Wall Street dips at the opening

US stock indices fell on Monday as the week opened up amid ongoing concerns about China.

Health authorities reported tens of thousands of new infections in China, leading to renewed shutdowns in multiple cities including Shanghai. 

China is the world's largest importer and consumer of industrial metals and commodities, and due to restrictions, its economy is expected to suffer. 

Dow Jones fell 0.5% as of 15:43 GMT to 180 points to 34,158, while S&P 500 shed 0.7%, or 28 points to 3,998, as NASDAQ slipped 0.7%, or 75 points to 11,151.
