HMPV Virus Cases Reported in India: Everything You Need to Know About This COVID-Like Infection

New Delhi, January 7 – Five years after the COVID-19 pandemic emerged, China is once again in the spotlight with the detection of a new respiratory illness caused by the HMPV virus (Human Metapneumovirus). On January 6, India reported six confirmed cases of HMPV, sparking concerns over another potential outbreak. Here’s a detailed look at what this virus is, how it spreads, and what India is doing to stay prepared.

1. What is HMPV and how is it similar to COVID-19?

HMPV (Human Metapneumovirus) is a respiratory virus that primarily causes symptoms like cough, fever, breathing difficulty, and nasal congestion. According to the US Centers for Disease Control and Prevention (CDC), it belongs to the Pneumoviridae family, which also includes the Respiratory Syncytial Virus (RSV) known for causing lung infections, especially in young children.

Unlike SARS-CoV-2, the virus responsible for COVID-19, HMPV is an RNA virus from a different family. However, both viruses exhibit similar symptoms, making early diagnosis challenging.

Common symptoms of HMPV include:

• Cough
• Fever
• Blocked nose
• Shortness of breath

While COVID-19 cases were found to be seasonal, peaking in colder months, HMPV can spread throughout the year, with peaks during spring and winter.

2. How does HMPV spread, and how contagious is it?

Although the transmission rate of HMPV is lower than that of COVID-19, it spreads in similar ways:

• Droplets: Infected individuals can spread the virus through respiratory droplets when they cough, sneeze, or talk.
• Direct contact: Touching an infected person’s face, eyes, or mouth can result in transmission.
• Contaminated surfaces: HMPV can survive on surfaces like door handles and mobile phones, increasing the risk of indirect transmission.
• Airborne particles: In crowded or poorly ventilated spaces, airborne particles may remain suspended, raising the risk of infection.

3. Can HMPV cause fatalities like COVID-19?

According to China’s Center for Disease Control and Prevention (CDC), fatalities due to HMPV are rare but possible in individuals with pre-existing medical conditions or those who are more vulnerable, such as:

• Children under 5 years
• Elderly individuals over 65 years
• Premature infants
• People with weakened immune systems or chronic respiratory conditions like asthma

4. How is HMPV diagnosed, and when should you get tested?

HMPV can be diagnosed using methods similar to COVID-19 testing. If symptoms persist or worsen, individuals should get tested at either government hospitals or private labs.

Sample Collection Methods

• Nasopharyngeal swab: A swab is inserted into the nose to collect a sample.
• Throat swab: A sample is taken from the throat using a cotton swab.
• Blood sample: In some cases, a blood test may be required.
• Sputum sample: If the patient has mucus, it can also be tested.

Testing Techniques

• RT-PCR: The most accurate method, detecting HMPV’s genetic material.
• Culture test: Involves growing the virus in a lab, though results may take longer (up to three days).
• Antibody test: Detects antibodies in the blood but is considered less reliable.

5. Is there a vaccine or specific treatment for HMPV?

Currently, there is no vaccine or specific antiviral treatment available for HMPV. Treatment primarily focuses on relieving symptoms through supportive care, including:

• Fever reducers and pain relievers
• Hydration
• Use of humidifiers to ease breathing

Patients with severe symptoms or underlying conditions may require hospitalization and oxygen support, similar to COVID-19 cases.

6. What precautions should be taken to prevent HMPV transmission?

Health experts recommend following COVID-like precautions to reduce the risk of HMPV infection:

• Wearing masks in crowded or poorly ventilated spaces
• Maintaining social distance
• Regular handwashing with soap or using an alcohol-based sanitizer
• Avoiding direct contact with infected individuals
• Disinfecting frequently touched surfaces

7. Will lockdowns be imposed to control HMPV?

No lockdowns have been imposed anywhere due to HMPV, and India is not currently facing a situation that warrants such measures.

8. Are antibiotics effective against HMPV?

No, antibiotics do not work against HMPV since it is a viral infection, and antibiotics only treat bacterial infections. Supportive care is the primary treatment option.

9. Where have HMPV cases been reported in India?

As of now, six HMPV cases have been reported in India:

• Ahmedabad: A 2-month-old baby from Rajasthan tested positive.
• Bengaluru: Two cases were reported in a 3-month-old and an 8-month-old child.
• West Bengal: A 5-month-old child is undergoing treatment at a private hospital.
• Chennai: Two cases have been detected, but further details are awaited.

10. What is the Indian government’s response to HMPV?

Union Health Minister JP Nadda assured that the government is closely monitoring the situation. He stated, “HMPV is not a new virus; it was first identified in 2001. WHO is keeping a close watch on the situation, and we are awaiting further reports.”

Meanwhile, the ICMR (Indian Council of Medical Research) and IDSP (Integrated Disease Surveillance Programme) have robust systems in place to monitor Influenza-like Illness (ILI) and Severe Acute Respiratory Infections (SARI). According to the health ministry, there has been no significant surge in ILI or SARI cases so far.

11. What is the origin of HMPV?

HMPV was first identified in 2001 by a group of Dutch scientists studying respiratory illnesses in children. Cases have since been reported in the US, Canada, and Europe. Recent media reports suggest that the virus may have spread to India via travelers from China.
