    Abstract

    We give an update to the original paper posted on 2/17/20 -- now (as of 3/1/20) the China deaths are rapidly decreasing, and we find an exponential decline to the power law similar to the that predicted by the network model of \citet{vazquez_polynomial_2006}. At the same time, we see non-China deaths increasing rapidly, and similar to the early behavior of the China statistics. Thus, we see three stages of the spread of the disease in terms of number of deaths: exponential growth, power-law behavior, and then exponential decline in the daily rate.

Objective: We aim to compare the severity and mortality between male and female patients with both COVID-19 and SARS, to explore the most useful prognostic factors for individualized assessment. Design, Setting, and Participants: We extracted the data from a case series of 43 hospitalized patients we treated, a public data set of the first 37 cases died of COVID-19 in Wuhan city and 1019 survived patients from six cities in China. *注，本文为预印本论文手稿，是未经同行评审的初步报告，其观点仅供科研同行交流，并不是结论性内容，请使用者谨慎使用.

    • Forecasting the Cumulative Number of COVID-19 Deaths in China: Can More Lives Be Saved? Zuqin Zhang, Cheng Long, Wei Yao, Qi Ying, Xinmiao Fu doi: https://doi.org/10.1101/2020.03.02.20030064 Abstract Background: An outbreak of 2019 novel coronavirus diseases (COVID-19) caused by SARS-CoV-2 is on-going in China and appears to approach late phase. It is highly demanding to estimate how many COVID-19 patients will die eventually. In this study, an estimate of the potential total number of COVID-19 deaths in mainland China, Hubei Province, Wuhan City, and other provinces is provided. The results may help to eluate the severity of the epidemic and facilitate mental health care. *注，本文为预印本论文手稿，是未经同行评审的初步报告，其观点仅供科研同行交流，并不是结论性内容，请使用者谨慎使用.
