In the Americas, yellow fever virus transmission is a latent threat due to the proximity between urban and wild environments. Although yellow fever has nearly vanished from North and Central America, there are still 13 countries in the Americas considered endemic by the World Health Organization. Human cases usually occur as a result of the exposure to sylvatic yellow fever in tropical forested environments; but urban outbreaks reported during the last decade demonstrate that the risk in this environment still exists. The objective of this study was to identify spatial patterns and the relationship between key geographic and environmental factors with the distribution of yellow fever human cases in the Americas.

While the environmental correlates of global patterns in standing species richness are well understood, it is poorly known which environmental factors promote diversification (speciation minus extinct...
Data indicate that autism spectrum disorder (ASD) prevalence may be increasing and varies geographically. We investigated associations between residential location and ASD in the children of Nurses' H...
The existence of biogeographic patterns among most free-living microbial taxa has been well established, yet little is known about the underlying mechanisms that shape these patterns. Here, we examine...
Rhizospheric fungi play major roles in both natural and agricultural ecosystems. However, little is known about the determinants of their diversity and biogeographic patterns. Here, we compared fungal...
The concentrations and compositions of polychlorinated naphthalenes (PCNs) in sediments and suspended particulate matters (SPM) in the middle and lower reaches of the Yellow River were investigated. T...
The objective of this study is to study immune memory generated against the yellow fever vaccine (YFV) in participants who recently received the YFV vaccine. Volunteers who are planning ...
Age-related macular degeneration is one of the leading causes of blindness worldwide. The factors that induce the progression of geographic atrophy, the advanced form of dry age-related ma...
This clinical trial aims to test the effects of consuming two types of tomato (one ordinary cherry red tomato containing lycopene, and the other a yellow cherry tomato low in lycopene), on...
Nutritional profile of mother's milk is influenced by various factors including environmental, dietary and nutritional status of the mother. Given the huge diversity noted in nutritional s...
The purpose of this study is to determine whether immune globulin can limit the amount of yellow fever vaccine virus present in the blood after vaccination without compromising the immunit...
The area of medicine concerned with the effects on health and disease due to geographic factors such as CLIMATE, environmental conditions, and geographic location.
Medical specialty concerned with environmental factors that may impinge upon human disease, and development of methods for the detection, prevention, and control of environmentally related disease.
A multifactorial disease of CATTLE resulting from complex interactions between environmental factors, host factors, and pathogens. The environmental factors act as stressors adversely affecting the IMMUNE SYSTEM and other host defenses and enhancing transmission of infecting agents.
Component of the NATIONAL INSTITUTES OF HEALTH. It conducts and supports basic and applied research to reduce the burden of human illness and dysfunction from environmental causes by, defining how environmental exposures, genetic susceptibility, and age interact to affect an individual's health. It was established in 1969.
The exposure to potentially harmful chemical, physical, or biological agents in the environment or to environmental factors that may include ionizing radiation, pathogenic organisms, or toxic chemicals.
Tropical Medicine is the study of diseases more commonly found in tropical regions than elsewhere. Examples of these diseases are malaria, yellow fever, Chagas disease, Dengue, Helminths, African trypanosomiasis, Leishmaniasis, Leprosy, Lymphatic filaria...
