Democratic Texas Senate nominee James Talarico has suspended in-person campaign events as he battles the flu and a fever, forcing the candidate to shift his campaign appearances online as the November election approaches.

Talarico participated remotely in an interview with the U.S. Hispanic Business Council in the Rio Grande Valley after coming down with the flu, preventing him from appearing in person.

“I guess I’ve shaken too many hands on the campaign trail,” Talarico said during the virtual appearance.

The temporary suspension comes as Talarico is trying to maintain his campaign schedule across Texas in the race against Republican nominee Ken Paxton. Rather than appearing in person, Talarico is continuing some campaign activity remotely while he recovers.

The illness puts a pause on the kind of face-to-face campaigning that is particularly important during a statewide Senate race, where candidates are expected to travel extensively and meet voters across a massive state.

His campaign has not said how long he expects to remain off the in-person campaign trail.

For now, the Democratic nominee is campaigning from a distance while dealing with the illness, leaving his campaign to rely on virtual appearances until he is able to resume traveling and holding events in person.
