Israel closed schools again in early June after 244 infections were identified among children and staff across multiple schools, including 130 at one alone, the report said. "We need to avoid broad, sweeping mandates requiring schools to open and children to attend in person," Dr. Charlene Wong, an assistant professor of pediatrics at the Duke School of Medicine, said Tuesday on the call. "The only way to open schools safely is to have a comprehensive approach to reduce transmission within the community, and the United States is quite unique in that it could be the first country to reopen schools with rising infection rates in some places," Dr. Ibukun Christine Akinboyo, medical director of pediatric infection prevention at Duke University Medical Center, said Tuesday.
