TL;DR: It is found that social distancing alone, as implemented in China during the outbreak, is sufficient to control COVID-19, and children 0 to 14 years of age are less susceptible to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

TL;DR: The findings indicate that strict containment, movement restrictions, and increased awareness of the population have contributed to interrupt transmission of SARS-CoV-2 outside Hubei, and an early peak of infectiousness, with possible transmission before the onset of symptoms is suggested.

TL;DR: This preprint is withdrawn for the time being because the total number of confirmed cases of COVID-19 in mainland China has reached 18 times of the number in the manuscript.

TL;DR: The authors found that most of the secondary transmissions could be traced back to a minority of infected individuals, and well over half of transmission occurred in the presymptomatic phase, which could help in the design of infection control policies that have the potential to minimize both virus transmission and economic strain.

TL;DR: Based on individual records of 1178 potential SARS-CoV-2 infectors and their 15,648 contacts in Hunan, China, the authors estimated key transmission parameters.
