On June 3, the chief physician of a third-class hospital infection control center said: "according to sporadic reports in recent years, human metapneumonia virus does exist in patients with respiratory tract infection, including upper and lower respiratory tract infection. Accidental local outbreaks should be paid attention to in respiratory infection surveillance, and should not be ignored in the etiological study of respiratory tract infection. At present, there is no vaccine, and there is also a lack of specific antiviral drugs. the disease is generally mild after infection, and individuals should be vigilant to develop into severe cases. It is hoped that the human metapneumovirus vaccine will be developed as soon as possible. " (health Times)
