WASHINGTON (Reuters) - The United States is closely watching the more infectious variant of COVID-19 after British officials warned that it may also be more deadly, U.S. National Institutes of Health Director Francis Collins said on Saturday.

But U.S. health officials are somewhat more worried about a separate variant from South Africa, although that one has not yet been identified among U.S. cases of the novel coronavirus , he told MSNBC in an interview.

Collins noted the UK's data was preliminary, and said it was unclear why those with the UK variant faced a higher risk of death, whether by changes in the virus itself or other external causes such as pressures on the healthcare system.

"Let's take this as something to watch closely," he said.

Collins' comments come as Democratic President Joe Biden takes the reins of the nation's COVID-19 response, seeking to re-energize the fight against the highly infectious disease and urging a war-like stance. In a flurry of actions since taking office Wednesday, Biden unveiled a new U.S. strategic plan to curtail the outbreak and signed numerous executive orders to boost vaccines and increase mask use, among other measures.

The United States is the nation hardest-hit by COVID-19 , with 24.70 million cases and 413,775 deaths by midnight Friday. Over the past week, 3,089 Americans have died of the disease on average, while 20 U.S. states reported record deaths this month.

British Prime Minister Boris Johnson on Friday warned that the UK variant was associated with higher level of mortality but said vaccines still appeared effective against it.

The U.S. Centers for Disease Control and Prevention last week warned the UK variant, already circulating in at least 10 U.S. states, could become the dominant variant in the United States by March. The variant, known as B.1.1.7, is believed to be twice as contagious as the current version circulating across the United States.

Despite a subtle difference in the data, Collins said it showed current vaccines would still be very protective against the UK variant, so "at the moment we are not alarmed about that," Collins said.

"We are somewhat more concerned about a South African variant" that appears to be somewhat less protected against by vaccines, he said. No known cases, however, have been found in the United States yet, he added.

Scientist on Wednesday said the South African variant may reduce the efficacy of current vaccines, which also raises the prospect of re-infection.

The United Kingdom has banned travelers from some African countries in an attempt to stop the spread of that strain in the British Isles and is weighing further restrictions.

Biden has moved to impose a mandatory quarantine for air passengers arriving in the United States, although details have not yet been released. He is also requiring U.S.-bound passengers to have a negative COVID-19 test starting on Tuesday.

Thyssenkrupp ends talks with UK's Liberty on steel unit sale

By Christoph Steitz, Tom Käckenhoff and Arno Schuetze FRANKFURT (Reuters) - German conglomerate Thyssenkrupp ended talks to sell its steel division to Britain's Liberty Steel due to differences over value, the latest setback in efforts to consolidate the European sector. Liberty Steel, led by commodities tycoon Sanjeev Gupta, last month submitted a firmed-up non-binding bid for Thyssenkrupp's steel unit, Europe's second biggest in terms of sales, which sources said included commitments to protect jobs and sites.
