Not all cases who reported funeral exposure explicitly reported whether they had touched the corpse. Cases who reported non-funeral exposure could report multiple types of exposure: belongings—“touched or shared the linens, clothes, or dishes/eating utensils of the case [contact]”; bodily fluids—“touched the body fluids of the case (blood, vomit, saliva, urine, feces)”; in same household—“slept, ate, or spent time in the same household or room as the case”; direct physical—“had direct physical contact with the body of the case”. Relationship was not reported for every exposure. We grouped reported relationships into classes: “close family” is defined as siblings, marital, and parent-child relationships; other family members are considered “extended family”; “neighbour” is defined as tenants, lodgers, landlords, and neighbours; “health care” is defined as HCW-patient relationships and caregivers, or any reference to a patient; “other” includes traditional healers, contacts through religious practice, and transport contacts. Type of exposure and relationship type are illustrated graphically in Figure d in S1 Text.
