There is a new fear of the COVID-19 pandemic in Paris, three years after the Olympics in Tokyo were hosted under tight security and without fans because of the global outbreak.
The pandemic forced athletes to pull out of games at the Paris Games, while others have resumed wearing masks. However, the influence is far more limited this time.
Numerous athletes, including Australian swimmer Lani Pallister, tested positive.
She had to withdraw from the women's 1500-meter freestyle competition, where she was hoping to win a medal.
However, a representative for the team stated that the decision was taken to conserve Pallister's energy for the 4x200m freestyle relay, which gets underway on Thursday.
Similarly, a day after narrowly missing out on the 100-meter breaststroke gold medal and splitting the silver with American Nic Fink, British swimmer Adam Peaty tested positive.
To give his all in relays later in the week, he has now stated that he will concentrate on a quick, complete recovery.
In the days preceding the opening ceremony, many Australian women's water polo players tested positive for COVID-19, which forced them to withdraw from their teams.
On Tuesday, nevertheless, the team competed and defeated Serbia 8-3.
COVID caused the Tokyo Games to be postponed by a year, but the 2022 Beijing Winter Olympics went forward with extreme caution, making Paris the first Olympics after the pandemic.
Regarding COVID-19, there are no strict rules or regulations in Paris.
According to Mike Wilkinson, the chief medical officer of Canada, his team is still using many of the infection control measures that worked well during the COVID pandemic, such as hand washing, sanitisation, and proper hygiene.
