Beijing, China (AP) — As countries consider how to restart their virus-halted economies, the early experiences in China and parts of Europe show it will be no easy task. Workers back on the job are wary of spending much. Shoppers are staying away. Masks and social distancing measures are not fading. And pervasive is the fear the coronavirus could return if lockdowns meant to stop its spread are eased too much, too quickly. Still, leaders are anxious to reopen factories, schools and shops and to repair the economic damage from the pandemic that has claimed more than 137,000 lives.
