Queensland entomologists have detected Ross River virus from a record-breaking number of mosquito samples during the summer season,coinciding with a high number of cases in patients.
From November to April,samples from more than 1225 traps were tested,with a record 116 traps testing positive for the virus – the highest number of positive tests in a single season since the surveillance program began in 2016.
Symptoms of Ross River virus include fever,chills,headache,muscle and joint pains,rash and tiredness.
So far this year,2065 cases have been detected in humans in Queensland – the highest number recorded since the 2019-20 season.
The last time there was a significant Ross River virus outbreak in Queensland was in 2020,when 3381 annual cases were recorded.
Brisbane City Council senior entomologist Darren Alsemgeest said people should protect themselves from mosquito bites,even in the cooler months,including by applying repellent and wearing loose,light-coloured clothing to cover arms,legs and feet.
There is no vaccine or specific antiviral treatment for Ross River virus,and it can be found in more than 40 different species of mosquitoes.
