[Surveillance of epidemiological features for epidemic cerebrospinal meningitis in China during 1980s].
This paper reports the results of surveillance of epidemiological features for epidemic cerebrospinal meningitis in China during 1980s. Although the incidence of this disease in China in 1984 were up about 50% comparing with in 1983, its morbidities of recent years had been continued to decrease. The patients were distributed rather far apart from one another and the feature of cyclic incidence peak for epidemic cerebrospinal meningitis in 1980s was not obvious as former. However, the possibility which this disease will present prevalence still exists. Because the morbidity would begin to rise again after it decreased to the lowest level. At present, such rising signs have been appeared in some provinces. In addition, Neisseria meningitidis group B isolated from the cases tended to increase. The proportion of cases of young children was increased obviously in comparison with elder children or adults. This status makes the prevention of this disease by using meningococcal polysaccharide vaccine group A some difficulty. The authors also investigated and analysed the effect of normal throat flora of healthy people and other acute respiratory infectious diseases on the epidemic cerebrospinal meningitis.
