When a wook has been on festival tour, not showering, sleeping on the ground and acting as a garbage can for drugs and sexual partners, a virus cesspool begins to fester on them, particularly in the dread region of their body. Over the festival season, the viruses on them all grow and combine to develop into a super virus called the wook flu. When a normal concert goer comes into contact with it, they will become deathly ill around 3-4 days after the show. Typically, symptoms include the worst sore throat, aches and headache one has ever felt, which causes the infected person to be bed ridden for up to a week. The only cure is soup, Netflix and the strongest over the counter flu meds one can procure, but a trip to the doctor or emergency room to get antibiotics is not out of the question and is in fact quite common. Unfortunately, a wook flu cure has not been discovered yet, so please plan accordingly if you start feeling ill and have a more experienced concert goer on hand near by to help with your treatment shall you succumb to this terrible virus.
