Risk category Description Action
No risk (category 1)
No contact with the case-patient; casual contact with the case-patient (e.g., sharing room without direct contact with any potentially infectious material)
Inform of absence of risk; give category 1 (general) fact sheet
Low risk (category 2)
Close direct contact with the case-patient (e.g., general routine medical/nursing care, handling of clinical/laboratory specimens), but did not handle body fluids or wore personal protective equipment appropriately
Self monitor† for fever and other symptoms compatible with Lassa fever; report to the safety officer nurse if fever >38°C or new somatic symptoms, with further evaluation as necessary; give category 2 fact sheet
High risk† (category 3) Unprotected exposure of damaged skin or mucous membranes (e.g., mucosal exposure to splashes, needlestick injury) to potentially infectious blood or body fluids; or unprotected handling of clinical laboratory specimens Report own temperature daily‡ and report this temperature and any new somatic symptoms to the safety officer nurse every day, with further evaluation as necessary; give category 3 fact sheet
