Over 14.8 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 or downplaying the scope of their nations' outbreaks.
The United States has become the worst-affected country, with more than 3.8 million diagnosed cases and at least 141,845 deaths.

7:48 p.m.: Los Angeles says most new cases are in people below age 41
Younger people are continuing to drive new COVID-19 infections in Los Angeles County, health department officials said.
The county reported 2,741 new cases of COVID-19 on Tuesday, of which 57% were people under age 41.
However an overwhelming majority of all deaths -- nearly 75% -- are in people over the age of 65, Director of Public Health Barbara Ferrer said. That age group accounts for 11% of all cases.
"The tragedy of what we are witnessing is that many of our younger residents are interacting with each other and not adhering to the recommended prevention measures, while our older residents continue to experience the results of this increased spread with the worst health outcomes, including death," Ferrer said.
The county has 161,673 confirmed cases of COVID-19 and 4,154 deaths.
Statewide, California reported 400,769 total cases on Tuesday. That number will likely edge out New York's statewide total -- currently at 408,181 -- on Wednesday.
6:34 p.m.: Texas continues to see record hospitalizations
Texas reported a new record number of COVID-19 hospitalizations on Tuesday.
There are 10,848 patients currently hospitalized statewide, according to state data. Hospitalizations have remained above 10,000 since July 10.
The state saw 9,305 new cases on Monday, for a total of 341,739. There were 131 new fatalities, bringing the statewide total to 4,151.
The testing positivity rate was 15.05% as of Monday.
5:52 p.m.: Trump, at his 1st coronavirus briefing in 3 months, urges mask use
At President Donald Trump's first briefing focused on the coronavirus crisis in nearly three months, he encouraged people to wear masks and said that the pandemic will "get worse before it gets better."
The return of the briefings comes as cases of the coronavirus have surged in the country, particularly in the South.
"It will probably, unfortunately get worse before it gets better," Trump said. "That's the way it is."
The president said getting a vaccine "remains a top priority." Two vaccine candidates are entering clinical trials this month, and four others will in the coming weeks, Trump said. The military is ready to distribute them whenever they're ready, he added.
Dr. Anthony Fauci and Dr. Deborah Birx, fixtures at past briefings, were not in attendance Tuesday. Birx was "right outside," Trump said when a reporter asked where they were.
The briefing lasted about half an hour, in contrast to previous briefings, some of which came close to two hours long.
4:45 p.m.: Fauci says he was not invited to White House briefing
Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, told CNN Tuesday afternoon that he had not been invited to President Donald Trump's 5 p.m. White House briefing.
"I was not invited up to this point," Fauci said prior to the briefing. "I'm assuming that I'm not going to be there, because it's going to be in just a short while, and I'm still here at the NIH [National Institutes of Health]."
Asked when was the last time he spoke to the president, Fauci said he had a "good, long conversation with him towards the end of last week."
Fauci also responded to Trump's characterization on Fox News on Sunday that the nation's top expert on infectious diseases is an "alarmist."
"People have their opinion about my reaction to things," Fauci said. "I consider myself more of a realist than an alarmist."
Five months into the pandemic, Fauci said the U.S. testing system is "patchy."
"It isn't as uniform as we would like," he said. "We need to do better, particularly when you're dealing with the surges that we're seeing now in some of the southern states."
Asked what Americans need to do to slow the spread, Fauci said universal mask wearing, closing bars, physical distancing and good hand hygiene.
"It's not rocket science," he said.
4:20 p.m.: Louisiana extends Phase 2 restrictions for another 2 weeks
As hospitalizations rise, Louisiana is extending its Phase 2 restrictions until Aug. 7, Gov. John Bel Edwards announced Tuesday.
