“The matter was also reported to the Animal Husbandry Department of Haryana,” the government said.

Based on the available information, the team of doctors and nurses treating the patient are being monitored since July 16 for development of any influenza-like illness with no one reported symptomatic till date, said the health ministry.

Family members, close contacts and health care workers are still under surveillance and none have shown any symptoms yet, said a government statement.

Contact tracing, an active search for any symptomatic case has been carried out in the hospital and area where the case resided, said the ministry.

The Animal Husbandry Department has also not found any suspected cases of bird flu in the area and has enhanced surveillance in a 10 km zone as a precautionary measure.

All about bird flu

Avian influenza is caused by infection with avian (bird) influenza (flu) Type A viruses. These viruses occur naturally among wild aquatic birds worldwide and can infect domestic poultry and other bird and animal species. Avian flu viruses do not normally infect humans. However, sporadic human infections with avian flu viruses (types H5, H7 H9) have occurred.

How humans are infected

Infected birds shed avian influenza virus in their saliva, mucous and faeces. Human infections with bird flu viruses can happen when enough virus gets into a person’s eyes, nose or mouth, or is inhaled. This can happen when a virus is in the air (in droplets or possibly dust) and a person breathes it in, or when a person touches something that has virus on it then touches their mouth, eyes or nose.

Signs

Conjunctivitis, influenza-like illness, sometimes accompanied by nausea, abdominal pain, diarrhoea, shortness of breath, pneumonia, acute respiratory distress, viral pneumonia, altered mental status

Prevention

Avoid sources of exposure. Most human infections with avian influenza A viruses have occurred following direct or close contact with infected poultry.
