HSV – herpes simplex virus (type 1 and 2)
Diagnostics if infections caused herpes simplex virus (HSV type 1 and 2).
What is HSV?
HSV is herpes simplex virus. Two closely related types of this virus exist: HSV-1 and HSV-2, which differ mainly in epidemiology. Both types of the virus can reproduce in nervous system and change into the latency condition. The characteristic feature of herpes simplex virus is also the ability of reactivation as a result of influence of such inducing factors as fever, psychic stress, injury or menstruation.
How is HSV transmitted?
The infection with herpes viruses is extremely common. HSV is transmitted by means of direct contact with disease changes located in oral cavity, on face skin and in the areas of sexual organs.
What diseases are caused by HSV?
Both types of herpes viruses are able to cause changes on skin and mucous membranes both in the areas of sexual organs and oral cavity. Even 80% of all HSV infections proceed without any symptoms.
The most common is type 1 of herpes virus connected with development of not dangerous vesicular changes on skin and mucous membranes of oral cavity. Particularly persistent and difficult to cure are ophthalmic infections caused by HSV-1.
On the other hand, HSV-2 most often infects the areas of sexual organs. HSV infections, especially with type 2, can be dangerous to pregnant women. During birth, the infant can get infected and the infections concern many organs: brain, eyes, internal organs. Infection by HSV type 2 with symptoms in the mother is an indication to end pregnancy by caesarean section.
Herpes viruses may cause also neurological infections which are particularly dangerous for people in primary or secondary immunosuppression.
Diagnostics of HSV infections
Early and reliable diagnostics of clinical samples collected locally from the changes allows us to begin appropriate treatment. In order to detect herpes virus, cell cultures or serological tests are used. HSV diagnostics based on PCR method ensures a shorter time of obtaining the result, as well as higher sensitivity and specificity compared to culture-based methods. The test using PCR technique, enabling detection of viruses in cerebrospinal fluid, is currently regarded as a golden standard in diagnostics of central nervous system diseases. Molecular tests allow us also to detect the virus in the phase of asymptomatic viral shedding.
