In a statement Saturday, the president of the Miami-Dade teacher's union, Karla Hernandez-Mats, said the rise in cases at MAST and other schools sites was "detrimental and a sign of community negligence." "This virus is not being propagated within our schools, but rather being brought in from the outside and putting everyone at risk," the statement said. "Our teachers and students are exhausted and until the community behaves responsibly and rigorously follows the CDC guidelines, these interruptions will continue to be our norm. Schools with such high numbers of detected cases should go into full quarantine to ensure safety." Miami-Dade County Public Schools officials responded that they continue to follow public health guidelines.
