New Trial Eradicated 80% of a Disease-Carrying Mosquito Population
A new trial experiment undertaken in Australia has been shown to successfully eliminate 80% of the disease-bearing mosquito Aedes aegypti.
Why is Aedes so good at being a vector?
Seeing the Zika virus epidemic in South America it is hard to believe that just 50 years ago the Aedes mosquitoes that spread it and several other tropical diseases were nearly eliminated in that region. Ever since then it seems we have been going backwards in mosquito control. Aedes aegypti seems to be adapted to…
How effective are current measures for protecting horses from African Horse Sickness?
By Miroslav Djuric, DVM, CAB International, Wallingford, UK. African horse sickness is a serious and often fatal disease of horses, mules and donkeys caused by African horse sickness virus (AHSV), of the genus Orbivirus in the family Reoviridae. It can also affect zebras, camels and dogs, but not humans. Zebras and donkeys rarely develop serious…
Dengue situation in a Southern Indian state (Andhra Pradesh) – Gaps and opportunities in Community Awareness
Dengue is the fastest growing vector-borne disease worldwide, and reported cases in the Southern Indian state Andra Pradesh have steadily risen from 313 in 2008 to 2299 in 2012. The many missed cases due to partial reporting by private hospitals and clinics in this state, increased urbanisation and lack of people participation in health issues, makes one sceptical of the true burden of this potentially deadly disease. A community physician in Hyderabad summarises knowledge and practice on community awareness of dengue in Andra Pradesh, and looks at strategies to make information & communication a priority for addressing know-do gaps.
The 2014 World Health Day focuses on Vector-Borne diseases
For World Health Day April 7th 2014, CABI's "Handpicked" features blogs from regions where vector-borne diseases daily kill or debilitate. In “The 2014 World Health Day focuses on Vector-Borne diseases”, Joseph Ana, editor of BMJ West Africa and former Commissioner for Health, Cross River State, Nigeria, makes the case for information dissemination & regional cooperation on vector-borne diseases. Drawing on personal experience, he highlights the need to support low-and-middle-income countries (LMICs) where good public health practice has significantly reduced vector borne diseases, & to actively extend their best practice to other regions lagging behind.
Malaria can climb mountains when temperatures rise
A study in Science by Siraj and colleagues this week showed malaria occurs at higher altitudes in warmer years. Their modelling predicts that a one degree Celsius temperature rise in the Ethiopian highlands could lead to 2.8 million more cases in children each year in current malaria areas and over 400,000 cases in new areas.…
Climate change – will it affect spread of vector borne diseases?
Climate change is going to mean mosquito-borne diseases spread north out of the tropics right? That seems to be the story the news media are giving us. But it is really the case? Do we really need to start thinking about buying bednets to protect against mozzy bites? As editor of Global Health database I…
Chikungunya conquers the Swiss Alps
Earlier this week, a mosquito (Aedes albopictus) that can carry chikungunya and dengue fever viruses has been spotted north of the Swiss Alps in the canton of Aargau. In response, the Swiss health ministry plans to make chikungunya, which was described for the first time in Tanzania in 1952, a mandatory reportable disease from next…
