Seasonal influenza, or ‘the flu’, is a common illness that spreads easily. It affects your nose, throat, and lungs and you can have systemic symptoms such as fever and muscle aches. You can catch the flu from tiny droplets when someone with the flu coughs or sneezes. You can also get it by touching surfaces with flu virus droplets and then touching your eyes, nose, or mouth.

Respiratory Syncytial Virus (RSV) is a respiratory virus that infects the nose, throat, and lungs resulting in cold-like symptoms. It usually starts spreading in the fall and peaks in the winter months. RSV infection can happen at any age but is particularly severe in infants and older adults, and can cause significant lung infections requiring hospitalization especially in those with underlying health conditions such as asthma, chronic heart or lung disease, and those with weakened immune systems.

The ‘common cold’ is caused by viruses (germs) that infect the nose, throat and sinuses causing upper respiratory tract infections. Colds are most common in the fall and winter when people are indoors and in close contact with each other. They're so common in fact that it's normal for children under five years old to have as many as 12 upper respiratory tract infections (URTIs) in one year. Upper respiratory tract infections, like colds, cause symptoms in the nose, throat and sinuses. There is no vaccination available for the common cold. See this helpful video on ways to beat the common cold at home. You can also find more information on CHEO’s webpage.
