Northern California Faces hMPV Surge

SACRAMENTO, CA - March 4, 2026 - Northern California is currently experiencing a surge in cases of Human Metapneumovirus (hMPV), a common respiratory virus that, while often mild, is increasingly contributing to strain on the region's healthcare systems. Health officials are urging residents, particularly young children and older adults, to take preventative measures as cases continue to climb.

Dr. Olivia Kasowski, Sacramento County Public Health Officer, confirmed the rising incidence of hMPV, stating, "We're seeing a notable increase in cases across Northern California. While it's not a virus that consistently makes headlines, it's capable of causing severe illness, especially in vulnerable populations."

Understanding Human Metapneumovirus (hMPV)

hMPV is a virus that causes respiratory infections, often presenting with symptoms similar to those of the common cold, influenza (the flu), or Respiratory Syncytial Virus (RSV). These symptoms typically include a runny nose, cough, fever, and sometimes sore throat. However, hMPV can progress to more serious conditions, such as pneumonia and bronchitis, requiring hospitalization. The CDC notes that hMPV typically circulates during the cooler months, from fall through spring, mirroring the patterns of other respiratory illnesses. While infections are common, the current uptick is drawing concern.

Why the Current Surge is Concerning

What separates this surge from typical seasonal increases? The convergence with ongoing respiratory illness activity--including lingering influenza strains and the continued presence of COVID-19--is creating a complex diagnostic challenge for healthcare providers. Dr. Kasowski explains, "It can look like RSV or flu. That makes accurate and timely diagnosis a little tricky, adding to the pressure on testing resources and potentially delaying appropriate care."

The increased number of hMPV cases is placing additional pressure on already stretched hospital resources. "We are seeing some stress on our hospital system," Dr. Kasowski acknowledged, highlighting the potential for longer wait times and limited bed availability, particularly for those requiring respiratory support. This strain comes at a time when many hospitals are still recovering from the impacts of the COVID-19 pandemic and facing staffing shortages.

Who is Most at Risk?

While anyone can contract hMPV, certain demographics are disproportionately affected. Young children, especially those under the age of five, and older adults (those 65 and older) are at the highest risk of developing severe illness. Individuals with weakened immune systems, chronic lung or heart conditions, or other underlying health problems are also considered more vulnerable. Parents of young children are being urged to be particularly vigilant for symptoms and to consult with their pediatrician if they have concerns.

Treatment and Prevention

Currently, there is no specific antiviral treatment for hMPV. Treatment focuses on supportive care, managing symptoms, and preventing complications. This includes rest, fluids, and over-the-counter medications to relieve fever and cough. In severe cases, hospitalization may be required for oxygen therapy or other respiratory support.

However, the most effective strategy remains prevention. Public health officials strongly recommend the following measures:

  • Frequent Handwashing: Wash hands thoroughly with soap and water for at least 20 seconds, especially after being in public places or contact with sick individuals.
  • Covering Coughs and Sneezes: Use a tissue or your elbow to cover your mouth and nose when coughing or sneezing.
  • Avoid Close Contact: Limit close contact with individuals who are sick.
  • Stay Home When Sick: If you are feeling unwell, stay home from work or school to prevent spreading the virus.
  • Surface Disinfection: Regularly disinfect frequently touched surfaces, such as doorknobs, light switches, and countertops.
  • Ventilation: Improve ventilation by opening windows or using air purifiers.

Looking Ahead

Health officials are continuing to monitor the spread of hMPV closely and are collaborating with healthcare providers to ensure adequate resources are available. The situation is evolving, and further updates will be provided as new information becomes available. Residents are encouraged to stay informed by visiting the Sacramento County Public Health website (https://www.saccounty.gov/publichealth) and the CDC website (https://www.cdc.gov/hmpv/index.html) for the latest guidance and recommendations.
