Can facemask n95 prevents us from coronavirus?

Coronavirus is spreading across the globe at this time demand for facemask n95 increased rapidly to cope with the infection of coronavirus.

In this situation, the biggest question arises that

Can Facemask prevent us from coronavirus?

The answer to this question is NO If it's a regular surgical face mask. but if we are n95 respirator it is really effective against coronavirus.

regular medical face masks aren't as effective at protecting from coronavirus as most people think, doctors and scientists say.

That's because regular face masks block only large particles and droplets, not small virus particles, and they're typically loose-fitting.

as TIME says
Local government officials in Wuhan have required that people wear face masks when they go out in public places to prevent the spread of infection.


Retailers across the Internet are running out of antiviral face masks as the number of confirmed cases of the coronavirus (2019-nCoV) now exceeds 9,700 globally.

More than 200 people have died from the virus in China, where the majority of the 2019-nCoV cases have been detected. The World Health Organization declared a global health emergency on Thursday as the outbreak continues to spread.

A specialized mask, known as an N95 respirator, can protect against the new coronavirus, also called 2019-nCoV. The respirator is thicker than a surgical mask, but doctors don't recommend it for public use, at least not at this point.

Specialists who attend infectious disease on a regular basis are trained very well how to properly fit these respirators around the nose, cheeks, and chin, ensuring that wearers don't breathe around the edges of the respirator. "When you do that, it turns out that the work of breathing, since you're going through very thick material, is harder. You have to work to breathe in and out.

Surgical masks


  • This the kind wore by surgeons during operations.

  • Protect the wearer against large droplets or splashes of bodily and infected fluids from others.

  • Do not prevent a person from inhaling smaller airborne particles.

  •  A facemask is a loose-fitting, disposable device that creates a physical barrier between the mouth and nose of the wearer and potential contaminants in the immediate environment.

Respirators N95


It designed to prevent most small particles from entering the nose and mouth area it is effective up 95%.

Recommended for healthcare professionals treating patients infected by coronavirus (nCoV).

It can make it more difficult for a person to breathe.

Only work if they fit properly and aren't suitable for children or people with facial hair.

The masks made available are the N95 respirator type, which prevents 95% of small particles, including pathogens from entering the nose and mouth.

What is the meaning of N in N95?


Particulate respirators and cartridges are classified by NIOSH into three classifications, N, R, and P.

• N class respirators/cartridges are not resistant to oil mists.
  • R class respirators/cartridges are resistant to oil mists (<8 hours).
  • P class respirators/cartridges are oil-proof (>8 hours).

What does the 95 in N95 stand for?


95 refers to the efficiency of the filtration of the respirator or cartridge, meaning it filters at least 95% of 0.3 micrometers, meaning it has a 5% leakage factor.

There are two types of N95 respirators the question is which one should we choose.

  • Surgical N95 respirators
  • The surgical N95 respirators give you the protection of both an N95 respirator and a surgical or procedure mask.

  • Industrial or non-medical respirators
  • Most N95 respirators available at the local hardware store or pharmacy have been certified by NIOSH to filter the air you breathe. However, they do not have the additional protection of a surgical mask.

N95 respirators are disposable and cannot be cleaned.

What are the limitations of the N95 mask?


Some limitations of an N95 respirator include
  • N95 respirator does not fit children and cannot be adapted to properly fit a child and the child may feel breathing problems.

  • Beards, stubble or long mustaches may prevent an N95 from sealing to the face properly, causing leaks.

  • It may be difficult for first-time users to put an N95 respirator on properly practice putting it on before an emergency arises.

  •  N95 respirators may make breathing more difficult and lead to increased breathing and heart rates. Individuals with heart and respiratory conditions should check with their doctor before wearing an N95 respirator.

  • N95 respirators should be worn for a maximum of eight hours and should be replaced regularly. 

  • N95 respirators do not provide oxygen so they should never be worn in a confined space with low oxygen levels.

  • N95 respirators do not affect an atmosphere containing toxic levels of gases or vapors.

Is there a vaccine for the coronavirus?

There are many coronaviruses. Vaccines are available for some of them. The coronavirus that first emerged in humans in December 2019 was previously unknown.

The virus has been given a name, 2019-nCoV, but the disease it causes in humans has not been named yet.

This is to say that as of January 25, 2020, it is simply too early for there to be a vaccine for this disease because for developing a vaccine it takes several tests in several conditions and is done for every age group, and in all this process it takes a lot of time because

  • Short term effects on the body (either good or bad)
  • long term effects on the body (either good or bad)

these all things are taken into consideration. After all the testing, analyzing data and statistics a vaccine is supplied for the use.

Studies of SARS and another coronavirus disease, MERS, and several animal diseases caused by coronaviruses have led to enough understanding of these viruses that there may be useful shortcuts to developing a vaccine.

In the past couple of decades, tools to decode and modify DNA have advanced far enough that developing a vaccine for the new coronavirus disease in less than a year isn't unimaginable. It might even be possible to test the safety and effectiveness of a new vaccine and begin to produce and distribute it before two years have passed.

GMO techniques can help us in creating a vaccine against the nCoV. This is a good thing. Genetic modification is a powerful tool that can be used to produce extremely useful things for humans as well as other animals.

Should I be tested for 2019-nCoV?

If you develop these things like
  • Fever
  • symptoms of respiratory illness
  • cough
  • shortness of breath

within 14 days after travel from China, you should call ahead to a healthcare professional and mention your recent travel or close contact. If you have had close contact with someone showing these symptoms who has recently traveled from this area, you should call ahead to a healthcare professional and mention your close contact and their recent travel. Your healthcare professional will work with your state’s public health department and CDC to determine if you need to be tested for 2019-nCoV.


How do you test a person for 2019-nCoV?


At this time, diagnostic testing for 2019-nCoV can be conducted only at CDC.
State and local health departments who have identified a person under investigation (PUI) should immediately notify CDC’s Emergency Operations Center (EOC) to report the PUI and determine whether testing for 2019-nCoV at CDC is indicated. The EOC will assist local/state health departments to collect, store, and ship specimens appropriately to CDC, including during after-hours or on weekends/holidays.
For more information on the specimen collection see CDC Information for Laboratories.


Can a person test negative and later test positive for 2019-nCoV?


Using the CDC-developed a diagnostic test, a negative result means that 2019-nCoV was not found in the person’s sample. In the early stages of infection, it is possible the virus will not be detected.

For 2019-nCoV, a negative test result for a sample collected while a person has symptoms likely means that 2019-nCoV is not causing the
