  Human Metapneumovirus (HMPV) has seen a surge in cases recently.   

  As winter respiratory illnesses rise, the China Centers for Disease Control and Prevention (CDC) recently reported an uptick in acute respiratory infections, with human metapneumovirus (HMPV) infections increasing. The primary strain circulating this season is the H1N1 subtype of the flu virus.

• What is Human Metapneumovirus (HMPV)?

  Human Metapneumovirus (HMPV) is a common virus that causes acute respiratory infections. Similar to most respiratory viruses, it spreads primarily through droplets and direct contact. Winter and spring are peak seasons for HMPV, particularly in crowded areas where outbreaks are more likely. Individuals infected with HMPV remain contagious from the end of the incubation period through the acute phase of the illness. It's important to note that immunity to HMPV is short-lived, meaning individuals can become reinfected.

• Symptoms of HMPV

  The symptoms of HMPV are similar to those of the flu, including fever, cough, and runny nose. The incubation period typically ranges from 3 to 6 days, and the virus affects people of all ages. There is currently no vaccine or specific antiviral treatment for HMPV, and management typically focuses on supportive care to alleviate symptoms.

• Is the Recent Strain a New Variant?

  Regarding rumors of a new variant of HMPV causing dizziness as a primary symptom, Dr. Li Dong, a physician, clarified in a recent media interview that no new strains of respiratory viruses have been identified. It's common for respiratory infections to manifest with a variety of symptoms, including dizziness, headache, fatigue, and muscle aches.

  Recent surveillance data from the National Acute Respiratory Infectious Disease Sentinel System showed high positive rates for influenza, rhinovirus, HMPV, and Mycoplasma pneumoniae among patients with flu-like symptoms visiting hospitals.

• Should We Be Worried About HMPV?

  Doctors note that while HMPV is more common in autumn and winter, it generally causes mild illness and is unlikely to result in severe complications. There's no need to be overly concerned. Preventative measures such as frequent handwashing, wearing masks, and avoiding crowded or poorly ventilated spaces can help reduce the risk of infection.

• 6 Tips for Effective Prevention

  The CDC offers the following advice to help prevent the spread of respiratory infections:

1.Wash hands at critical moments: Wash your hands before preparing or eating food; after using the restroom, coughing, sneezing, or blowing your nose; after caring for a sick person; and after handling trash.

2.Wear a mask properly: It's recommended to wear a mask when using public transport or in crowded, enclosed spaces.

3.Ventilate your environment regularly: Open windows and allow fresh air to circulate.

4.Boost your immune system: Maintain a healthy lifestyle to strengthen your immunity.

5.Get adequate sleep: Ensure you are getting enough rest to support overall health.

6.Monitor your health: Pay attention to any symptoms, and seek medical attention if they worsen.
