|"Is this all real? Or has this been happening inside my head?"
The subject of this article is of a real-life person, place, group, company, product, or creative work that has been mentioned "in-universe" in a canon source. The Harry Potter Wiki is written from the perspective that all information presented in canon is true (e.g., Hogwarts really exists), and, as such, details contained in this article may differ from real world facts.

Flu is an acute contagious disease of the upper airways and lungs, caused by a virus, which rapidly spreads around the world in seasonal epidemics. The most common symptoms of the disease are chills, fever, sore throat, muscle pains, severe headache, coughing, weakness/fatigue and general discomfort.
On 1 September, 1992, when Harry Potter and Ronald Weasley flew a Ford Anglia to Hogwarts Castle (a breach of the International Statute of Wizarding Secrecy), they accidently caused Felicitania Tugwood to fall from her broomstick straight into the River Mersey. She got a "shocking" case of flu.
In late October, 1992, Argus Filch got the flu, and as a result, walked about wheezing and wild-looking, with a thick tartan scarf around his head, and his nose unusually purple. In September, 1993, Sybill Trelawney predicted classes would be interrupted in the following February due to a nasty bout of flu, in which she would lose her voice herself, which appeared not to correspond with what really happened.
