A patient having fever at intervals of 48 hours , is suffering from

Options

A. Malignant or benign tertian malaria
B. Benign tertian malaria
C. Malignant tertian fever
D. Quartan malaria

Answer

To determine the condition of a patient experiencing fever at intervals of 48 hours, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Fever Cycle**:
- In malaria, fever cycles are characterized by specific intervals. The typical pattern includes a cold stage, a fever stage, and a sweating stage.

2. **Identify the Types of Malaria**:
- There are three main types of malaria relevant to this question:
- **Benign Tertian Malaria**: Caused by Plasmodium vivax or Plasmodium ovale, characterized by fever every second day (48 hours).
- **Malignant Tertian Malaria**: Caused by Plasmodium falciparum, also characterized by fever every second day but with more severe symptoms.
- **Benign Quatern Malaria**: Caused by Plasmodium malaria, characterized by fever every third day (72 hours).

3. **Analyze the Symptoms**:
- The patient has a fever every 48 hours, meaning they have fever on one day, no fever the next day, and fever again on the following day.

4. **Match the Symptoms with Malaria Types**:
- Since the patient has a fever every second day, this aligns with both benign tertian malaria and malignant tertian malaria, as both present with fever every 48 hours.

5. **Conclusion**:
- Given the options and the typical presentation of the fever cycle, the patient is most likely suffering from **Benign Tertian Malaria** or **Malignant Tertian Malaria**. However, since the question does not specify the severity of symptoms, the most appropriate answer is **Benign Tertian Malaria**.

### Final Answer:
The patient having fever at intervals of 48 hours is suffering from **Benign Tertian Malaria**.
