An Australian-led project in Indonesia is showing early signs of success in eradicating one of the world's most debilitating viruses â" dengue fever.
- Mosquitos have been infected with a bacteria which renders them incapable of transmitting deng ue fever
- Researchers expect the technology will help significantly reduce dengue cases
- Once established in the population the bacteria is a permanent fix
Transmitted by the Aedes Aegypti mosquito, dengue fever is active in more than 100 countries worldwide, infecting 400 million people every year and killing 25,000.
But scientists from the Eliminate Dengue Fever program in Indonesia believe the virus may have met its match.
"Confident? Of course I'm confident, because the potential of this project is massive," entomologist Warsito Tantowijoyo said.
With technology exported from Melbourne's Monash University, mosquitos in Yogyakarta have been infected with a bacteria called Wolbachia, which renders the insects incapable of carrying and transmitting dengue fever.
So far the Yogyakarta team has released 6 million Wolbachia-infected mosquitos, effectively breeding the disease carrying population out of existenc e.
The team are now gathering the results of the trial.
"In areas where the Wolbachia bacteria has been established, we found that there haven't been any reported cases of local virus transmission," Mr Warsito said.
"We can't say that it will eliminate all cases of dengue. But we expect this technology will significantly contribute to the reduction of dengue cases."
Monash University is the research and development hub of the program and leads the research team.
"All of the evidence is pointing towards success," said Professor Cameron Simmons, director of Impact Assessment at the World Mosquito Program.

The advantage of the Wolbachia bacteria is that, once established in the mosquito population, it's a permanent fix.
"This is a once-and-done application that provides potentially years or even decades of public health protection to that community," Professor Simmons said.
It is also effective against several other deadly mosquito borne diseases, like zika and chikungunya.
"[The trial is] really going to deliver, we hope, the gold standard evidence that [proves] we have a major public health intervention to control these terrible diseases," he said.
The bacteria is now being trialled in 11 other countries, with many more expressing interest.
"The demand is large. We are continually being approached by disease affected countriesâ¦ our challenge is to keep up with that demand," he said.
