TOKYO (Reuters) - The Tokyo Olympics may have to be postponed again if the novel coronavirus mutates into a stronger pathogen, Kiyoshi Kurokawa, a prominent Japanese government adviser, said on Wednesday.

However, a recent spike in cases in Tokyo is due to a failure to stick to guidelines to prevent contagion, he said.
