A monthlong bout of coronavirus has ravaged China, claiming hundreds of lives and sickening thousands but the Asian influenza also has infected the stock market and other assets, chilling bullish sentiment for the moment and stoking uncertainty at a period of lofty valuations.

Here are some of the assets and sectors that the novel Asian illness has impacted so far, since the infection was noticed Dec. 31.
