Boy diagnosed with bird flu in Hong Kong

Hong Kong health authorities were on high alert on Monday after a toddler was diagnosed with bird flu over the weekend, representing the area's first human case of the disease in more than a year.

The boy is isolated and is receiving treatment at Hong Kong's Princess Margaret Hospital. He was in the hospital several days prior to the H5N1 avian influenza diagnosis for obstructive hydrocephalus, also known as water on the brain. The two-year-old remained in serious condition on Monday, BNO News reports.

"The boy's parents are all along asymptomatic, which means the chance of a human-to-human transmission is slim," a spokesman for the Center for Health Protection of the Hong Kong Department of Health said, according to BNO News.

The genes characterized in the virus belong to the same clade found in wild birds, indicating that it was likely that the boy was infected by a bird and not a human. The toddler visited a market with live poultry in Guangzhou in mid-May, though he had no direct contact with poultry. After spending two days in Anhui province, the boy traveled to Hong Kong and fell ill.

The parents, five people who reported respiratory issues and two healthcare workers tested negative for the disease. Cambodia, Indonesia, Vietnam and China have all reported deaths from bird flu this year.
