Corona Virus Disease transmissible on 2019 is abbreviated as COVID-19 which is an infectious disease caused by a newly discovered Virus named as CORONA. The COVID-19 virus spreads primarily through droplets of saliva or discharge from the nose when an infected person coughs or sneezes, so it’s important that you also practice respiratory etiquette.

Variant name  First Identified and infected Countries
The Alpha strain Great Britain
The Beta strain  South Africa
The Gamma strain  Brazil
The Delta strain  India

According to the Lead WHO epidemiologist and COVID-19 technical lead, Dr. Maria Van Kerkhove, the Delta variant has certain mutations that allow the virus to adhere to human cells more easily. Experts are also seeing a higher viral load in individuals infection.


Delta is more contagious than the other virus strains.

Delta is the name for the B.1.617.2. Variant, a SARS-CoV-2 mutation that originally surfaced in India. The first Delta case was identified in December 2020, and the strain spread rapidly, soon becoming the dominant strain of the virus in both India and then Great Britain. According to Centers for Disease Control and Prevention (CDC) estimates, to the end of July, Delta was the cause of more than 80% of new U.S. COVID-19 cases.
