[Objective] To understand the epidemic characteristics of major immunodeficiency diseases in Dalian from 2004 to 2008, and provide the basis for future prevention and treatment. [Method] The data of epidemic situation of hepatitis B and measles in Dalian from 2004 to 2008 were analyzed. [Results] The incidence of hepatitis B in 2008 was significantly lower than that in 2004 (P <0.01). The incidence of measles rose in 2005 and declined year by year after 2006 (P <0.01). The average annual incidence rates of hepatitis B in urban, suburban and rural areas from 2004 to 2008 were 20.16 / 100000, 34.60 / 100000 and 18.36 / 100000 respectively. The annual average incidence of measles was 0.86 / 100000, 2.63 / 100000, 0.37 / 100,000 (P <0.01). The incidence of measles, the second quarter accounted for 81.35%. The annual average incidence of hepatitis B was 33.88 / 100000, 12.30 / 100000 (P <0.01) and measles were 1.13 / 100000 and 1.06 / 100000 respectively (P> 0.05). The annual average incidence of hepatitis B was 20 ~ 44 years old the highest average annual incidence of measles <1 year old the highest. [Conclusion] The incidence of hepatitis B and measles in Dalian from 2004 to 2008 decreased obviously.
