Free-roaming camels, especially those crossing national borders, pose a high risk for spreading Middle East respiratory syndrome coronavirus (MERS-CoV). To prevent outbreaks, active surveillance is necessary. We found that a high percentage of dromedaries in Tunisia are MERS-CoV seropositive (80.4%) or actively infected (19.8%), indicating extensive MERS-CoV circulation in Northern Africa. 相似文献

高致病性冠状病毒具有高发病率、高病死率以及全球大流行等特点,严重威胁人类健康,给社会经济带来巨大挑战。目前关于高致病冠状病毒的致病机制,主要从直接细胞病变效应和间接免疫病理损伤两方面进行讨论,但具体作用基因的研究尚需进一步深入。本文从高致病性冠状病毒的基因结构特点与致病机制的相关性进行综述,为预防和治疗高致病性冠状病毒感染提供参考。 相似文献

The ongoing global pandemic caused by coronavirus disease has once again demonstrated the role of the family Coronaviridae in causing human disease outbreaks. Because severe acute respiratory syndrome coronavirus 2 was first detected in December 2019, information on its tropism, host range, and clinical manifestations in animals is limited. Given the limited information, data from other coronaviruses might be useful for informing scientific inquiry, risk assessment, and decision-making. We reviewed endemic and emerging infections of alphacoronaviruses and betacoronaviruses in wildlife, livestock, and companion animals and provide information on the receptor use, known hosts, and clinical signs associated with each host for 15 coronaviruses detected in humans and animals. This information can be used to guide implementation of a One Health approach that involves human health, animal health, environmental, and other relevant partners in developing strategies for preparedness, response, and control to current and future coronavirus disease threats. 相似文献

目前全球范围内正流行新型冠状病毒肺炎(COVID-19),而其强烈的传播性已引发重大公共卫生危机。新型冠状病毒与严重急性呼吸综合征(SARS)冠状病毒、中东呼吸综合征(MERS)冠状病毒存在高度病原同源性,同为β属冠状病毒。由于孕妇群体在生理和心理上存在一定脆弱性,为疫情流行期间的易感人群和高危人群,本文将对目前所报道的孕产妇罹患SARS、MERS、COVID-19对母婴健康影响进行文献综述,旨在为COVID-19流行中孕妇健康管理与防控提供依据。 相似文献

Middle East respiratory syndrome (MERS) cases continue to be reported from the Middle East. Evaluation and testing of patients under investigation (PUIs) for MERS are recommended. In 2013–2014, two imported cases were detected among 490 US PUIs. Continued awareness is needed for early case detection and implementation of infection control measures. 相似文献

We investigated an outbreak of Middle East respiratory syndrome (MERS) at King
Fahad Medical City (KFMC), Riyadh, Saudi Arabia, during March 29–May 21,
2014. This outbreak involved 45 patients: 8 infected outside KFMC, 13 long-term
patients at KFMC, 23 health care workers, and 1 who had an indeterminate source
of infection. Sequences of full-length MERS coronavirus (MERS-CoV) from 10
patients and a partial sequence of MERS-CoV from another patient, when compared
with other MERS-CoV sequences, demonstrated that this outbreak was part of a
larger outbreak that affected multiple health care facilities in Riyadh and
possibly arose from a single zoonotic transmission event that occurred in
December 2013 (95% highest posterior density interval November 8,
2013–February 10, 2014). This finding suggested continued health
care–associated transmission for 5 months. Molecular epidemiology
documented multiple external introductions in a seemingly contiguous outbreak
and helped support or refute transmission pathways suspected through
epidemiologic investigation. 相似文献

We investigated the kinetics of serologic responses to Middle East respiratory syndrome coronavirus (MERS-CoV) infection by using virus neutralization and MERS-CoV S1 IgG ELISA tests. In most patients, robust antibody responses developed by the third week of illness. Delayed antibody responses with the neutralization test were associated with more severe disease. 相似文献

In 2013, a novel betacoronavirus was identified in fecal samples from dromedaries in Dubai, United Arab Emirates. Antibodies against the recombinant nucleocapsid protein of the virus, which we named dromedary camel coronavirus (DcCoV) UAE-HKU23, were detected in 52% of 59 dromedary serum samples tested. In an analysis of 3 complete DcCoV UAE-HKU23 genomes, we identified the virus as a betacoronavirus in lineage A1. The DcCoV UAE-HKU23 genome has G+C contents; a general preference for G/C in the third position of codons; a cleavage site for spike protein; and a membrane protein of similar length to that of other betacoronavirus A1 members, to which DcCoV UAE-HKU23 is phylogenetically closely related. Along with this coronavirus, viruses of at least 8 other families have been found to infect camels. Because camels have a close association with humans, continuous surveillance should be conducted to understand the potential for virus emergence in camels and for virus transmission to humans. 相似文献
