What you need to know today about the virus outbreak

President Donald Trump is raising the idea of what he's calling a quarantine involving New York and parts of New Jersey and Connecticut, states hard-hit by the coronavirus pandemic. But there are questions as to whether the federal government has the power to do so. Trump says he was thinking it would just be “for a short period of time if we do it at all.”

The United States has more confirmed coronavirus infections than any other country. Cities including Detroit, Chicago and New Orleans are growing as hotspots of infection, while New York City continues to be pummeled. Nurses there are calling for more masks and other gear to safeguard themselves against the virus that has so far sickened more than 52,000 people and killed over 700 in New York state, mostly in the city.

New York's governor has delayed the state's presidential primary from April to June to keep people from gathering during the coronavirus pandemic. More than a dozen states have delayed some elections, in some cases including their presidential primaries.
