The 2019 novel coronavirus (SARS-CoV-2) is a new strain of coronavirus found in humans in 2019. Symptoms of the virus are generally fever, fatigue, dry cough, progressive dyspnea, and in severe cases, acute respiratory distress syndrome, septic shock, metabolic acidosis that is difficult to correct, and coagulation dysfunction. The virus has been confirmed to have human-to-human transmission, and the incubation period is contagious, and there is no specific treatment for the disease. The main transmission routes of the new coronavirus are still respiratory droplet transmission and contact transmission, and the transmission routes such as aerosol and fecal-oral transmission remain to be further clarified. Epidemiological investigations show that most cases can be traced to close contacts with confirmed cases. There are two ways to detect the new coronavirus: 1. Through nucleic acid detection (https://elisakitgs.com/product/ccovid-19-nucleic-acid-detection-kit), through the patient's respiratory secretions and blood for detection, It has a high success rate, but there are also false negatives. 2. The detection by chest CT can be seen in the patient's condition changes, and serious changes such as white lung appear in the lungs, which can be displayed in the form of CT, and its diagnosis rate very high.
