Novel corona-virus spreads are becoming more and more popular, and sales of city masks in Asian cities are decreasing. According to reports, China’s National Health Commission has deployed masks to medical staff responding to the outbreak and distributed millions of masks to residents of Wuhan. But can these masks stop people from getting the virus? Let us have a read about related correct understanding for N95 face masks together.


Face masks types

There are two main types of masks used to do this. One is the standard surgical mask - the kind worn by surgeons during surgery. These masks are designed to stop droplets and may reduce the risk of infection from another person. We know that corona-virus is transmitted through the air. It can spread from person to person. Researchers believe the virus may have jumped from animals to humans by inhaling particles in the air at a seafood market that sells live wildlife. So it makes sense to cover your nose and mouth.


Disposable mask

The World Health Organization recommends that all health care workers who treat virus carriers wear these surgical masks, along with gloves, goggles and pajamas. Surgical masks are considered to be a more effective clinical environment because they are accompanied by other protective equipment and strict hygiene practices. Face masks are also often replaced - surgical mouth masks are not designed to be reused once. The N95 respirator provides more protection. This N95 face mask is designed to prevent 95% of small particles from entering the nose and mouth area. However they work only when they fit, not for children or people with facial hair.


Reuse face mask

At present, masks with the function of preventing virus infection on the market are not recommended to be reused. Generally, some cold and warm masks without the function of protection can be reused. The novel corona-virus can not effectively prevent the infection of new coronavirus.


Neither N95 respirators are intended to be used more than once

The U.S. Food and Drug Administration recommends that N95 face masks and disposable masks not be shared or reused. Surgical masks and N95 respirators are designed to prevent large particles from entering the mouth. The surgical mask can not filter or block the tiny particles in the air, and can not seal the face well to provide complete protection.


Unfortunately, the best is not always what we have to face. In the medical crisis we are now experiencing, sometimes we need to make difficult decisions: in the case of disposable masks, this may mean that in any particular case, which criteria are more important to choose. CDC does have some guidance for medical staff who need to wear disposable masks or re-use face masks for a long time, which is not common in no-emergency situations. Prolonging the use time is the recommended measure to deal with the outbreak of respiratory pathogens. As long as the patient is infected with the same pathogen and placed in a specific area, medical staff can wear the same N95 respirator for several patients without taking it out. As long as the mask continues to be firmly installed, it can be worn for up to 8 hours depending on the environmental conditions. When it is hard to breathe, then it is time to change your face mask. Repeated use of mouth masks (reuse face mask) is more common without regard to contact borne pathogens and should be limited in the number of times the device is used, with great care being taken to remove, store and dispose of the respirators.


No gathering is the best

Here are other precautions that Chinese people can take to avoid infection. For example, local authorities advise residents to avoid large public gatherings. The Lunar New Year holiday has been extended in case people lose their jobs and go to school. Practicing good hand hygiene can help you.


Robin Thompson of Oxford University suggests that if you are worried about your symptoms and think you may be infected with the virus, you should call your doctor before you go to the hospital for consultation and may spread the infection.


For most people outside China who have not been to the affected area, the risk of infection is still very low. Health authorities warn against going to the affected areas, and it always makes sense to maintain good hand hygiene.
