BackgroundPlasmodium vivax re-emerged in 1993 and has now become a major public health problem during the summer season in South Korea. The aim of this study was to interpret and understand the meaning of seroepidemiological studies for developing the best malaria control programme in South Korea.MethodsBlood samples were collected in Gimpo city, Paju city, Yeoncheon County, Cheorwon County and Goseong County of high risk area in South Korea. Microscopy was performed to identify patients infected with P. vivax. Antibody detection for P. vivax was performed using indirect fluorescent antibody test (IFAT).ResultsA total of 1,574 blood samples was collected from participants in the study areas and evaluated against three parameters: IFAT positive rate, annual antibody positive index (AAPI), and annual parasite index (API). The IFAT positive rate was 7.24% (n = 114). Of the five study areas, Gimpo had the highest IFAT positive rate (13.68%) and AAPI (4.63). Yeongcheon had the highest API in 2005 (2.06) while Gimpo had the highest API in 2006 (5.00). No correlation was observed between any of the three parameters and study sites' distance from the demilitarized zone (DMZ).ConclusionsThese results showed that P. vivax antibody levels could provide useful information about the prevalence of malaria in endemic areas. Furthermore, AAPI results for each year showed a closer relationship to API the following year than the API of the same year and thus could be helpful in predicting malaria transmission risks.

“…If we combine the interpretation with the timeliness of treatment, it is observed that even though the majority occurring within 48 hours, when it is more than 48h, it was a protective factor. Some explanation about the organization of malaria control actions in the Indigenous population can be found in a study on the municipality of São Gabriel da Cachoeira, which has the most indigenous people concentration in state of Amazonas [34].…”

Background In Brazil malaria is most frequent in the Amazon region, mainly in the Amazonas state, where it is found the most proportion of indigenous people of the whole country. It is remarkable publications about malaria in the Amazon, although information on malaria in indigenous populations is still poorly explored. Objective Identify factors associated with malaria in indigenous populations. Methods Cross-sectional study of positive cases of malaria in the state of Amazonas, Brazil, from 2007 to 2016. Secondary data were obtained from the Epidemiological Surveillance Information System for Malaria and from the Mortality Information System, both from Brazil. To tackle with race missing data, cases with no race fulfilled were classified according to the probable location where infection occurred. This way, was imputed indigenous race for those which the probable infection location was indigenous village (aldeia). Variables tested with race were: sex, age, schooling, microscope surveillance slide type, parasitic infection species, parasitemia level, and timeliness of treatment. Multivariate logistic regression was used. Results A total of 1,055,852 cases of malaria were notified in the state of Amazonas. Among the factors that associate malaria and indigenous peoples, the most significant were sex, children and high levels of parasitemia. The magnitude of Plasmodium vivax infection is higher than

“…In this sense, Brazilian National Health System (SUS) Primary Care should tailor its actions directed towards them, taking into consideration the way they organize themselves, so as to favor health promotion and the prevention of diseases such as malaria. 20,21 High mobility of the indigenous in frontier areas, difficulties faced by health teams in accessing these regions and the persistent incursion of prospectors and miners hamper malaria control actions in these regions. Constant mobility in these areas also contributes to the changing epidemiological profile of malaria.…”

Objective: to describe the profile and incidence of malaria cases among indigenous and non-indigenous people on the Brazil-French Guiana border, between 2007 and 2016. Methods: this is a descriptive study based on analysis of cases notified on the Malaria Epidemiological Surveillance Information System (SIVEP-Malaria), organized using Tableau 10.3. Results: a total of 21,729 cases were notified in the period; the highest annual number of notifications was 3,637 (16.7%) in 2009, 1,956 (53.8%) of which related to indigenous people, representing annual parasite incidence (API) of 261/1,000; higher risk of infection was found in the Kumenê base area (API between 13 and 534/1,000) and the Manga base area (API between 55 and 448/1,000); children accounted for 20.0 to 40.0% of notified cases, while pregnant women accounted for 2.0% among non-indigenous people and 1.0% among the indigenous. Conclusion: malaria case distribution was unequal between indigenous and non-indigenous people, with greater occurrence among the indigenous.
