Infectious mononucleosis (IM, mono), also known as glandular fever, is an infection usually caused by the Epstein–Barr virus (EBV). [2] [3] Most people are infected by the virus as children, when the disease produces few or no symptoms. [2] In young adults, the disease often results in fever, sore throat, enlarged lymph nodes in the neck, and ...
There are several forms of Epstein–Barr virus (EBV) infection. These include asymptomatic infections, the primary infection, infectious mononucleosis, and the progression of asymptomatic or primary infections to: 1) any one of various Epstein–Barr virus-associated lymphoproliferative diseases such as chronic active EBV infection, EBV+ hemophagocytic lymphohistiocytosis, Burkitt's lymphoma ...
After its initial entry into B cells, the Epstein–Barr virus infects other B cells and in doing so may or may not cause a symptomatic disease viz., infectious mononucleosis. In either case, the virus soon switches to its dormant, viral latency 0 phase within memory B cells and the infected individual becomes an asymptomatic, lifelong EBV ...
The mononuclear spot test or monospot test, a form of the heterophile antibody test, [1] is a rapid test for infectious mononucleosis due to Epstein–Barr virus (EBV). It is an improvement on the Paul–Bunnell test. [2] The test is specific for heterophile antibodies produced by the human immune system in response to EBV infection.
Reactive lymphocytes have been found to accumulate in areas of inflammation like the liver and pharynx of individuals with infectious mononucleosis and skin window preparations. In infectious mononucleosis, the atypical lymphocytes are one component of a normal immune system that helps to control potentially fatal Epstein-Barr virus -induced B ...
When infection occurs during adolescence or young adulthood, it causes infectious mononucleosis 35 to 50% of the time. [22] EBV infects B cells of the immune system and epithelial cells. Once EBV's initial lytic infection is brought under control, EBV latency persists in the individual's memory B cells for the rest of their life. [19] [23] [24]
Fun fact: B/Yamagata strains haven’t been detected since the COVID-19 pandemic began, so flu B is technically down to just B/Victoria right now. On the whole, flu A viruses tend to cause a more ...
[1] [2] The virus establishes latent infection and causes infectious mononucleosis. There is also increasingly more evidence that EBV may be a trigger of multiple sclerosis. [3] It is a dual-tropic virus, meaning that it infects two different host cell types — in this case, both B cells and epithelial cells.
