Can you swim when have mononucleosis?

No, it is not advisable to swim when you have mononucleosis.

Mononucleosis, also known as "mono," is a common contagious disease caused by the Epstein-Barr virus. While swimming itself does not pose a direct risk of transmitting or contracting mono, there are several reasons why it's generally recommended to avoid swimming while ill with mononucleosis:

1. Fatigue and weakness: Mono can cause extreme fatigue and weakness, which can impair your coordination, balance, and judgment. This can increase the risk of accidents or injuries while swimming.

2. Swollen lymph nodes: Mononucleosis is characterized by swollen lymph nodes, particularly in the neck and throat. Engaging in physical activities like swimming can put pressure on these swollen lymph nodes and cause discomfort or pain.

3. Compromised immune system: Mononucleosis affects the immune system, making individuals more susceptible to other infections. Swimming in public pools or natural bodies of water can expose you to a variety of microorganisms that could further compromise your already weakened immune system.

4. Potential complications: Mononucleosis can lead to complications such as spleen enlargement and, in rare cases, rupture of the spleen. Engaging in strenuous activities like swimming while the spleen is enlarged can increase the risk of injury or complications.

Therefore, it's essential to rest and allow your body to recover when you have mononucleosis. Once you have fully recovered and your doctor has cleared you for physical activity, you can resume swimming and other regular activities.
