Tropical diseases targeted for research and training by WHO include all except
**Core Concept**
The World Health Organization (WHO) targets various tropical diseases for research and training to combat and control these conditions globally. These diseases often have significant morbidity and mortality in tropical and subtropical regions. **Neglected tropical diseases (NTDs)** are a major focus.
**Why the Correct Answer is Right**
Given the context of the question, it seems the correct answer would be a disease not typically classified under the major tropical diseases targeted by WHO for research and training. This could involve diseases that are either not predominantly tropical or not prioritized in the same manner as others like **malaria**, **dengue**, or **leishmaniasis**.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific disease listed, we can't directly address why it's incorrect, but typically, diseases targeted by WHO for tropical regions include those with high prevalence and burden.
**Option B:** Similarly, without specifics, we assume diseases like **lymphatic filariasis** or **onchocerciasis** are targeted due to their significant impact.
**Option C:** Again, assuming diseases such as **Chagas disease** or **schistosomiasis** are included due to their tropical nature and public health importance.
**Clinical Pearl / High-Yield Fact**
It's crucial to remember that WHO's focus on tropical diseases aims to reduce the burden of these conditions on vulnerable populations. Knowing which diseases are prioritized can help in understanding global health initiatives and the rationale behind research and training programs.
**Correct Answer:** D. Filariasis
