Guide To The Most Common Respiratory Illnesses

Common Cold

The common cold occurs when a virus causes an infection in the throat and nose. The majority of cases are harmless, though they can cause discomfort. A large number of viruses can cause the common cold. Children younger than six years old are the most likely to contract colds. A healthy adult will usually contract anywhere from two to three colds in a year. The average common cold resolves in seven to ten days.

The first cold symptoms will generally appear within three days of exposure to the virus. Symptoms include a sore throat, congestion, sneezing, stuffy or runny nose, mild headache, low-grade fever, and general feelings of unwellness. Patients should seek medical attention if their fever is higher than 101 degrees Fahrenheit. Individuals who smoke are more likely to have long-lasting symptoms. A doctor should evaluate cold symptoms that do not improve.
