| the efficacy of japanese encephalitis vaccine in henan, china: a case-control study. | a population based case-control study to evaluate japanese encephalitis (je) vaccine efficacy was carried out in gusi county, henan province, china from june to september in 1991. this study showed that the je vaccine had a strong protective effect. the estimate of the vaccine efficacy was 78% (95% ci = 16-94%). an unimmunized child was at 4.54 times greater risk of developing je than were fully immunized children during the study period. the present study may have underestimated the vaccine eff ... | 1994 | 7667706 |

| the effect of ddt spraying and bed nets impregnated with pyrethroid insecticide on the incidence of japanese encephalitis virus infection. | a retrospective investigation was conducted to evaluate the effectiveness of ddt residual indoor spraying and bed nets impregnated with pyrethroid insecticide for japanese encephalitis control in southern henan province, china. ddt residual indoor spraying had no effect on the incidence of japanese encephalitis, but it was greatly reduced after the introduction of pyrethroid-impregnated bed nets. only a small effect on outdoor biting densities of culex tritaeniorhyncus was found, although the nu ... | 1994 | 7886751 |
| the protective effect of bed nets impregnated with pyrethroid insecticide and vaccination against japanese encephalitis. | a population-based case-control study to evaluate the protective effect of bed nets impregnated with pyrethroid insecticide and of vaccination against japanese encephalitis was carried out in gusi county, henan province, china from june to september 1991; 50 cases and 100 matched controls were studied. bed nets impregnated with pyrethroid insecticide greatly decreased the risk of infection among children under 10 years old, and vaccine efficacy was 78% (95% ci 16%-94%). we suggest that impregnat ... | 2012 | 7886752 |
| socio-economic status and micro-environmental factors in relation to the risk of japanese encephalitis: a case-control study. | in a population-based case-control study in southern henan province, central china, children suffering from japanese encephalitis (je) were compared with neighborhood controls matched by age and sex in terms of several social and environmental variables. factors found by crude analysis to be associated with an increased risk of je included lower family income, lower parental education, living in houses near the periphery of villages and poor quality of houses. when adjustment was made for confou ... | 1995 | 8629060 |
| molecular characterization of japanese encephalitis viruses circulating in pigs and mosquitoes on pig farms in the chinese province of henan. | since the first chinese case report of japanese encephalitis, japanese encephalitis virus (jev) has circulated in china for at least 60 years. even though pigs play a critical role in the jev transmission cycle information on the prevalence of jev in pigs has not been investigated in china. as the central chinese province of henan has the largest human population in china, a history of serious jev and is the largest pig producing province it was chosen for this study. we have found that currentl ... | 2013 | 22945473 |
| prognostic factors of early sequelae and fatal outcome of japanese encephalitis. | a clinical case control study to identify prognostic factors present at hospital admission associated with early sequelae and fatal outcome of acute japanese encephalitis (je) was carried out in gusi county, henan province, central china from june to september 1991. a total of 70 patients with laboratory-confirmed acute je were studied, of whom 3 cases died and 33 cases had neurological or psychiatric sequelae at the end of three months follow-up. the results showed that acute je at younger age, ... | 1995 | 9139378 |
