Filarial is transmitted to man by

Options

A. Culex
B. Aedes
C. Anopheles
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding Filarial Worms**: Filarial worms are parasitic worms that can cause diseases in humans, such as lymphatic filariasis. They are transmitted through vectors.

2. **Identifying the Vectors**: The primary vectors that transmit filarial worms to humans are mosquitoes. These mosquitoes act as intermediaries in the transmission process.

3. **Types of Mosquitoes**: There are several types of mosquitoes that are known to transmit filarial worms:
- **Culex Mosquito**: This type is commonly found in urban and semi-urban areas. It is one of the main vectors for filarial transmission.
- **Aedes Mosquito**: This mosquito is prevalent in endemic islands of the Pacific and is also involved in the transmission of filarial diseases.
- **Anopheles Mosquito**: This type primarily spreads filarial diseases in rural areas.

4. **Conclusion**: All three types of mosquitoes—Culex, Aedes, and Anopheles—are capable of transmitting filarial worms to humans. Therefore, the correct answer to the question is that filaria is transmitted to humans by various types of mosquitoes.

**Final Answer**: Filarial is transmitted to man by mosquitoes (Culex, Aedes, and Anopheles).
