COVID-19 updates: Anti-vaccine protesters halt vaccinations at Dodger Stadium

The United States is seeing improvements in COVID-19 infections and hospitalizations. In the last two weeks, the country's seven-day average of new COVID-19 cases has declined by 33.1%, according to ABC News' analysis of data compiled by The COVID Tracking Project, a volunteer-run effort to track the U.S. outbreak.

On Monday, Missouri reported the fewest number of new cases since September, while South Dakota reported the lowest number of new cases since July.

COVID-19 hospitalizations are also declining nationwide. The COVID Tracking Project said the number of people hospitalized with the disease in the U.S. is currently at its lowest since Dec. 14.

Hospitalizations are even trending down in California, which has more COVID-19 patients in hospitals than any other U.S. state.

Colombian President Ivan Duque announced Tuesday that Defense Minister Carlos Holmes Trujilo died in the early morning hours from COVID-19 complications. He was 69.

"I can't express the pain that I have," Duque said in a statement while conveying his condolences to Trujilo's family.

Colombia has the third-highest number of confirmed COVID-19 cases in the Americas, behind the United States and Brazil, according to the World Health Organization.

Europe's longest land border, spanning more than 1,000 miles, has closed for the first time since World War II.

Sweden's temporary ban on entry from neighboring Norway went into effect Monday and will last until at least Feb. 14. The Swedish government has also extended an entry ban from the United Kingdom and Denmark until the same date.

The move comes amid concerns over a new, more contagious variant of the novel coronavirus that was first identified in the U.K. and has since spread to Norway's capital and the surrounding area.

On Saturday, shortly before Sweden announced the new travel ban, the Norwegian government imposed strict new lockdown measures for Oslo and nine neighboring municipalities due to an outbreak of the variant.

South African President Cyril Ramaphosa has accused wealthy countries of "hoarding" excess doses of COVID-19 vaccines that they had ordered but did not immediately need.

Without identifying specific countries, Ramaphosa asserted that rich nations had "acquired large doses of vaccines" -- some "up to four times what their population needs" -- with the aim of "hoarding" them and "to the exclusion of other countries in the world that most need this." He said ending the global pandemic "will require greater collaboration on the rollout of vaccines, ensuring that no country is left behind in this effort."

"We need those who have hoarded the vaccines to release the vaccines so that other countries can have them," Ramaphosa told a virtual meeting of the World Economic Forum on Tuesday. "We are all not safe if some countries are vaccinating their people and other countries are not."

Ramaphosa's comments come as African nations grapple with a rising number of COVID-19 infections. South Africa accounts for nearly half of the continent's confirmed cases and deaths from the disease, according to the latest data from the Africa Centers for Disease Control and Prevention.

Ramaphosa chairs the African Union, which secured a provisional 270 million COVID-19 vaccine doses from manufacturers last week for its 55 member states across the continent. Ramaphosa said those doses will supplement the 600 million to be acquired from the COVAX Facility, a global initiative co-led by the World Health Organization to ensure rapid and equitable access to COVID-19 vaccines for all countries regardless of income.
