Herpes simplex labialis, also known as cold sores, is a common cause of perioral discomfort. Herpes simplex labialis is usually caused by the herpes simplex virus, type 1 (HSV-1), whereas the most common causative agent of genital herpes is herpes simplex, type 2 (HSV-2). HSV-1 infection is ubiquitous, with 600,000 new cases developing each year.4 There is no cure, so an initial infection remains, without exception. Patients may wish to understand how HSV-1 was contracted, in the hope that their family members or significant others avoid the disease.
Approximately one third of patients who experience the initial HSV-1 lesion undergo recurrences.
The pharmacist can refer patients with an active case of HSV-1 to the physician for an antiviral, such as Zovirax or Denavir. Both type-specific and nonspecific antibodies to HSV develop during the first several weeks following infection and persist indefinitely. The sensitivities of these tests for detection of HSV-2 antibody vary from 80% to 98%, and false-negative results may occur, especially in the early stages of infection. Clinical manifestations of genital herpes differ between the first and recurrent outbreaks of HSV. The signs and symptoms of the first episode or a recurrence are identical for both viral types. Median recurrence rate after a symptomatic first episode is: Type 1 herpes simplex virus is the usual cause of cold sores around the mouth. However, in some cases type 1 can recur spontaneously in the eye, causing ocular herpes, a potentially serious infection which can lead to blindness. This condition affects millions of Americans and is the source of numerous patient inquiries to pharmacists.
The epidemiologic conclusion to be drawn from a medical condition with this natural history is that the prevalence can only increase with the age of a given population group. Lysine is a standard remedy recommended by health food stores but lacks evidence of any effect on cold sores. However, packages also disclose that it contains salicylic acid as an "inactive ingredient." Salicylic acid is highly active in eroding surface skin, depending on the concentration. This recurrent, incurable disease remains undiagnosed in most infected persons; they often have mild or asymptomatic infections and shed virus intermittently in the genital tract.
However, many patients with herpes simplex virus type 2 infections have no signs or symptoms of the disease. Isolation of HSV in cell culture is the preferred virologic test in patients who have genital ulcers or other mucocutaneous lesions. Because false-negative HSV cultures are common, especially in patients with recurrent infection or healing lesions, these tests are useful in confirming a clinical diagnosis of genital herpes.
Accurate type-specific assays for HSV antibodies must be based on the HSV-specific glycoprotein G2 for the diagnosis of HSV-2 infection and glycoprotein G1 for HSV-1 infection. Genital herpes is an infection caused by either the Type 1 (HSV-1) or Type 2 (HSV-2) herpes simplex virus.
Conclusions: The authors found that, in the United States, recurrent genital HSV-1 is relatively rare in the STD and HIV clinic setting, especially among black people. Pharmacists should be able to recognize the condition, explain its etiology, and fully describe the various options for prevention and treatment. HSV-1 establishes nonreplicating dormancy in the nerve that innervates the area where the lesion developed, most often the trigeminal ganglion.3 Investigators have not fully elucidated the triggers that allow the virus to emerge from its dormant condition to cause a recurrence.


Docosanol 10% cream (Abreva) is a primary product among them, containing the inactive ingredients benzyl alcohol and light mineral oil.
Novitra is a cream with homeopathically diluted zinc oxide that also lacks safety and efficacy data.

