It has been nearly three years since the New Coronavirus outbreak, and in that time, our work, lives and way of thinking have changed dramatically.
To date, a total of 5,846,327 patients have been diagnosed, 318,791 have been cured, and 24,740 have died, and the numbers are still increasing!
Get to know New Crown first
Novel coronaviruses belong to the beta genus of coronaviruses with an envelope and round or oval particles, often polymorphic, 60-14 in diameter.
The new coronavirus belongs to the same coronavirus as SARSr-CoV and MERSr-CoV, which are parallel to SARS coronavirus, and they are the same class (virus), but not the same kind.
Transmission routes of the new coronavirus.
Direct transmission: also known as droplet transmission, infection can be caused by direct inhalation of droplets from patients sneezing, coughing, talking, and exhaled gases when in close contact with others.
Close contact transmission: Close physical contact occurs while living, working and studying with a person infected with the new coronavirus, or while using an object together.
Aerosol transmission: Droplets containing the new coronavirus in a closed environment are mixed in the air to form an aerosol that can cause infection when inhaled by susceptible people.
A small question about the new crown, together to understand
--Can simple skin-to-skin contact transmit the virus?
Simple skin-to-skin contact such as shaking hands, for example, does not cause transmission of the new coronavirus, provided, of course, that both parties are careful about hand hygiene and that there are no skin lesions.
Contact transmission means that the virus comes into direct contact with the mucous membranes of the eyes, nose, and mouth, which are much different from the skin.
--Can receiving takeaways and deliveries from others spread viruses?
Generally speaking, the likelihood is not very high, but protection is still needed.
When taking out and courier definitely bring a good mask, do a good job of basic protection, after taking it is recommended to disinfect the outer packaging with 75% alcohol spray.
When will the new crown epidemic end? Huang Jianping's team, a member of the Chinese Academy of Sciences, makes a prediction
The article on "Will the Omicron pandemic come to an end" published by the team of academician Jianping Huang of Lanzhou University in the English journal Innovation, published by the Young Innovation Promotion Association of the Chinese Academy of Sciences in collaboration with Cell Press, is showing that the new crown pandemic will come to an end around November 2023.
A team of expert members from multiple fields, including Academician Huang Jianping of the Chinese Academy of Sciences, has used the self-researched New Crown Pneumonia Epidemic Prediction System to predict the emergence of epidemics in China several times, with an accuracy rate of 94% of the results.
But about when the epidemic will end, or whether the virus will mutate, whether there will be a more powerful virus in the future, in addition, although our country has done a good job of prevention and control measures for the epidemic, but the country has not yet closed its doors, so that people should be alert to foreign imports
The predictions made by Academician Huang Jianping are only for the current state of the epidemic, and new adjustments will be made in the future if there are new changes in the virus!
Knowledge expansion: How contagious is the new coronavirus?
Some time ago, The Lancet published a result from a team of researchers at the University of Hong Kong that concluded that the RO (basic number of infections) of the new coronavirus is 2.68 in the baseline situation, which means that one patient or carrier of the virus can infect an average of 2.68 people.
In general, the current study concluded that the basic infectious number of all new coronaviruses is between 1.5 and 3, which is smaller than the 3.1-4.2 of SARS virus.
Is the mortality rate of neocoronavirus high?
A retrospective research article published in the international medical journal The Lancet suggests that neocoronavirus infection is more likely to affect older men with comorbidities and that, in addition, older age, obesity and comorbidities may be associated with increased mortality.
Although no definitive conclusion can be made about the mortality rate, it is generally accepted in the academic community that the mortality rate of this virus is significantly lower than that of two other coronaviruses: MERS, which has a one-third mortality rate, and SARS, which has a mortality rate of about one-tenth.
How can individuals prevent being infected by the virus?
Pay attention to sneezing etiquette; in a swift 0.34 seconds, saliva has already spread 70 cm away. Therefore, sneezing should be done with a thicker tissue or by covering your mouth and nose with a cuff.
Wear ordinary medical masks to go out, the vast majority of droplet nuclei with ordinary medical masks is sufficient, no need to wear N95.
Wash your hands often and for a long time, it takes at least 20 seconds to scrub your hands with foam, which is the equivalent of singing the "Happy Birthday to You" song twice as long.
Conclusion: Today, the new coronavirus has not been completely eradicated, we still need to strengthen prevention and control, during the epidemic, it is critical to do self-protection measures.
