Cambodia has reported its fourth human H5N1 avian flu case of the year, the brother of a 9-year-old boy who recently died from his H5N1 infection, according to a statement from the country's health ministry that was translated and posted by Avian Flu Diary, an infectious disease news blog.
The latest confirmed case is a 16-year-old boy who didn't have respiratory symptoms. The boy and his deceased younger brother are from Kratie province in northeastern Cambodia. The health ministry didn't say if the teen had any other symptoms, but it said it continues to track contacts and has distributed oseltamivir to close contacts of confirmed cases.
Earlier report noted poultry deaths
The current statement didn't have any details about the teen's exposure. The ministry statement last week announcing his brother's illness and death said poultry had died at the patient's home and that dead birds were eaten.
Cambodia has now reported 10 human H5N1 cases since 2023, part of rise in cases that follows a decade-long lapse in cases. The country's recent cases have involved an older H5N1 clade (220.127.116.11c) that is known to circulate in the country's poultry. It is different than the newer H5N1 clade (18.104.22.168b) that is circulating widely in wild birds and poultry in multiple world regions, with sporadic detections in mammals and humans.
