Back now with the latest on the pandemic. There are growing concerns that the coronavirus could spread at these large gatherings and Steve osunsami joins us from Atlanta with the latest on that good morning, Steve. Reporter: Good morning to you, George. Health authorities are telling protesters that they should probably be self-quarantining when they get back home and at a minimum should be wearing face coverings in large crowds. A new study shows how well that masks and social distancing measures work. A study in the journal lancet found standing three feet away lowered the risk but more distance was better and found a distance of ten feet can cut the risk in half. The study also found that wearing face coverings is helpful. The risk of transmission while wearing one was 3% versus 17% when you're not wearing one. Health authorities are warning protesters who are filling the streets across the country saying that the coronavirus is probably marching with them. Atlanta's mayor is encouraging testing. If you were out protesting last night, you probably need to go get a covid test this week. Reporter: Doctors are likely saying we'll see more cases in a week. We might have more hot spots because, again, large crowds, closed setting and some people that are out might be actually carrying the disease, right, the asymptomatic population. Reporter: In these 15 states and Puerto Rico the number of newly reported cases is increasing, places like Tennessee, South Carolina and California where protests are quite large. But the people marching for justice say it's a risk they'll take. There's a problem in this end emkick bigger than covid-19. Covid will come and go but our lives, once it's gone, it'll never come back so it's important that we must stand up now and demand change. Reporter: Health officials say there are things people marching can do to fry to protect themself. Take your mask and wear it at all times. I know it'll be difficult. But the farther away you can stay from people the better.
