Daily Current Affairs : 7-January-2025

Recently, there has been an increase in respiratory illnesses in China, linked to a virus known as Human Metapneumovirus (HMPV). This has raised concerns that it could lead to another pandemic. However, the World Health Organization (WHO) has not declared a new pandemic, issued emergency alerts, or labeled the situation as a health crisis related to HMPV. Let’s explore more about this virus and its impact.

What is Human Metapneumovirus (HMPV)?

Discovery and Characteristics:

  • HMPV was first discovered in 2001 by researchers in the Netherlands.
  • It causes respiratory infections that are similar to the flu or COVID-19, including symptoms like cough, fever, sore throat, and runny nose.
  • The virus belongs to the Pneumoviridae family, which also includes Respiratory Syncytial Virus (RSV), measles, and mumps.

Global Presence:

  • HMPV is not confined to China; it is found worldwide and is recognized as a common respiratory pathogen.
  • There is currently no vaccine available for HMPV.
Symptoms and Severity of HMPV

Common Symptoms:

  • The symptoms of HMPV resemble those of many other respiratory infections, including:
    • Cough
    • Fever
    • Sore throat
    • Runny nose
    • Wheezing
  • These symptoms typically last between 2 to 5 days and usually resolve on their own.

Vulnerable Groups:

  • While most cases are mild, certain groups are more at risk of severe complications, including:
    • Young children
    • The elderly
    • People with weakened immune systems
  • These individuals are more likely to develop conditions like pneumonia or bronchiolitis, which may require medical attention.
How HMPV Spreads

HMPV spreads easily through close contact, such as handshakes, or by touching surfaces contaminated with the virus. It is highly transmissible, especially during the colder months when respiratory infections tend to peak.

Seasonal Impact of HMPV

HMPV circulates more commonly during the winter and spring seasons, overlapping with the transmission of other respiratory viruses, such as RSV and influenza. This seasonality contributes to the higher number of infections during these months.

Important Points
  • Human Metapneumovirus (HMPV) was discovered in 2001 and causes respiratory infections similar to flu and COVID-19.
  • Symptoms include cough, fever, sore throat, runny nose, and wheezing, typically lasting 2-5 days.
  • HMPV is globally present and not limited to China; it is a common respiratory pathogen.
  • No vaccine is available for HMPV.
  • Vulnerable groups at higher risk for severe complications include young children, the elderly, and those with weakened immune systems.
  • Severe complications (like pneumonia or bronchiolitis) affect a small percentage (5-16%) of cases.
  • HMPV spreads through close contact and contaminated surfaces.
  • Seasonal impact: HMPV circulates more frequently during winter and spring, along with other respiratory viruses like RSV and influenza.
  • The World Health Organization (WHO) has not declared a pandemic or health crisis related to HMPV.
Why In News

The recent surge in respiratory illnesses in China, linked to Human Metapneumovirus (HMPV), has sparked fears of another pandemic, although experts caution that the virus typically causes mild illness and is not currently a global health threat.
