China on Wednesday reported its lowest number of new coronavirus cases since late January, lending weight to a prediction from its senior medical adviser that the outbreak could be over by April.

Global markets took heart from the outlook, but other international experts remain alarmed by the spread of the flu-like virus, which has killed more than 1,100 people, all but two in mainland China, and said optimism could be premature.

China's foremost medical adviser on the outbreak, Zhong Nanshan, said the numbers of new cases were falling in some provinces, and forecast the epidemic would peak this month.
