Abstract/OtherAbstract:
An epidemic of St. Louis encephalitis (SLE) occurred in Dallas, Texas, in the summer of 1966. A total of 545 suspected cases within Dallas city and county were reported, of which 145 were laboratory-confirmed as SLE virus infection. The greatest concentration of cases occurred in lower socioeconomic areas of the central part of the city in black populations. The attack rate and mortality rate increased markedly with age. The overall attack rate was 15.2 per 100,000, with a case fatality rate of 9.7%. During the course of the epidemic, most of the county was sprayed aerially with an ultra-low volume (ULV), high-concentration malathion mist. The effects of this treatment cannot be adequately assessed from the human epidemiologic aspect alone, but the spraying clearly reduced the number and infection rate of the vector mosquitoes.
