How to reduce the risk of infection from Virus?
Recent advances have been made in the identification of unexplained viral pneumonia pathogens in Wuhan, and preliminary identification is a new type of coronavirus. SARS in 2002 and Middle East respiratory syndrome in 2012 were also caused by coronavirus infections. What is a coronavirus and how is it different from SARS and Middle East respiratory syndrome caused by coronaviruses, and how should ordinary people prevent it?
What is a coronavirus?
The China CDC WeChat public account "China CDC Dynamics" released an article on the 9th stating that coronavirus belongs to the genus Trotaviridae, coronaviridae, and coronavirus, and is a large class of viruses widely existing in nature. Coronavirus only infects vertebrates, and is related to a variety of diseases in humans and animals, which can cause respiratory and digestive tract and nervous system diseases in humans and animals.
According to reports, there are currently six known human coronaviruses. Four of these coronaviruses are more common in the population and are less pathogenic, generally causing only minor respiratory symptoms similar to the common cold. The other two coronaviruses°™Severe Acute Respiratory Syndrome Coronavirus and Middle East Respiratory Syndrome Coronavirus, also known as SARS Coronavirus and MERS Coronavirus, can cause severe respiratory diseases. The new coronavirus that caused the outbreak is different from the human coronaviruses that have been discovered, and further understanding of the virus requires further scientific research.
What's different about new coronaviruses?
Liu Youning, director of the Institute of Respiratory Diseases of the PLA General Hospital, said that there are many types of coronaviruses, including severe acute respiratory syndrome coronavirus (SARS coronavirus) and Middle East respiratory syndrome coronavirus (MERS coronavirus). The clinical manifestations of Wuhan pneumonia show that this new coronavirus is far less severe than SARS and MERS.
How can ordinary people prevent it?
According to "China Disease Control Trends", human coronavirus is more sensitive to heat. As the temperature rises, the resistance of the virus decreases. For example, HCoV-229E can lose its infection at 56 °„ C for 10 minutes or 37 °„ C for several hours. Sexually, SARS-CoV can survive for 4 days at 37 °„ C. Heating at 56 °„ C for 90 minutes and heating at 75 °„ C for 30 minutes can inactivate the virus. Human coronavirus is sensitive to organic solvents and disinfectants. 75% alcohol, ether, chloroform, formaldehyde, chlorine-containing disinfectants, peracetic acid and ultraviolet rays can inactivate the virus.
Professor Lu Hongzhou, secretary of the Party Committee of Shanghai Public Health Clinical Center affiliated to Fudan University, pointed out that coronavirus infections are very common worldwide and the public need not panic. To prevent viral pneumonia, we must enhance our awareness of health and health, usually strengthen exercise, work regularly, and improve our immunity. In addition, even in cold weather, you should pay attention to the ventilation of the room and office. Ventilation can reduce the number of viruses in the air, thereby reducing infection. Family or office colleagues became ill during the epidemic season. Others should pay attention to isolation to reduce the chance of transmission. During the viral pneumonia and influenza season, try to get as few crowded places as possible. In addition, after going home by public transportation such as subways and buses, you must change your jacket, wash your hands, and wash your nose.
It should be reminded that the entire population is generally susceptible to influenza, and drug prevention cannot replace vaccination. Influenza vaccination is the most effective way to prevent influenza virus infection and its serious complications
