Researchers at Fudan University and Northeastern University in the United States, writing in the journal Science, say China’s social isolation policy during the outbreak is effective in controlling the spread of the outbreak. The researchers looked at contact survey data from Wuhan and Shanghai, as well as contact tracking data from Hunan.
During the social isolation policy, people’s social contacts were reduced to between one and one in eight, with the vast majority of interactions being confined to within the family.
Researchers developed a communication model to study the effects of social isolation and school closures on the spread of the virus, and found that social isolation alone was sufficient to control the outbreak.
While the active closure of schools alone will not disrupt transmission, it can reduce the peak incidence by 40 to 60 per cent and delay the spread of the epidemic.
