An 11-year-old boy from Gurgaon died of H5N1 avian influenza or bird flu Tuesday while being treated at the AIIMS, Delhi.
An AIIMS official stated that the boy had been admitted to the hospital on July 2, adding that he died Tuesday. The official said that AIIMS staffers who came in contact with the patient are all under isolation.
The State Surveillance Unit of the Integrated Disease Surveillance Project (IDSP) under the Union Ministry of Health too has initiated an epidemiological probe and put close contacts of the patient under surveillance to watch out for symptoms.
On July 21, a total of 5,750 persons were surveyed in Gurgaon, while 25 poultry farms were surveyed by the health workers and Haryana’s department of animal husbandry.
“There is no suspected case of bird flu found in the area. All the health workers are directed to enhance surveillance in the area of 10 km,” a report sent by District Surveillance Officer, Gurgaon to State Surveillance Unit mentioned.
In the initial report sent by District Surveillance Officer (IDSP), Gurgaon, to State Surveillance Unit, Panchkula, on July 18 about the infected child, it was mentioned that “as per the history given by the mother, child had no direct contact with any poultry animals….At present, his brother, his parents and grandparents are doing well and have no symptoms of the said disease.

Avian influenza is a highly contagious viral disease caused by Influenza Type A viruses which generally affects poultry such as chickens and turkeys. It does not spread easily to humans.
People who have come in close contact with infected birds, dead or alive, can contract the H5N1 virus, but according to the WHO, it does not usually spread from person to person. However, it can be deadly when it does infect humans, with a mortality rate of almost 60 per cent.
The WHO has also pointed out that there is no evidence of the virus spreading through properly prepared and cooked poultry as the virus is sensitive to heat and dies in cooking temperatures. Earlier this year, in January, the deaths of a large numbers of birds in various parts of the country had raised bird flu alarm and the virus was detected in birds in Himachal Pradesh, Rajasthan, Madhya Pradesh, Kerala, Haryana and Maharashtra.
Samples from Rajasthan, Madhya Pradesh, Haryana and Kerala had tested positive for the A (H5N8) strain of the virus, while samples from Himachal Pradesh had tested positive for A (H5N1).
