To what extent do children transmit SARS‐CoV‐2 virus? – Wiley Online Library

The evidence to date suggests that children spread SARS‐CoV‐2 virus relatively rarely and that children are usually infected by symptomatic or pre‐symptomatic adults (in the first 48 h before they become symptomatic). During contact tracing, the China/World Health Organization joint commission recorded no episodes where transmission occurred from a child to an adult. A review of 31 family clusters of COVID‐19 from China, Singapore, the USA, South Korea and Vietnam, found only three (9.7%) clusters had a child as the index case and in all three clusters the child was symptomatic.
