The CDC told Newsweek Monday that while bird flu's current risk to the general public remains low, the agency is carefully monitoring for several red flags that could indicate that the virus could be on the verge of becoming a pandemic.

Those red flags include any outbreaks of bird flu that are spread from person-to-person, as well as evidence that the virus has mutated, making it easier for it to spread between humans.
