CDC: Teen gave COVID-19 to 11 relatives across 4 states – Chicago Tribune

The report said the initial patient, a 13-year-old girl, was exposed to COVID-19 during a large outbreak in June. A rapid antigen test four days after her exposure came back negative, before her symptoms began. Two days later she had some nasal congestion, her only symptom. That day she traveled with her parents and two brothers to attend a large family gathering, which began the following day, according to the CDC report.
