On December 31, local time, according to the latest data from the U.S. Centers for Disease Control and Prevention (CDC),66 people in the United States have been confirmed to be infected with the avian influenza virus. The CDC is paying close attention to red flags related to avian influenza and whether the disease could develop into a pandemic. Red flags include outbreaks of human-to-human transmission and viral mutations.


According to reports, the CDC announced last week that a patient hospitalized with severe avian influenza in Louisiana was found to be infected with a mutated virus, and the case was a red flag case. The Louisiana patient has not been found to have spread the virus to anyone else. (Headquarters reporter Zhang Yingzhe)
