ORS is needed in which of the following diseases?

Options

A. Cholera
B. Diphtheria
C. Tuberculosis
D. Whooping cough

Answer

**Step-by-Step Solution:**

1. **Understanding ORS**: ORS stands for Oral Rehydration Salt. It is a solution used to prevent or treat dehydration, especially due to diarrhea and vomiting.

2. **Identifying the Diseases**: We need to analyze the diseases listed in the question to determine which ones require ORS. The diseases mentioned are Cholera, Diphtheria, Tuberculosis, and Whooping Cough.

3. **Analyzing Cholera**: Cholera is a bacterial disease caused by Vibrio cholerae. It leads to severe diarrhea and vomiting, which results in a significant loss of fluids and electrolytes. Therefore, ORS is needed to replenish the lost fluids and salts.

4. **Analyzing Diphtheria**: Diphtheria is caused by Corynebacterium diphtheriae and primarily presents with symptoms like a sore throat and fever. It does not cause diarrhea or significant fluid loss, so ORS is not needed.

5. **Analyzing Tuberculosis**: Tuberculosis is caused by Mycobacterium tuberculosis and is characterized by symptoms like cough and fever. It does not lead to dehydration or fluid loss, so ORS is not required.

6. **Analyzing Whooping Cough**: Whooping cough, caused by Bordetella pertussis, is characterized by severe coughing fits. Similar to the other diseases, it does not cause diarrhea or dehydration, so ORS is not necessary.

7. **Conclusion**: Based on the analysis, ORS is needed in Cholera, but not in Diphtheria, Tuberculosis, or Whooping Cough. Thus, the correct answer is Cholera.

**Final Answer**: ORS is needed in Cholera.
