Summary
Indian scientists have simulated how bird flu, known as H5N1, might spread from birds to humans and potentially cause a global health crisis. The researchers, using computer models, have shown that early intervention could stop an outbreak from spreading widely. Bird flu has occasionally infected humans, but the risk of a pandemic increases with human-to-human transmission.
Key Facts
- Bird flu, or H5N1, is a type of influenza virus that can spread from birds to humans.
- The World Health Organization has reported 990 human cases globally, with a high fatality rate of 48% since 2003.
- In the US, the virus has affected more than 180 million birds and resulted in 70 human infections.
- Indian researchers used simulations to explore possible spread scenarios and prevention measures.
- A study suggests quick quarantine measures could contain an outbreak if detected early.
- The research model focused on a single village in India's key poultry-producing area to understand local outbreak dynamics.
- The threat of a pandemic grows if the virus begins to spread between people, not just from birds to humans.
