he Centers for Disease Control and Prevention (CDC) revealed it is monitoring for a number of red flags that suggest bird flu could become the world’s next pandemic.
The first severe human bird flu case in the United States was reported in Louisiana earlier this month.
Genetic analysis found the virus had mutated, making it more easily transmissible to humans, the CDC said.
The agency called the mutations “concerning’ and “a reminder that A(H5N1) viruses can develop changes during the clinical course of a human infection.”
