HMPV & Spread
Recent reports of human metapneumovirus (HMPV) cases in China have sparked fears of another pandemic. However, health experts emphasize that HMPV is not new and behaves differently from Covid-19. Here’s what you need to know about this flu-like virus.
What Is HMPV?
First identified in 2001 in the Netherlands, HMPV is a respiratory virus that spreads through:
- Direct contact with an infected person
- Touching contaminated surfaces
For most, the virus causes mild upper respiratory tract infections and is almost indistinguishable from the flu.
Common Symptoms Include:
- Cough
- Fever
- Blocked nose
Those most at risk are:
- Young children, particularly under age 2
- The elderly
- Individuals with weakened immune systems, such as cancer patients
Severe cases can lead to lung infections, causing wheezing, breathlessness, and even symptoms of croup.
Why Are HMPV Cases Rising in China?
Like many respiratory viruses, HMPV thrives in cold weather, particularly in late winter and spring. In northern China, low temperatures and more indoor gatherings have contributed to an increase in cases.
Health experts note that:
- The rise in HMPV cases aligns with seasonal patterns.
- Similar trends are being observed in other northern hemisphere countries, such as the U.S.
The World Health Organization (WHO) has confirmed no unusual outbreak patterns and no overwhelming pressure on China’s healthcare system.
What About HMPV in the UK?
In the UK, HMPV cases have been steadily rising since October 2024, with a noticeable spike in December. However:
- The UK Health Security Agency (UKHSA) says this aligns with normal seasonal trends.
- No unusual activity has been reported in GP surgeries or hospitals.
Could HMPV Lead to Another Pandemic?
Experts widely agree that HMPV is not a Covid-like threat. Key reasons include:
- HMPV is not new: It has been globally present for decades.
- Existing immunity: Most people have been exposed to HMPV at least once by age 5 and have some level of immunity.
- No human-to-human mutations: Unlike novel viruses, HMPV hasn’t shown signs of evolving into a pandemic-level threat.
How to Protect Yourself from HMPV and Similar Illnesses
While HMPV isn’t a major cause for alarm, taking precautions can reduce your risk of infection:
- Wear a mask in crowded spaces.
- Avoid crowds if you are at higher risk.
- Wash your hands regularly with soap.
- Dispose of tissues securely after use.
- Vaccinate against other respiratory illnesses, such as the flu.
In the UK, at-risk groups like pregnant women and adults aged 75 to 79 are also encouraged to get the RSV vaccine.
A Final Word from Experts
While the rise in HMPV cases is concerning, it is not a sign of another global pandemic. Sensible hygiene practices and staying informed are your best defenses.
