Common knowledge of Coronavirus (COVID-19): What is Coronavirus?

What is a novel coronavirus?

A newly discovered coronavirus, the International Classification Committee for Viruses named SARS-Cov-2.It’s a popular coronavirus Because the population lacks immunity to the new virus strain, the population is generally susceptible. The new coronavirus is caused by SARS-Cov-2 coronavirus, which WHO name the disease caused by SARS-Cov-2 infection COVID-19, most of which can cause pneumonia.

How easily the virus spreads?

Daily face-to-face speaking, coughing, sneezing can cause droplets to spread. Some viruses are highly contagious (spread easily), like measles, while other viruses do not spread as easily. Another factor is whether the spread is sustained, spreading continually without stopping.

The virus that causes COVID-19 seems to be spreading easily and sustainably in the community (“community spread”) in some affected geographic areas.

Community spread means people have been infected with the virus in an area, including some who are not sure how or where they became infected.

COVID-19 is mainly infected with adults or larger children, causing common cold and pharyngitis, and some strains can also cause adult diarrhea. The virus is spread through droplets.Droplets can enter susceptible mucosal surfaces by a certain distance (generally 1~2 m). because the droplet particles are larger (more than 5 um), they will not be suspended in air for a long time.And the fecal pathway can also spread. Mainly popular in winter and spring. incubation period of the virus averaged 3~7 days.

If there is a suspected new type of coronavirus around the patient, remember to wear a mask. The mask should be discarded correctly after use, and the hands should be thoroughly cleaned with soap and flowing water after contact with the patient. Aerosol propagation means particles that can be airborne, generally less than 5 um, in diameter, and still infectious after long-range dispersal. airborne pathogens can also be transmitted through contact. Formerly popular SARS coronavirus, some speculated it could be airborne.

Groups at higher risk

Older adults and people of any age who have serious underlying medical conditions may be at higher risk for more serious complications from COVID-19.

How prevent new COVID-19 infection?

Prevention of new COVID-19 infections requires the following measures:

• Avoid high incidence areas
• Avoid crowded places. Avoid closed, unventilated public places and crowded places, especially children, the elderly and people with low immunity. Go out and remember to wear a mask.
• Strengthen ventilation. Every day at home to open windows ventilation for a period of time. Strengthening air circulation can effectively prevent respiratory infectious diseases.
• Pay attention to personal hygiene. Wash hands frequently. Wash hands with soap and flowing water or hands-free hand sanitizer. Cover your mouth and nose with a tissue or elbow when sneezing or coughing. Do not cover your mouth and nose with your hands.
• Observe and seek medical attention. If appear fever (especially high fever does not retreat), cough, shortness of breath and other respiratory tract infection symptoms, should wear a mask and timely medical treatment.
