Abstract:
Malaria is an insect-borne disease transmitted by Anopheles mosquitoes or the importation of
Plasmodium-infected blood, posing a serious threat to human health and life safety. This study aims
to analyze the incidence of malaria in Qingdao at various stages from 1949 to 2021, to collate the
control measures taken at different epidemic stages to assess the effectiveness of malaria control, and
to identify a set of malaria control strategies suitable for Qingdao, while providing Chinese experience
for other countries or cities in their malaria elimination efforts. A retrospective survey was used to
collect information on malaria cases, control measures and prevention and control effects in Qingdao
from 1949 to 2021, and to evaluate malaria control strategies and measures in Qingdao. 704 155 cases
have been reported from 1949 to 2021, with three epidemic peaks: the incidence rate was 1715.9/100
000 in 1961, 1409.7/100 000 in 1965, and the most severe case occurred in 1972, with an incidence
rate of 1635.6/100 000 and a case count exceeding 90 000. Throughout the various stages of malaria
epidemics, Qingdao has effectively eliminated indigenous malaria by implementing diverse preventive
and control measures. Since the last indigenous case of Plasmodium vivax was reported in 2002, all
locally reported cases have been imported, mainly by returning migrant workers from Africa. This study
examines a range of malaria prevention and control strategies and interventions that are appropriate
for Qingdao. These measures have enabled Qingdao to successfully eliminate malaria and maintain
malaria-free status for more than 20 years. These measures can also serve as a reference for similarly
situated cities in Africa and Southeast Asia.
