The United States is facing a COVID-19 surge this summer as the more contagious delta variant spreads.

More than 613,000 Americans have died from COVID-19 and over 4.2 million people have died worldwide, according to real-time data compiled by the Center for Systems Science and Engineering at Johns Hopkins University.

Just 57.9% of Americans ages 12 and up are fully vaccinated against COVID-19, according to data from the Centers for Disease Control and Prevention.

The CDC on Tuesday, citing new science on the transmissibility of the delta variant, changed its mask guidance to now recommend everyone in areas with substantial or high levels of transmission -- vaccinated or not -- wear a face covering in public, indoor settings.

US not lifting travel restrictions due to surge in delta variant cases

The White House will leave in place existing travel restrictions due to the surge in cases from the delta variant, a White House official confirmed to ABC News.

This news was first reported by Reuters Monday morning.

The official said the "reopening process is guided by the science and public health," adding that cases of the delta variant are rising in the U.S. and globally, mostly among the unvaccinated, and "appear likely to continue [to] increase in the weeks ahead."

Symptomatic breakthrough infections rare, CDC data estimates

New data shows how rare COVID-19 breakthrough infections likely are.

With more than 156 million Americans fully vaccinated, about 153,000 symptomatic breakthrough cases are estimated to have occurred as of last week, representing approximately 0.098% of those fully vaccinated, according to an unpublished internal Centers for Disease Control and Prevention document obtained by ABC News. These estimates reflect only the adult population and do not include asymptomatic breakthrough infections.

But in Provincetown, on Massachusetts’ Cape Cod, at least 551 COVID-19 infections, many of them breakthroughs, were confirmed after the July Fourth weekend. Of the Massachusetts residents who tested positive as a result of the Provincetown cluster, 69% reported to be fully vaccinated, according to local officials.

Most people were symptomatic. Apart from three hospitalizations, symptoms from cases associated with this cluster were known to be mild and without complication, said Alex Morse, the town manager for Provincetown.
