- Leprosy
- Trachoma
- Filaria
Show Solution
The Correct Option is B
Solution and Explanation
Mass chemoprophylaxis is the public health move of dosing an entire endemic population with a drug to break transmission, rather than waiting to treat only the sick. The question wants the disease where this blanket approach is not the standard plan.
Run through the list. Yaws programmes famously sweep through whole villages with penicillin or azithromycin, so mass treatment fits. Trachoma control under the SAFE strategy literally builds in community wide azithromycin distribution. Lymphatic filariasis elimination is driven by mass drug administration of DEC plus albendazole to everyone eligible in endemic districts.
Leprosy stands apart. Its control rests on finding cases early and putting them and their contacts on multidrug therapy, not on medicating the whole community. Since population wide chemoprophylaxis is not the recommended route for leprosy, it is the exception.
\[\boxed{\text{Leprosy}}\]
