The coronavirus continues to spread worldwide, sparking alarm and drastic emergency measures, even as the situation stabilizes in China.

Here are the latest developments:

China is stabilizing: The country only reported 19 new cases today, a drastic drop from the peak just a month or two ago, when it was still reporting thousands of new cases per day. Yesterday was also the third straight day in which there were zero locally transmitted cases outside of Hubei.

Xi is in Wuhan: Perhaps the strongest indicator that things are calming in China is Chinese President Xi Jinping's visit to Wuhan, the epicenter of the outbreak, today. Xi will visit medical workers, army troops and police officers, volunteers and patients, and more, state media reported -- a symbolic show of confidence in China's containment of the virus.

South Korea slowdown: The number of new cases per day is also dropping in South Korea. It's only been a few days of improvement so it may be too early for celebration -- but the country's health minister told CNN he was "cautiously expecting we have passed the peak" of the outbreak.

Italy is locked down: In a complete contrast, Europe is now facing a worsening outbreak. All of Italy and its 60 million residents are under total lockdown -- this means restricted movement, school closures, a ban on all public events, and suspended religious services including weddings and funerals.

The drastic measures were taken in response to a healthcare system overwhelmed by the flood of patients -- but some Italian officials worry it still isn't enough.

US cases are rising: The US now has at least 728 cases and 26 deaths, sparking alarm from local and health officials. Many states are declaring states of emergency, and even congressmen are self-quarantining after coming in contact with an infected patient.

Schools nationwide are beginning to close and conduct online classes instead, and large employers like Amazon are asking workers in virus-hit areas to work from home.

All this comes as friction grows between local authorities and the Trump administration, with increasing dissonance between states' calls for action and federal reassurances.