Although systemic antiviral drugs can partially control the signs and symptoms of herpes, they do not eradicate latent virus and have no effect on recurrence after therapy is discontinued.
Many infected persons do not have the typical painful multiple vesicular or ulcerative lesions (Figure 1). The sensitivity of culture declines rapidly as lesions begin to heal, usually within a few days of onset. They can also be used to diagnose asymptomatic infection and to test sex partners of infected patients.
These assays became available in 1999; older assays do not accurately distinguish HSV-1 from HSV-2 antibody. False-positives can occur, especially in patients with a low likelihood of HSV infection, and a second test may be required.
It can also be caused by herpes simplex virus type 1, which is the cause of oral herpes (cold sores on the mouth and lips). According to the Lafferty study, genital HSV-2 infections were the most frequently recurring herpes infections, followed by oral HSV-1, genital HSV-1, and last of all, oral HSV-2.
Several separate blisters may appear to coalesce as more blisters appear in the intervening spaces.1,8 At the end of this stage, the lips may be virtually disfigured by a large crop of blisters.
Thus, patients must be constantly attentive to the techniques that help prevent transmission.
Furthermore, they must avoid oral contact with anything that might touch the lips or skin of another person before it is decontaminated.
It is the only FDA-approved nonprescription product able to shorten healing time and duration of symptoms, such as tingling, pain, burning, and itching.15 Docosanol is optimally applied during the prodrome stage at the first sensation of tingling but will still be helpful if the patient waits until a later stage. Releev contains benzalkonium chloride, an antiseptic agent not proven safe or effective for cold sores.
In those conditions, the stratum corneum (upper epidermal layer) is hyperkeratotic, and salicylic acid safely erodes the abnormally thickened skin.
Thus, laboratory testing is necessary to confirm the diagnosis and to determine the HSV serotype. Polymerase chain reaction assay for HSV DNA is the test of choice for detecting HSV in the spinal fluid of patients with suspected CNS involvement. Routine screening for HSV infection in the general population, however, is not recommended.
Figure 1 shows the relative proportions of genital HSV-1 and HSV-2 isolates in initial and recurrent infections among heterosexual men, MSM, and heterosexual women. After approximately two days, the blisters begin to rupture, exposing an erythematous open wound that becomes gray in color.8 This is the weeping stage. They must avoid sharing such objects as drinking glasses, coffee mugs, straws, washcloths, towels, spoons, forks, lip balms, and medication dosing devices.
This product, applied five times daily to the face and lips in patients 12 and older, prevents fusion between plasma membranes and the HSV-1 virus envelope, reducing the risk of intracellular entry with subsequent viral replication.
Yet, since the lips have little or no stratum corneum, Carmex could cause damage if used for cold sores.


There are two distinct types of the virus, herpes simplex virus type-1 (HSV-1) and herpes simplex virus type-2 (HSV-2) , both of which are closely related a-herpesviruses (having a broad host range). Until the manufacturer discloses the concentration of salicylic acid in the product, its safety cannot be verified and the product should not be recommended. Although HSV-1 causes up to 30% of the first episodes of genital herpes, recurrences are much less common with HSV-1 infection than with HSV-2 infection. Reactivation causes recurrent disease (oral or genital herpes) , but most often it leads to shedding of infectious virus from the skin or mucous membranes, thus leading to further transmission of the virus. The wounds are covered with yellowish crusts in the scabbing stage, which lasts for two to three days.
They must refrain from touching the lesions, since they may transfer the virus to their hands. Patients should rub the cream in gently and completely and wash their hands both before and after application.
The skin beneath the scabs continues to be painful and pruritic, and the scabs begin to break and bleed. During a typical day, the hands contact hundreds of surfaces, and the virus could reach an object that is picked up by another person. There are two main types of herpes simplex virus (HSV) ; type 1, which is mainly associated with facial infections and type 2, which is mainly genital, although there is considerable overlap.
Lesions should be washed gently with soap and water, but the washcloth used should be laundered immediately after contact, as it is also infective.
If the lesion worsens or fails to disappear after 10 days of use, the patient should discontinue use and seek a physician. The recurrence rate is usually much lower in those whose genital infections are caused by HSV-1.
Secondary scabs become progressively smaller and slowly slough to reveal pink skin that gradually assumes the appearance of the surrounding unaffected epidermis.1,8 The disease seldom leaves permanent scars. It may be worthwhile to advise patients to utilize a one-time use towel that can be discarded to further reduce the chance of cross-infection. Oral HSV-2 normally recurs much less often than HSV-1, statistically about once every ten years. HSV-1 normally is associated with oral infections and HSV-2 with genital infections, but either type can infect a person anywhere on the skin.
I was recently diagnosed with genital hsv-1 and had my first noticeable outbreak 6 weeks ago.
However, it can cause recurrent painful sores and can be severe for people with suppressed immune systems. HSV-1 infection in the genital area usually causes a significant first episode, about one recurrence per year and a lower rate of unrecognized recurrences. Genital herpes, often simply known as herpes, may have minimal symptoms or form blisters that break open and result in small ulcers.
People who have recurrent genital herpes (repeated episodes) can transmit the herpes virus between recurrences (through asymptomatic shedding).
Genital herpes is caused by a virus, the Herpes Simplex Virus (HSV -mostly type 2sometimes type 1which usually causes infection of the lips and mouth). The risk of transmission is low ( 1 ) in recurrent herpes lesions present at delivery or if the genital HSV infection is acquired during the first half of the pregnancy.
