With reference to the Neglected Tropical Diseases, consider the follow...
Explanation:
Statement 1: These diseases are caused only by viruses.
Statement 2: Chikungunya is one such disease which is affecting Subtropical countries.
Correct answer: 2 Only (b)
Explanation:
Neglected Tropical Diseases (NTDs):
- Neglected Tropical Diseases (NTDs) are a diverse group of communicable diseases that prevail in tropical and subtropical conditions in 149 countries.
- These diseases are caused by a variety of pathogens such as viruses, bacteria, protozoa, and helminths (parasitic worms).
- NTDs are most common in resource-poor settings, especially in rural areas with limited access to clean water, sanitation, and healthcare.
Statement 1: These diseases are caused only by viruses.
- This statement is incorrect.
- Neglected Tropical Diseases are caused by a variety of pathogens including viruses, bacteria, protozoa, and helminths.
- Examples of NTDs caused by viruses include dengue fever, Zika virus, yellow fever, and chikungunya.
- Other NTDs like leishmaniasis, lymphatic filariasis, schistosomiasis, and trachoma are caused by protozoa and helminths.
Statement 2: Chikungunya is one such disease which is affecting Subtropical countries.
- This statement is correct.
- Chikungunya is a viral disease transmitted to humans by infected mosquitoes, primarily Aedes aegypti and Aedes albopictus.
- It causes fever and severe joint pain, with symptoms similar to dengue fever.
- Chikungunya is endemic in many subtropical and tropical regions, including Africa, Asia, and the Indian subcontinent.
- Outbreaks have also occurred in Europe and the Americas.
- The disease is characterized by rapid spread and can cause significant morbidity, but is rarely fatal.
Conclusion:
- Neglected Tropical Diseases are caused by a variety of pathogens including viruses, bacteria, protozoa, and helminths.
- Chikungunya is one such disease caused by a virus and it affects subtropical countries.
- Therefore, the correct answer is option (b) 2 Only.
