New study characterizes key attributes of the epidemiology of COVID-19 in China

​​As soon as novel coronavirus (COVID-19) emerged in China in late 2019, the disease became a pandemic. Many studies are conducted to explore and further understand the virus and its spread. Researchers from the Facul​​​​ty of Health Sciences at the American University o​f Beirut, ​​Qatar University and Cornell University published a new study with the aim of characterizing key attributes of the epidemiology of this infection in China.

In the study entitled "Characte​rizing key attributes of the epidemiology of COVID-19 in China: Model-based estimations," the researchers constructed an age-stratified mathematical model to describe the transmission dynamics and estimate the age-specific differences in the biological susceptibility to the infection, age-assortativeness in transmission mixing, case fatality rate (CFR), and transition in rate of infectious contacts following introduction of mass interventions. 

The study found that a​ge is a principal factor in explaining the patterns of COVID-19 transmission dynamics in China. The biological susceptibility to the infection seems limited among children, intermediate among young to mid-age adults, but high among those >50 years of age.
