HPIVs Surge in China: Kids Under 5 Most Affected

In China, human parainfluenza virus (HPIV) infections have seen a recent increase, particularly affecting children aged five and younger. Data from the Chinese Center for Disease Control and Prevention indicates a rise in the positivity rate for HPIVs, which are common cold-like respiratory viruses. For the week commencing April 6, the HPIV positivity rate was 6.9%, a slight uptick from previous weeks.

While general influenza activity is decreasing, HPIVs, rhinovirus, and respiratory syncytial virus remain in circulation. Health authorities recommend that the public continue to adopt personal protective measures, including wearing masks and maintaining hand hygiene. Experts highlight that HPIVs are less prone to mutation than influenza and commonly affect infants and young children, often presenting with a barking cough or hoarse voice, distinguishing them from influenza's sudden high fever and body aches.
