Impact of Covid Pandemic on the World.
The COVID-19 pandemic, also known as the coronavirus pandemic, is an ongoing pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It was first identified in December 2019 in Wuhan, China. The World Health Organization declared the outbreak a Public Health Emergency of International Concern in January 2020 and a pandemic in March 2020. As of 29 January 2021, more than 101 million cases have been confirmed, with more than 2.19 million deaths attributed to COVID-19.

Symptoms of COVID-19 are highly variable, ranging from none to severe illness. The virus spreads mainly through the air when people are near each other.[b] It leaves an infected person as they breathe, cough, sneeze, or speak and enters another person via their mouth, nose, or eyes. It may also spread via contaminated surfaces. People remain infectious for up to two weeks, and can spread the virus even if they do not show symptoms
