The world passed another grim milestone in the coronavirus pandemic on Friday.
U.S. COVID-19 cases reached 20 million on January 1, and the number since then has increased by 1 million every four days.
The US is the worst-hit country with the world's highest number of cases and deaths at 23,308,712 and 388,529, respectively, according to the CSSE.
The worldwide coronavirus death toll surpassed 2 million on Friday, according to a Reuters tally, as nations around the world are trying to procure multiple vaccines and detect new COVID-19 variants.
There have been almost 100 million infections globally. It took almost nine months for the disease to take the first one million lives.
Covid-19 took the same time to take two million lives, according to official records. It has doubled in less than four months.
The other countries with more than a million confirmed cases are Brazil (8,195,637), Russian Federation (3,412,390), the United Kingdom (3,173,274), France (2,864,360), Turkey (2,346,285), Italy (2,303,263), Spain (2,137,220), Germany (1,957,898), Colombia (1,816,082), Argentina (1,744,704), Mexico (1,556,028), Poland (1,395,779), Iran (1,299,022), South Africa (1,259,748), Ukraine (1,160,243) and Peru (1,037,350), the CSSE figures showed.
And the mounting cases and deaths have yet to slow despite the rollout of two coronavirus vaccines. Data from the states and the U.S. Centers for Disease Control and Prevention shows that less than 2% of the population in Alabama, Georgia, Mississippi and SC had received its first dose of a vaccine at the start of this week.
In the US, the vaccine rollout has been slow, with just 11.1 million doses administered out of the 30.6 million distributed.
President-elect Joe Biden has set a goal of administering 100 million doses in his first 100 days in office.
