By 2020, China had a whole different Chinese New Year, and that all comes from this novel coronavirus pneumonia sudden outbreak. However, many people do not quite understand for coronavirus, today small for everyone all the detailed science coronavirus.
How coronavirus infection?
To the virus enters the cell, it must have its corresponding receptor on the cell receptors as novel coronavirus and SARS, we are angiotensin-converting enzyme 2 (ACE2). This means the virus to infect humans, cells must first be exposed to this enzyme, receptor binding is completed. In a large number mucosal cells, such as our lips, eyelids, nose and mouth, corona virus, it can spread through droplets in the human memory through mucosal infection.
How coronavirus spread?
As of today, in addition to the first release of the droplets, the official also reported that the spread of aerosol transmission, fecal-oral transmission and so on.
Droplet refers to sneezing, coughing, 100 microns or particles generated droplets are evaporated rapidly in the air becomes smaller, it becomes dried droplet nuclei. Epithelial cells will be wrapped with coronavirus proteins, drifting in the air, contact with other people mucosa. Droplets generally only result in the spread of 1-2 meters at close range.
Aerosol propagation means less than 5 microns, and can survive for long periods of particles floating in the air, i.e., in the confined space, the aerosol can be formed coronavirus prolonged survival. However, this is generally spread to reach a certain amount of virus injected into the air in the form of droplets, it is easy to form an aerosol, and his survival time is about two hours.
Fecal-oral transmission is fecal contain intact virus particles, spread to humans through direct or indirect means, such as not to wash your hands after the toilet, while the hand touches the object or food, indirect intake by the body, or the stool is not reasonable emissions , leading to water pollution and other indirect ingestion of biological phenomena.
The above transmission, show that the importance of several protective measures, wear a mask and a closed environment nor the removal of masks, washing hands frequently to avoid the disease from the mouth, viral load handling ventilation to avoid the deposition. 
Since January 31, the new crown spread data pneumonia fast growth, as well as slow growth of mortality and cure rate accelerated growth, each of us can do is to respond to the call of the national epidemic prevention and control, to avoid the spread of the epidemic, not go to crowded place, good self-protection, seek immediate medical attention.
In addition, we still need to work step by step, even at home telecommuting, also need to ensure that their jobs trembling all work reasonably complete information security and content all work data, not an end of the outbreak, after the completion of the company's major discovery spotless data leakage. Therefore, radium rate the importance of the office who has become increasingly prominent, the deployment CD-speed server in the company's server, each branch point to deploy the client, simply open the web client can guarantee data security home office, in addition, file data can quickly sync, less cumbersome process, can guarantee data security.
