||Person to person
Transmission in Zhuhai appears to be occurring mainly within close groups such as families.
The development of the epidemic in Zhuhai parallel’s Wuhan’s population movements and control. Local transmission was mainly aggregated within family groups, and evidence suggested that a small number of cases or carriers may pass on infection beyond the 14-day limit.
What did they do?
This study described numbers of cases in Zhuhai, Guangdong Province, China to try to understand the patterns of transmission.
This is a description of a group of observed cases and is not necessarily representative beyond its time and geographical context.
