WASHINGTON – A sharp decline in routine medical care for low-income children during the coronavirus shutdown could cause long-term harm if not reversed, federal officials warned Wednesday.A data snapshot from the Centers for Medicare and Medicaid Services, or CMS, found that vaccinations, screening for childhood diseases, visits to the dentist and even mental health care dropped precipitously from March through May of this year, when doctors' offices and hospitals put elective services on hold to confront the coronavirus.“The absence of these vital health care services may have lifelong consequences for these vulnerable children, and I call on states, pediatric providers, families, and schools to ensure children catch up," CMS administrator.
