Key Facts About Bird Flu  

• About: Bird flu (avian influenza) is a highly contagious viral disease caused by avian influenza A viruses, particularly subtypes H5N1 and H5N8, affecting both wild and domestic birds. 
• History of Human Cases: First human cases were reported in 1997 (Hong Kong). Most have occurred in Asia and were linked to close contact with infected birds.  
• Transmission: H5N1 spreads primarily through direct contact with infected live or dead birds or contaminated environments (e.g., live bird markets).  
  • Human infections of H5N1 are rare, with a high fatality rate (~60%), much higher than Covid-19 (~3%).  
  • Transmission from mammals to humans has been observed, but airborne and sustained human-to-human transmission are not confirmed.  
    • H5N1 is listed as a priority disease under WHO R&D Blueprint.  
• Symptoms: Common symptoms include high fever, cough, sore throat, and muscle aches.  
  • Severe cases can lead to respiratory failure or neurological complications. Some individuals may remain asymptomatic despite exposure.  
• Treatment: Current seasonal flu vaccines do not protect against H5N1.   
  • Antiviral drugs like oseltamivir are effective, especially when administered early in high-risk or severe cases.
