What you need to know about the Human Metapneumovirus (HMPV)

Causes

Human Metapneumovirus HMPV is a respiratory virus that belongs to the Pneumoviridae family. It was first identified in 2001 by Dutch scientists. The virus spreads through respiratory droplets when an infected person coughs, sneezes, or talks. It can also spread by touching contaminated surfaces and then touching the face.

Effects

HMPV typically causes mild cold-like symptoms, such as:

• Cough
• Fever
• Nasal congestion
• Sore throat
• Fatigue

In severe cases, it can lead to more serious respiratory illnesses like pneumonia or bronchopneumonia, especially in vulnerable populations such as young children, the serior citizens, and individuals with weakened immune systems.

Precautions

To prevent the spread of HMPV, it is important to:

• Practice good hygiene, such as frequent handwashing with soap and water.
• Avoid close contact with infected individuals.
• Cover your mouth and nose with a tissue or your elbow when coughing or sneezing.
• Disinfect frequently-touched surfaces regularly.
• Stay home when you are sick to avoid spreading the virus to others.

Treatment

Currently, there is no specific antiviral treatment or vaccine for HMPV. Treatment mainly focuses on supportive care, such as:

• Rest and hydration
• Over-the-counter medications to relieve symptoms like fever and congestion
• In severe cases, hospitalization may be required for supportive care and monitoring

Situation in India

HMPV has been circulating in India for several years. Studies have shown that the virus is present in the population, with varying prevalence rates. For example, a 2024 study by the Indian Council of Medical Research (ICMR) found that 4% of pediatric patients tested positive for HMPV. The virus tends to peak during the winter months, and cases have been reported across different regions of the country.

In recent times, there has been a rise in HMPV cases, prompting health authorities to monitor the situation closely. While most cases are mild, it is important for high-risk groups to take extra precautions.

Situation in Bangalore

Recently, two cases of Human Metapneumovirus (HMPV) were detected in Bangalore. Both cases involved infants admitted to Baptist Hospital. The first case was a three-month-old female infant with a history of bronchopneumonia, who has since been discharged. The second case is an eight-month-old male infant who tested positive for HMPV on January 3rd and is currently recovering.

Health authorities have emphasized that there is no cause for alarm. The Indian Council of Medical Research (ICMR) and the Integrated Disease Surveillance Programme (IDSP) are closely monitoring the situation. The cases were detected through routine surveillance, and there has been no unusual surge in respiratory illnesses in the city.

Karnataka Health Minister Dinesh Gundu Rao has assured the public that the state government is well-prepared to handle any potential increase in respiratory illnesses. He also clarified that the detected cases are not linked to the new variant reported in China.

The government has issued guidelines to prevent the spread of infections, including covering the mouth and nose while coughing or sneezing, frequent handwashing, and avoiding crowded places. There is currently no need for a mask mandate or prohibition of public movement.
