A major symptom is exhaustion
Headaches are common along with abdominal pain
However nausea and vomiting may occur

I'll allow it

Fatigue may sometimes last for months
But it generally passes within two years
The most prominent sign is often pharyngitis
And puss
A small minority of people spontaneously present a rash
And more puss
Infection is spread! Via saliva

I'll allow it!

And has an incubation period lasting four to six weeks
The length of time an individual remains contagious is unclear
People can still spread the infection for many moths
Possibly up to a year and a half
It mainly affects younger adults
They are likely to experience fever, fatigue and body pains
They may have an enlarged liver and jaundice
People over 40 years of age are more likely to develop serious illness
Mild fever and swollen neck glands may also persist beyond four weeks
The characteristics symptomatology wasn't reported until the late 19th century
Diagnosis... diagnostic criterion is the presence of 50 percent lymphocytes... and... more... puss...
The puss is yellow, sometimes green!
The virus replicates within epithelial cells in the pharynx
And later primarily withing b cells
The exact length of the incubation period is unclear
A review of the literature estimated 33 to 49 days
Onset is often gradual though it can be abrupt
Mononucleosis
