"COVID-19 cumulative incidence in his county of residence and where the correctional facility is located was relatively low at the time of the investigation, suggesting that his most likely exposures occurred in the correctional facility through multiple brief encounters with IDPs who later received a positive SARS-CoV-2 test result", the CDC stated.
The 31 states are reporting at least 10% more new Covid-19 cases this week compared to last week: Alabama, Alaska, Arizona, Colorado, Connecticut, Florida, Idaho, Illinois, Indiana, Kansas, Kentucky, Louisiana, Massachusetts, Michigan, Minnesota, Mississippi, Nebraska, Nevada, New Jersey, New Mexico, North Dakota, Ohio, Pennsylvania, Rhode Island, South Dakota, Texas, Tennessee, Vermont, Wisconsin, West Virginia and Wyoming.

Redfield said the change in CDC guidance is an example of new data being incorporated into the agency's recommendations. "And clarifying that new science, that new data into our contact recommendations, is what you're alluding to".
Now, the definition from the CDC says that "total" contact of 15 minutes, over a 24-hour period constitutes "close contact".
"Although the correctional officer never spent 15 consecutive minutes within 6 feet of an [incarcerated person] with COVID-19, numerous brief (approximately one-minute) encounters that cumulatively exceeded 15 minutes did occur", the case study stated.
The United States has seen around 300,000 more deaths than usual since late January, with two-thirds attributable to COVID-19 and the rest due to other causes, a government study said Tuesday.
Dr. Butler said Covid-19 cases are now growing "really in all parts of the country", with particularly high transmission in the Midwest.
"The higher risk for certain complications among racial and ethnic minority patients provides further evidence that certain racial and ethnic minority groups are disproportionally affected by COVID-19 and that this disparity is not exclusively accounted for by age and underlying medical conditions", authors wrote.
During the briefing, Azar and Redfield discussed Operation Warp Speed, a partnership initiated by the Trump administration to accelerate the testing, supply, development and distribution COVID-19 vaccines, therapeutics and diagnostics. She says it does have "the potential to significantly increase the number of people who are asked to quarantine".
