(NEW YORK) — A pandemic of the novel coronavirus has now killed more than 538,000 people worldwide.

Over 11.6 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 governments are hiding the scope of their nations’ outbreaks.

Since the first cases were detected in China in December, the United States has become the worst-affected country, with more than 2.9 million diagnosed cases and at least 130,306 deaths.

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

5:17 a.m.: Georgia public universities to make face coverings mandatory

The University System of Georgia said Monday it will require everyone to wear face coverings while inside campus facilities and buildings at all 26 of its public institutions where 6 feet of social distancing may not always be possible.

The new policy will take effect July 15 and will be in addition to — not a substitute for — social distancing.

“Face coverings are not required in one’s own dorm room or suite, when alone in an enclosed office or study room, or in campus outdoor settings where social distancing requirements are met,” the University System of Georgia wrote in the updated guidance. “Anyone not using a face covering when required will be asked to wear one or must leave the area. Repeated refusal to comply with the requirement may result in discipline through the applicable conduct code for faculty, staff or students.”

The change comes after more than two-thirds of the Georgia Institute of Technology’s academic faculty protested the school’s plans to reopen this fall without making face masks mandatory.

An open letter to the Board of Regents and the University System of Georgia voiced concerns that the current reopening plans only make masks mandatory for professors, while students are “strongly encouraged” to wear them. The letter, dated July 2, has garnered the signatures of more than 800 professors out of the roughly 1,100 faculty members at the prestigious public university in Atlanta.

4:33 a.m.: Florida teen who died from COVID-19 attended large church gathering

A Florida teenager who died from coronavirus complications last month had attended a large church gathering two weeks earlier, according to a medical examiner’s report.

Carsyn Davis, 17, did not wear a face mask when she attended a church function with about 100 other children on June 10. Social distancing was also not followed, according to the report by the Miami-Dade County Medical Examiner Department.

Three days later, Davis developed symptoms of what her parents thought was a sinus infection

On June 19, Davis’ mother noted that her daughter looked “gray” and tested her oxygen saturation, which was in the 40s. The mother borrowed a home oxygen machine belonging to Davis’ grandfather, and the teen’s levels rose to the 60s. Her parents also gave her a dose of hydroxychloroquine, an anti-malarial drug that President Donald Trump controversially endorsed to treat COVID-19.

Davis’ parents then took her to a local hospital where she tested positive for COVID-19, according to the report.

The parents declined intubation but Davis was given convalescent plasma therapy on June 20 and 21.

Intubation was required on June 22 after Davis’ condition did not improve. She died on June 23, according to the report.

The report notes that Davis had a “complex medical history” and that hypothalamic-pituitary axis dysfunction, morbid obesity and bronchial asthma were all contributory causes to her death.

3:30 a.m.: US reports 45,000 new cases; death toll tops 130,000

More than 130,000 people in the United States have now died from the novel coronavirus, according to a count kept by Johns Hopkins University.

Some 45,000 new cases of COVID-19 were identified across the nation on Monday. The latest daily caseload is lower than the country’s record high of more than 54,000 new cases identified last Thursday.

The national total currently stands at 2,938,624 diagnosed cases with at least 130,306 deaths, 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 cases then hovered around 20,000 for a couple of weeks before shooting back up and crossing 50,000 for the first time last week.

Many states have seen a rise in infections in recent weeks, with some — including Arizona, California and Florida — reporting daily records.
