If you mean the “new virus going around” people are talking about online, the most likely candidates are human metapneumovirus (HMPV) , norovirus , COVID-19 , mpox , or in some regions Oropouche virus —there usually isn’t just one single virus, and headlines often mix together several active outbreaks or seasonal waves.

Quick Scoop

  • HMPV has been called a “mystery virus” in some media, but experts say it is not new and is a known seasonal respiratory virus.
  • Norovirus has been notably active in recent seasons and can cause vomiting and diarrhea, which is why some people describe it as “going around” fast.
  • COVID-19 is still circulating, along with other respiratory viruses.
  • Mpox , Oropouche virus , and Nipah have also appeared in current outbreak monitoring reports, though these are not the same thing as a general community “new virus”.

What to watch for

  • Respiratory symptoms: cough, fever, sore throat, congestion, shortness of breath.
  • Stomach symptoms: vomiting, diarrhea, nausea, dehydration.
  • Rash or unusual sores: can point to mpox or other conditions.
  • Travel-related illness: if you recently traveled, that changes what’s most likely.

When to get care

  • Trouble breathing.
  • Chest pain.
  • Confusion.
  • Signs of dehydration.
  • High fever that won’t settle.
  • A worsening rash or severe weakness.
