[Methods] Descriptive epidemiological methods were used to analyze the reported information of statutory group B infectious diseases of all medical institutions in Liaoyuan City reported by the epidemic network in 2011. [Results] In 2011, 13 kinds of group B infectious diseases were reported in the city, with 2 646 cases, the incidence rate was 224.90 / 100 000; 10 deaths (5 AIDS, 1 syphilis and 4 pulmonary tuberculosis) with a mortality rate of 0.85 / 100 000 The case fatality rate was 0.38%. The first three infectious diseases with the highest incidence were viral hepatitis (1050 cases), tuberculosis (839 cases) and syphilis (469 cases). The incidence of Type B infectious diseases was 251.59 / lakh in urban areas and 207.29 / lakh in rural areas, with 259.35 / lakh in males and 184.45 / lakh in females; 0 ~, 5 ~, 15 ~, 35 ~, ≥65 years Respectively 87.59 / 100,000, 146.98 / 100,000, 203.14 / 100,000, 249.66 / 100,000, and 297.43 / 100,000.
