Thank you for reading through my post and leaving a thoughtful question.

Based on my understanding, I would say that it is the same side of the problem but discussed from a different perspective. Basically, Dr. Shankara focuses on the clinical aspect of the problem whereas Dr. Casanova focuses on the molecular aspect of the problem.

Generally, the symptoms of individuals with mild COVID-19–which makes up the majority of those who were infected with SARS-CoV-2–often resolve within a week after infection. However, as Dr. Shankara Chetty had pointed out, those whose symptoms or inflammation persisted for eight days or more may be at a higher risk for developing severe Covid-19 or even long Covid. Hence, Dr. Shankara emphasizes the need to stop the inflammation with steroids and antihistamines using the 8th day as a cue.

However, to establish a clear and effective solution, we will need to look into what is causing some people to have persistent inflammation. And this post explains one of the many possible factors that cause persistent inflammation–that is the presence of autoantibodies that disrupt the normal immune response.

I hope I have answered your question. :D
