Health experts say the federal government is still not adequately responding to the coronavirus threat and is failing to inform the public, medical community, and local governments fully about the massive scale of domestic preparations necessary.

President Trump attempted to reassure the public Wednesday evening that the 15 cases found in the United States, as opposed to cases involving those who were repatriated to the U.S. after getting sick abroad, will drop to zero in a “few days.” And he said his administration was taking an aggressive approach to kill the threat before it wreaks havoc, as health experts predicted it would earlier this month.
