(1/4) Study of a #COVID19 cluster at a family gathering, in which a 13-year old girl was the index case. Despite being only mildly symptomatic, she likely transmitted the virus to 11 of 19 family members (58%). One person was hospitalised, but recovered.

(2/4) The index case had been exposed to a large #COVID19 outbreak away from home. After returning home, she was tested with a rapid antigen test (four days after exposure) which was negative. She was asymptomatic at the time of the test, and developed symptoms two days later.
(3/4) Rapid antigen tests are generally less sensitive than a PCR test, meaning that not all infections may be detected.
Anyone who is exposed to a person with #COVID19 should self-isolate for 14 days, even if their test result is negative. It may be a false negative.

(4/4) Six relatives who visited for 10 hours on day 3 of the gathering, and for 3 hours on day 10, did not appear to become infected (4 tested negative).
These relatives did not wear face masks during the gathering, but remained outside and practiced physical distancing.
