Abstract: Objective To investigate the Lyme Borreliosis status of infection of population in Xinjiang Prospecting Bureau of Henan oilfield to provide scientific basis for Lyme disease prevention and cure. Methods With census method epidemiological investigations were carried out in the crowd. All serum samples were detected by IFAT and ELISA for antibodies (IgG/IgM) against Borrelia burgdorferi. Cases of Lyme disease were made a definite diagnosis by epidemiology,clinical symptoms and serological results. The results were analyzed with χ^>2 test. Results Total 7 956 people were investigated in five times of which 1 037 people had a significant antibody titer,the average positive rate was 13.03% ( 12.07%-14.07% ). Among different professional populations,the positive rate in the wild prospecting population was the highest ( 16.36% ),in the wild constructing population was the second ( 12.63% ),and in the service population was the lowest ( 7.58% ),in which there were significant difference (χ²=101.1,P<0.01). The youngest infected with Lyme spirochete was 6 years old and the oldest was 61,but there were no significant difference in age groups (χ²=7.1,P>0.1). 665 cases with Lyme disease were confirmed,the prevalence rate was 8.36% . Conclusion The results showed that the population of Xinjiang Prospecting Bureau of Henan oilfield were infected with Lyme borreliosis,and in which Lyme disease has occurred. So the prevention and treatment must be enhanced.
