Australian doctors claim they have solved the 80-year mystery of how Buruli ulcer spreads from possums to humans after finding “irrefutable evidence” to implicate mosquitoes as the principal vector.

The Doherty Institute–led team in Melbourne — who collected 74,000 mosquitoes across a 350km2 area in Victoria endemic for the necrotising skin disease — says its three-pronged study finally confirms the missing zoonotic link.
