(NEW YORK) — The novel coronavirus has now killed more than 749,000 people worldwide.

Over 20.6 million people across the globe have been diagnosed with COVID-19, the disease caused by the new respiratory virus, according to data compiled by the Center for Systems Science and Engineering at Johns Hopkins University. The actual numbers are believed to be much higher due to testing shortages, many unreported cases and suspicions that some national governments are hiding or downplaying the scope of their outbreaks.

Since the first cases were detected in China in December, the United States has become the worst-affected country, with more than 5.1 million diagnosed cases and at least 166,027 deaths.

Here’s how the news is developing Thursday. All times Eastern:

6:39 a.m.: India reports highest single-day spike in infections

India registered 66,999 new cases of COVID-19 in the last 24 hours, its highest single-day spike in infections yet.

The country also recorded an additional 942 coronavirus-related fatalities, according to the Indian Ministry of Health and Family Welfare.

The nationwide total now stands at just under 2.4 million confirmed cases with at least 47,033 deaths. More than 653,000 of those cases remain active, after 1.6 million patients have recovered.

India has the third-highest number of diagnosed cases in the world, after the United States and Brazil.

5:12 a.m.: Newborn baby among Minnesota children recently hospitalized

A newborn baby is among the children recently hospitalized with COVID-19 in Minnesota, according to a report by Saint Paul ABC affiliate KSTP-TV.

Jenni Gibbens said her son, Harrison, was just 25 days old when he tested positive for COVID-19 and was hospitalized in July, making him one of Minnesota’s youngest coronavirus patients.

“I was in absolute shock,” Gibbens told KSTP. “Any time when it’s your child, it’s just heartbreaking.”

Gibbens’ entire family ended up contracting the virus, with her husband being the first to show symptoms in early July. Her 4-year-old son Deacon, who also tested positive, was asymptomatic, she said.

Baby Harrison spent three days at Children’s Minnesota hospital, where staff monitored his fever, oxygen levels and heart function.

“At 27 days old, he is officially taking the title of a COVID survivor, which seems unreal,” Gibbens told KSTP.

To date, more than 9,000 Minnesota residents under the age of 20 have tested positive for COVID019, including more than 1,400 children younger than 6, according to KSTP.

Patsy Stinchfield, a pediatric nurse practitioner and the senior director of infection prevention and control at Children’s Minnesota, said 72 children have been admitted to the hospital with COVID-19, with around 10 needing to be put on ventilators.

“Most of the kids that are coming in are in for support, IV fluids, observation, just making sure they’re not going to get worse,” she told KSTP. “We are seeing a very wide variety of symptoms.”

4:48 a.m.: Italy orders COVID-19 tests for travelers from four nations

Italy has ruled that people traveling to the country from Croatia, Greece, Malta and Spain must be tested for COVID-19 on arrival.

Italian Health Minister Roberto Speranza announced Wednesday evening that he had signed the new order, adding that anyone traveling from or through Colombia would be barred from entering Italy.

“We must continue along the line of prudence to defend the results achieved in recent months with everyone’s sacrifice,” Speranza wrote in a Facebook post.

Italy, once the epicenter of the coronavirus pandemic in Europe, has so far reported more than 251,000 diagnosed cases of COVID-19 with over 35,000 deaths. The country has largely contained the spread of the virus in recent months, but now there are fears of a possible resurgence of infections.

Italy registered another rise in the number of new infections Wednesday, with 481 cases identified in the past 24 hours — up from 412 on Tuesday, according to data released by the Civil Protection Agency.

3:50 a.m.: US records nearly 56,000 new cases, over 1,500 additional deaths

There were 55,910 new cases of COVID-19 identified in the United States on Wednesday, according to a count kept by Johns Hopkins University.

An additional 1,504 coronavirus-related deaths were also reported — a jump of more than 400 from the previous day.

It’s the first time in four days that the nation has recorded over 50,000 new cases. But Wednesday’s caseload is still well below the record set on July 16, when more than 77,000 new cases were identified in a 24-hour reporting period.

A total of 5,197,377 people in the U.S. have been diagnosed with COVID-19 since the pandemic began, and at least 166,027 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.

Many states have seen a rise in infections in recent weeks, with some — including Arizona, California and Florida — reporting daily records. However, the nationwide number of new cases and deaths in the last week have both decreased in week-over-week comparisons, according to an internal memo from the Federal Emergency Management Agency obtained by ABC News Wednesday night.
