That case was mentioned in a popular paper with about 8 others I recall. One big issue is that they all occured pretty early on when testing wasn't so wide spread. So there's also a good chance it was just a concidence and they were actually exposed to someone else. This is one issue with the media. That paper, with less than 10 case reports of asymptomatic and potential airborne spread was spread much more rapidly than the WHO report which reviewed ~70k Chinese cases and most spread within household contacts.
