Transcript for Sturgis rally draws massive crowd as COVID-19 cases increase in US
We're going to start with the latest on the pandemic. As the world nears 20 million coronavirus cases, deaths here in the U.S. Are increasing in 28 states and the Puerto Rico. Hospitalizations are up in 27 states, D.C. And Puerto Rico. With the race on to develop a vaccine, a gallop poll finds 65% of Americans would get the vaccine if it were fda approved and free. But more than a third of those polls said they would not. Expert and advisory member board Dr. Paul offit joins us to discuss the importance of an effective vaccine. In South Dakota thousands of people are gathering in what could be the largest event in America since the pandemic began. ABC's Trevor Ault is there in Sturgis with the very latest. Trevor, good morning to you. Reporter: Good morning, whit. Here at the Sturgis motorcycle rally the bikers are not oblivious to the pandemic. There are venders selling t-shirts taunting the virus and these streets have been packed with people who either think the threat is overblown or they simply don't care. Health officials worry that this could be a super spreader event as hospitalizations and deaths are on the rise in. With the U.S. Fast approaching 5 million confirmed cases, and recording 2,000 more deaths in a 24-hour span for the first time since may, hundreds of thousands of bikers are converging on South Dakota's Sturgis motorcycle rally, many aware but unafraid of the pandemic. The state is seeing a daily increase in both positive cases and deaths. It kept a lot of people away. I can understand their feelings. For me, it's a release. Reporter: 250,000 people are expected to attend, the largest gathering the country's had since covid-19 took hold. Nationwide the horrors of the virus continue to add up. California now passing 10,000 deaths and in Georgia a pheartbreaking loss, a 7-year-ol African-American boy with no underlying conditions dying from the virus. While in Texas Vanessa Martinez is warning of the dangers for young children after her 2-year-old and 8-month-old tested positive. A lot of people here only thought it would affect adults and not children. Reporter: On the heels of a CDC report that found staggering racial disparities among children, the data showing black children with covid-19 were hospitalized five times as often as white children and hispanic children eight times as often as whites. This morning more states heading backwards. Hawaii closing oahu beaches. Oregon considering limiting interstate travel and Massachusetts cutting gathering sizes in half. People are simply not being responsible about face coverings, social distancing or any of the major metrics. Reporter: With no concrete end in sight, Dr. Anthony Fauci continues to say he's cautiously optimistic about a a vaccine and he had a similar feeling about the country if Americans can unify behind basic health practices. I don't think we need to go into the fall and the winter thinking we could have a catastrophe. We could go into the fall and the winter coming out of it looking good. Reporter: Some areas are taking more aggressive steps toward returning to normal life. Baltimore has re-opened indoor dining and governor Cuomo says schools in every region can return to in-person lining. I just want to push it to as last minute as I could because really, as you see, there really is not a lot of specific information. Reporter: Some districts are already dealing with the impact of covid outbreaks. In Alabama a slew of positive tests has forced the entire football team and band to quarantine. Here in Sturgis the majority of residents said they wanted this rally to be canceled this year. Good luck telling hundreds of thousands of bikers what to do. The city figured they would come anyway so they decided to continue hosting the event, provided sanitation and hand sanitizer. When the rally ends next weekend, there will be mass testing for the population of Sturgis. Eva? Trevor, thank you.
