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.
Flu symptoms usually start within one to four days after infection. Unlike a common cold, the effects of an influenza virus infection can come on very suddenly. The first signs of the flu are often a fever or chills, accompanied by headache, sore throat, dry cough, runny nose, muscle aches, and fatigue. As the illness progresses, a person may have warm, flushed skin, watery or bloodshot eyes, a severe cough that produces phlegm, and nasal congestion.
