Two members of Senator Kamala Harris' campaign staff have tested positive for COVID-19, forcing her to shut down travel for the foreseeable future as the presidential campaign enters the final few weeks, according to CNN. 

Democratic presidential nominee Joe Biden sent out a statement that said they put an end to any travel for Harris and her team after her communications director Liz Allen and a member of her flight crew caught the virus. 

In a statement on Twitter, Harris informed the public of the aides' diagnoses.

"Late last night, I learned a non-staff flight crew member & a member of my team tested positive for COVID," the vice presidential nominee wrote. "I wasn’t in close contact—as defined by the CDC—with either during the 2 days prior to their positive tests.I've had 2 negative tests this week & am not showing symptoms."

"Both the crew member and the staff member were wearing N95 masks at all points they were near me, and our doctors believe that we were not exposed under CDC guidelines. Out of an abundance of caution, I will cancel travel through Sunday and continue to campaign virtually," she wrote.

"I will be transparent with you about any test results that I do receive. In the meantime, remember: wear a mask, practice social distancing, and wash your hands regularly. It is possible to stop the spread," she added.

Biden campaign manager Jen O'Malley Dillon told CNN in a statement that neither person has had any contact with Harris or Biden for at least two days. 

"After being with Senator Harris, both individuals attended personal, non-campaign events in the past week. Under our campaign's strict health protocols, both individuals had to be tested before returning to their work with the campaign from these personal events," Dillon said.

"These protocols help protect the campaign, the staff, and anyone who they may have contact with; the importance of having such protocols — which include testing before resuming duties, regular testing while working in-person, isolation after time off, and masking and distancing while on campaign duties — have been illustrated once again," she said. 

Dillon added that Harris was last tested for coronavirus on Wednesday and tested negative. She went on to describe Harris' travel since debating Vice President Mike Pence on October 8 and offer more details about the contact other members of the campaign have had with the two people who tested positive. 

CNN noted the stark difference in how the Biden campaign and campaign of President Donald Trump have handled positive coronavirus tests. Dillon said the Biden campaign has already started a contact tracing effort to help figure out how the two campaign members tested positive and when. The campaign has very strict testing protocols and forces anyone who attends private events outside of the campaign to be tested before returning to their jobs, according to Politico.

Trump has refused offers from the CDC to conduct any contact tracing efforts after he and dozens of people on his campaign team and in the White House tested positive for the virus. He has even returned to campaigning ahead of doctor's orders, angering health officials who say he may still be contagious and is setting a bad example for the rest of the country. 

Harris spoke about how difficult it was to campaign during the coronavirus pandemic during an interview on MSNBC on Wednesday.

"I'd like to hug people. You don't hug people these days. That's not an option. You can't shake hands. But you can look people in the eye, and you can listen, and you can be there," Harris said.

"I think it's important to be where the people are but to do it in a way that does not cause them to be at any risk in terms of their safety. And so we're working it out. It's definitely a different kind of campaign than anything that we've done before, but we're making the best of it," she added.

According to Politico, before her travel was cancelled Harris was slated to go to North Carolina and campaign in Charlotte as well as Asheville. She was also set to head to Cleveland on Friday, Pennsylvania this weekend and Texas next week. 

Harris has been off the campaign trail in recent days as she grills Supreme Court nominee Amy Coney Barrett during confirmation hearings this week, according to the Associated Press. She has been attending the sessions virtually due to the infections of multiple Republican colleagues on the Senate Judiciary Committee.
