Young people are infecting older family members in shared homes

Washington Post: As the death toll escalates in coronavirus hot spots, evidence is growing that young people who work outside the home, or who surged into bars and restaurants when states relaxed shutdowns, are infecting their more vulnerable elders, especially family members. Front-line caregivers, elected officials and experts in Houston, South Florida and elsewhere say they are seeing patterns of hospitalization and death that confirm fears this would happen, which were first raised in May and June. That was when Florida, Texas, Arizona, California and other states reopened in efforts to revive their flagging economies.

How much coronavirus risk is there in common travel activities? We asked an expert

USA Today: Travel in the middle of a global pandemic presents challenges, with each activity carrying its own level of risk for coronavirus. Joseph Khabbaza, a pulmonary and critical care physician at the Cleveland Clinic, said some of the biggest questions he’s getting relate to travel activities. Khabbaza, who treats coronavirus patients, said the primary path of transmission is contacts with respiratory droplets produced by infected people. Face masks, physical distancing, frequent hand-washing and cleaning and disinfecting of surfaces have become standard across the travel sector.

Quotable: Behavioral science can help curb coronavirus spread

“Despite surging Covid-19 cases around the country, groups continue to flout public health guidance about safe practices. Some instances are particularly flagrant, such as Alabama college students reportedly organizing “Covid parties” to intentionally infect attendees. But individual examples reflect a broader trend: since late May, a growing proportion of Americans have socialized with people outside of their own households, with up to a third doing so without maintaining social distancing. It is easy to write off this behavior as a result of poor awareness and the spread of misinformation. But decision science suggests that it may be dictated by group behavior as much as faulty information. Humans are social beings that seek out surrounding norms to inform what is deemed to be appropriate choices. The tendency to follow the “wisdom of the crowd” or make choices based on what others do (e.g., friends, public figures) is known as social proof. To change Covid-related behaviors, we must implement policies and programs that also harness the power of social influence to fundamentally change social norms.”

US health officials estimate 20M Americans have had virus

Associated Press: U.S. officials estimate that 20 million Americans have been infected with the coronavirus since it first arrived in the United States, meaning that the vast majority of the population remains susceptible. Thursday’s estimate is roughly 10 times as many infections as the 2.3 million cases that have been confirmed. Officials have long known that millions of people were infected without knowing it and that many cases are being missed because of gaps in testing.
