On Tuesday evening, singer My Tam said on her fan page her live show in Hanoi, scheduled to take place in My Dinh National Stadium on May 1, would be postponed due to worries over the Covid-19 pandemic. Tam, having delayed her shows in early March for similar reasons, apologized to those who had bought tickets for her performances in Hanoi this weekend, with 80 percent of the stage already set up.

"Even though our country has contained the pandemic, the situation could become more complicated with the number of new cases in neighboring countries surging, and people entering the country illegally," the singer said in her post, adding the show would be moved to a safer date.

Tam is not the only Vietnamese artist who have had their plans derailed by the looming threat of Covid-19 in Vietnam ahead of the four-day national holiday from Friday to celebrate the Reunification Day (April 30) and Labor Day (May 1).

Over the past few days, the government and health experts have warned Vietnam is at great risk of a new Covid-19 outbreak, especially during the busy coming holiday.

In northern Quang Ninh Province, the May 1 "Tuan Chau - Dao Ngoc Chao He" (Tuan Chau - Pearl Island Says Hello to Summer) show, including many Vietnamese stars, has been canceled due to Covid-19 concerns.

"Since information of the cancellation was only released at the last minute, many cast and crew members had to return home after arriving at the airport. It is sad that many events across the country would be ‘frozen’ this holiday," Hoang Nhat Nam, director of the show, wrote on his Facebook page.

Singer Tuan Hung, scheduled to perform at the show, agreed with the organizers' decision.

"We happily follow the rules for our own safety and that of the community," Hung said.
