The number of confirmed cases of COVID-19 soared 30% over the weekend as testing capacity has been expanded and outbreaks have worsened in Germany, Italy, Spain and the U.S.

In the U.S., there are 41,511 cases and 499 deaths, as of Monday morning, according to the latest aggregated data from the Johns Hopkins Whiting School of Engineering’s Centers for Systems Science and Engineering. On Friday afternoon, there were 16,018 cases and 210 deaths.

New York City is now largely considered the epicenter of the outbreak in the U.S., with 12,339 cases and at least 99 deaths. The city conducted 13,000 inspections of nonessential businesses including bars, restaurants and gyms in New York City over the weekend. Eleven violations were issued. “That’s how seriously New Yorkers are taking this,” New York City Mayor Bill de Blasio tweeted on Sunday.

In various parts of the city, stores that have remained open including some C-Town Supermarkets, Rite Aid Corp. RAD, +1.71% pharmacies, and Micro Center electronics retailers have limited the number of people who can enter the store. At a farmers market in New York City’s Inwood neighborhood, shoppers weren’t allowed to handpick produce and waited in spaced-out lines that stretched down the block. At the New York-Presbyterian academic medical center, a new policy isn’t allowing birthing partners and support individuals to enter the hospital for obstetric patients.

There are a total of 20,875 cases and 157 deaths in New York state. Gov. Andrew Cuomo tweeted this weekend that the state is considering turning the Javits Center, one of Manhattan’s largest conference centers, as well as Stony Brook University, SUNY Old Westbury, and the Westchester County Center into hospital sites. Cuomo said Monday that the state is now testing 16,000 people a day for the novel coronavirus.

Worldwide, there are now 367,457 cases of COVID-19 and at least 16,113 people have died. About 100,000 people have recovered.

In Italy, which has become the epicenter of the pandemic in recent weeks, there are now 63,927 cases and 6,077 deaths. Other outbreaks of concern include France, with 16,937 cases and 676 deaths; Germany, with 28,865 cases and 118 deaths; Iran, with 23,049 cases and 1,812 deaths; and Spain, with 33,089 cases and 2,206 deaths. In South Korea, which has been cited as a model for containment, there are 8,961 cases and 111 deaths.
