1)Explained: Rate of COVID-19 spread in India, world :-Although COVID-19 cases have grown faster over the last one week, the transmission rate in India is lower than elsewhere.
Rate of transmission
Compare India’s low transmission rate (1.81) to that of Italy – between 2.76 and 3.25, according to the European Centre for Disease Prevention and Control.
This number is called a “reproduction number” or R0, used to describe the contagiousness of a disease.
When the R0 less than one, meaning not every infected person spreads the virus to another, the disease ceases to become an epidemic.
Above one(01), the cases increase exponemtially. Epidemiologists study out breaks by watching this exponential growth.
Epidemiologists have championed “social distancing” in order to “flatten the curve.”
2) What is Tablighi Jamaat? :- Tablighi Jamaat, which literally means a society for spreading the faith, is a Sunni Islamic missionary movement. The proselytising movement aims to reach out to ordinary Muslims and revive their faith, particularly in matters of ritual, dress, and personal behaviour.
Its roots lie in the Deobandi version of the Hanafi school of jurisprudence. It was launched by Deoband cleric and prominet Islamic scholar Maulana Muhammad Ilyas Khandhalaw in 1927 in Mewat.
Its emergence also coincided with Hindu proselytising movements.
In the first Tablighi conference held in 1941, approximately 25,000 people from across North India attended.
3)Explained: How does alcohol in sanitisers (and soap) kill the coronavirus?
Handwashing for 20 seconds at least kills the virus. When using a sanitiser, it should ideally have an alcohol content of 60% or more.
“The novel coronavirus has a lipid envelope. Soap being a detergent destroys the envelope. The same is true for alcohol. You see even when the virus comes out through droplets when an infected person coughs, it is still within a cell. Even if it isn’t, it can stay alive in surfaces for some time. It replicates only when within the cell. That is how soap or alcohol attacks the virus.”
