What are the different types of encephalitis viruses?
There are several types of encephalitis viruses. Encephalitis is an inflammation of the brain that can lead to slight symptoms similar to influenza or more serious and life -threatening, such as seizures and paralysis. Encephalitis viruses include mosquito viruses or tick bite, rabies virus and several types of herpes virus.
One of the more common encephalitis viruses is the Herpes Simplex virus. Herpes Simplex 1 is usually responsible for ulcers in humans. A person can obtain encephalitis after the initial exposition of herpes simplex 1 or can obtain it after the virus has been in the body for a while and becomes reactivated. Herpes simplex encephalitis is more common in young people under 20 or people for over 40 years. It is usually very serious and can be fatal. Epstein Barr is a virus that usually causes mononucleosis, while Varicella-Zoster virus usually causes falsepox in children and adults and shingles later in life. Most cases of encephalitis that are the result of Epstein Barr or Varicella-Zoster is a minrná.
other encephalitis viruses spread to people from ticks or mosquitoes. These viruses are known as Arboviruses. The Powassan virus, or Pow, spreads to people from the black -wired tick, located in North America and parts of Asia. Although Encephalitis from Pow are very rare in the United States and Canada, they are usually fatal in 10 percent of cases and have permanent neurological effects in approximately 50 percent of cases.
A number of encephalitis viruses spread from mosquitoes, including the St. Louis, Virus West Nile and La Crosse virus. Viruses usually start with birds and are then transmitted to people through mosquitoes that act as viruses vectors. Usually, the encephalitidyz mosquito viruses are mild and occur in older adults.
Several viruses that were previously common in childhood could also lead to encephalitis such as measles, polio and mumps. These viruses usually cause secondary fOrmu encephalitis because the person will first suffer from symptoms of the virus and then have signs of encephalitis. Vaccination significantly reduces the risk of a person to gain one of these viruses.
Encephalitis viruses are easy to prevent. If one plans to spend time outside in the area with ticks and mosquitoes, it should wear long pants, long -sleeved shirts and other protective clothing. Mosquito repellent is a necessity. People should also avoid others who have signs and symptoms of encephalitis and should not share food and drink with people who are sick.
