Apple cofounder Steve Wozniak took to Twitter this afternoon to suggest that he and his wife “may have both been patient zero” for coronavirus in the United States. As it turns out, this wasn’t the case.

Woz’s tweet came in the form of a Swarm check-in at the West Coast Sports Institute in Santa Clara. The accompanying message read that the couple was there “checking out Janet’s bad cough,” which apparently started on January 4 after they returned from China.

But in an email to USA Today following Wozniak’s irresponsible tweet, Janet Wozniak said that she has a sinus infection, not coronavirus:

To take to Twitter and suggest that he and his wife “may have been patient zero” for coronavirus in the United States is an alarming thing for Wozniak to do. Equally irresponsible is their apparent decision to wait two months to get checked out after returning from China with a “bad cough.” Of course, there is also the possibility that this was just a really bad joke on Woz’s part.

The CDC has a full explainer on what you should know about coronavirus on its website.
