H7N9

H7N9 is a type of bird flu caused by a virus that mainly affects birds but can infect humans. It was first identified in China in 2013. Humans typically become infected through close contact with infected live poultry or contaminated environments. Symptoms can range from mild fever and cough to severe pneumonia and respiratory failure. While human-to-human transmission is limited, the virus poses a significant health risk due to its potential to cause serious illness. Preventive measures include avoiding contact with live poultry and practicing good hygiene. Ongoing monitoring and vaccination efforts are vital to controlling its spread.
