COVID -19 brings the world to a standstill

8 April 2020

COVID -19 is a new strain ,discovered in 2019 and has never been previously identified in humans.

The Covid-19 virus is humanity’s newest foe, with the potential to prematurely end millions of lives. Its fast and wide spreading nature has qualified it to be assigned the term of a pandemic.


  • COVID-19 is a disease caused by the “novel corona virus”.
  • Common symptoms are:  Fever  Dry cough  Breathing difficulty  Some patients also have aches and pains, nasal congestion, runny nose, sore throat or diarrhoea .
  • About 80% of confirmed cases recover from the disease without any serious complications.
  • However, one out of every six people who gets COVID-19 can become seriously ill* and develop difficulty in breathing.
  • In more severe cases, infection can cause severe pneumonia and other complications which can be treated only at higher level facilities (District Hospitals and above).
  •  How does COVID-19 spread?  
  • COVID-19 spreads mainly by droplets produced as a result of coughing or sneezing of a COVID-19 infected person.
  • This can happen in two ways:
  • Direct close contact: one can get the infection by being in close contact with COVID-19 patients (within one Metre of the infected person), especially if they do not cover their face when coughing or sneezing.
  • Indirect contact: The droplets survive on surfaces and clothes for many days. Therefore, touching any such infected surface or cloth and then touching one’s mouth, nose or eyes can transmit the disease.
  •  The incubation period of COVID 19 (time between getting the infection and showing symptoms) is 1 to 14 days.  
  • Some people with the infection, but without any serious symptoms can also spread the disease.

Treatment Available:

  • Emphasis on prevention.
  • Keeping good hygiene and by repeatedly washing hands.
  • Avoiding contact with patients.
  • Social Distancing and isolation.
  • Wearing mask if infected.
  • Lockdown to prevent spread.
  • No specific medication has been found as yet only supporting care in the hospital to prevent loss of life.
  • Scientists are working at the possibility of a vaccine.

Mechanism of Infection and Proliferation:

  • Step-1- Virus recognises that it has found the right cell to infect.
  • Step-2-Attaches to the host cell by way of spikes present on its surface. Virus is enclosed by a lipid membrane with spikes of protein on the outer surface.
  • Step -3-Spike protein directly interacts with the host cell membrane and merges to form an opening or pore.
  • Step-4-Virus transfers its genome (genetic material-RNA) into the host cell through this pore and eventually hijacking the host cell machinery to produce more viruses.
  • Step -5-A person gets infected and the proliferation of virus begins.
