TL;DR: An analysis of data from the Shenzhen Center for Disease Control and Prevention identified 391 SARS-CoV-2 cases and 1286 close contacts shows that isolation and contact tracing reduce the time during which cases are infectious in the community, thereby reducing the R.

TL;DR: This work shows that heightened surveillance and isolation, particularly contact tracing, reduces the time cases are infectious in the community, thereby reducing R.CoV-2's overall impact, however, its overall impact is uncertain and highly dependent on the number of asymptomatic cases.

TL;DR: This study suggests that mean temperature, relative humidity and wind speed might be risk factors of children HFMD in Shenzhen, and the interaction analysis indicates that these meteorological factors might have played their roles individually.

TL;DR: Although none of the participants in this study had virologically confirmed H7N9 infection, the high proportion of poultry workers with serologic evidence of H7n9 infection between May and December 2013 suggests a substantial risk of mild H7 N9 infections in this group, supporting stricter control measures in live poultry markets.

TL;DR: It is suggested that an intermittent, non-stable excretion of low-level viral RNA may result in recurrent-positive occurrence, rather than re-infection.
