Why in news
Researchers at Ashoka University used the BharatSim model to simulate H5N1 bird flu transmission to humans, highlighting the necessity of early intervention and specific culling strategies.
Background
Researchers Philip Cherian and Gautam Menon utilized a computer simulation model named BharatSim to study H5N1 outbreaks. The study found that isolating infected individuals and quarantining households can contain the virus at the secondary stage.
