Encephalits is caused by the bite of

Options

A. Anopheles
B. Culex
C. Aedes
D. Culex and Aedes.

Answer

**Step-by-Step Solution:**

1. **Understanding Encephalitis**: Encephalitis is defined as an acute inflammation of the brain. This condition can arise from various causes, including viral, bacterial, or fungal infections, or as a result of an immune response to a previous infection.

2. **Identifying Causes**: The infectious agents responsible for encephalitis can be categorized into three main groups:
- **Common Viruses**: These include the Herpes Simplex Virus (HSV) and Epstein-Barr Virus (EBV).
- **Childhood Viruses**: This category includes viruses such as measles and mumps.
- **Arboviruses**: This group includes viruses like Japanese Encephalitis Virus (JEV), West Nile Virus, and Tick-borne Encephalitis.

3. **Focus on Arboviruses**: Among these, arboviruses are particularly significant as they are transmitted by vectors such as mosquitoes and ticks. Japanese Encephalitis is a notable example of encephalitis caused by an arbovirus.

4. **Transmission of Japanese Encephalitis**: The Japanese Encephalitis Virus (JEV) is primarily transmitted through the bites of mosquitoes. The vectors identified for JEV transmission include species such as Aedes albopictus and Culex pipiens.

5. **Answering the Question**: Given the options provided (Anopheles, Culex, Aedes, or Culex and Aedes), the correct answer is **Culex and Aedes**, as both of these mosquito types are known to be efficient vectors for the transmission of Japanese Encephalitis.

**Final Answer**: Encephalitis is caused by the bite of **Culex and Aedes** mosquitoes.