For the next two weeks, masks are mandatory across the state, crowds are limited to 50 people, and bars must be take-out only.
Louisiana is ranks second in the nation per capita in COVID-19 cases, the governor said.
3:50 p.m.: Nobel Prize banquet canceled for 1st time in over 60 years
The Nobel Prize banquet has been canceled for the first time in over 60 years due to the pandemic, the Nobel Foundation said Tuesday.
Usually all the Laureates and their families gather in Stockholm and Oslo in December and a traditional Nobel Banquet is held at the Stockholm City Hall.
This year, the award ceremony will still take place in Oslo and Stockholm on Dec. 10, but with "new formats that both comply with social distancing restrictions and take into account that only some or perhaps no Laureates will participate on site," the foundation said in a statement.
The banquet will be canceled because the event hosts over 1,000 people in an indoor space, the foundation said.
The Nobel Prizes will be announced in October as usual.
3:20 p.m.: California looking to continue to 'scale up' contact tracing
From the outset, officials in hard-hit California have envisioned reopening as a "dimmer switch," making modifications based on the ongoing data, California Health and Human Services Secretary Dr. Mark Ghaly said Tuesday.
"The overall health and well-being of Californians will always guide our decisions," he said, adding that state officials are open to adapting approaches.
"Our goal has always been to box the virus in with clear sector guidance ... as well as testing and contact tracing," Ghaly said.
Regarding contact tracing, Ghaly said, "we need to continue to scale it up ... even despite the fact that high levels of transmission have made traditional contact tracing impractical and difficult to do."
"Contact tracing is a tried-and-true method in public health," Ghaly said. "At the level of transmission that we're seeing across the state, even a very, very robust contact tracing program ... will have a hard time teaching out to every single case."
Thousands of state staff members have been trained and are ready to be deployed to counties, Ghaly said.
"As we build up the capacity county by county ... there are gonna be some novel and important approaches to reach out to contacts," he continued.
If COVID-19 positive people can make "that initial reach out ... that's another important way to reduce transmission," he said.
1:40 p.m.: Trump administration working with hospitals on religious accommodations
The Trump administration says it is working with hospitals on accommodations for religious leaders to visit patients and health care workers.
Roger Severino, director of the Office for Civil Rights at the Health and Human Services Department, told reporters Tuesday that the administration has helped to resolve several issues so far, including a medical student who didn't want to shave his beard but was told the N95 respirator wouldn't fit properly otherwise.
The student, who was on rotation at Staten Island University Hospital in New York City, was allowed to use a powered air purifying respirator instead, Severino said.
"This was a win-win situation," Severino said. "It avoided the difficult and painful situation of having to force someone to choose between their deeply held religious beliefs and pursuing the practice of medicine."
In another case, the Trump administration intervened when a Maryland woman was told in June that her husband couldn't receive visitors after being in a serious motorcycle accident. The hospital did not believe he was close to death and thought visitors presented safety concerns.
The Health and Human Services Department intervened and a priest was allowed to visit, Severino said.
"Spiritual needs don't exist only at the point of death" Severino said.
1:05 p.m.: South Carolina National Guard to help hospitals with surge
The South Carolina National Guard is sending about 40 medics to five hospitals to help respond to a COVID-19 surge, officials said Tuesday.
Georgetown County and Horry County have reported over 4,000 new coronavirus cases since July 1, hospital officials said.
All local hospitals are at or near capacity in their ICU, emergency and inpatient care departments, officials said.

