Coronavirus Disease 2019 Rotator Graphic for (U.S. Air Force Graphic by Rosario “Charo” Gutierrez)

Let’s wind up our watches and clock to 2019, going out with your friends to your favourite eateries, family trips and outings, partying, visiting your local malls and what not? Feeling nostalgic enough? Now let the reality set in, think about the things which have changed, what role did we play in it? How are we coping with it? What are we doing to prevent it? Did you ever think that you will live through the pandemic? Let’s talk about it in detail.


Covid-19 is caused by a novel coronavirus, thus later named as SARS-CoV-2 by the experts of the International Committee on Taxonomy of Viruses (ICTV). This is a committee of the Virology Division of the positive single-stranded, non-segmented and enveloped viruses. It derives from the Latin origin word, in which corona means crown. It is named so, as this appears as a crown when viewed under an electron microscope.

31st  December 2019

This virus first appeared in Wuhan, the commercial centre and the sprawling capital of China’s Hubei province. It was first reported at the WHO Country office in China on 31st December 2019.

10th January 2020

WHO issued complete guidelines online to countries on how to detect, test and manage cases which are detected based on the information of virus at that particular time. This guideline was imparted to WHO’s regional emergency director to share with WHO delegates in the nation.

Based on encounters with MERS and SARS, infection and prevention control guidance were published to protect healthcare workers suggesting airborne precaution for aerosol-generating procedures.

12th– 13th  January 2020

 The genetic sequence of COVID-19 was publicly shared by China. Officials confirmed a case of COVID-19 in Thailand, this was the first case recorded outside China.

22nd  January 2020

WHO, after researching in China stated that there was evidence of human- to- human transmission of the virus in Wuhan but more research was done to understand the full extent of transmission.

30th  January 2020

WHO Director-General reassembled the Emergency Committee; the Emergency Committee reached an agreement and directed the Director-General that the outbreak constituted the Public Health Emergency of International Concern (PHEIC).

WHO’s situation report for 30th January reported that there were 7818 confirmed cases in total around the world with the majority of cases in China, while 82 cases were reported outside China in 18 different countries.

11th March 2020

Gravely concerned by both severities of the situation and alarming level of spread, WHO made the judgement that COVID-19 can be characterised as a pandemic.

The best way to stop corona virus transmission is to follow preventive measures.


Wear a mask that covers both your nose and mouth. Masks act basically as a barrier to help prevent your respiratory droplets that might travel into the air while we cough, sneeze, talk or shout from reaching others. Studies show that masks help in reducing the spray of droplets when worn over your nose as well as mouth. Mask can act as your saving grace against COVID-19.

There are a variety of masks:

  • Cloth masks
  • Surgical masks
  • K-95 masks.

You would have heard about double masking, let’s see if it has any pros or not?

Double masking refers to layering one mask over the other.

Why is it recommended?

  • BETTER FIT: Outer mask will keep the inner mask in place as it will apply gentle pressure making the inner one fit more closely on the skin and a better seal.
  • INCREASED FILTRATION: According to CDC, layering a cloth mask over the surgical mask is one of the best practices as more the layers, more will be the filtration power.


As sanitisers and disinfectants help in preventing the spread of both virus and bacteria, they can act as a holy grail against the virus.

  • Washing your hands regularly with soap and water for 20 seconds can kill germs and viruses.
  • Sanitisers with 60% of alcohol are imperative. WHO’s recommended formula containing 80% alcohol (ethanol) kills 99% of germs.
  • Cleaning and sanitizing your home regularly.


Maintaining a physical distance of 6 feet or at least two arm’s length can avoid the transmission. As COVID-19 spreads through droplets from the mouth or nose which remains live for hours or days on a surface, distancing can help in limiting ways to come in contact with contaminated surfaces and people.


COVID-19 vaccines are safe and effective. It is advisable to receive the complete schedule of vaccines for protecting oneself and the people around. Most of the vaccines have shown efficacy of 70-90% within a short period that is from two to three months when it was observed.

Let’s hold on to the feeling that we were talking about at the beginning of the blog. We have persevered so much, let’s have a little bit of patience and let’s follow all the safety protocols to overcome this hurdle (COVID-19).
