Novel coronavirus infection is generally possible when the distance of transmission is less than 1 m. Beyond 1 m, the chance of contracting a novel coronavirus is relatively small. The closer the distance, the greater the chance of infection, and the farther the distance, the lower the chance of infection. When you go out, keep a distance of more than 1 meter between people to reduce the chance of contracting novel coronavirus. Novel coronaviruses are a group of inflammatory changes in the lungs caused by infection with a novel genus of beta coronavirus. The virus is sensitive to ultraviolet light and heat. Novel coronaviruses are transmitted primarily by respiratory droplets, but can also be transmitted by close contact. Respiratory droplet transmission is usually at a distance of about 1 meter. Clinical manifestations of novel coronavirus include fever, malaise, dry cough, and in a few patients, nasal congestion, runny nose, and diarrhea. The main source of infection seen is patients with pneumonia infected by the novel coronavirus, and the population is generally susceptible to infection. Pharyngeal swab specimens can be collected for nucleic acid testing for novel coronaviruses. In addition to keeping a distance from novel coronavirus infections, wearing a mask can also reduce the chance of novel coronavirus infection. Try to avoid going to high risk areas in the outbreak.
