Title: Estimation of protection for COVID-19 in children from epidemiological information and estimate effect of policy in Japan Document date: 2020_3_30
ID: c5p0yp04_2
Snippet: Earlier research suggested that children might be less susceptible to COVID-19 for lifestyle-related factors such as lack of smoking and less vigorous immune response than that of adults [2] . Children might have some cross protection from non-novel coronavirus infection. Even though the reasons for it had not become clear, the number of children among patients was quite small.

Document: Earlier research suggested that children might be less susceptible to COVID-19 for lifestyle-related factors such as lack of smoking and less vigorous immune response than that of adults [2] . Children might have some cross protection from non-novel coronavirus infection. Even though the reasons for it had not become clear, the number of children among patients was quite small. In fact, even in Japan, the incidence rate including asymptomatic cases among children was 0.79 per million population compared to 5.97 for adults and 7.82 for elderly people as of 17 March. Incidence among children was approximately one-tenth that of elderly people. Therefore, this clear phenomenon must be incorporated into the model when predicting the outbreak.
