How can she have been patient zero if other people before her had matching symptoms?
EDIT: It does actually say later in the article she might not really be patient zero. Which means they haven't found patient zero at all yet, just 27 people who got it really early.

The names of the alleged “patient zero”, Wei Guixian, is followed by “as identified by The Wall Street Journal”, so I searched for “Wei Guixian site:wsj.com”, and the only result was a March 6 article: https://www.wsj.com/articles/how-it-all-started-chinas-early... which, not surprisingly, is paywalled. So what has changed since March 6 that warrants this news article? The article doesn’t seem to point to any new research.
