What is the difference between medical masks and respirators whiel combatting COVID-19?

See full answerMedical masks (also known as surgical masks) are:• composed of 3 layers of synthetic nonwoven materials• configured to have filtration layers sandwiched in the middle• available in different thicknesses• have various levels of fluid-resistance and filtrationRespirators (also known as filtering facepiece respirators – FFP) are available at different performance levels such as FFP2, FFP3, N95, N99.Medical masks and respirator masks are similar in their protection value. However, respirators are specific for certain procedures and instances because they have a tightly fitted component to them. Respirator masks are designed to protect healthcare workers who provide care to COVID-19 patients in settings and areas where aerosol generating procedures are undertaken. Healthcare workers should be fit tested before using a respirator to ensure that they are wearing the correct size.

Does WHO recommend the use of masks with exhalation valves to prevent transmission of COVID-19?

No, WHO does not advise using masks or respirators with exhalation valves. These masks are intended for industrial workers to prevent dust and particles from being breathed in as the valve closes on inhale. However, the valve opens on exhale, making it easier to breathe but also allowing any virus to pass through the valve opening. This makes the mask ineffective at preventing the spread of COVID-19 or any other respiratory virus.

What is the incubation period of the coronavirus disease?


What does airborne transmission of COVID-19 mean?

See full answerAirborne transmission is defined as the spread of an infectious agent caused by the dissemination of droplet nuclei (aerosols) that remain infectious when suspended in air over long distances and time. (11) Airborne transmission of SARS-CoV-2 can occur during medical procedures that generate aerosols (“aerosol generating procedures”).(12) WHO, together with the scientific community, has been actively discussing and evaluating whether SARS-CoV-2 may also spread through aerosols in the absence of aerosol generating procedures, particularly in indoor settings with poor ventilation.

The child should be isolated, and medical advice sought as soon as they start to feel unwell, even if symptoms are mild.Family members/caregivers who come within 1 metre of the sick child at home should also wear a mask. A household member who is sick or has tested positive with the virus that causes COVID-19 should be isolated from everyone else if possible. If the child comes within 1 metre of the sick person at home, the adult and child should wear a medical mask during that time.

How can ventilation reduce the risk of contracting COVID-19 in airplanes?

Most airplanes have cabin air filtration systems equipped with HEPA filters which can remove viruses and germs quickly, minimizing how long people are exposed to any potential infectious virus or bacteria expelled by a cough or sneeze.
