On January 10, a woman returned to Anyang from Wuhan and five of her relatives were diagnosed with pneumonia from a novel coronavirus infection. None of the five patients had a history of residence or travel in Wuhan, and all were diagnosed with the virus after coming into contact with the woman. The woman, however, was asymptomatic. The National Health Commission said early in the press conference – asymptomatic infected persons can also transmit the virus. What is an asymptomatic infected person? Asymptomatic infected persons are: a category of patients with new coronary pneumonia who do not have obvious clinical manifestations such as fever, malaise, or pneumonia, but who test positive for viral nucleic acid. A case like the one in the news of appeal, which itself showed no symptoms, is an asymptomatic infected person. An asymptomatic infected person can be described as either not serious or serious. Not serious means, in fact, that most diseases caused by viruses can present asymptomatic infected persons. The World Health Organization also believes that transmission of other coronaviruses through asymptomatic patients is very rare. Therefore asymptomatic patients may not be the primary transmitters of the virus. In fact, asymptomatic infected patients carry a relatively small amount of virus and have no cough symptoms, and there are fewer cases of forming large aerosols carrying the virus as long as they wear a good mask. Therefore, although asymptomatic infected persons can transmit the virus, the percentage is very low. However, asymptomatic infected people can be a big problem! Some people worry that they are in good health now, but could they be an asymptomatic infected person? What if they are not aware of the situation and become the “king of the virus” as a potential source of infection? But from the known situation, Zhong Nanshan academician said in an interview with CCTV News on February 2: First, the vast majority of asymptomatic infected people have contact with confirmed patients, or have a history of contact with Wuhan before they go for testing. In other words, there is no need to suspect that you are asymptomatic infected if you have not been to Wuhan and surrounding areas, and there are no family clustering cases around you, and no close contact with suspected or confirmed cases. However, if you do, you should promptly report to the community or the CDC to reflect the situation, take protective measures and go to the fever clinic for medical examination. What should we do when faced with an asymptomatic infected person? There is no need to be overly alarmed, as long as you take basic precautions. Asymptomatic infections can’t hurt you! 1. Wear a mask, wash your hands regularly, disinfect regularly and ventilate regularly. When all people do these four independent protection, it is enough to prevent and control the threat of asymptomatic infections. Do not underestimate any of these protective measures. When you touch the same place as an asymptomatic infected person in your daily life, you can become a new latent transmitter of the virus. Therefore, always stay alert, not only to protect yourself, but also to protect your family and friends. 2. Keep a meter distance and avoid items in common. We all know that the transmission of New Coronary Pneumonia is mainly through respiratory droplet transmission, but also through contact transmission. Wear a good mask, keep a distance of 1 to 2 meters, avoid sharing some items (such as resumption of work partners to avoid and colleagues common office utensils), but also can play a good protective effect. 3, in fact, at present, most cities have taken the Wuhan return staff isolation measures for 14 days, the spread of asymptomatic patients will also be to some control. There is no need to be overly alarmed and ensure that you are in a comfortable mood. Finally, if you suspect that you are infected, or have developed some symptoms of infection with the new coronavirus, you must report the isolation in a timely manner. Everyone should do their own protection to isolate the spread of the virus, and with strict prevention and control, we can gradually reduce the emergence of the next generation of virus transmitters.
