Why the viral load of COVID-19 patients begins to decline after 7 days, but most severe cases and deaths occur after 15 days or more? Posted: 03 Apr 2022 11:21 PM PDT The viral load of patients infected with COVID-19 reached its peak on the 7th day and gradually decreased thereafter. However, it is extremely rare for patients to develop severe illness and death within 7 days. Most patients become severe or even die 15 days or more after infection. It was the COVID-19 virus that caused the cytokine storm that killed the patient?( Judging by the peak of the virus, and the peak of the death, it doesn't seem so.) Or is it because, after the COVID-19 virus kills epithelial cells in the lungs, it leads to secondary bacterial infections in the lungs, leading to pneumonia and the resulting immune system storm that ultimately kills the patient? Or is there something else? submitted by /u/guuble [link] [comments]
