Wearing surgical masks like disposable face masks is synonymous with acute care and is so deeply ingrained that you may not have heard it until recently. However, some practices have abandoned the use of masks in recent decades, such as healing wounds. The use and retrieval of surgical face masks was performed in an ad hoc manner that was inconsistent with evidence-based practice.

When should I wear a mask?

When there is a foggy period
According to the Ministry of Health's frequently asked questions about the Hays Health Advisory, healthy people who need to be outside for hours should wear masks to reduce exposure if the expected air quality is within a dangerous range (PSI> 300 ) May be If the expected air quality is very unusual (PSI> 200), vulnerable people are encouraged to avoid or minimize outdoor activity. If you need to be outside for a few hours, wearing an N95 mask can reduce exposure. Seniors, pregnant women, and women who have severe lung or heart problems with dyspnea at rest or while exercising should talk to their doctor about using an N95 mask.

The N95 mask is not required for short exposures, such as traveling from home to school or work, or traveling from a bus stop to a shopping center. N95 masks are not required indoors.

Wearing a surgical mask is one way to prevent bacteria from spreading to others if you don't feel well. Worn masks prevent water droplets from entering the air when coughing or sneezing.

Face masks provide additional protection against disease. However, the CDCTrusted source recommends wearing a mask only when directed by an expert or when you have symptoms of a respiratory illness, including COVID-19, to protect people around you from infection. .

Wash your hands often, especially if you are around other people who may be sick. Also, get an annual flu shot to keep you and others from spreading the virus.
