QUT helps China to better predict dengue fever outbreaks

EurekAlert 11 November 2014

Queensland University of Technology (QUT) researchers have found the habit of Googling for an online diagnosis before visiting the doctor can be a powerful predictor of infectious diseases outbreaks.

Now studies by the same Brisbane-based researchers show combining information from monitoring internet search metrics such as Baidu (China’s equivalent of Google), with a web-based infectious disease alert system from reported cases and environmental factors hold the key to improving early warning systems and reducing the deadly effects of dengue fever in China.

Dr Wenbiao Hu, from QUT’s Institute of Health and Biomedical Innovation, have spent more than 20 years working in the area of public health and infectious diseases, and said early detection was vital to reducing the impact of infectious diseases.

What role do insects play in Ebola virus transmission?

(Entomological Society of America 5 November 2014) What role, if any, do insects play in the transmission of Ebola? This question and others will be discussed during a special session at Entomology 2014 — the 62nd Annual Meeting of the Entomological Society of America — in Portland, Oregon at 5:30 PM on Monday, Nov. 17, 2014.

New type of more problematic mosquito-borne illness detected in Brazil

Scientific American 4 November 2014

When a mosquito-borne disease first arrived in the Western Hemisphere last year, humans were relatively lucky. The disease, which causes crippling joint pain persisting for weeks or even months and for which there is no known therapy or vaccine, hopscotched from the Caribbean islands to eventually land in the U.S. and the rest of the Americas. But the type of chikungunya creeping across the region then was one that could only readily spread via Aedes aegypti, a mosquito that is uncommon in the U.S.

Malaria from monkeys now dominant cause of human malaria hospitalizations in Malaysia

(Burness Communications 3 November 2014) The majority of malaria hospitalizations in Malaysia are now caused by a dangerous and potentially deadly monkey-borne parasite once rarely seen in humans, and deforestation is the potential culprit in a growing number of infections that could allow this virulent malaria strain to jump from macaque monkeys to human hosts, according to research presented today at the American Society of Tropical Medicine and Hygiene (ASTMH) Annual Meeting.

Infected mozzies put bite on dengue

Townsville Bulletin SAMANTHA HEALY  October 30, 2014

WELCOME to Ground Zero — a leafy suburban backyard in South Townsville where the fight to eliminate dengue fever will start today.
Eliminate Dengue researchers will place the first container of lab-harvested Wolbachia-infected Aedese aegypti mosquito eggs at this Hubert St house this morning, as part of their city wide trials aimed at eradicating the potentially lethal disease.
Two teams will place containers at about 40 South Townsville properties by the end of the day.
When the eggs hatch, they will release mosquitoes carrying the naturally-occurring Wolbachia bacteria, which prevents the transmission of dengue.
It is hoped the Wolbachia mosquito will breed with wild mosquitoes, and effectively vaccinate the local mosquito population against dengue.

Ebola is not the only, or most dangerous, challenge we face

ON LINE Opinion Peter Curson 28 October 2014

Each day we are confronted by disturbing stories of how Ebola continues to wreck havoc in West Africa and by the threat that it offers to the rest of the world.  In Australia considerable concern has been expressed about the possibility of a returning healthcare worker or tourist transporting the infection to our shores.

But what about the major epidemic of mosquito-borne infectious disease that has been raging through the Pacific Islands over the last two years.

Global infection outbreaks, unique diseases rising since 1980

(Brown University 28 October 2014) Ebola has a lot of company. In a novel database now made publicly available, Brown University researchers found that since 1980 the world has seen an increasing number of infectious disease outbreaks from an increasing number of sources. The good news, however, is that they are affecting a shrinking proportion of the world population.
