The rapid spread of the Zika virus has raised interest in a British company that has developed a genetically modified mosquito. Oxitec has produced a genetically engineered line of the Aedes aegypti mosquito, the mosquito that carries dengue fever and chikungunya. Those tropical diseases have become common in Latin America and are now showing up in Florida.
Aedes aegypti also carries Zika, a disease whose symptoms include fever, like dengue. It has also been linked to a birth defect, microcephaly in children born to women infected with Zika.
