Bird Flu H5N1 Could Spark Next Pandemic
Scientists are watching bird flu, especially the H5N1 strain, because it could start spreading easily among people.
Right now, it doesn't infect humans easily, but a single mutation could change that.
If it starts spreading, it could cause a big outbreak because most people don't have immunity against it.
Researchers in India created a computer model to see how a bird flu outbreak might happen and how to stop it.
They found that quarantining households early could help contain the spread.
The model was based on a village in Tamil Nadu, India, and showed how the virus could spread through farms, markets, schools, and workplaces.
H5N1 bird flu strain could start spreading easily among humans with a single mutation.
From 2003 to August 2025, 990 human H5N1 cases were reported, with 475 deaths.
Symptoms in humans include high fever, cough, sore throat, muscle aches, and conjunctivitis.
Researchers in India created a computer simulation to model a bird flu outbreak and containment strategies.
Quarantining households of primary contacts when just two cases are detected could contain the outbreak.
