The new coronavirus is called Novel Coronavirus (2019-nCoV) and was named by the World Health Organization in 2020. First discovered in 2019, the new coronavirus is heat sensitive and can be inactivated by temperatures of 56 degrees and above. In addition, 75% ethanol, chlorine-based disinfectants, and peracetic acid can kill the new coronavirus. People infected with the novel coronavirus will mainly cause novel coronavirus pneumonia. People infected with the virus may suffer from fever, cough, difficulty in breathing and other uncomfortable symptoms, which may lead to death in severe cases. The new coronavirus is mainly transmitted through respiratory droplets and is highly contagious. At present, there is no effective clinical treatment of new coronary drugs, only symptomatic treatment. People should pay attention to personal hygiene in daily life, wash hands and disinfect frequently, and avoid going to places where people gather. If you feel unwell, you should seek medical treatment immediately.
