Objective Through analyzing the national statutory
reporting data on
typhoid,
paratyphoid fever in 2012,we were trying to understand the whole picture of
typhoid,
paratyphoid fever at the national level as well as to understand the
trends and characteristics of
typhoid and
paratyphoid fever in provinces with high
incidence rate,so as to the development of prevention and control
strategies of the
diseases in those high-
incidence rate provinces.
Methods We descriptively analyzed the national
typhoid and
paratyphoid fever statutory
reporting data which was reported through
disease surveillance information
reporting system in 2012.Results 11 998 cases with
typhoid and
paratyphoid fever were reported with 3 fatal ones,in 2012 in the whole country.The
incidence rate was 0.89 per 100 000.Compared to the data gathered in 2011,the
incidence rates of
typhoid/
paratyphoid fever increased by 1.20%.The total number of the confirmed cases on
typhoid and
paratyphoid fever was 6522 and was accounted for 54.36% of the total cases,in which
paratyphoid fever accounted for 36.86%.Cases were mainly involved
farmers and followed by
students and
children.
Incidence rates of
typhoid and
paratyphoid fever in
children aged 0-4 years old appeared the highest (respectively 1.31/100 000 and 0.46/100 000).Yunnan,Guizhou,Guangdong,Guangxi,Zhejiang,Hunan and Xinjiang provinces (autonomous regions) were identified as provinces with high-
incidence rates of
typhoid and
paratyphoid fever.During 2005-2012,the
incidence rates in most of the above high-
incidence provinces showed a downward trend,except for in Guangdong which had only showed a slight change.There were variations on peak period and highly-hit
population in seven high-
incidence provinces.Conclusion The
incidence rate of
typhoid/
paratyphoid fever was in a relatively low level in
China.Prevention and control
strategies on the
diseases in
children under 5 years old remained a challenge,warranted more
work to be done.The epidemiological situation is still severe in some high-
incidence rate provinces.
