Exposure settings as documented in contact tracing data compiled by Public Health England, August–December 2020. All data show categories where exposure to infected contacts occurred in England by week and do not infer transmission. (a) Contacts by exposure setting. These are the settings where a person who tested positive for SARS-CoV-2 reported that they met with and potentially exposed their contacts (forward contact tracing). Work is ongoing to link contacts to future cases and to determine where transmission occurs. (b) Locations reported by people who tested positive for SARS-CoV-2 as possible exposure settings, defined as locations visited in the 3–7 days prior to symptom onset, or test date if asymptomatic (backward contact tracing). (c) Common locations reported by people who tested positive for SARS-CoV-2. Two or more individuals who tested positive reported the same location, defined by the same postcode, as a possible exposure setting in the 3–7 days prior to symptom onset, or test date if asymptomatic (backward contact tracing). Information on this type of event and the location are recorded but not information on contacts. (d) As (c) but with relative frequency of reported settings on the y-axis.
