FACT: The prolonged use of medical masks when properly worn, DOES NOT cause CO2 intoxication nor oxygen deficiency
The prolonged use of medical masks can be uncomfortable. However, it does not lead to CO2 intoxication or oxygen deficiency. While wearing a medical mask, make sure it fits properly and that it is no so tight that it prevents you from breathing normally. Do not re-use a disposable mask and always change it as soon as it gets damp.

FACT: Ultra-violet (UV) lamps should NOT be used to disinfect hands or other areas of your skin
UV radiation can cause skin irritation and damage your eyes. Cleaning your hands with alcohol-based hand rub or washing your hands with soap and water are the most effective ways to remove the virus.
FACT: Hand dryers are NOT effective in killing the COVID-19 virus
Hand dryers are not effective in killing the COVID-19 virus. To protect yourself, frequently clean your hands with an alcohol-based hand rub or wash them with soap and water. Once your hands are cleaned, you should dry them thoroughly by using paper towels or a warm air dryer.
FACT: The COVID-19 virus can spread in hot and humid climates
The best way to protect yourself against COVID-19 is by maintaining physical distance of at least 1 metеr from others and frequently cleaning your hands. By doing this you eliminate viruses that may be on your hands and avoid infection that could occur by then touching your eyes, mouth, and nose.
FACT: Cold weather and snow CANNOT kill the COVID-19 virus
There is no reason to believe that cold weather can kill the new coronavirus or other diseases. The normal human body temperature remains around 36.5°C to 37°C, regardless of the external temperature or weather. The most effective way to protect yourself against the new coronavirus is by frequently cleaning your hands with an alcohol-based hand rub or washing them with soap and water.
FACT: Thermal scanners CANNOT detect COVID-19
Thermal scanners are effective in detecting people who have a fever (i.e. have a higher than normal body temperature). They cannot detect people who are infected with COVID-19.
There are many causes of fever. Call your healthcare provider if you need assistance or seek immediate medical care if you have fever and live in an area with malaria or dengue.
