Since the start of June, 14 states and Puerto Rico have recorded their highest-ever seven-day average of new coronavirus cases since the pandemic began, according to data tracked by The Washington Post: Alaska, Arizona, Arkansas, California, Florida, Kentucky, New Mexico, North Carolina, Mississippi, Oregon, South Carolina, Tennessee, TEXAS, and Utah.
SUMMARY: Findings This case series included 58 hospitalized children, a subset of whom required intensive care, and met definitional criteria for pediatric inflammatory multisystem syndrome temporally associated with severe acute respiratory syndrome coronavirus 2 (PIMS-TS), including fever, inflammation, and organ dysfunction. Of these children, all had fever and nonspecific symptoms, such as abdominal pain (31 [53%]), rash (30 [52%]), and conjunctival injection (26 [45%]); 29 (50%) developed shock and required inotropic support or fluid resuscitation; 13 (22%) met diagnostic criteria for Kawasaki disease, and 8 (14%) had coronary artery dilatation or aneurysms. Some clinical and laboratory characteristics had important differences compared with Kawasaki disease, Kawasaki disease shock syndrome, and toxic shock syndrome.
J. Harris: I believe that all of these children survived, although several have coronary artery aneurysms at this time. This is a bad virus; it can be devastating for children as well as adults.
A widely cited paper published in April suggested that people are most infectious about two days before the onset of symptoms, and estimated that 44 percent of new infections are a result of transmission from people who were not yet showing symptoms.
All of the best evidence suggests that people without symptoms can and do readily spread SARS-CoV-2, the virus that causes Covid-19,” scientists at the Harvard Global Health Institute said in a statement on Tuesday.
The Bucks County Health Department in Pennsylvania reported 33 new coronavirus cases Saturday, including 11 that can be traced back to a New Jersey resident “who attended multiple house gatherings at the Shore during the past two weeks.”
The study evaluated 1,717 policies implemented in China, South Korea, Italy, Iran, France and the United States in the period extending from the emergence of the virus in January to April 6, 2020.
Emergency COVID-19 measures prevented more than 500 million infections, study finds
An objective of the study was to understand which policies have played the greatest role in slowing the pandemic.
The team found that home isolation, business closures and lockdowns (a component of emergency declarations in some countries) often produced the clearest benefits. Travel restrictions and bans on gathering had mixed results, with large effects in some countries — Iran and France, respectively, for example — and less clear benefits in countries such as the United States.
The researchers did not find strong evidence that school closures had an impact in any country, but they cautioned that their finding is not conclusive and that more research should be used to inform school policies.
The team found that while some policies change behavior immediately and may have quickly led to small benefits, it took three weeks, in general, for policies to achieve their full impact on the spread of COVID-19. Now that some countries are relaxing policies, Hsiang said, “we might reasonably expect signals of any renewed spread to emerge on a similar two- to-three-week time frame.”
