Research has shown that, depending on the method used to detect the virus, anywhere from 20%-80% of people who have had mononucleosis and have recovered will continue to secrete the EBV in their saliva for years due to periodic "reactivations" of the viral infection.
Since healthy people without symptoms also secrete the virus during reactivation episodes throughout their lifetime, isolation of people infected with EBV is not necessary.
Most people have been exposed to the virus as children, and as a result of the exposure, they have developed immunity to the virus.
This means that most people, sometime in their lives, have been infected with EBV.
Having a sore throat can be a symptom of many conditions, and many people wonder if their own sore throat might be a sign of something more serious than the common cold.
Specifically, infectious mononucleosis ("mono") and infection with Streptococcus bacteria ("strep throat") are two conditions that both produce an extremely painful sore throat.
When infection occurs in childhood, the virus most often produces no symptoms.
It is estimated that only about 10% of children who become infected with EBV develop the illness.
Mono is confirmed by blood tests that may also include tests to exclude other possible causes of the symptoms, such as tests to rule out strep throat.
