Name any three disease transmitted through vectors.

Explanation

### Step-by-Step Solution:

1. **Understanding Vectors**: Vectors are organisms that carry and transmit pathogens (disease-causing microorganisms) to other organisms. They do not cause the disease themselves but facilitate its spread.

2. **Identifying Diseases**: We need to name three diseases that are transmitted through vectors.

3. **Listing the Diseases**:
- **Malaria**: This disease is caused by the Plasmodium protozoan and is transmitted by the female Anopheles mosquito.
- **Dengue**: This disease is caused by the dengue virus and is transmitted by the Aedes aegypti mosquito.
- **Chikungunya**: This disease is also transmitted by the Aedes aegypti mosquito and is caused by the chikungunya virus.

4. **Final Answer**: The three diseases transmitted through vectors are:
- Malaria
- Dengue
- Chikungunya
