Groups in a Brazil town where GMO mosquitoes were released are alarmed at an increase in dengue incidence, leading to a declare of an emergency decree.
Brazilians were promised that the GM mosquitoes would end dengue fever, but results from field trials conducted in Bahia, Brazil were never published and did not evaluate the relation between Aedes aegypti mosquito populations and the occurrence of dengue. According to a Cambridge University study:
“. . . the targeted mosquitoes may simply move to another area and/or a different species of mosquito (Aedes albopictus) which also transmits dengue can move into the area. Complex immune responses to the four types of dengue virus mean that a partial reduction in mosquito numbers can reduce cross-immunity to the different serotypes and increase the number of cases of the severe form of the disease, Dengue Haemorrhagic Fever, which is more likely to be fatal.”
While it is understandable that municipalities with high dengue sickness rates would be interested in lessening the disease, it seems that biotech has once again fooled government agencies into polluting the environment with untested, unsafe, genetically manipulated organisms.
The Brazilian press even lauded the new weapon to combat dengue, but failed to print information that Jacobina’s mayor, a locality where the GMO mosquito trials took place, issued a decree in February 2014 renewing the state of emergency “due to the abnormal situation characterized as a biological disaster of dengue epidemic.”
