Mosquitoes contaminated with a ‘miraculous’ micro organism have been proven to scale back dengue fever circumstances by 77%, in a groundbreaking new examine.

Scientists launched mosquitoes contaminated with ‘Wolbachia’ micro organism into the Indonesian metropolis of Yogyakarta – however solely in sure zones.

In the zones the place the modified mosquitoes had been launched, circumstances of dengue fell by 77% and hospitalisations dropped by 86%.

The outcomes of the examine, carried out by the World Mosquito Programme (WMP), had been ‘better than we could have hoped for’, based on researcher Dr. Katie Anders.

Cases of dengue fever, a virus that may trigger muscle and bone ache, and demise, have risen quickly up to now many years – there are an estimated 400 million circumstances a 12 months.

The Wolbachia micro organism used within the trial had been chosen as a result of it hides in the identical components of a mosquito’s physique that dengue virus hides in.

A micro organism that’s benign to people, the Wolbachia then competes for sources with the dengue virus, which makes it much less probably for the mosquito to trigger a dengue an infection when it bites a human.

Researchers launched 5 million mosquito eggs over a interval of 9 months in buckets of water in Yogyakarta metropolis, in 12 separate zones.

The outcomes of the examine had been so profitable that the modified mosquitoes have now been launched into the remainder of the town, with the WMP now shifting into surrounding areas to attempt to eradicate dengue within the area.

‘This trial result shows the significant impact the Wolbachia method can have in reducing dengue in urban populations,’ mentioned professor Cameron Simmons, who helped lead the examine.

‘This result demonstrates what an exciting breakthrough Wolbachia can be – a safe, durable and efficacious new product class for dengue control is just what the global community needs.’

The Wolbachia bacterium can also be in a position to manipulate mosquito fertility to make sure it’s handed all the way down to future mosquito generations, hopefully eradicating dengue in years to return, in contrast to pesticides or sterilising male mosquitoes, which must be carried out recurrently to suppress the bugs.

Some illness modelling research have proven that Wolbachia might be sufficient to fully suppress dengue fever, if efficiently established in mosquito populations.

Scientists additionally hope that the identical technique might be utilized to different illnesses that inhabit related components of the mosquito’s physique, like Zika, yellow fever and chikungunya.

‘This is the result we’ve been ready for,’ mentioned WMP program director Scott O’Neill.

‘We have evidence our Wolbachia method is safe, sustainable and dramatically reduces incidence of dengue.’

‘It gives us great confidence in the positive impact this method will have worldwide when provided to communities at risk of these mosquito-transmitted diseases.’
