Study of an Outbreak of Venezuelan Encephalitis in 1968
Abstract
An epidemic of Venezuelan encephalitis, which occurred in October 1968 in the District of Paez, State of Zulia, Venezuela, is described and analyzed. A total of 1,077 cases of the disease were registered, 150 of which included evident attack on the nervous system. Two deaths were attributable to the encephalitis, both in children less than one year old. There was a larger number of cases among children less than 6 years old; these were born after the last encephalitis epidemic in the region, which points to the cyclic activity of the virus. It was concluded that the virus is inactive in the interepidemic periods. The immunity conferred by the virus is apparently of long duration, as indicated by the small number of older patients and ill children less than one year old, the latter protected by transmitted maternal antibodies.
