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 5.4 million diagnosed cases and at least 170,052 deaths.Here’s how the news is developing Monday.

O. Combs Unified School District in Arizona’s Pinal County was set to resume in-person classes but notified parents in a letter dated Friday that “we have received a high volume of staff absences for Monday citing health and safety concerns.”“Due to these insufficient staffing levels, schools will not be able to re-open on Monday as planned,” the school district said. “This means that all classes, including virtual learning, will be canceled. At this time, we do not know the duration of these staff absences, and cannot yet confirm when in-person instruction may resume.”The school district added that they “will continue to monitor the situation and will share an update no later than 5:00 p.m. on Monday.”A spokesperson for the school district told Phoenix ABC affiliate KNXV-TV that at least 109 people, including teachers and office staff, have requested not to work.Last week, the head of the Arizona Health Services Department and the state’s superintendent of public instruction laid out a series of guidelines that public schools were urged to use when deciding whether COVID-19 infection rates are low enough to safely reopen for full in-person learning.5:37 a.m.: India’s coronavirus death toll crosses 50,000India’s health ministry recorded 941 additional coronavirus-related deaths in the past 24 hours, bringing the nationwide death toll to 50,921.The country of 1.3 billion people has the world’s fourth-highest death toll from COVID-19, behind the United States, Brazil and Mexico, according to a real-time tally kept by Johns Hopkins University.More than 2.6 million people in India have been diagnosed with COVID-19 since the pandemic began — the third-highest count in the world.4:29 a.m.: Another school closes its doors in Georgia amid rising casesA third school in Georgia’s Cherokee County is shuttering due to a growing cluster of coronavirus cases among its students and staff.The Cherokee County School District announced Sunday that it was temporarily closing Creekview High School in Canton, Georgia, with the hope of resuming in-person classes there on Aug. 31.“Over this weekend, the number of positive cases at Creekview High School has increased to a total of 25, with 500 of its 1,800 in-person students now under precautionary quarantine, and additional tests pending that would significantly increase the quarantine total,” the Cherokee County School District said in a statement. “We understand these closings create hardships and are disappointing to students who want to learn in-person as well as their families, but these are necessary measures to avoid potential spread within our schools.”The school district has also temporarily closed in-person learning at Woodstock High School and Etowah High School, where reopening is also tentatively scheduled for Aug. 31. Remote learning will be in effect for all students at the three schools in the meantime.Cherokee County reopened its schools on Aug. 3, welcoming back 30,000 students for in-person learning.

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.An internal memo from the Federal Emergency Management Agency, obtained by ABC News on Sunday night, shows that the nationwide number of new cases over the last week has continued to decrease in week-over-week comparisons, while the number of new deaths has reversed and gone up.
