MELBOURNE: Fear of ingesting a contaminated substance led Britain`s Emma Raducanu to turn down treatment for an insect bite ahead of the Australian Open.

Raducanu said recent doping cases had made her wary.

`I got really badly bitten by I don`t know what, like ants, mosquitoes, something. I`m allergic, I guess, Raducanu said. `They flared up and swelled up really a lot. Someone was giving me this antiseptic spray, natural, to try to ease the bites. I didn`t want to take it. I was just left there with my swollen ankle and hand. I was like: `I`m just going to tough it out because I don`t want to risk it.` It`s obviously a concern.`-Reuters
