A Southern California-area hospital system, immigrant advocacy groups and Americans living in Mexico criticized on Tuesday a draft proposal by the U.S. government that could block U.S. citizens and permanent residents from entering the country if they are suspected of being infected with the novel coronavirus.

The pushback comes a day after news outlets reported the administration of U.S. President Donald Trump was considering a regulation that would give the government authorization to keep out Americans believed to have contracted COVID-19 or other diseases.

Chris Van Gorder, CEO of Scripps Health, which operates five hospitals in San Diego County, said the hospital system "would never endorse American citizens not being able to get the care they need."
