The cases of Human Metapneumovirus (HMPV) are on the rise in Chinaraising concerns on social networks about the possibility of a new pandemic similar to COVID-19. However, experts guarantee that the HMPV It is a virus known for decades and has a low risk of generating a global health crisis along the lines of Covid-19 pandemic.
What is HMPV?
First identified in the Netherlands in 2001, the HMPV It is a common respiratory virus around the world. He belongs to the same family as Respiratory Sincient Virus (RSV)known for causing respiratory infections in young and elderly children. For most people, HMPV manifests itself similarly to a common cold, but can evolve into severe respiratory diseases in vulnerable groups such as young children, elderly and people with weakened immune system.
HMPV symptoms
The most common symptoms of HMPV They include cold, cough, fever, nasal congestion and difficulty breathing. In more severe cases, the virus can cause bronchitis or pneumoniaaffecting both the upper and lower airways. The evolution of symptoms usually occurs between three and six days after infection, and their duration may vary.
How is HMPV transmitted?
The transmission of HMPV occurs similar to that of other respiratory viruses, such as the COVID-19. The virus spreads through direct contact with infected people or contaminated surfaces. Contamination occurs when the hands touch the mouth, nose or eyes after contact with the virus. Like RSV, HMPV is seasonal, predominating in the winter months.
Prevention measures
HMPV prevention involves practices similar to those recommended for COVID-19. This includes:
- Wash your hands regularly and properly.
- Avoid close contact with sick people.
- Use masks in public places if there are respiratory symptoms.
As there is no specific treatment for HMPV, the focus is on reducing transmission. Covering the mouth at coughing and using disposable scarves are essential measures to limit propagation.
The situation in China
In December 2024, diseases control authorities of the China They intensified the monitoring of emerging respiratory diseases, providing for an increase in cases during the winter. Data indicate a peak of HMPV especially among children under 14 in the northern provinces of the country. Images of hospitals in China circulated on social networks, increasing the fear of a new public health crisis.
Is HMPV a global threat?
Experts, like the teacher Peter Openshawfrom Imperial College London, discard the possibility of the HMPV causing a pandemic similar to the COVID-19. Although respiratory viruses may evolve, HMPV behavior does not suggest changes that would increase its potential global risk. The teacher points out that this is a seasonal virus that causes more severe outbreaks during the winter months.
Comparison with Covid-19
Despite similarities in symptoms and transmission, HMPV is less aggressive than SARS-COV-2, responsible for COVID-19. HMPV has been circulating for decades, and most people are exposed to childhood virus. Moreover, there is no evidence of recent mutations that make it more dangerous.
The importance of vaccines
Although HMPV is not considered a pandemic threat, experts warn of the need for advances in research on respiratory disease vaccines. According to Professor OpenShaw, there are several ongoing clinical trials, an essential step in mitigating the impact of viruses such as HMPV and RSV.
The situation in the United Kingdom
In the United Kingdom, the HMPV Follows the expected pattern for winter. Data from the UK Health Safety Agency (UKHSA) indicate a modest increase in cases between December 23 and 29, 2024, aligned with the seasonal behavior of the virus. Most infections are light, with symptoms similar to a common cold.
Other respiratory diseases in circulation
In addition to HMPV, other respiratory viruses, such as flu and RSV, are also in circulation during winter. Health officials recommend maintaining hygiene practices and, in case of serious symptoms, seek medical attention to avoid complications.
Global concern with respiratory diseases
Although HMPV is not considered a new global threat, increased cases in China and other countries highlights the need for constant surveillance. Experts reinforce the importance of preventive measures and continuous efforts to develop vaccines against respiratory infections.
Summary for those in a hurry
- Cases of HMPV increase in Chinaespecially among children.
- Virus has been known since 2001 and has symptoms similar to a cold.
- Transmission occurs by human contact or contaminated surfaces, as in the case of COVID-19.
- Experts rule out the risk of global pandemic as HMPV is seasonal and less aggressive.
- There is no specific treatment; Preventive measures such as hygiene and masks are recommended.
- Research on vaccines against respiratory disease is underway.
