We report a high seroprevalence of hepatitis E virus (HEV) in pigs in the Lao PDR. HEV seroprevalence was 51.2% (300/586) amongst abattoir pigs and 15.3% (46/301) amongst village pigs. The age distribution suggested previous in-village HEV pig infections. These findings suggest a zoonotic risk associated with village-based smallholder pig farming. 相似文献

Widespread use of antibiotics may be important in the spread of antimicrobial resistance. We estimated the proportion of Lao in- and outpatients who had taken antibiotics before medical consultation by detecting antibiotic activity in their urine added to lawns of Bacillus stearothermophilus, Escherichia coli, and Streptococcus pyogenes. In the retrospective (N = 2,058) and prospective studies (N = 1,153), 49.7% (95% confidence interval [CI] = 47.4-52.0) and 36.2% (95% CI = 33.4-38.9), respectively, of Vientiane patients had urinary antibiotic activity detected. The highest frequency of estimated antibiotic pre-treatment was found in patients recruited with suspected central nervous system infections and community-acquired septicemia (both 56.8%). In Vientiane, children had a higher frequency of estimated antibiotic pre-treatment than adults (60.0% versus 46.5%; P < 0.001). Antibiotic use based on patients histories was significantly less frequent than when estimated from urinary antibiotic activity (P < 0.0001). 相似文献

Under the supervision of the central and local health authorities, a pilot project was conducted in four villages in the Luangprabang Province, Lao PDR. The objective of the project was to test different regimes to supplement females with oral iron preparations to reduce iron deficient anemia (IDA) and control iodine deficiency disorders (IDD) in school children. Compared with iron sulphate tablets, iron fumerate tablets were well accepted and good compliance results were achieved. Hemoglobin concentration improved only in the group of females taking iron fumerate tablets. The goiter rate decreased from approximately 90% to about 45% for school children, regardless of whether iodine salt were used by their families or whether iodine capsules were used to treat the children. The latter attempt was hampered by the fact that also in the control village iodine fortified salt was used. This was due to a governmental attempt to control IDD nation-wide. Therefore, also in the control village a significant decrease in the goiter rate was observed. 相似文献
