Human metapneumovirus (HMPV) is a common respiratory virus that affects people of all ages, particularly young children and older adults. Although HMPV has existed globally for over 60 years, it was only identified in 2001. In Pakistan, cases have been reported since 2004, with 21 instances particularly noted in Islamabad. HMPV infections typically peak during late winter and spring in temperate regions. In recent reports, 327 HMPV cases have been recorded, a notable increase compared to 225 cases the previous year.

HMPV can lead to pneumonia, bronchiolitis, or bronchitis, especially among those at high risk of severe illness. The virus spreads through infectious respiratory droplets in close contact with an infected person. HMPV is widespread and has been circulating among humans for decades. Since December 2024, China has reported a surge in cases, with the United States also noting cases since April 2024.

Although no vaccine currently exists, HMPV remains highly contagious, spreading through coughing and sneezing. Its seasonal peak in temperate regions highlights the need for public awareness and preventive care.

To conclude, a multifaceted approach is essential, as HMPV poses a significant yet underrecognised health threat in Pakistan.
