Word story Expand. Hypochondriac comes ultimately from the Greek word hypokhondria, which literally means âunder the cartilage (of the breastbone).â In the late 16th century, when hypochondriac first entered the English language, it referred to the upper abdomen.
Cold symptoms usually begin with a sore throat, which usually goes away after a day or two. Nasal symptoms, runny nose, and congestion follow, along with a cough by the fourth and fifth days. Fever is uncommon in adults, but a slight fever is possible.
People also catch the flu by touching surfaces with the virus on them and then touching their eyes, nose or mouth. After exposure to the flu virus, many people begin to experience symptoms within one to seven days. The flu often spreads rapidly within groups, reports MedlinePlus. Once it arrives in a school, students get sick within two to three weeks. A high fever, between 102 and 106 degrees Fahrenheit, is often the first sign of the flu.
