What causes encephalitis?

Encephalitis is a serious disease, most of which is caused by viral infection. The early symptoms are similar to those of a cold, accompanied by fever. Many people treat it as a cold, which results in delayed treatment and bad consequences. What causes encephalitis? There are many factors that cause encephalitis. No matter what the factor is, the key to facing encephalitis is timely diagnosis and timely treatment.

Encephalitis is a common disease that affects men, women, young and old. Once it occurs, the disease progresses rapidly and requires timely treatment to minimize damage to the brain. Here is an introduction to how encephalitis is caused:

Viral encephalitis viruses do not have a cellular structure and are divided into two categories based on the different nucleic acid components: one is the deoxyribonucleic acid virus (DNA virus): including parvovirus, papillomavirus (which causes progressive multifocal leukoencephalopathy), adenovirus, herpes virus, and varicella-zoster virus. The other is the RNA virus: including picornaviruses (poliovirus, coxsackievirus, ECHO virus), arboviruses, myxoviruses (influenza virus), paramyxoviruses (measles virus and mumps virus), arenaviruses (lymphocytic choriomeningitis virus), and rhabdoviruses (rabies virus). Viral encephalitis can be divided into acute, subacute and chronic encephalitis according to the severity of onset. According to the type of virus and the route of infection, it can be divided into arbovirus, enterovirus, respiratory virus, herpes virus encephalitis, etc. Depending on the incidence of the disease, it can be divided into epidemic and sporadic encephalitis. It is generally believed that acute encephalitis represents acute viral infection, while subacute or chronic onset such as subacute sclerosing panencephalitis and corticostriatal spinal cord degeneration represent chronic viral infection.

The above introduces how encephalitis is caused. I hope it can help you find the cause and receive timely treatment. Encephalitis is divided into acute and subacute, both of which develop relatively quickly. The mortality rate of encephalitis is relatively high. The biggest reason is that it is easily treated as a common cold or other disease. When cold symptoms appear, especially accompanied by fever, you must take it seriously. It is best to have a blood test to rule out encephalitis, so that you can feel more at ease.
