Recital 21

(21)The Member States have a responsibility to manage public health crises at national level. However, measures taken by individual Member States could damage the interests of other Member States if they are inconsistent with one another or based on diverging risk assessments. The aim to coordinate the response at Union level should, therefore, seek to ensure, inter alia, that measures taken at national level are proportionate and limited to public health risks related to serious cross-border threats to health, and do not conflict with obligations and rights laid down in the TFEU such as those related to the restriction on travel and trade.
