What is Herpes Simplex Virus test?
Herpes simplex virus or HSV is the causative agent of herpes. There are two different types of HSV- HSV1 that causes oral sores and HSV2 that chiefly affects genital organs. The virus enters the body through injured skin, mucus secretion in the mouth and sexual contact.
In the first stage of the infection (primary stage), patients present with fever, soreness in the throat and mouth or painful boil or eruptions in the genital organs. In the second stage, the infection becomes inactive and the virus continues to survive throughout the life in the spinal cord. However, a latent infection can reactivate any time during periods of stress, due to an injury, immunosuppressive diseases such as cancer and AIDS, exposure to sunlight, or during monthly periods in women.
HSV is transmitted from an infected mother to the baby during delivery or before birth leading to congenital herpes and birth defects in the baby’s brain and central nervous system.
Various tests are used for the detection of HSV in the body. These include blood tests, viral culture test and antibody test. A polymerase chain reaction or PCR is sometimes suggested to differentiate HSV eruptions from other types of vascular eruptions and to differentiate between HSV1 and HSV2 infections.
