Fighting Dengue Fever With Genetically Modified Mosquitoes

With the ongoing Dengue fever outbreak in Singapore I wonder if they are thinking of experimenting with this option. The video was created by the Wellcome Trust (a UK based non-profit medical research organization) on this effort to fight the Dengue virus.

Oxitec is experimenting with genetically modified male mosquitoes that are infertile. So when they mate no offspring are born. They are able to target the specific mosquitoes that carry dengue (because those mosquitoes are genetically distinct from other mosquitoes).

From Oxitec’s Dengue Information Center:

Dengue fever is the fastest growing mosquito-borne disease, affecting over 50 million people each year across the world, and continuing to grow both in prevalence and severity.

There are around 25,000 fatalities each year and severe cases require hospitalisation and constant monitoring. Dengue is an extremely expensive disease, estimated to cost the global economy over US$5 billion per year.

Dengue is caused by four different, but related, viruses (known as DENV-1,2,3 and 4). Once infected, a person can develop a lifelong immunity to that strain of the virus but can become more susceptible to the other three strains.

Singapore Science Museum

The Science Center in Singapore is focused on providing kids interactive exhibits with science content. It is worth a visit if you like such museums, it is a bit above average for such museums, in my experience. They have the expected IMAX theatre (which has assigned seats – I didn’t notice this until someone made us move).

As is the case with many exhibits at these types of museums sometimes it seems like they just make something interactive without making it very educational. The skeleton was that way (also people had trouble making it work, making the movements necessary to get it to respond).
