What needs to be done when a 2 year old gets the epstein-bar virus?

Mononucleosis: Many children who contract the epstein barr virus present with regular cold symptoms and often have rapid recoveries. Those who experience more severe sympstoms often have persistent/recurrent fevers, lack of energy, loss of appetite and irritability. Make sure your toddler eats and drinks well and keep him rested (good luck!). Being a viral infection, no antibiotic will make him recover faster.

Nothing specific: A 2yo tolerates EBV much as they would any other virus. Proper hydration, food and rest as needed will support their system until it passes.
