In English, when talking about common viruses people often get,
there are generally two categories: - a cold is generally more
mild and can come with runny nose, sneezing, coughing, sore
throat, etc. - a flu is generally more severe and can bring
fever, chills, fatigue, etc. In my experience with Spanish,
almost all of this tends to be wrapped up in one word: gripe.
What are the official and informal ways of referring to these
diseases? What words exist in Spanish and what varieties of
illness do they refer to? What regional variation exists?
