WASHINGTON - For the millions of Americans living under some form of lockdown to curb the spread of the coronavirus, not knowing when the restrictions will end is a major source of anxiety.
Will important life events be delayed for a few weeks, a few months or much longer? Scientists are reluctant to predict exactly when restrictions could be safely loosened.
Based on China's experience, that could come approximately six to eight weeks after lockdowns are implemented.
But scientists say the choice is not simply between completely shutting down the country or throwing all rules out the window. Instead, imagine that a lockdown has a volume dial that can be twisted up or down.
