“…pulcherrimus is thought to be the main vector in Afghanistan (Brooker et al, 2006). Plasmodium vivax (VK210 and VK247 subtypes) was detected in specimens collected in Afghanistan (Rowland et al, 2002) and P. vivax circumsporozoite proteins were detected though enzyme-linked immunosorbent assay (ELISA) in wild-infected wild-infected mosquitoes (the vast majority of which were An.…”

“…NDVI was used to generate risk and distribution maps for diseases with arthropod vectors (Kalluri et al 2007), as well as for temporal models of disease outbreaks (Chretien et al 2007). Malaria and other mosquito-borne diseases such as West Nile virus seem to receive the most frequent attention and be particularly amenable to modeling efforts involving spatiotemporal data such as NDVI, due to the close causal link between rainfall and both mosquito abundance and NDVI (Brooker et al 2006, Gemperli et al 2006, Ceccato et al 2007, Britch et al 2008. But other zoonoses like Hantaan virus (Yan et al 2007), schistosomiasis (Clements et al 2008, Wang et al 2008, Ebola (Pinzon et al 2004a), bubonic plague (Kausrud et al 2007), leishmaniasis (Werneck et al 2007), Rift Valley fever (Anyamba et al 2009) and others have been found to have spatial and/or temporal components associated with NDVI variability.…”

This review highlights the latest developments associated with the use of the Normalized Difference Vegetation Index (NDVI) in ecology. Over the last decade, the NDVI has proven extremely useful in predicting herbivore and non-herbivore distribution, abundance and life history traits in space and time. Due to the continuous nature of NDVI since mid-1981, the relative importance of different temporal and spatial lags on population performance can be assessed, widening our understanding of population dynamics. Previously thought to be most useful in temperate environments, the utility of this satellite-derived index has been demonstrated even in sparsely vegetated areas. Climate models can be used to reconstruct historical patterns in vegetation dynamics in addition to anticipating the effects of future environmental change on biodiversity. NDVI has thus been established as a crucial tool for assessing past and future population and biodiversity consequences of change in climate, vegetation phenology and primary productivity.

“…22,23 Given the wide geographic distribution of respondents, actual malaria exposure during the period was unknown, and varied widely ranging from no risk in the mountainous regions to substantial risks in some of the northern and southeastern regions. 24 This study highlights issues with compliance and side effects experienced by U.S. Army soldiers taking long-term antimalarial chemoprophylaxis, which should be interpreted in light of the study's limitations. Comparison of side effect rates between MQ and doxycycline is challenging, as medication assignment was not random and MQ therapy was generally provided only to those intolerant of doxycycline.…”

Abstract. Long-term antimalarial chemoprophylaxis is currently used by deployed U.S. military personnel. Previous small, short-term efficacy studies have shown variable rates of side effects among patients taking various forms of chemoprophylaxis, though reliable safety and tolerability data on long-term use are limited. We conducted a survey of troops returning to Fort Drum, NY following a 12-month deployment to Operation Enduring Freedom, Afghanistan from 2006 to 2007. Of the 2,351 respondents, 95% reported taking at least one form of prophylaxis during their deployment, and 90% were deployed for > 10 months. Compliance with daily doxycycline was poor (60%) compared with 80% with weekly mefloquine (MQ). Adverse events (AEs) were reported by approximately 30% with both MQ and doxycycline, with 10% discontinuing doxycycline compared with 4% of MQ users. Only 6% and 31% of soldiers reported use of bed nets and skin repellents, respectively. Compliance with long-term malaria prophylaxis was poor, and there were substantial tolerability issues based on these anonymous survey results, though fewer with MQ than doxycycline. Given few long-term antimalarial chemoprophylaxis options, there is an unmet medical need for new antimalarials safe for long-term use.
