A shrimp peddler at the Chinese market where the coronavirus pandemic likely began has been identified as one of the first victims of the disease — and possibly “patient zero.”

The 57-year-old woman, identified by the Wall Street Journal as Wei Guixian, was the first person from the now-notorious Huanan market in Wuhan to test positive for the deadly bug.

She was at work Dec. 10 when she developed what she thought were cold symptoms, Chinese outlet The Paper reported. So she walked to a small local clinic for treatment and then went back to work — likely spreading the contagion.