11:40 a.m. Florida county asks parents to sign waiver for kids to take part in after-school activities
In Highlands County, Florida, parents must sign a COVID-19 waiver for students to take part in extracurricular activities this summer and during the upcoming school year, reported ABC affiliate WFTS.
The waiver asks that parents agree to check their children's temperature each day, visually inspect their children for signs of illness and confirm that the children have not been in contact with a coronavirus-positive person in the last two weeks. Parents also must agree to promptly pick up their children if they show signs of illness and to keep their children at home until they are illness-free for at least 72 hours without medicine.
The waiver is meant to remind parents that participating in any activity now carries a risk, Deputy Superintendent Andrew Lethbridge told WFTS.
11:05 a.m.: Florida has 5 counties with no available ICU beds

Of the adult ICU beds across the state, just 16.47% are available, the agency said.
Those numbers are expected to fluctuate throughout the day.
At least 21,780 coronavirus patients in Florida have been hospitalized since the pandemic began -- up 517 from Monday, according to the state's Department of Health.
Miami-Dade County, which includes Miami, and Bay County, which includes Panama City, are especially hard hit.
Miami-Dade County has a one-day positivity rate of 19.2% while Bay County's one-day positivity rate stands at 24.4%, according to the state's Department of Health.

9:25 a.m.: Cases in Alabama county double in 2 weeks
Officials in Calhoun County, Alabama, about 70 miles east of Birmingham, are pleading with residents to wear masks as COVID-19 cases surge in the area.
Of the county's 814 coronavirus cases, 430 of those were reported in just the last two weeks, Michael Barton, Director of Emergency Management for Calhoun County, said Monday.
"This is alarming," Barton said, adding that hospitals are at an "all-time high in reaching our capacity."
One local hospital had five COVID-19 patients two weeks ago. That hospital now has 44 patients.
Alabama Gov. Kay Ivey issued a mandatory statewide mask requirement last week.
"Make sure that you wear your mask and you adhere to all of the standards and guidelines that you possibly can," urged Joe Weaver, CEO at the local Stringfellow Memorial Hospital. "We know it's restrictive, but at the same time, there's no other thing. There's nothing else that we can do at this point in time."
4:43 a.m.: Russia's first COVID-19 vaccine ready, deputy defense minister says
Russia's first vaccine against the novel coronavirus is ready, First Deputy Defense Minister Ruslan Tsalikov told Argumenty i Fakty newspaper.
The vaccine was created by military specialists and scientists of the Gamaleya National Research Center for Epidemiology and Microbiology.
"Final assessments on the results of testing by our specialists and scientists of the National Research Center have been already made. At the moment of release all volunteers without exception developed immunity against the coronavirus and felt normal. So, the first domestic vaccine against the novel coronavirus infection is ready," Tsalikov told the newspaper.
2:43 a.m.: Fort Worth federal women's prison announces 3rd COVID-related death
The U.S. Bureau of Prisons announced late Monday a third COVID-related death at FMC Carswell, a specialized federal medical prison for women in Fort Worth, Texas.
Teresa Ely, 51, tested positive for COVID-19 on June 30 and was transported to a local hospital where she received treatment until she died Monday.
Ely had "long-term, pre-existing medical conditions, which the CDC lists as risk factors for developing more severe COVID-19 disease," the BOP said.
"Ms. Ely was a 51-year-old female who was sentenced in the Western District of Virginia to a 252-month sentence for Engaging in a Criminal Enterprise and Continuing a Criminal Enterprise," read a statement from the prison. "Ms. Ely had been in custody at FMC Carswell since September 19, 2007."
1:37 a.m.: NFL players will be tested daily for COVID-19 for at least the first two weeks of training camp
The NFL announced that players will be tested daily for the coronavirus for at least the first two weeks of training camp.
The league also made an offer to the NFL Players Association to play no preseason games this summer, a source told ESPN's Adam Schefter.
The players had been pushing to not play preseason games this year, and the league had been seeking to play two games instead of the usual four.
The league's proposal to the players includes an offer for a longer training camp acclimation period, a source told ESPN's Dan Graziano, and that is closer to what the union proposed.
The NFLPA has not yet informed the league whether it will accept the proposal.

12:45 a.m.: Church-related COVID-19 outbreaks continue to pop up in West Virginia
Several new COVID-19 outbreaks have been identified at churches in West Virginia's Grant, Logan, and Wood counties, West Virginia Gov. Jim Justice said Monday.
Last week, Justice said additional church-related outbreaks had already been identified in Boone, Kanawha, Raleigh, and Taylor counties.
Combined, the outbreaks in these seven counties account for about 75 total cases.
"We've absolutely got to stay on top of this," Justice said. "Please know that the church setting is the ideal setting to spread this virus."
The Governor urged all West Virginians attending church to follow the state's safety guidelines, including using every other pew, maintaining social distancing and wearing face coverings.
"I know these things are really difficult to do," Justice said. "But, for right now, they have to be done because, if we don't, all we're going to do is lose more people."
"We could very well lose a lot of our grandmothers and grandfathers – people who have so much wisdom to still continue to pass on – we absolutely don't need to be losing these great West Virginians," he said.
