ERRATUM


ERRATA

In Am J Trop Med Hyg 70: 172–179, the names of the authors in the Dong Nai Study Group were inadvertently omitted. The names of those in the study group are as follows:

Nguyen Van My, Nguyen Thi Que Phuong, Nguyen Thi Thanh Ha, Ta Thi Tuyet Mai, Nguyen Thi Tuyet Anh, Truong Dinh Luat, Timothy Endy, Mary Jane Cardosa, Phaik Hooi Tio, Jean Paul Charlieu, Nicholas White, and Jeremy Farrar

The journal staff regrets the error.

Due to a printing error, page 236 did not appear in the March issue of the American Journal of Tropical Medicine and Hygiene (Am J Trop Med Hyg 70: 229–237). The missing page follows.

slightly inflated estimations of malaria rates and prevalences. Therefore, study results should not be generalized to the entire year. Because selection bias was identified in this study due to follow-up type, all multivariable models assessing associations with malaria outcomes during the study period were adjusted accordingly. Because some study variables, such as those regarding days of work lost and malaria episodes during lifetime, rely on individual recall, a certain degree of recall error may be present in this study. However, previous studies have demonstrated a high validity of self-reported malaria examinations by the study population.13,29

This study provided relevant information on the epidemiology of malaria in a hypoendemic Brazilian Amazon setting. It describes the sociodemographic characteristics of the individuals affected by malaria, their history of previous exposure and migration, present behaviors, and patterns of use of the malaria services, as well as hypotheses of the type of transmission expected to be more relevant in the area. Moreover, the study findings support the hypothesis that malaria transmission in this area was not sufficient to fully develop naturally acquired immunity against clinical manifestations. This information may help guide decision makers to specify effective control measures targeted to this population and transmission situation. Moreover, it provides measurable evidence of the burden of malaria in this area, especially regarding the days of work lost and days of hospital stay, which may influence political commitment with regard to this relevant public health problem. In addition, for researchers in particular, these results may be useful in guiding them in the choice of study variables and in providing background data and estimates for future studies in similar settings.
