The 26-year-old plans to play in Kitzbuehel in western Austria in an exhibition event he is co-organising next and then in Berlin, after which he said he would do "intensive training" to prepare for Cincinnati and the US Open if those go ahead.
He played in the Adria Tour exhibition tournament organised by Novak Djokovic last month after which the world No 1 and three other participants all tested positive for the new coronavirus.
The matches, where social distancing was minimal, were played in front of thousands of fans, while the players were seen partying at a packed Belgrade night spot, earning a storm of criticism.
Thiem, who has tested negative for the new coronavirus since Belgrade, reiterated in the ORF interview the "huge mistake by us all".
"We all acted much too euphoric. The most important is that we learn from our mistakes," he said.
