Objective To understand the incidence of measles in Baoding from 1999 to 2007 and analyze the causes of the epidemics. Methods Epidemiological analysis of measles surveillance data from 1999 to 2007 was performed. Results A total of 4591 suspected cases of measles were reported from 1999 to 2007 in Baoding City. A total of 3091 suspected measles cases were reported, with an average annual incidence of 3.17 / 100 000. The incidence rate was maintained at 0.5 / 100,000 in 1999-2002. From 2003 to 2007, The incidence began to rise somewhat, reaching 11.73 / 100,000 in 2006. The cases were distributed with obvious seasonal peaks. The cases from March to May accounted for 68.13% of the whole year. The incidence of males was higher than that of females, and the age of onset had the tendency of migrating to older and not yet immunized people. Immunization in measles History, history of no immunization and history of immunization were unknown, accounting for 24.58%, 38.15% and 37.27% respectively.
