An ELISA technique for CMV-specific IgM is available, but may give false-positive results unless steps are taken to remove rheumatoid factor or most of the IgG antibody before the serum sample is tested. Because CMV-specific IgM may be produced in low levels in reactivated CMV infection, its presence is not always indicative of primary infection.
About 90% of cases of herpes encephalitis are caused by herpes simplex virus-1 (HSV-1), the same virus that causes cold sores. According to a 2006 estimate, 57% of American adults were infected with HSV-1, [ 3 ] which is spread through droplets, casual contact and sometimes sexual contact, though most infected people never have cold sores.
The two most common forms of herpes are caused by infection with herpes simplex virus (HSV). HSV-1 is typically acquired orally and causes cold sores; HSV-2 is usually acquired during sexual contact and affects the genitals; however, either strain may affect either site. [62] Some people are asymptomatic or have very mild symptoms.
Genital herpes is a herpes infection of the genitals caused by the herpes simplex virus (HSV). [1] Most people either have no or mild symptoms and thus do not know they are infected. [ 1 ] When symptoms do occur, they typically include small blisters that break open to form painful ulcers . [ 1 ]
Nine herpesvirus types are known to primarily infect humans, [7] at least five of which are extremely widespread among most human populations, and which cause common diseases: herpes simplex 1 and 2 (HSV-1 and HSV-2, also known as HHV-1 and HHV-2; both of which can cause orolabial and genital herpes), varicella zoster (VZV or HHV-3; the cause ...
Human herpesvirus 6 (HHV-6) is the common collective name for human betaherpesvirus 6A (HHV-6A) and human betaherpesvirus 6B (HHV-6B). These closely related viruses are two of the nine known herpesviruses that have humans as their primary host.
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 by the type 1 strain of herpes simplex virus (HSV-1) is most common; however, cases of oral infection by the type 2 strain are increasing. [14] Oral HSV-2 shedding is rare, and "usually noted in the context of first episode genital herpes." [21] In general, both types can cause oral or genital herpes. [22] [23] [24]
