dental service providers.MethodsParticipants for this retrospective study were patients visiting dental care providers at hospital- and community-based outpatient clinics in Alberta, Canada. Data were retrieved from electronic databases from March 12, 2020, through September 30, 2020, and from the same period for 2018 and 2019. The COVID-19 lockdown was declared for March 12 through May 14, 2020. Data were analyzed using analysis of variance test and multiple logistic regression at α = 0.05.ResultsFrom a total of 14,319 dental visits, 5,671, 5,036, and 3,612 visits occurred in 2018, 2019, and 2020, respectively. The mean (standard deviation) frequency of daily visits was 36.69 (15.64), 32.09 (15.51), and 24.24 (14.78), respectively. Despite the overall decrease, the frequency of visits for infections, salivary problems, and temporomandibular disorders increased during the COVID-19 pandemic in 2020. Dental visits during the pandemic were associated with more complicated oral diagnoses and dental services as well as higher economic status.ConclusionsDuring the COVID-19 pandemic, the frequency of dental visits decreased specifically during lockdown. Patients with complicated problems requiring urgent treatments mainly visited dental clinics. Reduced access to care was observed primarily among socially disadvantaged groups.Practical ImplicationsAlthough guidelines and related recommendations have been effective in restoring the compromised dental system during the COVID-19 pandemic, additional modifications are needed to promote in-person visits to improve the oral health status of patients.     

COVID-2019 fundamentals

BackgroundA novel coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was identified at the end of 2019. The disease caused by SARS-CoV-2 was named COVID-19. The main purpose of this review was to provide an overview of SARS-CoV-2.MethodsThe authors searched the MEDLINE database for clinical studies related to virus characteristics, pathogenesis, diagnosis, transmission mechanisms, and treatment options.ResultsAs of January 27, 2021, the number of infected people and deaths associated with COVID-19 worldwide were approximately 100 million and 2 million, respectively. The manifestations of COVID-19 are variable, and the severity is affected by age and preexisting medical conditions. Children and adolescents are usually asymptomatic or have mild symptoms. Older adults, in comparison, may experience severe illness and have disproportionally elevated mortality. Among those who survive, some may experience enduring deficits. The viral load is particularly elevated in saliva and oropharynx, which constitute potential sources of infection. The diagnosis of the disease may be confounded by factors related to the replicating cycle of the virus, viral load, and sensitivity of the diagnostic method used. As of January 2021, COVID-19 has no cure but can be prevented. Its treatment is based on supportive care along with antiviral medications and monoclonal antibodies. In severe cases with multiorgan involvement, mechanical ventilation, dialysis, and hemodynamic support may be necessary.ConclusionsCOVID-19 is a transmittable disease with a variable course. A substantial number of patients, particularly children, remain asymptomatic. Important advances have been made in the development of new treatments. However, the mortality in vulnerable populations remains elevated.Practical ImplicationsThe elevated viral load in the oral cavity and pharynx suggests that oral health care professionals could get infected through occupational exposure. Providers should understand the variables that influence the yield of diagnostic studies because false-negative results can occur.
