Time to start paying attention to effect of the protests as it’s been at least two weeks since they started.
“One month later, thousands of people came together for large demonstrations following the death of George Floyd— and images from protests across the country have not shown much physical distancing. Some, such as Dr. Anthony Fauci, have speculated that the protests could lead to a surge in virus infections, confirmed cases and hospitalizations, and UCSF epidemiologist Dr. George Rutherford believes we’ll be able to gauge the impact of the protests on transmission very soon.“
“Pick any day of protest, and then look seven, eight, nine or 10 days after the protest,” he said. “I think the easiest thing to look at is case counts, which is not a perfect metric since you have to factor in increased testing. We’re finding more asymptomatic cases now, so it’s not exactly comparable to March and April, when most detected cases were symptomatic. Now in May and June, we’re catching more asymptomatic cases so it can be hard to interpret since we’re finding more infections.”
“Rutherford believes that up to 60% of infections are either asymptomatic or so mild an individual does not think to get tested — which means that increased testing will yield more confirmed cases if you expand testing to be available to anyone regardless of symptoms. Because of enhanced testing capabilities, Rutherford believes hospitalizations and percent positivity of tests are the best metrics to use when measuring spread.”
“However, even when looking at confirmed case counts, Rutherford is encouraged by what he sees in Minnesota, which is where the protests started on the week of May 25. It has been almost a full two weeks since the protests began, and the number of new confirmed cases statewide is actually trending downwards.”
“If the protests don’t cause a jump in confirmed cases, there are two reasons for it. One: transmission didn’t occur at a great extent thanks to masks, social distancing, and people being outside,” he said. “Or Two: there was an increase in transmission but we’re not seeing it because asymptomatic and presymptomatic people aren’t being tested.”
“The vast majority of protesters did not maintain six feet of physical distancing at all times, which means masks and and the open-air environment may have helped keep transmission low.”
