A new symptom of the swine flu

Four children in Dallas have developed neurological symptoms caused by the new H1N1 influenza virus, commonly called swine flu. According to a report in Thursday's edition of the Centers for Disease Control and Prevention's Morbidity and Mortality Weekly Report, two boys age 7 and 10 developed seizures and two older boys, age 11 and 17, developed hallucinations, difficulty standing and slowed speech. The symptoms were most likely caused by swelling and inflammation of the brain produced by the virus.

The four boys were among 405 laboratory-confirmed cases of H1N1 infection in the Dallas area and 44 hospitalizations. The results suggest that there have probably been many other cases elsewhere in the country that have not yet been reported to the CDC. Experts do not find the results surprising because about 5% of all childhood cases of encephalitis and similar brain problems are caused by seasonal flu.
