Doctors make the worst patients, as evidenced by the newest sneak peek for Grey's Anatomy Season 10, Episode 18 — "You Be Illin'," airing April 3.

As you can see, Jackson (Jesse Williams) falls victim to the flu spreading like wildfire throughout Grey Sloan Memorial Hospital. (We already saw Derek collapse from the virus!)

As the sneak peek begins, Jackson emerges from a patient room, declaring that the poor little one inside has a "Pott's puffy tumor" — which is a goofy-sounding name for a very-serious infection around the skull that can cause swelling outward and inward, endangering the brain.

"You look horrible," April (Sarah Drew) observes. And she's right, Jackson looks clammy and pale and has bags under his eyes.

Bailey (Chandra Wilson) agrees with Dr. Kepner's assessment: "Yeah, correct. You look horrible. What's going on with you?"

"Oh, nothing," Jackson responds. "My stomach's a little screwy. I'm fine. I'm gonna go book an OR, though…"

"No, you're not," April argues. "The best thing you can do for this kid is to be nowhere near him."

"Because you look horrible," adds Bailey. "Yeah, I can drain a Pott's puffy tumor. Go home!"

But just like his McDreamy colleague, Jackson stubbornly refuses to take some downtime. Not sure we'd wanna be patients at this particular hospital at this time!

Grey's Anatomy Season 10, Episode 18 — "You Be Illin'" — airs Thursday, April 3, at 9 p.m. ET on ABC.
