COVID‐19 started from one city of China in December 2019, but in a short span of time, it covered almost all over the world (WHO, 2020b). Nearly 216 countries of the whole world are struggling for their civilization and livelihood against the coronavirus pandemic. On January 11, 2020, China declared first death of their 61 years old citizen due to COVID‐19, who was exposed to the seafood market (WHO, 2020b), but now death reached exponentially to 357,736 on 29th May 2020 (WHO, 2020a).

On February 11, 2020, WHO announced this coronavirus disease as COVID‐19 (WHO, 2020c) and pandemic on March 11, 2020, after reaching the virus infection to 114 countries across the world.

COVID‐19 and SARS coronavirus are similar and because it is becoming a big threat to human civilization as consequences, online awareness programs were initiated and conducted worldwide by WHO (2020c).

Proper strategies and funds were set up by WHO globally to protect the countries with special focus to poor and weaker health infrastructure developing countries. The aim was to reduce the virus communication in society, dissemination of crucial information, providing proper healthcare and to minimize social and economical loss. WHO also focused on establishing an easy and effective diagnostic system to prevent infection (WHO 2020 c).

To prevent the infection socially, the lockdown was imposed globally, which resulted in the halt of all economic and social activity in society. This led to cease global supply chains badly resulting in the global economy in bad shape. All transport, manufacturing, hotel industry, educational sector, service industry and so forth were closed immediately, people were left to remain as to where they were at the time of lockdown announcement and during lockdown people started working from home, school and colleges classes are running online, a large number of people shifted on a digital platform.

But on May 30, 2020, this situation of coronavirus disease (COVID‐19) outbreak has become worse, as it contains 5,704,736 confirmed cases, 357,736 confirmed deaths across 216 countries. India also has 165,799 confirmed cases with 4,706 casualties (WHO, 2020d).

Now it is very clear that COVID‐19 is creating very disaster effects globally, people are getting panicked, emotionally unsecured, depressed and in a stage of confusion, unaware about facilities provided by the government, regarding reliable news sources, symptoms of COVID‐19 and its prevention with the cure.

How is the virus transmitted?

It’s likely that the Coronavirus Disease (COVID-19) originated in an animal species, and then spread to humans.

Person to person spread of the novel corona virus is reported, but it is not yet understood how easily this happens.

Other human coronavirus strains are spread from person to person through contaminated droplets from a person who is sick with the illness (through coughing or sneezing) or contaminated hands.

COVID-19 affects different people in different ways. Some people do not have any symptoms and may not even know they have the virus. You can still pass COVID-19 on even if you aren’t showing any symptoms, so it’s important to always follow the prevention advice.

How long does it take to develop symptoms?

The time from exposure to COVID-19 to the moment when symptoms begin is, on average, 5-6 days and can range from 1-14 days. This is why people who have been exposed to the virus are advised to remain at home and stay away from others, for 14 days, in order to prevent the spread of the virus, especially where testing is not easily available.
