A little-known respiratory virus called human metapneumovirus (HMPV) is spreading in multiple states, including New Jersey, drawing attention from the CDC; most people have likely already had it by age five, making awareness of symptoms important as cases rise.
A little-known respiratory virus called human metapneumovirus (HMPV) is rising nationwide as flu season winds down, with wastewater data showing high community activity. Most infections are mild and last 2–5 days, but HMPV can progress to pneumonia, bronchitis, or trigger asthma flares, particularly in young children, older adults, and those with weakened immune systems. There is no vaccine and no specific treatment. Diagnosis is usually clinical, sometimes confirmed by nasal/throat swabs, and transmission occurs via droplets and contaminated surfaces. Prevention centers on staying home when sick, hand-washing, and keeping surfaces clean. Most people will be infected with at least one HMPV strain in their lifetime.
A highly contagious human metapneumovirus (HMPV) is surging on the West Coast, with wastewater data showing elevated levels in Northern California and rising cases nationwide; there is no vaccine or specific treatment, and care is limited to supportive measures. Common symptoms include cough, fever, nasal congestion and shortness of breath, with young children, older adults and the immunocompromised at higher risk of severe illness; prevention focuses on hand hygiene, masking when sick and avoiding close contact.
Public health officials report rising human metapneumovirus (HMPV) infections in parts of California, with wastewater data showing higher concentrations in Merced, Novato and Sunnyvale; there is no vaccine or specific antiviral for HMPV, and most infections are mild but can be severe for immunocompromised individuals, young children, and older adults. The virus typically peaks in late winter to spring and was disrupted by COVID-19, though seasonality is returning. Prevention focuses on handwashing, cleaning touched surfaces, improving ventilation, and avoiding sick people; consult a clinician if symptoms worsen. LA County levels are currently low to moderate, signaling a cautious but not alarmed public health situation.
A little-known respiratory virus, human metapneumovirus (HMPV), is surging on the West Coast, with wastewater surveillance showing elevated activity in Northern California and a January peak; there is no vaccine or specific treatment, and the virus can cause cough, fever and breathing difficulties, posing higher risks to young children, older adults and the immunocompromised, while data also show rising activity in the Midwest and Northeast per CDC surveillance.
Wastewater data show high levels of human metapneumovirus (HMPV) across Northern California, with Redwood City reporting the strongest signals, as national cases rise since October 2025. HMPV typically causes cold-like symptoms but can lead to middle-ear infections and life-threatening asthma; there is no vaccine, and diagnosis requires lab testing. Most people recover with rest and fluids, while severe cases may need hospitalization. Preventive steps include good hand hygiene, cleaning surfaces, and staying home when sick.
Public health experts warn that a vaccine-free human metapneumovirus (HMPV) is rising in Northern California, with wastewater data showing high levels in cities like Redwood City and broader spread along the Bay Area and Napa. National cases have been trending up since October 2025. HMPV typically causes cold-like symptoms but can lead to more serious issues such as wheezing, asthma attacks, middle-ear infections, pneumonia, and, in vulnerable individuals, death. There is no vaccine to prevent HMPV; prevention focuses on handwashing, cleaning surfaces, staying home when sick, and seeking medical care if symptoms worsen. Most people recover with rest and fluids, with treatment in severe cases including oxygen, steroids, and IV fluids as needed.
Wastewater data show high concentrations of human metapneumovirus (HMPV) across Northern California, signaling a regional uptick in a common respiratory virus that can cause cold- or flu-like illness and, in some people (especially young children, seniors, and the immunocompromised), more serious disease; there is no vaccine or antiviral treatment, so prevention centers on hygiene and staying home when sick, with symptoms typically lasting 2–5 days.
Human metapneumovirus (HMPV), a potentially fatal respiratory virus that is relatively unknown, is surging in Australia, with over 1,000 cases reported last week in New South Wales alone. HMPV can cause upper and lower respiratory disease, posing a greater risk to young children, older adults, and immunocompromised individuals. While it typically presents as a mild infection similar to the common cold, complications can lead to bronchitis or pneumonia, especially in those with weakened immune systems. The surge in cases may be underestimated due to limited testing, as patients already positive for COVID-19 or the flu may not be tested for HMPV.
The Centers for Disease Control and Prevention (CDC) reported a surge in human metapneumovirus (HMPV) cases, likely due to the lack of immunity people have to the virus after lockdowns. HMPV is a common cause of illness in the colder months and typically causes cold-like symptoms, but it can lead to more severe respiratory illnesses in infants, young children, older adults, and people with weakened immune systems. There is currently no cure or vaccine for HMPV, but preventive measures such as regular hand hygiene and avoiding close contact with infected individuals can help reduce its spread.
Cases of human metapneumovirus (HMPV), a respiratory virus similar to RSV, have surged in the US during late winter and spring. HMPV is transmitted through large droplets and is especially transmissible in a household setting. Symptoms include upper and lower respiratory tract infections, with hospitalization more common in children under 5 or older adults. HMPV is usually less severe than RSV, influenza, or COVID-19. The recent uptick in HMPV cases likely reflects loss of population immunity during the last three years. Basic hand hygiene and routine immunizations can help prevent the spread of HMPV.
Human metapneumovirus (HMPV) is a virus that causes symptoms similar to those of a cold, flu, and COVID-19. Cases of HMPV have surged in the US, with hospitals' intensive care units filling up with young children and elderly patients sick with the virus. HMPV is not a new virus and is believed to have circulated among humans completely undetected since at least the 1950s. While most people who contract it don't develop serious symptoms, young children and the elderly are the most vulnerable to the virus, and in severe cases, it can be fatal.
The Centers for Disease Control and Prevention (CDC) is warning about a new virus called human metapneumovirus (HMPV) that causes respiratory symptoms similar to influenza and Covid-19. HMPV can lead to severe complications for young children, seniors, and immunocompromised individuals, and there is no vaccination to guard against its worst effects. The surge in HMPV cases this spring is a worrying sign, and the CDC recommends that doctors test patients exhibiting respiratory symptoms for HMPV, particularly in its peak seasons, the winter and the spring. Moderna recently finished a study of an mRNA vaccine against HMPV and parainfluenza that could have an impact on the dangerousness of the virus.
Cases of the little-known respiratory virus, hMPV, have spiked 36% higher than average this season, particularly for young children and seniors. Symptoms include cough, running nose, fever, and wheezing. While there are no antiviral therapies to treat hMPV and no vaccines available, over-the-counter cold meds can be used to treat symptoms. Healthcare providers recommend testing for COVID-19 and influenza if respiratory symptoms develop, especially for vulnerable populations. Lessons learned from the pandemic can help prevent the spread of hMPV and other viruses.
The human metapneumovirus (HMPV), a little-known respiratory virus, caused a surge in hospitalizations and illnesses this spring, with cases surging about 36 percent in mid-March, according to the Centers for Disease Control and Prevention. HMPV causes symptoms similar to COVID-19 or RSV, but doctors don’t usually test for it outside of a hospital setting. The virus can lead to complications and intensive care for vulnerable patients, but in most cases, the symptoms will resolve without treatment after several days.
