COVID-19 is an infectious disease that is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

On December 31, 2019, the World Health Organization (WHO) was informed of several cases of viral pneumonia of unknown cause detected in Wuhan City, China. The outbreak quickly evolved, affecting other parts of China and many countries around the globe. The first mystery disease was first called 2019-Novel Coronavirus or NCOV, and later on became Coronavirus Disease or COVID-19.

The new coronavirus spreads through droplets from an infected person who coughs or sneezes. People of all ages, both female and male, can be infected by this virus. People having pre-existing diseases like asthma, heart diseases and diabetes appear to be the most vulnerable to becoming severely ill.

Patients Under Investigation (PUI) and Persons Under Monitoring (PUM) are the two terms that are often used whenever COVID 19 is reported. People who have a history of travel from outside the country within 14 days before they feel the symptoms, having close contact with the person having symptoms and a member of a positive cluster of patients are called Patient Under Investigation (PUI). On the other hand, a person is considered as a Person Under Monitoring when he/she is not showing any symptoms related to the disease but has a travel history and a history of exposure to the novel virus.


With this disease, patients mostly suffer from the following:

  • Fever
  • Cough
  • Shortness of breath
  • Sore throat
  • Runny nose
  • Body aches

Some symptoms are called emergency warning signs for COVID 19 in which you need medical attention immediately. These signs are:

  • Having trouble breathing
  • Persistent pain
  • Inability to be roused
  • Bluish lips or face

These symptoms may occur 2-14 days after initial exposure to someone who is infected or to the virus itself. Some people show no signs in the early phase but can still infect others. In this case, home care self-quarantine is a must.


If a patient shows signs and symptoms of COVID-19, immediately contact your doctor.

Tell your doctor important information like travelling to areas that are affected and having close contact with someone infected. These factors may be used to test you for COVID-19.

Polymerase chain reaction (PCR) testing is the primary COVID-19 diagnostic testing. This test collects the following:

  • Swab in the nose and throat
  • Aspirate fluid
  • Saliva or stool samples


As of today, there is no accurate medicine yet that is recommended to treat COVID-19, but healthcare providers may give the following to help relieve symptoms:

  • Pain relievers
  • Medicines for cough
  • Advise rest
  • Advise intake of fluid

If you think you have COVID-19 follow the DO’S and DON’TS and these are the following:


  • Stay home except if you need to go to the doctor
  • Home isolation
  • Get in touch with your doctor
  • Wear a mask
  • Cover when you cough or sneeze
  • Often wash your hands
  • Disinfect your things
  • Monitor your symptoms
  • Go to the doctor when needed


  • Going outside the house
  • Sharing household items
  • Rubbing your eyes, nose, and face
  • Panicking
