The correct answer is (a) Basti.
Japanese encephalitis is a viral disease that affects the brain. It is spread to humans by mosquitoes that bite infected pigs or birds. The disease is most common in Asia, but it can also occur in other parts of the world.
The symptoms of Japanese encephalitis include fever, headache, vomiting, and seizures. In severe cases, the disease can cause coma and death.
There is no specific treatment for Japanese encephalitis. Treatment is supportive and includes measures such as providing fluids and electrolytes, controlling seizures, and treating any other complications.
The best way to prevent Japanese encephalitis is to avoid mosquito bites. This can be done by using insect repellent, wearing long-sleeved shirts and pants, and using mosquito nets.
In the recent epidemics of the Japanese Encephalitis, the most afflicted district in Uttar Pradesh was Basti. This is likely due to a number of factors, including the presence of a large population of pigs, which are the main reservoir for the virus, and the presence of mosquitoes that are capable of transmitting the virus.
The other options are incorrect because they are not districts in Uttar Pradesh.
