Japanese encephalitis vaccines first became available in the 1930s. [3] One of them was an inactivated mouse brain-derived vaccine (the Nakayama and/or Beijing-1 strain), made by BIKEN and marketed by Sanofi Pasteur as JE-VAX, until production ceased in 2005. The other was an inactivated vaccine cultivated on primary hamster kidney cells (the ...
Acute - the most common diseases caused by acute viral infections are encephalitis, flaccid paralysis, aseptic meningitis, post infectious and encephalomyelitis.; Chronic - the most common diseases caused by chronic viral infections are subacute-sclerosing panencephalitis, progressive multifocal leukoencephalopathy, retrovirus disease and spongiform encephalopathies.

For some forms of viral encephalitis, such as Eastern equine encephalitis and Japanese encephalitis, there may be a significant amount of necrosis of nerve cells. Following encephalitis caused by arboviruses, calcification may occur in the CNS, especially among children. Herpes simplex encephalitis tends to produce necrotic lesions in the CNS. [1]
The virus firstly struck pig-farms in the suburb of Ipoh in Perak with the occurrence of respiratory illness and encephalitis among the pigs, where it was initially believed to have been caused by Japanese encephalitis (JE), due to four serum samples from 28 infected humans in the area which tested positive for JE-specific Immunoglobulin M (IgM) which is also confirmed by the findings of the ...
A human case of Eastern equine encephalitis was identified in Massachusetts for the first time since 2020. Now the state's public health department is ringing the alarm in multiple communities to ...
