From December 2019 to early January 2020, the Spring Festival peak period of 3 billion Chinese people returned home. At this time, Wuhan outbreak of new virus is know as "new coronavirus pneumonia."
Novel Coronavirus 2019 ncov Symptoms
Coronavirus can produce a range of symptoms, including fever, cough, shortness of breath, sore throat, and runny nose. Most coronavirus infections cause only the common cold; more serious bacterial infections can cause severe pneumonia that requires hospitalization. The CDC noted that the symptoms of the new coronavirus include "symptoms of fever and lower respiratory illness (such as coughing, difficulty breathing)
How does the new coronavirus infection spread? The novel coronavirus situations in China.
During the epidemic period of the new coronavirus, the source of infection, the route of transmission, and the dynamic changes of the susceptible population are clearly identified.
① Changes in the source of new coronavirus infections: Chinese scholars have discovered that pangolin may be a potential intermediate host. The sequence of pangolin virus strains is highly similar to that of currently infected human strains, and the relationship between new human infectious diseases and other wildlife remains to be studied;
② Changes in the transmission route of new coronaviruses: We have determined that the main transmission routes of new coronaviruses are droplets and contact transmission, but the transmission of aerosols and fecal-oral routes has not been determined;
③ Changes in new coronavirus-specific treatments: Chinese scholars have successfully isolated new coronavirus strains, laying a solid foundation for the forthcoming development of new coronavirus vaccines, screening of antiviral drugs, and development of rapid detection reagents, but There may be mutations in the new coronavirus, differences in vaccination among people of different races infected with the new coronavirus ... all these changes require us to keep an eye on and respond in time.

The virus attached to the object will live for a while. Commonly used parts (door handles, handles, bed fences, etc.) are diluted with commercially available household chlorine-based bleach and wiped, and then wiped with water.
Confirm that the main component of household chlorine bleach is sodium hypochlorite bleach, and dilute the concentration according to the amount used (the reference concentration is 0.05% (for example, if the concentration of the product is 6%, add 25 ml of bleach in 3 liters of water).
Toilets or washrooms should be cleaned with regular household detergents and thoroughly disinfected with household disinfectants. Towels, clothing, tableware, chopsticks, spoons, etc. can be washed in general. Utensils used by infected persons do not need to be washed separately.
