What is colds and flu?


Colds and flu are both respiratory illnesses caused by viruses, but they are different in terms of their symptoms and severity.

The common cold is usually caused by the rhinovirus, although other viruses can also be responsible. Symptoms of a cold may include a runny or stuffy nose, coughing, sneezing, sore throat, and mild fever. While a cold can be annoying and uncomfortable, it is usually a mild illness that goes away on its own within a week or two.

Influenza, commonly known as the flu, is a more severe respiratory illness caused by the influenza virus. Symptoms of the flu can include a sudden onset of fever, chills, muscle aches, coughing, and fatigue. Unlike a cold, the flu can be a serious illness that can lead to complications such as pneumonia, especially in vulnerable populations such as the elderly or those with weakened immune systems.

Both colds and flu are contagious and can spread from person to person through the air or through contact with contaminated surfaces. It is important to practice good hygiene such as washing hands frequently, covering coughs and sneezes, and staying home when sick to prevent the spread of these illnesses.
