New type of coronavirus pneumonia is in the early rapid change stage. China has published the entire genome sequence of a new coronavirus that causes new coronavirus pneumonia, which will help global scientists and public health organizations to join in the development of diagnostic reagents and virus pathogenicity research.
The National Health Commission of China has issued Announcement No. 1 to include pneumonitis infected with the new coronavirus as a Class B infectious disease under the Law on Infectious Diseases Prevention and Control. .
On January 12, 2020, the World Health Organization officially named the new coronavirus that caused the Wuhan pneumonia epidemic as 2019-nCoV (2019 new coronavirus), where 2019 represents the earliest year of occurrence, n represents Novel (new), and Cov represents Coronavirus.
Some coronaviruses can be transmitted not only from animals to humans but also from humans to humans. For example, SARS is passed from human to civet, and MERS (Middle Eastern Respiratory Syndrome) is passed from human to dromedary camel. Academician Zhong Nanshan said on January 20 that according to the current data, the new type of coronavirus pneumonia is a sure human-to-human transmission, and 14 medical staff in Wuhan were infected during the care of one patient.
The clinical manifestations of patients with pneumonitis infected by the new coronavirus are: fever, fatigue, and dry cough. Nasal congestion and runny nose are rare. About one-half of the patients develop dyspnea after one week. In severe cases, they progress rapidly to acute respiratory distress syndrome, septic shock, difficult to correct metabolic acidosis, and coagulation dysfunction. It is worth noting that in the course of severe and critically ill patients, there can be moderate to low fever, even without obvious fever. Some patients have mild onset symptoms and no fever. They usually recover after 1 week. Most patients have a good prognosis, and a few patients are critically ill and even die.
How to prevent
Wash your hands frequently. If you do not wash your hands, use alcohol-based hand sanitizer.
Based on the current epidemic situation, try not to go to Wuhan (recommended by members of the high-level expert group of the National Health Commission of China on January 20) and recommend wearing a mask in a crowded public place.
If you go to Wuhan during this time, avoid contact with animals (whether live or dead), animal markets, and animal products (such as raw meat).
Finally, we pray that the infectious disease in Wuhan, China will end soon. Come on Wuhan, come on China!
