Mask to protect from Coronavirus
1. Wearing of the mask will contain the spread of the virus.
2. Type N95 mask creates a barrier preventing respiratory droplet from travelling in the air. When someone coughs, sneezes, or talks mask to reduce the spray of the droplet when worn over the nose and mouth. When worn properly, only 5% of particles 0.1 microns in size can penetrate these masks.
3. 3M medical respirators protect the wearer from getting sick and protect the patient from the wearer’s germs. However, 'No respirator will eliminate exposure to the virus.'
4. Approximately 40% to 45% of people with COVID-19 are asymptomatic and they can transmit the virus to others for an extended period, possibly longer than the typical 14 days – those people are unaware they have the disease. Without wearing a mask, they may unknowingly spread it to others, by talking!
5. When others wear a mask, they help protect you. When you wear a mask, you help protect others.
6. Wearing a mask and being able to go outside is a better choice than to stay inside until the pandemic is over.
1. Can restrict airflow, cause skin irritation, be uncomfortable, cause glasses to fog and many people end up touching their face absentmindedly because viruses accumulate on the surface of the masks.
2. Coronavirus can remain infectious on soft surfaces like masks for many hours, so the wearer must be very careful when removing the mask: Touching an infected portion of the mask could transmit the virus.
3. It is important to use both disposable and reusable masks properly. If a virus or other health-threatening microorganism is left on a disposable mask, touched, and then hands are not washed, an infection may occur.
4. Wash the washable kind at the end of the day or after extended use. (6-8 hours)
5. How about blue surgical masks? They should be thrown away when it is visibly soiled or damaged.
