"The situation as we said in the beginning, we were controlling the cases, there were some in Austria, and then in any place there've been one or two people who've been home and then have some problems before they return - some riders and some workers in the paddock.
But the most important thing is that, through the tests we were doing, we were able to control everything and know what the situation is," Ezpeleta added.
On the track Mir and Suzuki created history. The Spaniard's victory has many firsts to its credit. He became the first Moto3 champion to win the premier class title and the first to win it for Suzuki in 20 years since Kenny Roberts Jr in 2000.
He is also the first former Red Bull MotoGP Rookies Cup rider to win the premier class crown.
It was a forgettable season for six-time champion Marc Marquez. The Spaniard's hopes of a fifth straight title were all but ended by the injury suffered in season opener at Jerez when he fell off his bike while in the lead.
The 27-year-old, who has been out of action since July, possibly faces another six months on the sidelines after undergoing a third surgery on his right arm.
The MotoGP 2021 grid will miss two of the regular riders, who have been in the paddock for many years -- Andrea Dovizioso and Cal Crutchlow.
Italian rider Dovizioso, who competes for Ducati is taking a planned sabbatical in 2021 and stepping away from competition while Britishman Crutchlow of LCR Honda is preparing to change racing for testing.
