Link between dengue epidemics, high temperatures during strong El Nio season

ScienceDaily: Epidemics of dengue are linked to high temperatures brought by the El Nio weather phenomenon, a University of Florida scientist working with an international team of researchers has found. The findings are particularly timely as the most intense El Nio in nearly two decades is emerging in the Pacific, raising the concern that a major increase in cases of dengue will occur throughout Southeast Asian countries early next year. The results of the study appear in issue of the Proceedings of the National...

ClimateWire: High temperatures are the driving factor behind massive dengue outbreaks in Southeast Asia, researchers have found. Though the infection waxes and wanes among many variables like human movement, rainfall, mosquito vector abundance and host immunity, heat emerged as the standout factor in large dengue epidemics. The World Health Organization reports that dengue infects 100 million people each year and infection rates have increased thirtyfold over the past 50 years (ClimateWire, Nov. 13, 2013)....
How Dengue Fever Could Hasten Malaria's Deadly March on Africa

Nature World: Dengue fever is not to be taken lightly, but compared to malaria, it is a far less deadly mosquito-transmitted disease. Unfortunately, the illnesses tends to share very similar starting symptoms, causing frequent misdiagnoses in areas endemic for both diseases. Now new research is showing that these mistakes not only impact individual patients, but could be helping malaria become an even greater danger. "We believe dengue to be one of many diseases with classic fever and headache symptoms that...
Dengue spread flies under the radar amid #Ebola scare

Agence France-Presse: One of the most familiar sounds in Malaysia's capital is the approaching drone of a fumigation fogger spewing thick white plumes of insecticide, part of so-far futile efforts to arrest a spiralling dengue fever outbreak. Malaysia is among several countries across Asia and Latin America grappling with a mosquito-borne virus that is proving tough to eradicate as it infects millions. While the Ebola threat has captured headlines, the World Health Organization (WHO) warns that dengue -- while far...
Brazil Fights Dengue With Modified Mosquitoes

Nature World: With Jack o' Lanterns rotting on our doorsteps and a crisp chill in the air, the last thing you may be worried about is a mosquito bite. However, these pests are still a very real concern some parts of the world. Experts in Brazil have been releasing modified mosquitoes in the thousands for the last few months in a unique effort to fight the spread of a painful disease known as Dengue fever. The fever is rarely fatal, with only about one percent of all infections resulting in severe hemorrhagic...
