HUMAN METAPNEUMOVIRUS (HMPV)
- Human metapneumovirus (HMPV) is a respiratory virus that typically causes mild infections resembling the common cold. Discovered by researchers in 2001, it is part of the Pneumoviridae family, which also includes respiratory syncytial virus (RSV), as well as the viruses responsible for measles and mumps.
- HMPV can lead to infections in both the upper and lower respiratory tracts and is most commonly observed during the winter and early spring months. Children, older adults, and individuals with weakened immune systems are at higher risk of infection and potential complications.
- The symptoms, which are similar to those of a common cold, include cough, nasal congestion or runny nose, sore throat, fever, and wheezing. The incubation period is estimated to be three to six days.
- For most individuals, the illness resolves on its own within a few days with adequate rest and supportive care. However, in some cases, complications like bronchitis or pneumonia may develop, necessitating medical attention
- HMPV is transmitted through direct contact with an infected individual or by touching surfaces contaminated with the virus. This includes exposure to respiratory droplets from coughs and sneezes, physical interactions like handshakes or hugs with an infected person, or handling items such as doorknobs, phones, or keyboards that carry the virus, followed by touching the face, nose, eyes, or mouth.
- Currently, there is no vaccine or specific antiviral treatment available for HMPV. Most individuals manage symptoms with over-the-counter medications for fever and pain, possibly supplemented by a decongestant.
- Antibiotics are ineffective against HMPV. However, the virus can be prevented by practicing good hygiene, such as frequent handwashing with soap and water, avoiding close contact with infected individuals, refraining from touching the face, and wearing a mask to prevent spreading the virus if you suspect you are infected. Individuals with respiratory conditions like asthma or COPD should take extra precautions to reduce their risk of infection
