South Korea is taking no chances with the health of its athletes competing at the Rio de Janeiro Olympic Games, issuing them with uniforms that have been infused with insect repellent to keep mosquitoes carrying the Zika virus at bay.

The South Korean team's uniforms were unveiled in Seoul on Wednesday, marking 100 days until the opening ceremony in Brazil.

The formal uniforms, which the Korean Olympic Committee said will be worn during ceremonies and at the athletes' village, feature long trousers and long-sleeved shirts under a blazer that have all been treated with the repellent.
