Precautions to be taken to prevent Covid-19:
1. Wash your hands: Keep your hands clean and wash them regularly with soap and water for at least 20 seconds or use hand sanitizer that contains at least 60% alcohol. Do not touch your mouth, nose or eyes with unwashed hands as it can lead to direct inhalation of virus into the body.
2. Use Mask: Cover your mouth and nose with mask when stepping out of your home as it prevents the direct spread of virus from one to another.
Masks should not be worn by the following:
1. Wash your hands: Keep your hands clean and wash them regularly with soap and water for at least 20a. Children younger than 2 years old.
b. Anyone who has trouble breathing.
c. Anyone who is unconscious, incapacitated, or otherwise unable to remove the mask without assistance.
3. Social Distancing: Keep at least 6 feet of distance between yourself and others while you are outside of your home. This is important as it reduces the chances of one catching virus from another.
4. Cover coughs and sneezes: Always cover your mouth and nose with tissue while coughing or sneezing or use the inside of your elbow. Do not spit publicly and throw the used tissue into the trash bin immediately. Afterwards, immediately wash your hands with soap and water for at least 20 seconds or use hand sanitizer to prevent inhalation of virus.
5. Clean and disinfect: Regularly touched surfaces should be cleaned and disinfected regularly as to avoid accumulation of dirt and to reduce the risk of virus.
