The development of an easy to use, low cost method of detecting dengue virus in mosquitoes based on gold nanoparticles is reported in BioMed Central’s open access journal Virology Journal. The assay is able to detect lower levels of the virus than current tests, and is easy to transport and use in remote regions. Half the world’s population is at risk of Dengue virus infection – it infects 50-100 million people per year, approximately half a million of these require hospitalization and 2.5% (most of which are children) will die. It is one of the most dangerous viruses in the world with no vaccine, and it does not respond to antiviral therapy. The main method of controlling infection remains destruction of the standing water where the mosquitoes, which transmit the virus to people, breed.
