TLDR
Analysis of this record and Pacific and Indian Ocean sea surface temperature anomalies, coupled with satellite normalized difference vegetation index data, shows that prediction of Rift Valley fever outbreaks may be made up to 5 months in advance of outbreaks in East Africa.Abstract:
All known Rift Valley fever virus outbreaks in East Africa from 1950 to May 1998, and probably earlier, followed periods of abnormally high rainfall. Analysis of this record and Pacific and Indian Ocean sea surface temperature anomalies, coupled with satellite normalized difference vegetation index data, shows that prediction of Rift Valley fever outbreaks may be made up to 5 months in advance of outbreaks in East Africa. Concurrent near-real-time monitoring with satellite normalized difference vegetation data may identify actual affected areas.read more

TL;DR: These new risk maps and infection estimates provide novel insights into the global, regional and national public health burden imposed by dengue and will help to guide improvements in disease control strategies using vaccine, drug and vector control methods, and in their economic evaluation.

Emerging Infectious Diseases of Wildlife-- Threats to Biodiversity and Human Health
TL;DR: These phenomena have two major biological implications: many wildlife species are reservoirs of pathogens that threaten domestic animal and human health; second, wildlife EIDs pose a substantial threat to the conservation of global biodiversity.
Journal ArticleDOI
Impact of regional climate change on human health
TL;DR: The growing evidence that climate–health relationships pose increasing health risks under future projections of climate change is reviewed and that the warming trend over recent decades has already contributed to increased morbidity and mortality in many regions of the world.

TL;DR: To improve the ability to predict epidemics in wild populations, it will be necessary to separate the independent and interactive effects of multiple climate drivers on disease impact.

TL;DR: In this paper, the authors compile the largest contemporary database for both species and pair it with relevant environmental variables predicting their global distribution, showing Aedes distributions to be the widest ever recorded; now extensive in all continents, including North America and Europe.

A comparison of the vegetation response to rainfall in the Sahel and East Africa, using normalized difference vegetation index from NOAA AVHRR
TL;DR: In this article, the relationship between rainfall and Normalized Difference Vegetation Index (NDVI) in East Africa and the Sahel has been analyzed, and the most important conclusions of this last conclusion are as follows: above this threshold, rainfall is no longer the limiting factor in vegetation growth and/or NDVI is not a good indicator of vegetation growth.

Rift Valley fever virus (family Bunyaviridae, genus Phlebovirus). Isolations from Diptera collected during an inter-epizootic period in Kenya
TL;DR: The isolation of virus from adult male and female A. lineatopennis which had been reared from field-collected larvae and pupae suggests that transovarial transmission of the virus occurs in this species.

Forecasting Zimbabwean Maize Yield Using Eastern Equatorial Pacific Sea-Surface Temperature
TL;DR: In this article, the authors present data show-ing a strong correlation between an El Nino index and both rainfall and maize yield in Zimbabwe, with more than 60% of the variance in yield accounted for sea surface temperatures in the eastern equatorial Pacific Ocean.

Rangeland production and annual rainfall relations in the Mediterranean Basin and in the African Sahelo Sudanian zone.
TL;DR: In this article, the relationship between annual rainfall and range production in Mediterranean Basin and the Sahelian Sudanian tropical zones of Africa was studied and a correlation between average range production and average rainfall over large geographic areas was found.
