Estec Vina at the Vietnam Singapore Industrial Park (VSIP) 1 has recorded over 340 cases since July 19, though its workers have been staying in the premises since July 19. Truong Hung Dung, head of the company’s labor union, said the entire workforce of 1,700 was supposed to be tested on July 19, but health authorities were only able to dispatch personnel four days later, and by that time 136 people had already contracted the infection.
