Options

A. Viral encephalities
B. Meningococcal meaninngitis
C. Eastern equine encephalities
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which infection is primarily transmitted from person to person. This means we need to identify a communicable disease.

2. **Analyzing the Options**:
- **Option 1: Viral Encephalitis**: This is a viral infection that affects the brain. It is typically not transmitted from person to person; rather, it is usually spread through vectors like mosquitoes.
- **Option 2: Meningococcal Meningitis**: This is an infection of the protective membranes covering the brain and spinal cord. It is caused by the bacterium Neisseria meningitidis and can be transmitted through respiratory droplets or direct contact with an infected person, making it a communicable disease.
- **Option 3: Eastern Equine Encephalitis**: Similar to viral encephalitis, this is also primarily transmitted by mosquitoes and not from person to person.
- **Option 4: All of the Above**: This option suggests that all listed infections can be transmitted from person to person, which is incorrect based on our analysis.

3. **Identifying the Correct Answer**: Based on the analysis, the only infection that is chiefly transmitted from person to person is **Meningococcal Meningitis**.

4. **Conclusion**: Therefore, the correct answer to the question is **Option 2: Meningococcal Meningitis**.
