“…En la figura 3 puede observarse la incorporación en el análisis espacial de la dimensión de la altitud del suelo y de la red y el tipo de carreteras 35,36 para reconocer el papel que estas dos variables tuvieron en la intensidad de la transmisión de malaria (Plasmodium vivax), así como de la posible difusión espacial de la enfermedad.…”

“…16 Furthermore, imported infections present the potential for autochthonous transmission. 17,18 Competent anopheline mosquito vectors are found throughout the lower 48 states, 19 and in the past decade, local transmission has been documented in five states. 20 However, no instances of local transmission in the United States have been linked to refugee resettlement.…”

During May 4, 2007–February 29, 2008, the United States resettled 6,159 refugees from Tanzania. Refugees received pre-departure antimalarial treatment with sulfadoxine-pyrimethamine (SP), partially supervised (three/six doses) artemether-lumefantrine (AL), or fully supervised AL. Thirty-nine malaria cases were detected. Disease incidence was 15.5/1,000 in the SP group and 3.2/1,000 in the partially supervised AL group (relative change = –79%, 95% confidence interval = –56% to –90%). Incidence was 1.3/1,000 refugees in the fully supervised AL group (relative change = –92% compared with SP group; 95% confidence interval = –66% to –98%). Among 39 cases, 28 (72%) were in refugees < 15 years of age. Time between arrival and symptom onset (median = 14 days, range = 3–46 days) did not differ by group. Thirty-two (82%) persons were hospitalized, 4 (10%) had severe manifestations, and 9 (27%) had parasitemias > 5% (range = < 0.1–18%). Pre-departure presumptive treatment with an effective drug is associated with decreased disease among refugees.

“…1. Urbanization and migration are dynamic processes that work across geographic and temporal scales to affect forest loss and disease rates. 6,7 It has been recognized, specifically in Brazil, that as urban areas expand and improve infrastructure, malaria rates fall, consistent with the frontier malaria hypothesis-that malaria incidence particularly varies during early stages of urban development. 8,9 In addition, migration, which is ubiquitous throughout the Brazilian Amazon, 10 is a key determinant of malaria, because it alters the interface between humans and their environment.…”

Abstract. We respond to Valle and Clark, 1 who assert that "conservation efforts may increase malaria burden in the Brazilian Amazon," because the relationship between forest cover and malaria incidence was stronger than the effect of the deforestation rate. 1 We contend that their conclusion is flawed because of limitations in their methodology that we discuss in detail. Most important are the exclusion of one-half the original data without a discussion of selection bias, the lack of model adjustment for either population growth or migration, and the crude classifications of land cover and protected areas that lead to aggregation bias.1 Of greater significance, we stress the need for caution in the interpretation of data that could have profound effects on regional land use decisions.In a recent article, Valle and Clark 1 found that, in 401 cities in the Brazilian Amazon, both deforestation and percent forest cover in a 20-km area around cities were associated with an increase in malaria cases reported to the primary health clinic in the city. Valle and Clark 1 conclude that "conservation efforts may increase malaria burden in the Brazilian Amazon," because the relationship between forest cover and malaria was stronger than the effect of the deforestation rate.
