When I took the subway recently
It seems that more people wear masks.
Recently, many people have "cold" nasal congestion symptoms.
Many people suspect that it is the flu.
Or mycoplasma infection
In fact, apart from influenza and mycoplasma infection,
The human metapneumovirus has also quietly attacked.
What is human metapneumovirus?
What are the symptoms of infection?
Human metapneumovirus infection is increasing gradually.
Recently, the China Center for Disease Control and Prevention released the national monitoring of respiratory infectious diseases, and acute respiratory infectious diseases showed a continuous upward trend, among which human metapneumovirus infection gradually increased.
What is human metapneumovirus? Human metapneumovirus is a common virus that can cause acute respiratory infection. Compared with traditional respiratory infection viruses such as influenza, human metapneumovirus is relatively "young" and its discovery time is late. In 2001, Dutch scholars first detected the virus from nasopharyngeal aspirate samples of children with respiratory tract infection caused by unknown pathogens. Although it was discovered late, serological studies show that it has existed in humans for more than 60 years and is distributed all over the world.
How does human metapneumovirus spread? The mode of transmission of human metapneumovirus is similar to that of most respiratory viruses, mainly through the following channels:
1. droplet transmission: when an infected person coughs or sneezes, the virus will spread with droplets;
2. Contact transmission: close contact with people infected with metapneumovirus, or contact with objects contaminated by metapneumovirus (such as doorknobs, mobile phones, toys, etc.), and then touch your eyes, nose or mouth, causing the virus to enter the body.
However, it should be noted that human metapneumovirus has certain viability in the environment, especially on the surface of objects, and the virus can survive for several hours. Therefore, it is very important to do a good job in daily life.

This virus is easily infected by the whole population.
Human metapneumovirus usually occurs in winter and spring because it is dry and easy to spread in winter and spring. The whole population is generally susceptible to human metapneumovirus, and patients are the most contagious at the beginning of the disease. The immune protection time of patients is relatively short, and they are prone to repeated infection. It should be noted that the patient’s incubation period and terminal illness are contagious after infection.
The incubation period of human metapneumovirus infection is generally 3-6 days, and the symptoms of human metapneumovirus infection are similar to those of influenza, but the main manifestations of human metapneumovirus infection are colds, fever, cough, runny nose and other symptoms, while influenza virus will have high fever and general fatigue.
Authorized map, reprint is risky.
1. Common symptoms: upper respiratory tract infection symptoms such as cough, fever, nasal congestion and shortness of breath;
2. Mild infection: For most people, human metapneumovirus infection is a self-limited disease, and most people gradually relieve their symptoms in about 1 week;
3. Severe infection: For the following high-risk groups, human metapneumovirus may cause severe lower respiratory tract infection:
① Children under 5 years old: it may lead to bronchiolitis or severe pneumonia;
② Elderly people: It may induce lung infection or aggravate asthma;
③ People with low immunity: For example, those who receive organ transplantation or hematopoietic stem cell transplantation may have severe lung inflammation after infection.
It should be noted that at present, there are no specific drugs and vaccines for human metapneumovirus infection, and symptomatic support treatment is the main one.
During illness, it is necessary to ensure adequate energy and nutrition intake, pay attention to the balance of water and electrolyte, and maintain internal environment stability. Blind or improper use of antibacterial drugs, especially the combination of broad-spectrum antibacterial drugs, should also be avoided. Virus infection is often not complicated with bacterial infection in the early stage.
After being infected with the virus, you can pay close attention to the changes of your condition. Once you have symptoms such as dyspnea and persistent high fever, you should seek medical advice in time and use drugs rationally under the guidance of a doctor.
How to prevent human metapneumovirus infection
Because the mode of transmission of human metapneumovirus is similar to that of most respiratory viruses, we can:
Good habits: Develop good hygiene habits such as washing hands frequently, wearing masks and cleaning frequently.
Regular ventilation: open the window regularly every day to keep the indoor air fresh and unobstructed.
Less gathering: Try to avoid places where people gather or where the space is closed.
Improve immunity: eat a balanced diet, exercise moderately, work and rest regularly, and keep healthy.

In a word, keeping good living habits, wearing masks when going to crowded places, and taking preventive measures such as frequent hand washing, frequent ventilation and scientific disinfection can effectively reduce the chance of infection.
