The poorest 20% don’t manage to meet even their routine expenditure required for day-to-day living, while the 20% above them have a slim margin in good times often destroyed by health or social emergencies or inflation.

2)Explained: How plasma therapy works, what India plans

India is all set to try out a therapy that involves attempting to jump-start the immunity of a serious patient by infusing some of the blood plasma of a person who has already recovered from the disease.

This is called convalescent plasma therapy and has in the past been used in many other diseases.

About Plasma:- Plasma is the matrix on which the blood cells float.

It also houses crucial components of immunity known as antibodies.

Antibodies are the immediate warriors who fight an invading pathogen – an antigen – to defeat it.

Once that is done, some blood cells function as memory cells so that they can identify and defeat the same enemy if and when it invades again by quickly producing the same antibodies.

The country’s apex medical research organisation, Indian Council of Medical Research (ICMR), is framing a protocol for infusing blood plasma from people who have recovered from COVID-19 into serious patients.

3)Ambient Air Quality Standards in India:-
