Abstract
BACKGROUND
The frequency of avian influenza A virus infections among poultry workers is not well understood.
METHODS
A seroprevalence study of market poultry workers and persons without occupational poultry exposure was conducted during 2001 in Hanoi, Vietnam. Sera were tested for avian influenza H5 and H9 antibodies by microneutralization and Western blot assays.
RESULTS
Seroprevalence of H5 and H9 antibodies was 4% and 3% in poultry workers and 1% and 3.5% in non-poultry workers, respectively.
CONCLUSIONS
Seroprevalence of H5 and H9 antibodies was low among Hanoi market poultry workers in 2001, but can serve as a baseline for additional studies.
摘要
背景
家禽工人中感染甲型禽流感病毒的频率尚不清楚。
方法
2001 年在越南河内对市场家禽工人和无职业性家禽接触者进行了血清流行率研究。通过微量中和试验和 Western blot 试验检测血清中的禽流感 H5 和 H9 抗体。
结果
家禽工人中 H5 和 H9 抗体的血清阳性率分别为 4%和 3%，非家禽工人中分别为 1%和 3.5%。
结论
2001 年，河内市场家禽工人中 H5 和 H9 抗体的血清阳性率较低，但可作为进一步研究的基线。
