Options

A. Primary stage
B. Secondary stage
C. Tertiary stage
D. Neurosyphilis stage

Answer

To determine which stage of syphilis is characterized by skin rash, fever, and aches in joints and muscles, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Syphilis**: Recognize that syphilis is a sexually transmitted infection (STI) caused by the bacterium *Treponema pallidum*.

2. **Identify the Stages of Syphilis**: Syphilis progresses through several stages: primary, secondary, tertiary, and neurosyphilis.

3. **Examine the Primary Stage**: In the primary stage, the symptoms include painless sores (chancres) that appear on the genitals, rectum, or mouth. There are no systemic symptoms like fever or rash.

4. **Examine the Secondary Stage**: The secondary stage is characterized by systemic symptoms, including:
- Skin rashes
- Fever
- Swollen lymph glands
- Sore throat
- Muscle and joint aches

5. **Examine the Tertiary Stage**: The tertiary stage can lead to severe complications, including damage to the brain, nerves, eyes, and heart, but does not typically present with the symptoms listed in the question.

6. **Examine the Neurosyphilis Stage**: This stage involves neurological symptoms and complications but does not include the specific symptoms of skin rash, fever, and joint/muscle aches.

7. **Conclusion**: Based on the symptoms described in the question (skin rash, fever, and aches in joints and muscles), the correct answer is the **secondary stage** of syphilis.

### Final Answer:
The stage of syphilis characterized by skin rash, fever, and aches in joints and muscles is the **secondary stage** (Option B).
