According to an investigation by Noah Schwartz at the Centers for Disease Control and Prevention in Atlanta, Georgia, and his colleagues, the girl was exposed to SARS-CoV-2 in June. After a rapid test suggested that she was not infected, she joined 13 family members for an extended stay in a 5-bedroom house (N. G. Schwartz et al. Morb. Mortal. Wkly Rep. ; 2020). Family members neither wore masks nor maintained distance from each other.

In January, the authorities in Wuhan, where the coronavirus outbreak began, halted travel out of the city in an attempt to control the spread of the virus that causes COVID-19. But Hong Kong relied on a programme that included widespread testing, quarantining of those who had been in contact with infected people, and distancing measures such as school closures.

Lancet Public Health ; 2020). 153554b96e
