Weeks after China announced the outbreak of the coronavirus, the international community has taken measures to prevent a widespread epidemic.

Countries have begun to limit travel to the infected mainland China and Hubei province – the epicenter of the virus – with the U.S. Centers for Disease Control and Prevention (CDC) advising travelers to avoid all nonessential travel to the country.

The first person-to-person spread of the disease occurred in mid-December, according to Chinese researchers.

Evacuations have been issued, with world health officials expressing "great concern" the disease is starting to spread among people outside of China.

Coronavirus now infected more people in China than were sickened during the SARS outbreak in the early 2000s.

Here are the latest figures.

How many have been infected or have died?

The death toll from the virus rose to 170 on Thursday, with a total of 7,711 infected. Over the past 24 hours, 38 new deaths and 1,737 new infected cases have been reported.

Roughly 99 percent of new cases have appeared in China. Of the new deaths, 37 occurred in Hubei province, with one in the southwestern province of Sichuan. The virus has been reported in at least 16 countries globally.

The United States currently has six cases of the virus: two in California, one in Arizona, one in Washington and two in Illinois, health officials say. The sixth case was confirmed Thursday in a Chicago resident, who is the spouse of the first confirmed travel-related case in Illinois. The new case marks the first in the U.S. that occurred via person-to-person transmission, CDC officials said.
