Abstract

During May-August 2013, a malaria outbreak comprising 874 persons in Shanglin County, China, was detected among 4,052 persons returning from overseas. Ghana was the predominant destination country, and 92.3% of malarial infections occurred in gold miners. Preventive measures should be enhanced for persons in high-risk occupations traveling to malaria-endemic countries.
Malaria is a potentially deadly disease caused by infection with Plasmodium spp. parasites, which are transmitted to humans through bites from infected Anopheles spp. mosquitoes. As part of global malaria elimination actions by the World Health Organization, in 2010, the government of China initiated the National Action Plan for Malaria Elimination to eliminate malaria by 2020 (1). In recent years, the incidence of malaria in China has decreased sharply to 0.18 cases per 100,000 persons in 2012 (2). However, imported malaria among persons returning from overseas malaria-endemic regions has been documented in some areas of China (3,4). These imported cases present a new challenge to malaria elimination in China. To facilitate formulation of more effective prevention and control measures for imported malaria at a time of rapidly increasing globalization, we describe the epidemiologic characteristics of a large outbreak of imported malaria among Chinese workers returning from overseas countries, in Shanglin County, Guangxi Zhuang Autonomous Region, in 2013.
Dr. Zhongjie Li is an epidemiologist at the Chinese Center for Disease Control and Prevention. His research interests include the epidemiology of infectious disease and early-warning system on disease outbreak detection.
