Chris Guy has had 18 COVID-19 tests since the start of the pandemic.
As a high school maths teacher in the Blue Mountains in New South Wales he needs to be vigilant in making sure he monitors his symptoms.
But he knows he doesn’t have the coronavirus.
He has Ross River virus – a mosquito-borne disease that infects roughly 5000 Australians every year.
Mr Guy picked up Ross River virus when he got bitten by a mosquito last April, just as the first wave of the pandemic was starting to take hold in Australia.
