The novel coronavirus pandemic has now killed more than 664,000 people worldwide.
Over 16.9 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 4.4 million diagnosed cases. On Wednesday, the U.S. death toll climbed over 150,000 and now stands at 150,649.
Texas reports day of record fatalities Cases cross 100 in a day in Hawaii for 1st time NJ counties reemerging as 'hot spots' Alabama, Maryland enforce new mask mandates
Here is how the news developed on Wednesday. All times Eastern.
9:35 p.m.: Hawaii crosses 100 daily cases for 1st time
Hawaii reported a record number of new COVID-19 cases on Wednesday, with gatherings contributing to the rise, officials said Wednesday.
There were 109 daily new cases -- marking the first time that number has crossed 100 in the state, Gov. David Ige said at a press briefing.
There have been 958 cases so far in July -- more than any other month so far, officials said.
Ige said he's now considering imposing restrictions, including closing bars, limiting gatherings to 10 people and limiting social gatherings on beaches.
"We are seeing infections occurring at personal gatherings of family and friends," Ige said.
Funerals have also contributed to "a lot of the cases," Bruce Anderson, director of the state health department, said.
9:15 p.m.: LA County reports record number of COVID-19 deaths
Los Angeles County reported its highest number of deaths from COVID-19 on Wednesday.
There were 91 new deaths, though officials said that there was a backlog in reporting and some of the deaths occurred earlier. There have been 4,516 total COVID-19 deaths in the county.
Outside of institutions, two-thirds of those deaths were men, Mayor Eric Garcetti said at a press briefing Wednesday.
"So men, mask up," Garcetti said. "Men, take responsibility and social distance."
Other COVID-19 numbers in the county are marginally better than in previous weeks. One in 450 people in the county are thought to be currently infectious -- versus 1 in 320 last week, Garcetti said.
7:15 p.m.: US reports most deaths since mid-May
The U.S. has recorded its highest number of deaths from COVID-19 since mid-May, according to The COVID Tracking Project.
There were 1,418 deaths reported on Wednesday, the most since May 15, the project found.
OK, our daily update is published. States reported 840k tests completed, nearly 66k new cases, and hospitalizations ticked up. The major observation, however, is that states reported more than 1400 deaths today, the most since May 15. pic.twitter.com/PGCu7Z4pXC

That number was largely driven by southern states, which reported 962 deaths on Wednesday, the project said. Nearly a third of those were in Texas, which reported a record 313.
The project noted that the state has changed its method of counting deaths, and Hurricane Hanna may have caused some backlog, possibly impacting the number reported.
6:40 p.m.: Maryland expands mask order, discourages travel to hotspots
Maryland is expanding its mask mandate and has implemented an out-of-state travel advisory amid rising COVID-19 hospitalizations, Gov. Larry Hogan said Wednesday.
Marylanders ages 5 and up will now be required to wear face coverings in public spaces of all businesses and outdoors in public when physical distancing is not possible. The new order goes into effect Friday at 5 p.m. It expands upon the existing order, in effect since April 18, which required face coverings in stores and on public transit.
The state is also immediately advising against travel to states with positivity rates of 10% or higher. As of Wednesday, the state said its advisory applies to nine states: Alabama, Arizona, Florida, Georgia, Idaho, Louisiana, Nebraska, South Carolina and Texas.
Maryland is also pausing its reopening, Hogan said; statewide it is in stage 2 of a three-stage plan.
"We are doing much better on our health metrics than most of the rest of the country, and we are doing much better on our economic recovery than most of the rest of the country, and we want to do what it takes to keep it that way," Hogan said.
Maryland has 86,285 confirmed cases of COVID-19, according to state data. Its testing positivity rate is nearly 5%. Hospitalizations and new cases have increased steadily in July.

This includes extending the statewide mask ordinance through Aug. 31, Ivey said at a news conference.
At school, second-graders through college students are required to wear masks, she said.
Ivey said she encourages schools to phase-in classroom learning when and where possible.
"I respect those districts that have elected to go to virtual classrooms," Ivey said, adding that she believes "a slide will come by keeping our kids at home."
"And that slide is likely to have a dramatic, negative impact on Alabama's future -- our young people," the governor said.
Alabama has over 81,000 confirmed cases and more than 1,400 confirmed fatalities, according to state data.
In the last few days, some hospitals have set all-time high patient numbers, state health officer Dr. Scott Harris said Wednesday.

His staff has not responded to requests for comment.
Gohmert was in the House Judiciary Committee hearing on Tuesday for Attorney General William Barr's hearing.
Barr will be tested for COVID-19 on Wednesday, Department of Justice spokesperson Kerri Kupec said. Video from Tuesday showed Gohmert walking into the hearing room in close proximity to Barr; neither wore a mask.

4:25 a.m.: McAllen, Texas Convention Center will be used to treat coronavirus patients
Texas Gov. Greg Abbott announced Tuesday that the McAllen Convention Center would be transformed into a temporary medical facility to treat coronavirus patients.
Abbott visited the Rio Grande Valley on Tuesday to survey damage caused by Hurricane Hanna and meet with local leaders -- who are contending with both hurricane damage and the coronavirus pandemic.
"And if there's one thing that I want to emphasize to everyone in the Rio Grande Valley it is this: This hurricane has not eliminated COVID-19," Abbott said.
Abbott announced several major steps designed to assist the Valley, including:
-The McAllen Convention Center will be transformed into a temporary medical facility to treat coronavirus patients. The convention center's maximum capacity will be 250 patients, Abbott said.
-The U.S. Department of Defense will deploy additional medical teams to the Valley. A U.S. Army Reserve unit arrived in Cameron County on Tuesday to assist local hospitals.
Another U.S. Army Reserve unit will arrive in Hidalgo County on Wednesday to assist DHR Health.
"This is on top of the more than 2,000 medical personnel that we have already allocated to this region," Abbott said.
Starr County Judge Eloy Vera said hospital capacity remains a major problem.
Adding capacity in Hidalgo County and Cameron County will help Starr County, Vera said.
3:07 a.m.: 73 COVID cases in Illinois traced to July 4 parties
Seventy-three people are now part of a COVID-19 outbreak in Lake Zurich which has been traced back to several Fourth of July gatherings, health officials said.
The outbreak was first detected in a group of Lake Zurich High School students earlier in July. Lake County, Illinois, health officials said contact tracing has now led them to believe the infections stem from multiple July 4 parties, and was not the result of a super spreader event.
"We have identified multiple smaller gatherings where COVID-19 infections occurred," said Hannah Goering, Lake County Health Department.
The outbreak was detected on the first day of an athletic camp scheduled to take place to Lake Zurich High School, when several students tested positive during an initial health screening. The camp was cancelled, and a mobile testing unit was sent to the high school for several days. Free testing was offered to those in the area.
"At least half of the cases are Lake Zurich High School students, but there are also parents and family members and people from other community members tied to this outbreak," Goering said.
County officials said during this process they've had some trouble with contact tracing, as many people have either ignored messages, delayed responding, or simply didn't pick up the phone. They said they really need anyone who is contacted by a tracer because of possible exposure to COVID-19 to take the call seriously and get themselves tested as soon as possible.
