What is Encephalitis?

Encephalitis is an acute brain inflammation. It can cause a severe headache and confusion. It is very rare, treatable, and usually, spreads by animals or insects. The infection may be bacterial or viral. In some cases, encephalitis may be the result of an immune system disorder.

About 15% of encephalitis cases occur in the HIV-positive population.

Treatment of Encephalitis depends on age, condition and symptoms one is dealing with. Further, antibiotics can be useful if the bacteria is the cause of infection. But not every encephalitis is treated with antibiotics. So doctors focus on reducing the symptoms through pain killers, rest, sedatives (for irritability, aggressiveness, restlessness) and many other treatments.

It is curable with proper care. Thus, timely diagnosis and treatment are very important


We all know prevention is better than cure. The most common thing is to protect yourself from mosquitoes, like for instance, apply mosquito repellent. Additionally, avoid unhygienic places where you are more likely to get the infection. Since different viruses occur in different locations, it is very important to remain cautious.
