Celebs participating in the #PassTheMic campaign will hand their social media accounts over to a COVID-19 expert for the day to spread awareness about how people can help end the pandemic and to hear from those who, according to the promotional video, "actually know what they're talking about". Julia has 8.7 million followers on Instagram.
Roberts will be the first to surrender her accounts - to Fauci - for the campaign.
Experts including Dr. Anthony Fauci will use the stars' platforms to share facts and science-driven perspectives on the pandemic. It's run by ONE, a worldwide marketing campaign to finish excessive poverty and preventable illness by 2030.
The Pretty Woman star spoke with Fauci, a prominent member of the White House's coronavirus task force, as she hosted a virtual chat with the director of the National Institute of Allergy and Infectious Diseases on her Instagram page.
In the interview with Roberts on his personal account on the social networks, Fauci said that the main problem to solve is "health disparities extraordinary" between the countries.
"Right now, if you take southern Africa, sub-Saharan Africa, parts of Asia, South America and even parts of the Caribbean as areas that don't have the healthcare system to be able to respond the way one can respond in NY or L.A. or New Orleans or Chicago, we have really a moral responsibility for people throughout the world", Fauci said.
