How To Spread Disease Encephalitis


What is encephalitis?
Encephalitis, or inflammation of brain tissue, is rare, affecting about 1 to 200,000 people each year in the United States. When hit, it can be very serious, causing personality changes, seizures, weakness and other symptoms depending on the part relates to the brain. Children, the elderly and people with weakened immune systems are most vulnerable. This is usually caused by one of many viral infections, so it is sometimes called viral encephalitis.

Many people who have fully recovered the brain. The most appropriate treatment for the patient and the possibility of return depends on the relevant virus and the severity of inflammation.

In acute encephalitis, a more common among infants, infection, directly affect brain cells. In parainfectious encephalitis, inflammation of the brain form most frequently in adults, the brain and spinal cord are inflamed within 1-2 weeks after a viral infection or bacterial infection.

What are the causes?
Viral encephalitis can occur during or after infection with many viral diseases, including influenza, herpes, measles, mumps, rubella, rabies, varicella and arbovirus infection, including West Nile virus.

Herpes simplex virus type 1 is a cause more frequent and severe viral encephalitis. Encephalitis associated with herpes can become rapidly and can cause seizures or mental status changes, and even lead to coma and death. Occurs when the herpes simplex type I, the virus travels to the brain, rather than go through the body to the surface of the skin and produces its most common symptom, herpes. Early diagnosis and treatment of herpes simplex encephalitis can be life saving. There are more susceptible to encephalitis, if you have herpes.

Arbovirus brain, is another form of viral encephalitis. This is caused by different viruses that are carried by arthropods, including insects (eg mosquitoes) and arachnids (eg ticks). Unlike herpes, seasonality of arboviral infections occur mainly in summer and early fall, and are concentrated in specific regions, as in the case of encephalitis in St.

In rare cases, bacterial, fungal, parasitic, or rickettsial cause inflammation of the brain. Cancer, and even exposure to certain drugs or toxins can cause inflammation of the brain.
