CLEVELAND, Ohio — No new novel coronavirus cases were reported Tuesday in Ohio, but the number of people being tested in the state has tripled.

The Ohio Department of Health’s website listed 15 Ohioans currently being tested for COVID-19. This is the highest number of people in the state being tested for the respiratory illness since its outbreak nearly a month ago.

The Ohio Department of Health began testing for COVID-19 on Saturday and has the capacity to test about 300-400 people. Other private companies, including LabCorp and Quest also will be offering tests. Before that, only a handful of people had been tested.

Of Monday’s confirmed cases, all three are in Cuyahoga County but none are in the city of Cleveland, health officials said. Two people were on a cruise in Egypt, and the other was at an American Israel Public Affairs Committee conference in Washington, D.C. All are aged 54-56. Two cases involve men, and the other case involves a woman.

All three people with COVID-19 are in isolation at their homes and under remote supervision by their health care providers, Cuyahoga County Health Commissioner Terry Allan said.

One of the three people who tested positive for the novel coronavirus in Ohio is a male employee of the Jewish Education Center of Cleveland, located in Cleveland Heights. Four Hawken School students who traveled last week to a conference in Washington, D.C., with a man who has tested positive for coronavirus are self-quarantined, according to the school.

The students, who attend Hawken’s Upper School campus in Gates Mills, traveled to the American Israel Public Affairs Committee (AIPAC) conference on the same bus with an employee of the Jewish Education Center of Cleveland.

The number of Ohioans under public health supervision remains at 255. This number is updated only on Wednesdays. This figure reflects travelers referred to ODH for monitoring; the number includes travelers who have finished their self-monitoring home quarantine, health officials said.

The number of Ohioans who have tested negative for COVID-19 is 14, according to Tuesday’s update. ODH releases new numbers pertaining to COVID-19 at 2 p.m. daily.

A state call center to answer questions regarding COVID-19 is open seven days a week from 9 a.m. to 8 p.m. at 1-833-4-ASK-ODH (1-833-427-5634).

Summit County Public Health also has set up a call center to answer questions about the illness 8a.m. to 3:30 p.m. Monday through Friday. Call 330-926-5795.

COVID-19 is a respiratory illness with symptoms similar to those of the flu — fever, cough and shortness of breath — that has sickened thousands and killed more than 3,100 in China, according to the World Health Organization. There is not yet a vaccine for COVID-19, nor are there any medications approved to treat it, the Centers for Disease Control and Prevention said.

Ohio State University is immediately suspending all face-to-face instruction until March 30 on its campuses in reaction to the first cases of coronavirus in Ohio.

Here are the latest numbers from across the United States and the world, as of 2 p.m. Tuesday. Statistics about COVID-19 worldwide are from the World Health Organization as of Monday; U.S. numbers are from the CDC as of Tuesday:

Countries, territories and areas with confirmed cases: 105

U.S. jurisdictions reporting cases: 36 (includes the District of Columbia)

Total cases in U.S.: 647

Total deaths in U.S.: 25
