**Question:** WHO considerations regarding Dracunculosis eradication, all are true except
A. Dracunculosis eradication is supported by the World Health Organization (WHO).
B. The primary mode of transmission is through the consumption of contaminated water.
C. The treatment involves a single dose of ivermectin.
D. Eradication efforts are focused on improving sanitation and hygiene in endemic areas.
**Correct Answer:** **D. Eradication efforts are focused on improving sanitation and hygiene in endemic areas.**
**Core Concept:** Dracunculosis, also known as lymphatic filariasis, is a mosquito-borne parasitic disease caused by the filarial worm, Wuchereria bancrofti. The World Health Organization (WHO) has developed strategies to control and eradicate the disease.
**Why the Correct Answer is Right:** Dracunculosis eradication is supported by the WHO, and the primary mode of transmission is through the consumption of contaminated water. Treatment involves a single dose of ivermectin, which is a specific drug for filariasis. The focus of eradication efforts is not solely on improving sanitation and hygiene but also includes mass drug administration (MDA) and vector control measures.
**Why Each Wrong Option is Incorrect:**
A. Although WHO supports filariasis eradication initiatives, the focus of these efforts is not limited to supporting a single organization or individual.
B. Dracunculosis is primarily transmitted through the bite of an infected mosquito, not by consuming contaminated water.
C. While a single dose of ivermectin is a part of the treatment strategy, it is not the sole approach, as mentioned above.
**Clinical Pearl:**
Improving sanitation and hygiene in endemic areas is crucial to prevent the transmission of filarial worms, but the primary mode of transmission is through mosquito bites, not water consumption. This emphasizes the importance of vector control measures, such as insecticide-treated bed nets and indoor residual spraying, along with MDA and environmental management, to achieve effective filariasis eradication.
