I am sure many people have been reviewing the data about the SARS-CoV-2 epidemic. One of my main sources is at Worldometer. My question is geared toward a specific statistic they provide, namely the recovered/discharged versus deaths for closed cases.
Although there is currently some variability in the estimate of the fatality rate of SARS-CoV-2 (i.e. ~3% to ~14%), these estimates are much lower than the percentage of deaths relative to recovered/discharged for closed cases (~21%).
My understanding is that the latter number should be considered the more accurate estimate of how deadly the contagion is since only the closed cases represent terminal states of an individual. If we introduce cases that are still ongoing or the population which has not contracted the disease then, to me, this seems misleading.
However, the majority of individuals and reporting I have seen use the former statistics and so I feel as if I am missing a key insight. I am hoping that the community could help clarify this for me.
Also, it was challenging to determine which forum would be the best for this question. If there is a better one, please let me know and I will repost at that location.
Thank you very much for your time and stay safe!
