Security personnel keep watch outside the Wuhan Institute of Virology in Wuhan, Hubei province, Chin

* Chinese foreign ministry denies that staff fell ill * Report may boost calls for wider probe into origins * Article published on eve of key WHO meeting   Three researchers from China's Wuhan Institute of Virology (WIV) sought hospital care in November 2019, a month before China reported the first cases of Covid-19, the Wall Street Journal reported on Sunday, citing a US intelligence report. The newspaper said the previously undisclosed report - which provides fresh details on the number of researchers affected, the timing of their illnesses, and their hospital visits - may add weight to calls for a broader investigation into whether the Covid-19 virus could have escaped from the labouratory.
