The World Health Organization (WHO) has confirmed a second human case of H9N2 avian influenza in West Bengal, India, raising concerns about the potential for wider spread. The first case was reported earlier this year in the same state. While H9N2 is typically found in poultry, its transmission to humans is rare and usually results in mild or asymptomatic infections.

What is H9N2?

H9N2 is a type of avian influenza virus commonly found in poultry. It can cause respiratory illness in birds, but rarely spreads to humans. When it does, infections are usually mild, with symptoms like fever, cough, and sore throat.

How is it transmitted?

The virus primarily spreads through direct contact with infected poultry or contaminated environments. Human-to-human transmission is extremely rare.

Symptoms in humans:

Most people infected with H9N2 experience mild symptoms, including:

Fever
Cough
Sore throat
Runny nose

In rare cases, more severe illness can occur.

WHO’s Role:

The WHO is monitoring the situation closely and providing guidance to countries on preventing further spread. They emphasize the importance of:

Maintaining proper hygiene and sanitation in poultry farms.
Preventing contact with sick poultry.
Seeking medical attention if experiencing flu-like symptoms after exposure to poultry.

Precautionary Measures:

To minimize the risk of infection:

Avoid contact with sick or dead poultry.
Wash hands thoroughly after handling poultry.
Cook poultry thoroughly to kill the virus.
Avoid contact with poultry droppings.

What’s next?

The WHO is working closely with the Indian authorities to investigate the source of the infection and prevent further spread. The current situation emphasizes the need for continuous surveillance and preventive measures to protect public health.
