According to Agence France-Presse reported on May 22, the U.S. health authorities announced on the 22nd that another case of human infection with avian influenza occurred in the United States. The case is related to the spread of the avian influenza virus among dairy cows.
The U.S. Centers for Disease Control and Prevention (CDC) said the infected person was working on a farm in Michigan where cows were infected with the H5N1 virus.
However, the CDC said that the current risk assessment of avian influenza to the American public is still low.
On April 1, the United States state of Texas announced a human case of avian influenza. The CDC said this is likely to be the world’s first case of avian influenza infection through cows.
The CDC noted that people infected in Michigan, like people infected in Texas, only develop symptoms in the eyes. Both have now recovered.
Reported that although human cases of infection with the disease are still rare, experts are concerned about the increasing number of mammals infected with the disease.
There is currently no evidence that the virus spreads from person to person, but scientists worry that the massive spread of the virus may cause the virus to mutate, allowing it to spread from person to person. (Compiled by Lin Xiaoxuan)
