Bird flu i.e. avian influenza is a dangerous disease, which usually occurs in birds. But now this virus is also infecting humans and animals, due to which its danger has increased again across the world. 20 cats have died due to bird flu in America. These deaths have occurred due to transmission of the virus from birds to animals. Recently, a person in America also got infected with this virus.
After examining the blood sample of this person, it was found that mutation was taking place in the virus. This means that the bird flu virus may now be more dangerous than before. The US Centers for Disease Control and Prevention (CDC) said that the first serious case of bird flu was investigated in America last week. In this investigation, such mutations of the virus were found, which were not seen in any infected person before.
When a virus changes to make itself stronger, it is called mutation. According to CDC, this mutation of bird flu was found especially in the hemagglutinin (HA) gene, which is a dangerous part of the virus. This virus strain is rare, but such mutations have been seen in some serious cases before. This type of mutation was also seen in a serious case in British Columbia, Canada.
The first serious case of bird flu was reported in America last week. In Louisiana, a man over 65 years of age was having trouble breathing, after which he was admitted to the hospital. After investigation, it was found that he was infected with bird flu, which can spread through birds or animals.
