ABSTRACT
Epidemic of influenza A H5 N1 virus in humans occurred in South Vietnam from 12/2003 up to now there were 287 suspected cases and 24 confirmed cases, included 20 deaths with case-fatality rate was very high (83.33%). Based on epidemical surveillance and laboratory, we believed that cases usually appear by the end of year and the beginning of the next year at the same time of the winter in North Vietnam, and the dry season in the South Vietnam. It was distributed sporadically in different regions, including highland, urban areas and rural areas of the Mekong delta. Almost of the confirmed cases were young (average 16,17 years old). The rate of ethnic patients with H5N1(+) were high 25%. There has been no evidence of human to human transmission, but there were some risk factors associated with the confirmed cases were contact directly with the sick/dead poultry (OR=3.39; p=0.034), eating the sick/dead poultry (OR=4.28; p= 0.025), person in family prepared chicken that was sick and died for cooking (OR=5.2; p=0.01).
