Sports people catch infections just like anyone else, however sometimes they are more exposed, particularly in team situations or travelling. Training hard can also weaken the immune system which can make athletes more susceptible to illness. Here we explain some of the more common infections and viruses affecting athletes.

Viral illnesses are usually simply referred to as a virus or viral infection. They occur when a microscopic infectious agent enters the body. Here the virus attacks the body, causing an immune response and illness. When training hard, athletes could be at increased risk of viral infections as their immune system is weakened. Viral infections can be mild or severe, with a range of symptoms.
