Abstract: Objective To study the morbidity rate,epidemical distribution,clinical symptoms and treatment of the cases bitten by red imported fire ants(RIFA),and to provide the scientific evidence for disease control and prevention.Methods(All the) peasant bitten by RIFA in Z village were screened and investigated to collect their epidemiological characters,clinical symptoms and treatments.Results Each family in the village had one or more members bitten by RIFA.The accumulative morbidity rate was(93.8%)((289/)308).The first suspect case bitten by RIFA occurred in 1999,and cases had been increasing year by year since then.Among the persons who were bitten by RIFA,there was no significant difference between male and female and among the persons from different ages.(78.5%) peasants were bitten in the field while cultivating,in which(81.7%) were bitten on four limbs.The clinic symptoms were mainly including itch-pain(100%),ruddy((99.2%)),blain((98.8%)),pimple((59.0%)),and severe symptoms such as systemic hypersusceptibility((0.8%)) and shock((0.8%)) rarely occurred.(85.3%) patients treated themselves,and no one died of the bite of RIFA.Anti-inflammation and anti-hypersusceptibility drugs had a good effectiveness.Conclusion Peasants are bitten by RIFA quite widely,but the clinic symptoms are mainly represented in localized part and patients have good prognoses.
