Explanation lettering: B = shown as A · E = shown as B · D = shown as C · A = shown as D · C = shown as E
D is correct. UKHSA guidance says a diagnosed case should be treated as soon as possible and should not wait for wider mass treatment. Prompt treatment reduces symptoms, complications and onward transmission. In parallel, the setting must identify close contacts, coordinate treatment rounds, ensure correct whole-body application or dosing, and repeat treatment at the recommended interval where applicable. Restricting therapy to microscopy-positive cases misses clinically diagnosed infestation, while cleaning without treating people cannot terminate transmission. Infection prevention measures and temporary contact precautions are proportionate to the setting and case type.
