Common cold vir s saved lives in India
NEW DELHI: One of the biggest mysteries of the Covid-19 infection in India relative to other countries like the US and UK has been the lower mortality recorded in India.
An explanation has been posited in a study carried out by scientists of National Institute of Immunology and AIIMS and published in Frontiers in Immunology, a top-rated medical journal.
The researchers found that 66% of blood and plasma samples collected in pre-Covid times from the individuals with no history of exposure to the coronavir s had high frequency of CD4+T cells that responded robustly to the non-spike domain of SARS-CoV-2, the vir s that causes Covid-19.
More importantly, there were at least 21% samples of unexposed healthy donors that responded to the SARS-CoV-2 spike prein.
“The presence of T cells that are responsive to SARS-CoV-2 spike prein and non-spike prein in persons who have never been exposed to Covid could be because of exposure to other coronavir ses that cause the common cold,” expned Dr Ashok Sharma, associate professor, department of biochemistry, AIIMS.
According to Dr Nimesh Gupta, lead author of the study and head of the vaccine immunology division at NII, the cross-reactive T cells from coronavir ses that cause common cold may not prect from Covid infection, but by responding to the SARS-CoV-2 prein, they may limit the severity of the disease.
The authors concluded in the study that the cross-reactive CD4+ T cells might not be implicated in solely terminating the viral infection, but they might limit the vir s burden and reduce the course of symptomatic infection leading to lower in dence of severe disease.
Dr N K Mehra, emeritus scientist and former dean of AIIMS, said that the mortality rate of Covid in India is less than 1.5% when in countries such as the US, it is above 3%.
印度传染病研究所名誉科学家、前院长N K Mehra博士表示，印度的新冠肺炎死亡率低于1.5%，而美国等国家的死亡率高于3%。
“In Meco, the Covid mortality rate is above 10%,” he added.
Mehra said previous exposure to coronavir ses that cause the common cold was certainly one of the reasons behind the lower mortality rate in India.
Looks like Maharashtrians and Punjabis don't suffer from the common cold which is why the mortality rate is highest in these two states.
another report to save the go nment from its real failures
Most of the Indians prefer home made foods than packed restaurant foods. Home made foods are prepared with care which improves immunity in one. Whereas the packed foods contains 'unwanted' stuff which create more problem to those eat it regularly and such foods have absolutely no immunity strength.
We have been dealing with more vir ses than all formats put together is one of the reasons, be it vir ses in water, air, etc etc.
still there is no scope for any complacency . public must scrupulously follow medical norms .
Another reason is under counting. Did the study consider it
Due to the timely alertness of Modiji's Gt.
The Indian diet has a lot of tumeric and antiodants from spices. Compare this to a Western diet devoid of this on a regular basis. This also is a factor.
it's art of hiding data.. when my father died there was another more than 10 people died in same hospital. but go nment was reporting only 5 death in entire city with population of 55 lakh. the real number was more than 100 death that day
Mystery: reduced testing which expns the antibodies in many people , Nd reduced reporting Of the death eg: covid patient death reported as death due to cardiac arrest or respiratory failure( which was due to Covid)
Lo Mortality . . . Is it directly proportional to under reporting ?!
Earlier they reported it was due to the way modi handled pandemic now they are saying it is due to T cells
Here is the mystery. COVID IS A HOAX.
Mortality rate may be low but any family hit with covid19'in India faced financial ruin in form of hospital bills, fake treatments!
Day to day eating habits which we inherited from our ancestor since ages is better than west.
This is all because of Modi Ji's policies. Scientists will find a way to expn everything but it is clear that Indians are saved by Modi ji.
Some morons have not seen the completely wiped off sections of western cities. Don't laugh India has been very fortunate. Either our DNA or something else has saved us from those scenes. Experts on CNN last July cmed as much as 40-50 million deaths in India.
