On July 21, an 11-year-old boy died of H5N1 avian influenza in Delhi. This is the first recorded death due to the bird flu in India this year. In January, bird flu was confirmed in several states with thousands of birds, including migratory species, being found dead.

What is bird flu?

Bird flu or avian influenza is a disease caused by avian influenza Type A viruses found naturally in wild birds worldwide.
The virus can infect domestic poultry including chickens, ducks, turkeys and there have been reports of H5N1 infection among pigs, cats, and even tigers in Thailand zoos.
Avian Influenza type A viruses are classified based on two proteins on their surfaces – Hemagglutinin(HA) and Neuraminidase(NA).
There are about 18 HA subtypes and 11 NA subtypes. Several combinations of these two proteins are possible e.g., H5N1, H7N2, H9N6, H17N10, etc.

Bird flu: Infection in humans

The most common route of virus transmission is direct contact — when a person comes in close contact with infected birds, either dead or alive.
Humans can also be affected if they come in contact with contaminated surfaces or air near the infected poultry.
There is no sufficient evidence suggesting the spread of the virus through properly cooked meat.

Symptoms of avian influenza:

According to US CDC, the reported signs and symptoms of avian influenza A virus infections in humans have ranged from mild to severe influenza-like illness.
Fever, cough, sore throat, muscle aches, nausea, abdominal pain, diarrhea, vomiting
Severe respiratory illness (e.g., shortness of breath, difficulty breathing, pneumonia, acute respiratory distress, viral pneumonia, respiratory failure).
