Sept 24 (Reuters) - Copper prices fell on Thursday as the U.S. dollar strengthened and as rising global cases of the novel coronavirus dashed hopes of a quick economic recovery.

The dollar held onto gains, making the greenback-priced metals more expensive for holders of other currencies, as signs of an economic slowdown in Europe and the United States revived fears about the fallout from a second virus wave.

"Metals are under pressure from the stronger dollar," said commodities broker Anna Stablum of Marex Spectron, adding that investors were reducing risk exposure as hopes have faded about more U.S. stimulus ahead of the U.S. presidential election.

"As they (virus cases) are rising again in parts of the United States and Europe, it means the recovery will be slower," she said. The global tally of infections crossed 31.7 million, with deaths at 971,130, as per a Reuters tally.

Three-month copper on the London Metal Exchange fell 0.9% to $6,544 a tonne by 0703 GMT, while the most-traded November copper contract on the Shanghai Futures Exchange declined 1.8% to 50,640 yuan ($7,422.17) a tonne.
