Child abuse reports have plunged during the coronavirus pandemic, a troubling sign that the constraints of social distancing may mean thousands of cases are being missed, a new survey suggests. The survey, conducted by the Children's National Alliance, found that children's advocacy centers across the country reported serving 40,000 fewer children nationwide during the first six months of this year than the same period last year, the Washington Post reported. In 2019, more than 192,000 children were served by the centers while just over 152,000 were helped in 2020, a 21 percent drop, the survey showed.
