In the U.S., the White House released guidelines to re-open the country in three phases. It proposes that schools may reopen in “phase two,” along with theaters, religious centers, sporting events and restaurants. The guidelines suggest that states could make the decision after documenting a 28-day decrease of COVID-19 cases and putting in place a strong testing program. The Johns Hopkins Center for Health Security supports plans to re-open the U.S. in phases. The center, however, notes that there are still unanswered medical questions. One is about the rate at which children can spread the virus to others. That unknown makes it more difficult to know when schools should reopen. The center suggests, “If schools are reopened, decisions will need to be made regarding whether tele-education will need to be provided to those students who do not come back to school, alongside in-person education being provided in school.”
