Even more recently, the virus was reported in the Czech Republic. Scientists in the U.S. discovered the rare strain of encephalitis in birds that died in and around the Bronx Zoo. They believe the birds may have carried the disease that was then spread as mosquitos fed on the infected birds. More than 520 dead birds have been found in the New York City region, according to state health commissioner Dr. Antonia Novello. The birds, in the Western Hemisphere, never having been exposed to this before may be more likely to have a bad outcome because they have not developed any historic immunity to this virus.
More dead birds means more opportunities for mosquitos to pick up the disease and spread it.
While New York health officials and the CDC continue the investigation, authorities are asking residents to report dead birds to the Emergency Management Office. Scientists are continuing lab tests looking for the virus in brain samples, blood and spinal fluid. More than 100 cases will be re-examined as authorities admit the health toll may be greater than first thought. All Rights Reserved. Terms under which this service is provided to you.
