Bird flu cases around the world are on the rise, and according to a Centers for Disease Control and Prevention (CDC) report, the numbers could be exponentially higher since many infections have asymptomatic symptoms. The study, which tested 150 veterinarians for the H5N1 antibodies, concluded that 3 of them were infected by the virus previously, but remained asymptomatic. This is raising concern among health officials, who fear that the infection could be spreading undetected.

Bird flu is a type of influenza virus that primarily affects birds but can sometimes infect humans and other animals. The most concerning strain, H5N1, spreads through infected birds' saliva, mucus, and feces. In rare cases, humans can become infected if they come into contact with these fluids, inhale contaminated air, or touch surfaces carrying the virus. While human infections remain rare, recent cases among poultry and dairy workers in the U.S. have raised concerns.
