Bryan Adams tested positive for COVID-19 upon his arrival at Milan's Malpensa Airport on Thursday, just days before the debut of the 2022 Pirelli calendar.
Adams, who is also a photographer, traveled to Milan to promote the Pirelli calendar for 2022, which he shot.
"I've just arrived in Milano and have tested positive for COVID-19 for the second time in a month. So I am headed to the hospital," he wrote in an Instagram post, which included a photo of himself wearing a mask.
Adams, according to a spokesman at the time, is completely immunized and has shown no symptoms.
It's unclear whether the recent positive test is due to so-called coronavirus shedding, which causes persons who have been infected to test positive for a long time after they've been contagious.
Adams was scheduled to attend in-person press events to promote the calendar on Sunday and Monday, but his appearance was now in doubt.
The unveiling of the Pirelli calendar is usually a spectacular event attended by those who appear and other VIPs, but because of the ongoing pandemic, this year's event was already a scaled-back affair, with a small guest list for an evening drink.
Other musical artists such as Cher, Iggy Pop, Jennifer Hudson, Saweetie, and St. Vincent were among Adams' subjects for the "On the Road" calendar.
Adams had a different idea in mind for the 2021 calendar, but it was put on hold because of the virus. When Pirelli asked him to do it again, Adams proposed that the subjects be photographed as though they were on tour.
"What became obvious as a result of COVID-19 was that nobody was working," Adams told the Guardian.
"Because we couldn't do anything else, I recommended to Pirelli that we produce a feature 'on the road,' because that was the one thing we couldn't do," Adams said.
Adams tested positive for COVID-19 before performing at the Rock And Roll Hall Of Fame induction ceremony in Cleveland. During the ceremony, he was supposed to pay tribute to Tina Turner.
Adams has been vaccinated, according to The Los Angeles Times. The leader for the rock band Bon Jovi, Jon Bon Jovi, was also diagnosed with COVID-19, according to the newspaper.
Despite the fact that vaccines are becoming more readily available for countries, they are still in short supply in some parts of the world, with breakthrough cases becoming a common occurrence in the ongoing global health crisis.
