Challenges and options for disease vector control
نویسنده
چکیده
T he ongoing Zika virus outbreak, which briefly threatened to put a stop to the 2016 Olympic Games in Brazil, has again focused attention on the threat of vector-borne diseases. One efficient strategy to battle such diseases, now underway in Brazil to fight the Zika virus, is to kill the insects that carry the pathogen. Vector control has been practised with varying effectiveness for at least half a century, especially for malaria; the Brazil outbreak again highlights the need for integrating existing methods including the use of insecticides, vaccines, drugs and low technology such as sanitation to keep insect vectors at bay. In addition, new approaches are being developed based on sophisticated methods such as genome editing of the insect vector and deliberate infection of mosquitoes with the Wolbachia bacteria. However, attempts to scale up these new methods from field trials to deployment have been slowed down or halted by environmental concerns or public resistance against genetically modified organisms.
