Increasing number of horses succumbing to Ross River virus

ABC News Courtney Wilson 17 May 2015

A surge in mosquito numbers in south-east Queensland is posing health risks for horses, as well as humans.

The recent spike in the number of people contracting Ross River virus has been well documented, but that the virus can also affect horses is relatively unknown.

Brisbane City Council banks cash set aside for mosquito spraying despite Ross River fever outbreak

The Courier Mail Matthew Killoran May 15, 2015

WHILE the city battles maddening mozzies and a Ross River fever outbreak, the Brisbane City Council has left almost $40,000 in its kitty for spraying against the buzzing pests.
The council says it has conducted a record number of mosquito sprays this year, but its Labor Opposition argues it did not make sense to leave money unspent in the battle against the mozzies.
More than 4640 cases of Ross River fever have been reported in Brisbane this year. While the council has $3.5 million set aside each year for mosquito spraying, the third budget review has revealed a $39,000 decrease in expenses, listed as being due to savings.
Labor lord mayoral candidate Rod Harding said it had been a huge mosquito season and more needed to be done.
“I don’t understand why you would bank $39,000 when it’s one of the worst Ross River virus outbreaks in 20 years,” he said. “There’s so much more they could be doing. Why not use that money on more spraying or educating people about the risks of Ross River virus?”
But Lord Mayor Graham Quirk said $3.2 million out of the $3.5 million mozzie-battling budget had already been spent spraying 21,000ha, with ground crews tackling 75,000 sites, up from 64,000.
“The $39,000 saving identified in the budget review process is due to lower-than-anticipated overhead costs during the last quarter, including fuel and chemicals, and only represents around 1 per cent of the program budget,” Cr Quirk said.
“These funds will go back into council’s budget and this won’t impact operations on the ground. We are the only local government to employ two medical entomologists and we conduct sprays when it is ­needed, based on the science behind it.”
The council undertook a mass mosquito spray following the freak storm on May 1 in which 181mm fell on parts of the city within a few hours.
Higher-than-average rainfall combined with high tides during the summer provided ideal breeding conditions for mosquitoes.

New Malaria Test Could Lead to Global Eradication of the Disease

PR Newswire | May 11, 2015

One of the biggest difficulties faced by worldwide programs aimed at eliminating malaria is that the tests they use are not sensitive enough to detect all people who have the disease and need treatment. A study appearing online today in Clinical Chemistry, the journal of AACC, shows that a new test known as capture and ligation probe-PCR (CLIP-PCR) could diagnose the malaria cases that would typically escape detection and lead to new infections.  Continue reading…

WSU ecologist warns of bamboo fueling spread of hantavirus
