Human Metapneumonovirus (HMPV): Pandemic or Paranoia ?

The world is still recovering from the overwhelming impact of the COVID-19 pandemic. News of any respiratory virus breakout raises public alarm. The Human Metapneumonovirus (HMPV) is not spared any skepticism with the media spotlights pointed its way. It does however stir the question: Is HMPV gearing up to become the next global health crisis or is the comparison to COVID-19 exaggerated? 

 What is HMPV?: The Human Metapneumonovirus was identified in early 2000’s, this virus is not new to the world. It belongs to the Paramyxoviridae family and shares similarities with viruses responsible for respiratory tract infections. The virus causes mild cold-like symptoms in children, elderly and immunocompromised individuals. In severe cases it can lead to: bronchiolitis, pneumonia, and other lower respiratory tract complications. 

Both COVID-19 and HMPV are typically transmitted through mucosal or salivary droplets, direct contact with infected personnel and contaminated surfaces. COVID-19’s transmissibility was driven by the SARS-CoV-2 virus’ ability to spread asymptomatically and rapidly. Although HMPV is contagious it is not known to spread explosively. HMPV infections generally result in milder symptoms and significantly lower mortality rates unlike COVID-19 with its potential to cause severe respiratory distress, widespread systemic inflammation, severe complications in high-risk groups, and high mortality. 

    

 It is believed that COVID-19’s global reach was mediated by its high basic reproduction number and delayed response in containing the virus. HMPV has circulated globally for years and it is considered more of a seasonal infection like flu and RSV than a pandemic with the potential to overwhelm the healthcare system. 

The major cause of public concern regarding HMPV is the lack of vaccine or specific antiviral treatment which has prompted public health experts to prioritize continued surveillance, research and vaccination development. HMPV is a noteworthy respiratory virus that deserves attention, especially for vulnerable populations however, current data does not support the idea that it will become the next global pandemic. The general public is responsible for practising, preventative measures like good hygiene and avoiding misleading information.
