I think mask wearing and social distancing is slowing the spread in some places. CA and OH for example have seen a slow when more stringent policies were put into place. But I don't think Louisiana and Florida are being more careful and they are seeing a drop in cases. |

> What do scientists do in the face of uncertainty on the value of global interventions? Usually, they seek an answer with adequately designed and swiftly implemented clinical studies as has been partly achieved with pharmaceuticals. We consider it is unwise to infer causation based on regional geographical observations as several proponents of masks have done. Spikes in cases can easily refute correlations, compliance with masks and other measures is often variable, and confounders cannot be accounted for in such observational research.
