Cold & Flu

Everyone gets a cold from time to time. More than 200 different viruses can cause a cold, but the rhinovirus is the most common culprit. Its symptoms typically include runny nose and sneezing. It is worth nothing that a cold is not the same as the flu (influenza). Flu symptoms are more severe and can include a fever and shaking chills, aches and pains, lethargy and headaches.
