A doctor will base a presumptive diagnosis on information provided by the patient and on the physical examination. The characteristic appearance of the herpes sores leaves little doubt about the diagnosis, so the typical appearance of the sores is key to the diagnosis. This appearance helps distinguish oral herpes from oral thrush, shingles, gonorrhea, and syphilis. In addition, chapped or sunburned lips can resemble oral herpes, but the tissue stain (Tzanck smear, see below) shows no virus-induced cell changes. Further testing is usually not necessary but is sometimes done.
The herpes virus can be shed from an infected person even when there are no lesions visible. So caution is important. Some may wish to take the daily prophylactic oral drug Valtrex (an antiviral oral medication) to help cut down on shedding. Herpes can also be transmitted on any skin: fingers, lips, etc. Depending on sexual practices, herpes simplex can be transferred to genitals and or buttocks from the lips of someone who has fever blisters. Honesty between partners is very important so these issues can be discussed openly.
Laboratory testing is often used to confirm a diagnosis of genital herpes. Laboratory tests include culture of the virus, direct fluorescent antibody (DFA) studies to detect virus, skin biopsy, and polymerase chain reaction to test for presence of viral DNA. Although these procedures produce highly sensitive and specific diagnoses, their high costs and time constraints discourage their regular use in clinical practice.
HSV asymptomatic shedding occurs at some time in most individuals infected with herpes. It can occur more than a week before or after a symptomatic recurrence in 50% of cases. Virus enters into susceptible cells by entry receptors such as nectin-1, HVEM and 3-O sulfated heparan sulfate. Infected people who show no visible symptoms may still shed and transmit viruses through their skin; asymptomatic shedding may represent the most common form of HSV-2 transmission. Asymptomatic shedding is more frequent within the first 12 months of acquiring HSV. Concurrent infection with HIV increases the frequency and duration of asymptomatic shedding. Some individuals may have much lower patterns of shedding, but evidence supporting this is not fully verified; no significant differences are seen in the frequency of asymptomatic shedding when comparing persons with one to 12 annual recurrences to those with no recurrences.
Although it's rare, pregnant women can pass on the herpes infection to their child. This can result in a serious and sometimes deadly infection in the baby. That's why taking steps to prevent an outbreak at time of delivery is recommended starting at 34 weeks into the pregnancy. If you have signs of an active viral infection when it's time to deliver, your doctor will likely recommend a cesarean section for delivery.
Genital herpes is so common. It’s affecting more than 3 million Americans each year. And 1 out of 5 people is estimated to have this disease at some point in their lives. Your partner can also have the chances of contracting genital herpes. Many people may be shocked and disappointed when their partners have this disease. But, remember that people with genital herpes really need acceptance and support. Here’s what you should do when you find out your partner has genital herpes.
The HSV viruses multiply in the human cell by overtaking and utilizing most of the human cells functions. One of the HSV steps in multiplication is to take control of the human cell's nucleus and alter its structure. The altered nucleus (enlarged and lobulated or multinucleated) is what actually is used to help diagnose herpes simplex infections by microscopic examination. The reason sores appear is because as they mature the many HSV particles rupture the human cell's membrane as they break out of the cell.
The risk of transmission from mother to baby is highest if the mother becomes infected around the time of delivery (30% to 60%), since insufficient time will have occurred for the generation and transfer of protective maternal antibodies before the birth of the child. In contrast, the risk falls to 3% if the infection is recurrent, and is 1–3% if the woman is seropositive for both HSV-1 and HSV-2, and is less than 1% if no lesions are visible. Women seropositive for only one type of HSV are only half as likely to transmit HSV as infected seronegative mothers. To prevent neonatal infections, seronegative women are recommended to avoid unprotected oral-genital contact with an HSV-1-seropositive partner and conventional sex with a partner having a genital infection during the last trimester of pregnancy. Mothers infected with HSV are advised to avoid procedures that would cause trauma to the infant during birth (e.g. fetal scalp electrodes, forceps, and vacuum extractors) and, should lesions be present, to elect caesarean section to reduce exposure of the child to infected secretions in the birth canal. The use of antiviral treatments, such as aciclovir, given from the 36th week of pregnancy, limits HSV recurrence and shedding during childbirth, thereby reducing the need for caesarean section.
Most people with genital herpes have no symptoms, have very mild symptoms that go unnoticed, or have symptoms but do not recognize them as a sign of infection. Genital herpes symptoms include blisters, sharp pain or burning feelings if urine flows over sores, an inability to urinate if severe swelling of sores blocks the urethra (tube from the bladder to outside the vagina), itching, open sores, and pain in the infected area.
HSV-1 infections can be treated with antiviral medication, such as acyclovir. These medication cannot cure the infection. But, they can help reduce the severity and frequency of symptoms. Prosurx is one of the best antiviral creams for cold sores. It is famous for treating symptoms and preventing outbreaks in the future. For this, you are recommended to apply Prosurx to the sores 2 to 3 times a day. Factors like stress, colds, fever and certain foods may trigger HSV-1 infections. To prevent an outbreak, you need to avoid these triggers.
The herpes simplex virus is probably the most well-known virus of the herpes family, and it is just as contagious. Herpes simplex infects epithelial cells and remains latent in neurons. HSV-1 causes recurrent oropharyngeal lesions, commonly known as “fever blisters" or "cold sores.” It is also the primary cause of sporadic encephalitis (inflammation of the brain), gingivostomatitis (inflammation of the gums and mucous lining of the mouth), and keratoconjunctivitis (severe dryness of the eye that involves the cornea) and dendritic corneal ulcers (also called HSV keratitis) in which the cornea becomes affected by herpetic lesions that look like the dendrites of neurons in the brain.
Although herpes treatment is helpful, there is no cure. However, in most cases, outbreaks become fewer, less painful, and weaker over the course of a few years. If you have herpes, you can take certain medications to help manage the infection. Using herpes treatments is usually very effective in speeding up the healing of sores and preventing them from returning frequently.
