Some people become infected with EBV but do not develop symptoms. This is called a subclinical infection. How long do the symptoms last? The glandular fever symptoms usually resolve by themselves within two to three weeks of the initial infection. Initial three to five days will be the worst followed by improvement in a gradual course. The fever usually lasts for 10 to 14 days and declines in severity after the initial three to five days. Fatigue however may persist for up to three to six months. Normal activity may be resumed within one to two months of the infection. In young children the onset of the glandular fever is usually short term.
