A coronavirus is a virus group, belonging to betacoronavirus family responsible for causing a range of respiratory diseases, from common cold, influenza to more severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS). Recently, a new addition to this family has been found out which is responsible for the global outbreak of a potentially fatal disease, COVID 19. The virus is named as SARS-CoV-2 or the severe acute respiratory syndrome coronavirus 2, while the resulting disease is referred to as COVID 19 or coronavirus disease 2019. The COVID 19 was declared a global pandemic in March 2019 owing to its rapid spread in over 250 countries, globally.
Symptoms of COVID 19
Signs and symptoms of COVID 19 may emerge in 2 to 14 days in the patient after getting exposed to the virus. They can range from very mild to fatal and may include:
- Difficulty in breathing, called dyspnoea
- Fatigue or Tiredness
- Body or Joint Pain
- Constantly running nose
- Sore Throat
- Diarrhea and vomiting have also been reported in a minor group of patients

Elderly patients, patients with impaired immunity such as HIV/AIDS or those suffering from co-morbid conditions such as diabetes, heart or lung diseases are at elevated risk of fatal outcomes from COVID 19.
Causes of COVID 19
COVID 19 is caused by the SARS-CoV-2 virus as it spreads to persons in close contact with an already infected patient through the respiratory droplets, by coughing or sneezing. It can also spread by touching the surface containing the virus and then touching your mouth, nose or eyes with the same part.
