Covid 19 cases in India
March 7 news from Maharshtra Times
India Corona (Covid 19 ) cases 31
Today Corona (covid 19)crosses 54 lakhs
We are going to study a blood test which
Would tell us severity of Covid 19 which would
Give a guidelines for treating Covid 19 patients
Let us know what are WBC let us know
These are part of the blood cells called white
Cells or leucocytes generally famous for fighting the diseases .
The different cells make different types of WBC
1 )Lymphocytes 2) Neutrophils 3 ) Eosinophils
4)Monocytes 5)Basophils
We will concentrate on lymphocytes
Lymphocyte give us immunity. Innate immunity
By T lymphocytes , and adaptive immunity
By B lymphocytes.
Lymphocytes number range from 25% to 40%
Among WBC
When lymphocytes are less than 25
A term used is lymphocytopenia
In Covid 19 patients if lymphocytes are below 25 Covid 1 9 patient suffers from lymphocytopenia this predics disease severity
Of Covid 19
Lymphocytopenia may results due to
1) The virus might directly infect lymphocytes
Resulting in death of lymphocytes as and thus
Reducing number of lymphocytes
2) Inhibition of lymphocytes due to hyperlactic acidemia.
3) Lymphocytes express Corona virus receptor
ACE 2 and may be direct target of viruses.
