This one is the worst one. The guy contracted it from a lady who was at training in the company. She contracted it when her parents from Wu-chan visited back in China. The guy has been in contact with 40 people apparently. No idea about the woman. This alone yields huge figures if the spread while in incubation period is confirmed.
