How to Protect Yourself from COVID-19


Coronaviruses are a large family of viruses which may cause illness in animals or humans. Coronaviruses are zoonotic, meaning they are transmitted between animals and people. Usually, zoonotic diseases are harmless, but some like COVID-19 are deadly.

In humans, respiratory viruses infect the lungs and airways, thus leading to difficulties in breathing. Respiratory viruses can cause the common cold as well as more severe diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS).

The most recently discovered coronavirus is COVID-19. The first case of COVID-19 appeared in Wuhan, Hubei Province, China in December 2019.


Based on the incubation period of COVID-19, a person may be infected with the virus but may not show symptoms. After exposure to the virus, it can take between 2 to 14 days to show symptoms.

Symptoms of COVID-19 include:

  • Fever
  • Cough
  • Shortness of Breath

Certain populations are more at-risk from COVID-19:

  • Older adults
  • People with medical conditions such as diabetes, kidney, heart and lung disease
  • People who are immunocompromised


There are primarily two ways through which COVID-19 is transmitted:

Droplet Transmission: When a person coughs, sneezes or talks, tiny respiratory droplets exit his body and enter the other person’s eyes, nose or mouth.

Contact Transmission

  • Direct Contact: Touching an infected person and then touching your eyes, nose or mouth.
  • Indirect Contact: Touching a contaminated object and then touching your eyes, nose or mouth.


There are some basic preventative measures you can adopt to protect you and your loved ones from COVID-19. It is also important to adopt these measures to flatten the curve and reduce the number of individuals infected with COVID-19. This ensures that hospitals and medical staff are not overwhelmed and they are able to provide quality care efficiently.

Hand Washing: Regularly wash your hands with soap and water for 20 seconds. This is by far the best method to prevent being infected by COVID-19.

Hand Sanitizer: If soap and water is not available, clean your hands with a hand sanitizer for 20 seconds. The sanitizer must contain at least 60% alcohol. Please note that all hand sanitizers are not effective against COVID-19.

Respiratory Hygiene: It is vital to practice good respiratory hygiene. Use a tissue to cover your nose and mouth whenever you cough or sneeze. Dispose the tissue immediately, and wash your hands with soap and water. If you do not have a tissue, cough or sneeze into your bent elbow.

Social Distancing: Social distancing is crucial for stopping COVID-19. An infected person may not show symptoms. So always maintain a distance of 2 meters.

  • Avoid shaking hands.
  • Avoid touching your eyes, mouth or nose.
  • Avoid high-touch surfaces in public places like elevator buttons, door handles, etc.
  • Stay at home and limit contact with anyone outside your immediate household.
  • Cancel any social events, parties and gatherings.

Face Masks: Owing to the current shortage of face masks in the world, healthcare workers are at increased risk of contracting COVID-19. Face masks should be used only when:

  • You are a healthcare provider
  • You are sick
  • You are tending to someone sick
  • If you have been instructed by a doctor or healthcare provider to do so
