There are so many questions that still persist in managing coronavirus infection. How do we calculate the first day of the disease and when do we accelerate matters or rush to a hospital? Dr Mathew Varghese, a senior doctor at Delhi's St Stephen's Hospital, believes it is very important to look at timelines in the management of the disease. His viral Video on YouTube explains how the virus works once it is able to infect us and details the various stages and symptoms of the disease. Interestingly, he also says it's important to monitor fever levels on the fifth day to know if the illness is worsening, and not use paracetemol to suppress temperatures.
