Trends in Dengue Cases Imported into the United States from Pan America 2001–2012

The objective of this study was to improve risk assessments of travel on dengue (DEN) virus (DENV) distribution. We investigated the exposure risk of US citizens traveling to DEN-endemic Pan American countries. The number of DEN cases reported in 51 Pan American countries from 2001 to 2012 was compared to the population of the same countries. The number of US travelers visiting the Pan American countries was categorized by region, and travel-related DEN infections were analyzed. US residents visiting the Dominican Republic exhibited the highest traveler-related DEN incidence. Brazil showed the most DEN cases in its residents (>1 million reported cases in 2010). The number of DEN cases continues to rise as does international travel and the geographic range of potential DENV vectors. DENV risk assessments may be improved by analyzing the possible routes of entry. Underreporting remains an issue for calculating DENV transmission risk by country and region

Insights into Diversity in the Environmental Health Science Workforce

Creative Commons Attribution-NonCommercial 4.0 LicenseEnvironmental Health Science (EHS) professionals protect the public from environmental threats by conducting risk assessments and recommending preventative measures based on scientific findings. The EHS field itself is diverse in scientific areas (eg, air quality, water quality, food safety, healthy homes, preparedness, climate change, vectors/pests, tracking/informatics, occupational health, industrial hygiene) studied and evaluated by researchers and practitioners (https://www.neha.org/eh-topics). Scientific findings discovered in the EHS field help health leaders analyze and develop policies to protect health based on practical knowledge.1 Diversity is currently a wide-ranging societal topic, and this issue impacts the EH field. Many aspects related to diversity in EH involve the communities affected by environmental exposures and the EHS workforce serving these communities.OA publication support through Carolina Consortium agreement with Sag

Potential for sublethal insecticide exposure to impact vector competence of Aedes albopictus (Diptera: Culicidae) for dengue and Zika viruses

Presented for World Environmental Health Day, September 26, 2016 in Greenville, North Carolina.Dengue and Zika viruses (DENV and ZIKV, Family Flaviviridae, genus Flavivirus) are arboviruses that cause human epidemics. Due to lack of vaccines for many mosquito borne diseases, there is a need for mosquito control. In the United States and other regions, residual barrier insecticide sprays applied to foliage where female mosquitoes rest and/or sugar feed between blood meals are an important control method for anthropogenic day-active mosquitoes such as Aedes albopictus (vector of DENV and ZIKV). These mosquitoes are difficult to control using traditional sprays applied only at dusk or dawn when these mosquitoes are not active. In this exploratory study, we analyzed the extent to which ingestion of a sublethal dose of the active ingredient bifenthrin affected vector competence (i.e. infection, dissemination, and transmission) of Ae. albopictus for DENV and ZIKV
