The cancellations on Tuesday marked the first instances in which presidential campaigns have called off events due to the coronavirus outbreak.

The moves come amid heightened concerns over the potential for the disease, known as COVID-19, to spread at crowded, indoor events.

So far, three cases of novel coronavirus have been confirmed in Ohio. Earlier on Tuesday, Ohio Gov. Mike DeWine (R) asked that indoor sporting events only be attended by athletes, parents and “others essential to the game.”

For Trump, Biden and Sanders, the threat of becoming ill is all the more serious. Not only do they regularly attend political gatherings across the country, but all three candidates are in their 70s, and early data suggests that older people are more likely to experience serious illness when infected with the virus.
