What’s more, some children with COVID-19 only have GI symptoms, adds José Mayorga, M.D., Executive Director of UCI Health Family Health Centers. He has seen this among his patients and his own children. “It actually happened in my own family,” he shares. “One of my daughter’s had the classic upper respiratory infection, the other one had stomach issues. They both tested positive for COVID.” … Dr. Mayorga adds that, because COVID-19 in children can sometimes present with GI symptoms alone, it’s usually best to get tested if you’re unsure. This is especially true during COVID-19 surges.
