NOTE: The route of transmission describes the way in which a positive case got the COVID-19 virus. We learn this information through case investigation interviews. Community spread means people have been infected with the virus in an area and are unsure how or where they got it from. Congregate setting refers to an environment where a large number of people reside, meet or gather in close proximity for an extended period of time (e.g. college housing, long-term care facilities, correctional facilities, adult group homes). Contact to Known Positive means that the positive case was able to identify who they were infected by in the past two weeks before they became sick. Their exposure may have been in the household, at a social gathering, workplace, or school.
