when you are in a photography darkroom and become hyper and giddy for no apparent reason and start to dance and sing
Girl 1: "Oh god, Suzie's got hilary-itis again! She's going crazy in there!"
Girl 2: "I wonder what it is about darkrooms that makes people get so hyper?"

The short-lived bout of flu-like side effects some people get shortly after having the AstraZeneca COVID-19 vaccine.
Symptoms include a fever (of up to 102 degrees), feeling ill, chills, muscle aches, headaches... basically all the flu symptoms. In addition, you may get a raised lump at the jab site. Thankfully, they typically resolve fully within 48 hours, and are a sign your immune system is responding to the vaccine.

"Getting actual COVID-19 is a lot worse than AstraZeneca-itis, so do not skip out on the jab if you're offered it!"

A newly found disease where the infected is slowly suffocated to death, the pain starts in the face and abdomen , then makes you dizzy of low oxygen being passed to the brain and then slow death of suffocation by laughing. The cause is by overly funny friends or some that laughs at anything even some drinking energy drinks. There is no cure for this, at least you die laughing.
(Someone laughing really hard and uncontrollably) oh no she/he got a case of Jemma itis, get away you'll die from laughter if you're infected!
