Some viruses infect the brain and tissues surrounding it, which leads to neurologic viral diseases.

Examples of neurologic viral diseases are:

Viral meningitis
Rabies
Polio
Viral encephalitis
Clinical Manifestation

Confusion
Seizures
Fever
Drowsiness
Coordination problems
Transmission

Various neurological viruses transmit after getting bitten by an infected animal or bugs, like ticks and mosquitoes.

While viruses like poliovirus and enterovirus are communicable and transmitted when an individual comes in close contact with a person with a virus. These viruses can also get spread through contaminated items.

Treatment

There is no particular treatment available for a person with mild meningitis or encephalitis. Having OTC anti-inflammatories, taking proper rest, and drinking plenty of water helps to relieve the pain or headaches. In certain cases, physicians may recommend taking antiviral medication.
Person suffering from polio or serious viral meningitis or encephalitis may need further medical assistance like breathing assistance and intravenous fluids.
If any animal bites someone and is under suspicion to have rabies, a series of shots will be administered to the person, which will prevent the rabies virus from spreading in the body.
Prevention

Maintaining good hygiene
Try to avoid close contact with the person having the virus
Preventing ourselves from getting bitten by the insects
Keep your pets vaccinated to decrease the spread of rabies and also stay away from wild animals
Get a vaccine for both poliovirus and mumps virus
