Dengue Fever is an infectious tropical disease caused by the dengue virus ans it’s transmitted by several species of mosquito within the genus Aedes, principally A. aegypti.
Researches have described, at the 28th International Congress for Tropical Medicine in Rio de Janeiro (from 24th to 27th Sept.), that a bacterium called Wolbachia pipientis could act as a “vaccine” to the mosquito Aaedes aegypti, blocking the virus multiplication.
When inoculated, the bacterium has shown to decrease the mosquito’s life time. But the team has discovered that it can also block de virus development.
Now a new strain is being used in Australia. It does not decrease the mosquito’s life time, just blocks the virus development.
Mosquitoes are being released in Australia. Next year it will be the turn of Vietnam and Indonesia. In the beginning of 2014 they’ll be released in Rio, the most affected city of Brazil.
