Mononucleosis is caused by the Epstein-Barr virus (EBV), which is spread through saliva. This can happen through:
* Direct contact: Kissing, sharing utensils, or close contact with an infected person.
* Indirect contact: Sharing drinks, food, or objects contaminated with saliva.
Cats do not carry EBV. They can carry other viruses and bacteria that can be harmful to humans, but not mononucleosis.
However, cats can spread other infections through saliva, such as:
* Toxoplasmosis: A parasitic infection that can be serious for pregnant women.
* Cat scratch fever: A bacterial infection that can cause swollen lymph nodes.
* Ringworm: A fungal infection that can cause skin lesions.
Therefore, it's always a good idea to wash your hands thoroughly after petting a cat and to avoid letting them lick your face or open wounds.
