Sample item

Under leprosy post-exposure prophylaxis, what is given to household contacts of a newly diagnosed case?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. A single dose of rifampicin

A single dose of rifampicin given to contacts after excluding leprosy and tuberculosis reduces the risk of developing leprosy by roughly 60 percent. It is used as part of national strategies to interrupt transmission.

Option by option

  • A. A single dose of rifampicin (correct)

    Correct. Single dose rifampicin is the recommended regimen.

  • B. Clofazimine monthly for a year

    Clofazimine monthly is not recommended.

  • C. BCG revaccination only

    BCG alone is insufficient for prophylaxis and is not the regimen.

  • D. Dapsone daily for 5 years

    Daily dapsone for years is not the current strategy.
