Coronavirus latest: 94% of COVID deaths in US had underlying conditions, CDC says

Hungary will shut its border to non-residents from Tuesday in an effort to curb the rising number of COVID-19 cases, the country’s government announced Friday.

Meanwhile, Hungarian citizens returning home from abroad will be required to either self-quarantine for 14 days or test negative for COVID-19 twice, within 48 hours apart.

The move comes after Hungary identified 292 new cases on Sunday, the largest day-to-day increase the landlocked European nation has seen so far.

Overall, Hungary has reported at least 6,139 diagnosed cases of COVID-19 with 615 deaths, according to a count kept by Johns Hopkins University.

There were 35,343 new cases of COVID-19 identified in the United States on Sunday, according to a count kept by Johns Hopkins University.

Sunday’s tally is far below the country's record set on July 16, when 77,255 new cases were identified in a 24-hour reporting period.

An additional 429 coronavirus-related deaths were also recorded Sunday. The latest daily death toll is well under the record 2,666 new fatalities that were reported on April 17.

A total of 5,997,163 people in the United States have been diagnosed with COVID-19 since the pandemic began, and at least 183,068 of them have died, according to Johns Hopkins. The cases include people from all 50 U.S. states, Washington, D.C. and other U.S. territories as well as repatriated citizens.

By May 20, all U.S. states had begun lifting stay-at-home orders and other restrictions put in place to curb the spread of the novel coronavirus. The day-to-day increase in the country's cases then hovered around 20,000 for a couple of weeks before shooting back up and crossing 70,000 for the first time in mid-July.

However, the numbers of new COVID-19 cases and new deaths in the United States have both decreased by substantial amounts in week-over-week comparisons, according to an internal memo from the Federal Emergency Management Agency obtained by ABC News last week.

The U.S. Centers for Disease Control and Prevention has released information showing how many people who died from COVID-19 as of last week had underlying health conditions and contributing causes.

“For 6% of the deaths, COVID-19 was the only cause mentioned,” the CDC stated on its website, alongside the data. “For deaths with conditions or causes in addition to COVID-19, on average, there were 2.6 additional conditions or cases per death.”

According to the CDC, some of the most common underlying conditions and contributing causes linked with COVID-19 deaths were influenza and pneumonia; adult respiratory distress syndrome, respiratory failure; hypertensive disease; cardiac arrest; heart failure; sepsis; diabetes; vascular and unspecified dementia; renal failure; and intentional and unintentional injury, poisoning and other adverse events.

The worldwide number of diagnosed cases of COVID-19 is now at 25,236,271, according to a real-time count kept by Johns Hopkins University.

At least 846,574 people around the globe have died from the disease.

The top five countries with the highest national tallies of cases are the United States, Brazil, India, Russia and Peru, respectively.

The United States alone accounts for more than 23% of the world’s diagnosed cases.
