Central Disease Control and Prevention Release Reminder!, Just now, the detection rate of this virus has reached a significant peak in the United States. The virus | lung | disease control
The Chinese Center for Disease Control and Prevention (CDC) released health tips today regarding human lung viruses.
From January to April 2023, there was a significant peak in the detection rate of human parathyroid virus in samples voluntarily sent by various laboratories in different regions of the United States, which has attracted some international attention. However, since late April, the positive rates of pulmonary antigen and nucleic acid in Americans have continued to rapidly decline, and by late May, they had dropped to lower levels. The analysis of respiratory infectious disease monitoring data from 2009 to 2019 by the Chinese Center for Disease Control and Prevention shows that among the 8 viruses that cause acute respiratory infections, human lung viruses rank 8th with a positive rate of 4.1%, far lower than the 28.5% of influenza viruses. From September 2022 to April 2023, the positive rate of human parathyroid virus in hospitalized children with acute respiratory infections in Beijing was 2.6%, and there was no significant peak in the epidemic. Since the beginning of this year, personnel exchanges between China and the United States have gradually resumed, and there is a possibility that people infected with the coronavirus may enter China. However, considering the significant decrease in the current outbreak of human transmitted pneumonia (HPV) in the United States, as well as the fact that China has entered summer and the climate conditions are not suitable for the spread of the epidemic, it can be expected that the high incidence of HPV in the early stages of the epidemic in the United States will have limited impact on China.
Human leaning lung virus belongs to the family of pulmonary viruses, the genus of leaning lung viruses, and is a single stranded negative RNA virus with a capsule. In 2001, Dutch scholars first detected nasopharyngeal aspirates from children with respiratory infections caused by unknown pathogens. Serological studies have shown that it has existed for at least 60 years and is distributed worldwide, making it one of the common respiratory pathogens. It is mainly transmitted through coughing and sneezing, and close personal contact and touching of virus contaminated surfaces before touching the mouth, nose, or eyes may also cause transmission. Generally speaking, the incubation period after infection is about 3-5 days, and the immune protection induced by human lung viruses is weak. Repeated infections are common. Human lung viruses are detected throughout the year, with the highest detection rates in winter and spring, and can also cause outbreaks.
Children, immunocompromised individuals, and elderly individuals are susceptible to mixed infections with other respiratory viruses. It often causes symptoms of common cold, such as cough, fever, nasal congestion, and wheezing. In severe cases, it can also lead to bronchitis and pneumonia. In susceptible populations with underlying diseases, infection can lead to death. Similar to the prevention and control of other common respiratory viruses, the public should maintain a regular lifestyle and a good attitude. When going to crowded places or environments, it is best to wear masks. At the same time, preventive measures such as washing hands frequently, ventilation frequently, and scientific disinfection can effectively reduce the chance of contracting HMPV.
