There are two recent studies that suggest that immunity lasts for at least a year and it is possible that it may last for decades, at least for some people. These studies have been made on bone marrow of the persons who have been infected by Corona virus Sars-CoV-2.
The first study on Persistent Cellular Immunity to SARS-CoV-2 Infection is as under:
SARS-CoV-2 is responsible for an ongoing pandemic that affected millions of individuals around the globe. To gain further understanding of the immune response in recovered individuals we measured T cell responses in paired samples obtained an average of 1.3 and 6.1 months after infection from 41 individuals. The data indicate that recovered individuals show persistent polyfunctional SARS-CoV-2 antigen specific memory that could contribute to rapid recall responses. In addition, recovered individuals show enduring immune alterations in relative numbers of CD4+ and CD8+ T cells, expression of activation/exhaustion markers, and cell division.
Summary We show that SARS-CoV-2 infection elicits broadly reactive and highly functional memory T cell responses that persist 6 months after infection. In addition, recovered individuals show enduring immune alterations in CD4+ and CD8+ T cells compartments.
The corona virus which started from Wuhan in China, decided not to visit any other province of China and seems to have been keeping that promise. No official of Chinese Communist Party came in contact with virus. No prominent leftist politician of influence got infected any where in the world, barring handful few exceptions. China except Wuhan could avoid infections but also it’s frequent and infamous and deadly variants.
India may be facing what is called second wave, has so far faced at least 7-10 variants. The present B-1.617 and B-1.617.2 have wrecked havoc. It happened last month like a cloud burst. Suddenly the active cases rose from on hundred thousand to three millions. And it is possible that this number leave out many with mild symptoms who could not be tested because of over load of work.
In all this mayhem, there is another pandemic, killing people or keeping them sick longer. This is called tele-medicina doctors. It is a new concept and there are no guide lines as to how the doctors should behave. The video call make it possible to observe the patient and all these electronic gadgets like Gluco-meter, Oxy-meter, Blood pressure monitors etc are providing good feedback but the Doctors have blown away the opportunity and created pandemic of their own. First of all the doctors seem to be obvious of simple protocols and SOPs of pandemic which are frequently released by AIIMS, Delhi for medical fraternity. All are available in videos but these Doctors are too smart or too busy to watch these videos. They do not care if a few patients die or live. After all it is the luck of patient.
It is official now. India is facing second wave of infections. Riding on the ‘Marriage Season” and gross violation of all protocols, the Corona Virus has hit India again. With 53,476 new cases and 251 deaths, the total infections rose to 11,787,534 cases which include 395,192 active cases and 160,692 fatalities, it is apparent. The number of daily infections has risen five times in less than a month.
The vaccination program of India and the world shows the total number of vaccinations so far:
SARS-CoV-2 was first reported from China. Within three months, it evolved to 10 additional subtypes. Two evolved subtypes (A2 and A2a) carry a non-synonymous Spike protein mutation (D614G).
A new study:
A phylodynamic analysis of over 70,000 SARS-CoV-2 coronaviruses worldwide, sequenced until July2020, and found that the mutant sub-type (614G) out competed the pre-existing type (614D), significantly faster in Europe and North-America than in East Asia. A study has concluded that:
Human health is an issue. The longevity of humans may have increased but they are not healthy. Why people in old age has to use a walker and carry a bag of Urine and a diaper full of excreta? Modern medicine may have progressed in military science especially surgery but it has very little to offer for healthy living.
Pandemic from China
This pandemic from China has exposed the myth that good health care infrastructure is a sign of good health. The fact is that providing food is not enough if it is not healthy and does not boost immunity. But what is right food?
India had lowest rate of fatalities in this Pandemic and it is not due to squalor. It is due to personal hygiene and the herbal food which people of India take which is based on the principles of Sanatan Dharma and Ayurveda.
What are the core principles and how any person can take advantage of these principles has been explained in depth in this book. Sanatan Dharma is not a belief. It is a human science. This book explains this science of life step by step.
Not a religion:
When we talk about Sanatan Dharma there is a tremendous amount of intellectualization. There is this sect against that sect. There is this practice placed against that practice. It is made out as if the rituals define the Dharma. The rituals do not determine the doctrine.
Doctrine is diagnosis of the ailment which has been diagnosed. Now all these sects, practices and rituals are different experiments to deal with the different problems. Follow no ritual. Follow yourself and see what is making you unhealthy and even sick. Stick to the principles and continue with your own religious belief but do take care of your health.It is even better if you are healthy. Read the book and know what you are doing right.
It is free for two more days.
The practices which are prescribed with fancy names like Spirituality, Mindfulness or Inner Engineering are components of Sanatan Dharma. Just like Yoga, whose name mercifully remains same.
