Higher trust in public health agencies during COVID-19 driven more by beliefs that agencies led with clear, science-based recommendations and provided protective resources, than by beliefs that agencies controlled outbreak

Researchers found that trust in federal, state, and local public health agencies was driven by beliefs in scientific expertise and provision of direct care, not control of outbreaks. Lower trust was related to concerns about conflicting recommendations and perceived political influence.
