Nov 13 (Reuters) - Gold prices were little changed on Friday, as fears of an economic impact due to a surge in global cases of COVID-19 countered optimism from the developments in a potential vaccine. FUNDAMENTALS * Spot gold was steady at $1,876.92 per ounce by 0044 GMT. It was headed for its worst weekly performance since late-September, declining 3.8% so far. * U.S. gold futures were up 0.1% at $1,874.50. * The dollar index held steady but was on track for a 0.7% weekly gain. * The heads of the Federal Reserve and the European Central Bank welcomed the encouraging results in trials of a vaccine candidate for COVID-19 but stressed that the economic outlook will remain uncertain. * The number of Americans filing new claims for unemployment benefits fell to a seven-month low last week, but the pace of decline has slowed and further improvement could be limited by higher infections and lack of additional fiscal stimulus. * Top Democrats in U.S. Congress urged renewed negotiations over a multitrillion-dollar coronavirus aid proposal, but a top Republican immediately rejected their approach as too expensive. * European officials warned against COVID-19 complacency and said measures to control a surge in infections must continue. * More than a dozen U.S. states have doubled their COVID-19 case loads in the last 14 days, compared with the previous two-week period, while the global tally has crossed 52.45 million. * The London Bullion Market Association is threatening to stop bullion from countries including the United Arab Emirates entering the mainstream market if they fail to meet regulatory standards, a letter seen by Reuters showed. * Silver rose 0.1% to $24.26 per ounce.
