US President Joe Biden is pushing harder on vaccines and masks as COVID-19 cases are surging across the country due to the spread of the highly contagious Delta variant.

Iran PressAmerica: Joe Biden tweeted on Saturday that the Delta variant is on the rise in the United States and called for faster nationwide vaccinations.

Anthony Fauci said last Sunday that the situation in the United States is deteriorating in terms of coronavirus infection due to the outbreak of the delta variant.

According to US media reports, the new Biden administration is taking action as the number of patients hospitalized with Covid-19 and the death toll associated with it is rapidly increasing in the United States.

Many Americans refuse to get the jab in the belief that the side effects will be worse than COVID-19 itself. Others believe conspiracy theories about the vaccines, which are widely circulated on social media.

As of Friday, 50 percent of the U.S. population - more than 165.9 million people - had been fully vaccinated against COVID-19, according to the CDC.

The United States is now averaging 100,000 new COVID-19 infections per day, returning to a milestone last seen during the winter surge as health officials urge people to get vaccinated to stem a surging spread of the Delta variant.

The US now has the highest coronavirus-related death toll in the world. 219
