Absence of Nosocomial Transmission of Imported Lassa Fever during Use of Standard Barrier Nursing Methods
|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|
