RESUMO

Experience with twenty-five cases of acute encephalitis believed to be of viral origin has been analyzed. There is serological evidence that three of these cases were due to St. Louis virus. An unknown virus was isolated from the serum of one patient. In most of the cases, onset of illness was sudden. Fever, headache and mental change were the main symptoms. There was a mortality rate of 16 percent. It is significant that in about 35 percent of the cases, there was some residual defect after illness. (Summary)

RESUMO

Serological studies of blood specimens collected in Grenada in 1956 indicate that dengue infections have been prevalent in certain regions of the island. Ilheus virus infections, if they occur, are relatively uncommon. The only yellow fever immune individuals were over 50 years old. No evidence of existence of Mayaro infection was found. (AU)

RESUMO

Although hemagglutination-inhibition studies with Group B arboviruses are known to show cross reactions to a marked degree, nevertheless when survey specimens are analyzed according to the specific agent believed to have produced neutralization test immunity, characteristic pattern of immune response occur which are interpretable. Multiple infections, however, produce a pattern which does not admit of easy analysis. (Summary)

RESUMO

The first reported outbreak of St. Louis encephalitis in Canada occurred in the summer of 1975 in southern Ontario -- in the Windsor-Sarnia-Chatham area, the Niagara region and the city of Toronto. Hemmagglutination inhibition and complement fixation testing of serum samples collected during the outbreak confirmed that St. Louis encephalitis virus was the etiologic agent. Furthermore, this virus was isolated from brain tissue of a patient who died. This outbreak was probably an extension of the outbreak that occurred in the United States that summer. It was the first outbreak of arbovirus encephalitis in the province of Ontario. (AU)
