Can bird flu infect humans without spreading between people?
Yes, bird flu can infect humans through direct contact with infected birds or contaminated environments. However, so far, there is no evidence of sustained human-to-human transmission, which means the virus hasn't yet adapted to spread easily between people.
-
What does resistance to the fever response mean for bird flu outbreaks?
Recent research shows that bird flu may resist the body's natural fever response, allowing it to thrive at higher temperatures typical of birds. This resistance could make the virus more severe in humans and complicate efforts to contain outbreaks.

Is bird flu becoming more dangerous for humans?
While bird flu remains primarily a concern for poultry and wild birds, its ability to infect humans and resist fever responses raises concerns about potential increased danger. Scientists are closely watching for signs of the virus adapting to transmit more easily between humans.
-
What should I do to stay safe from bird flu?
To stay safe, avoid contact with wild birds and sick poultry, practice good hygiene, and stay informed about local outbreaks. If you develop flu-like symptoms after exposure, seek medical advice promptly.

Could bird flu cause a pandemic in the future?
There is a concern that if bird flu adapts to transmit easily between humans, it could cause a pandemic. Experts emphasize the importance of monitoring gene swaps and virus mutations to prevent such a scenario.
