Some 10-12 percent of the COVID-19 patients in the latest COVID-19 outbreak in Guangzhou are critically ill, Guan Xiangdong, a specialist in the Guangdong COVID-19 medical team, told media on Thursday. The proportion is higher than in the epidemic in Wuhan, and the following 20 regional clusters that took place across China, in which the proportion was usually 2-3 percent, 5-8 percent or “8-10 percent in a few areas,” Guan said to China Central Television (CCTV) on Thursday.
The relatively high proportion of severe and critically ill cases was probably caused by the highly pathogenic viral strains that spread in this wave of the epidemic in Guangzhou, Guan said.
Zhengli & Daszak study, September 2019 – “We conducted a cross-sectional study in the districts of Yunnan, Guangxi, and Guangdong, China… Serological testing of serum samples from 1,497 local residents revealed that 9 individuals (0.6%) in four study sites were positive for bat coronaviruses, indicating exposure at some point in their life to bat-borne SARSr-CoVs (n=7, Yunnan), HKU10-CoV (n=2, Guangxi), or other coronaviruses that are phylogenetically closely related to these.
