ABSTRACT
This study aimed to analyze the epidemiological characteristics of hand, foot and mouth disease (HFMD) during 2008-14 in Wenzhou, China. The epidemiological data of HFMD retrieved from the Wenzhou Center for Disease Control and Prevention were retrospectively analyzed. HFMD infections with enterovirus 71 (EV71), Cox A16 or other pathogens were further verified by polymerase chain reaction (PCR) and real-time PCR. A total of 213 617 cases of HFMD were reported between 2008 and 2014 in Wenzhou. The average incidence was 384.31 of 100 000, and the fatality rate was 0.14. The incidence of HFMD peaked between April and July, and it occurred more frequently in males than in females. Approximately 92.68% of the HFMD patients were children aged <5 years. Nearly 80% of the cases were diagnosed within 2 days after onset. The major HFMD pathogen was EV71. This study suggested that appropriate comprehensive prevention and control measures should be taken to avoid the spread of HFMD.

Paragonimus infection was reported in a family of 8 members after consuming wine-preserved raw crabs. Seven members developed symptoms of fever, cough, sputum, fatigueness, chest pain, and abdominal pain during 2-3 months after crab feeding, while one member was normal. Serum samples were collected from the 7 members for anti-paragonimus antibody test, with 5 members showing positive, 1 weakly positive and 1 negative. In view of the epidemiological history, clinical symptoms, imaging and laboratory test results, this case was diagnosed to be a family-clustered paragonimus infection.

A total of 258 malaria cases with 2 deaths were reported during 2007-2014, including 148 vivax malaria cases, 106 falciparum malaria cases, and 4 ovale malaria cases. During 2007-2009, 86.0% (135/157) were vivax malaria cases with 3 indigenous cases. In 2010-2014, the proportion of falciparum malaria is increasing year by year, and all were imported cases. 98.8% were imported from Africa and other provinces in China. Most cases occurred among patients aged 20-49 years, and the male-to-female ratio was 3.16:1. Most patients were workers and commercial service personnel. The malaria epidemic situation is relatively stable in Wenzhou. Malaria control and elimination interventions should emphasize the monitoring and education of transient population to control the imported cases, and explore multi-sector coordination for malaria prevention and control.

OBJECTIVE: To understand the characteristics of malaria prevalence in Wenzhou City in 2013, so as to provide the evidence for improving the elimination program of malaria. METHODS: The epidemiological data of malaria in Wenzhou City in 2013 were collected from the Chinese information system for disease control and prevention, and analyzed with the descriptive epidemiological methods for epidemiological characteristics of malaria. RESULTS: Totally 34 imported malaria cases were reported in Wenzhou City in 2013 with the incidence of 0.37 per 100,000 people. Plasmodiumfalciparum, P. ovale and P. vivax were identified in 31, 1 and 2 cases, respectively. No death cases were reported, and 64.71% (22/34) of the cases were reported in Cangnan County, Lucheng District and Rui' an City. The malaria cases were mostly concentrated in persons aged 20-49 years with male to female sex ratio at 4.67: 1, and the predominant portion of cases were workers and commercial service personnel. Totally 97.06% of the cases were imported from Africa. CONCLUSIONS: The malaria endemic situation is relatively stable and no local malaria cases are reported in Wenzhou City in 2013. In order to achieve the goal of malaria elimination, the management and education of the transient population should be strengthened.

The first imported case of Plasmodium ovale infection in Wenzhou City was confirmed by microscopy and PCR test. The patient returned from the People's Republic of Congo to Wenzhou for three and a half months presented a history of fever with chills and rigors on April 30, 2012. The results from peripheral blood smear examination and PCR analysis confirmed a diagnosis of P. ovale infection. The patient was treated with chloroquine plus primaquine for eight days and the symptoms improved.
