A new virus that has been passed from pigs to humans in Malaysia and Singapore produces a distinctive, and very dangerous, type of encephalitis in humans, according the first neurological study of the disease, published in this month's Annals of Neurology, the scientific journal of the American Neurological Association.
Studying cases of the virus that have appeared in the past year among slaughterhouse workers in Singapore, a group of neurologists has identified the particular set of symptoms and brain injuries that make the Nipah virus version of encephalitis (brain inflammation) different from other types of viral encephalitis.
