It also prevents the spread of infectious respiratory secretions such as sneezing, cough from others. The top of the mask contains a metal strip that can be formed to your nose. In China, the government has told of his citizens to wear disposable masks. American health authority announces that the mask is not effective against the spread of coronavirus. But science says that Masks protect healthcare workers from the spread of high levels of the viral pathogen. The coronavirus spreads through the diffusion of millions of tiny viral particles from someone coughs, sneezing, etc. Viral particles can gain access to enter our body through mouth, nose or eyes, etc. So almost every version of manufacture masks has at least a level of protection. Masks can work at home as well. The World Health Organization (WHO) and Disease Control and Prevention (CDC) both were advice the people to wear the mask. In 2009 CDC studies shows that mask could cut caretakers' risk of viral infection by 60-80%. But without using hand sanitizer mask may not much protectable from virus report from the University of Michigan during 2007-2008.
Standard surgical mask

Standard surgical masks shield in opposition to contact transmission with illnesses including coronavirus. It also shield in opposition to large droplets, splashes that can cause illness.

However testing via the fitness and safety executive observed that once a sneeze landed on them traces were found interior of this mask.

The report on stopping the spread of swine flu says: 'they need to no longer be used in situations where close publicity to infectious aerosols [sneezes and coughs] is probable. This degree of safety may not sufficiently lessen the likelihood of transmission via this direction'. Report from dailymail.

N95 respirator mask
An N95 respirator is a more tight-fitting mask can filter out 95 percent of particles including virus and bacteria. It is circular or oval shape and is designed to form a tight seal to your face. Some types have an attachment called an exhalation valve, which can help with breathing and the buildup of heat and humidity. But you should fit the N95 in your face otherwise it is lost its effectiveness.

Homemade face masks
On the urgent response and shortage of surgical masks, many local people have begun making their masks from various materials such as scarfs and pillowcases.
One study showed that homemade masks are maybe half as effective as surgical masks and 50 times less effective than N95 masks.
Another study showed that surgical masks are three times better in a bacterial filtration test and twice as well at blocking droplets in a cough test compare to homemade masks. So disposable masks may better wear for protection against the spread of coronavirus. But the local ingredients using homemade masks sometimes dangerous due to using poor quality ingredients.
