The skin heals without scarring within six to ten days. The appearance of genital herpes is somewhat different. The blisters formed in the genital area also begin as small red bumps that fill with liquid. In dry areas, the blisters form a scab and heal within two to three weeks. In moist areas, the blisters usually break and form painful ulcers before healing. New blisters may form over a period of a week or longer. They may then join to form very large ulcers open sores. The pain usually disappears after about two weeks. The blisters and ulcers heal without scarring in three to four weeks.
Both forms of herpes tend to recur on a regular basis. In the case of cold sores, most people experience fewer than two outbreaks each year. This pattern varies considerably, however. Some people never have a second episode of cold sores, while others have many such episodes.
Those who do have further outbreaks usually get blisters in the same area each time. They also tend to be triggered by the same factors, such as stress or exposure to sun. Genital herpes tends to recur more often than cold sores. About 40 percent of persons infected with HSV2 will experience six or more outbreaks per year. The vast majority of patients with genital herpes will have at least one outbreak every year.

Reoccurrences of HSV2 infections tend to be less severe than the initial outbreak. Patients usually have fewer blisters and less pain. The time between outbreak and healing may also get shorter with each outbreak. Cold sores and genital herpes both have a very distinctive appearance. Simple observation of a patient's symptoms often provides a strong indication of the problem. However, the symptoms of the two diseases are somewhat similar to those of other infections.
Cold sores, for example, look something like a bacterial infection known as impetigo. There may also be some confusion between cold sores in the mouth and canker sores. A variety of diseases cause sores in the genital area also. Some examples include syphilis, chancroid, herpes zoster another infection caused by the herpes virus , and inflammatory bowel disease.
In some cases, it is difficult to distinguish the blisters and ulcers caused by genital herpes and sores produced by other diseases. To confirm a diagnosis, a doctor can do a culture of cells taken from the infected area by wiping a clean cotton swab over the infected area. The material collected on the swab is then kept in a warm, moist environment for a few days.
The organisms responsible for the infection can be identified when examined under a microscope. There is no cure for herpes virus infections. However, there are antiviral drugs that can relieve some symptoms of these infections. Antiviral drugs interfere with the growth of viruses. They work best when used as early in an infection as possible. For the best results, treatment should begin during the prodrome stage of infection. Antiviral drugs may also prevent future outbreaks of cold sores or genital herpes.
The preferred antiviral for treatment of herpes infections is acyclovir trade name Zovirax. The drug is most effective when injected directly into the bloodstream or taken orally by mouth. It can also be used as a lotion and applied directly to sores, but it is less effective when used this way. Treatments are also available to relieve the symptoms of herpes infections. Patients with cold sores should avoid salty foods, citrus foods, and other foods that irritate the sores. The sores can be washed once or twice a day with warm, soapy water.
Over-the-counter medications that contain the chemical phenol can provide some relief too. Blistex Medicated Lip Ointment is an example of this kind of medication. Aspirin, acetaminophen, or ibuprofen can also be used to relieve the pain of cold sores. Children, however, should not take aspirin as it can cause Reye's syndrome see Reye's syndrome entry. There are several things a patient can do to reduce the pain of genital sores. Wearing loose-fitting clothing and cotton underwear is helpful.
Soaking in a tub of warm water and using a blow-dryer set on the cool setting to dry the infected area may help.

Ann Intern Med ; 10 — Persons with a chronic medical condition may be vaccinated unless a contraindication or precaution exists for the condition see Contraindications and Precautions to Vaccination. A subsequent clinical study did not find a significant increase in the incidence of zoster among persons who received zoster vaccine and PPSV23 at the same visit compared with persons who received the vaccines 30 or more days apart.
Consequently, to avoid introducing barriers to patients and providers who are interested in these two important vaccines, CDC has not changed its recommendation for either vaccine, and continues to recommend that zoster vaccine and PPSV be administered at the same visit if the person is eligible for both vaccines. ACIP recommends the vaccine for postexposure prophylaxis in persons who do not have evidence of varicella immunity. If exposure to varicella does not cause infection, postexposure vaccination should induce protection against subsequent exposure.
If the exposure results in infection, there is no evidence that administration of varicella vaccine during the incubation period or prodromal stage of illness increases the risk for vaccine-associated adverse reactions. Although postexposure use of varicella vaccine has potential applications in hospital settings, preexposure vaccination of all healthcare personnel without evidence of varicella immunity is the recommended and preferred method for preventing varicella in healthcare settings. Varicella outbreaks in some settings e. Varicella vaccine has been used successfully to control these outbreaks.
The ACIP recommends a second dose of varicella vaccine for outbreak control. During a varicella outbreak, persons who have received one dose of varicella vaccine should receive a second dose, provided the appropriate vaccination interval has elapsed since the first dose 3 months for persons aged 12 months through 12 years and at least 4 weeks for persons aged 13 years of age and older.
MMRV vaccine may be used as described for varicella vaccine, and for measles as described in the Measles chapter. Exposure to a person with either primary varicella chickenpox or herpes zoster does not cause zoster in the exposed person. Herpes zoster vaccine has no role in the postexposure management of either chickenpox or zoster and should not be used for this purpose. In , the ACIP published a revised definition for evidence of immunity to varicella. Evidence of immunity to varicella includes any of the following:. Contraindications and precautions are similar for all varicella-containing vaccines.
Persons with a severe allergic reaction anaphylaxis to a vaccine component or following a prior dose of vaccine should not receive varicella vaccine. Varicella, MMRV, and zoster vaccines all contain minute amounts of neomycin and hydrolyzed gelatin but do not contain egg protein or preservative. Persons with immunosuppression due to leukemia, lymphoma, generalized malignancy, immune deficiency disease, or immunosuppressive therapy should not be vaccinated with a varicella-containing vaccine.
Persons whose immunosuppressive therapy with steroids has been discontinued for 1 month 3 months for chemotherapy may be vaccinated. Single-antigen varicella vaccine may be administered to persons with impaired humoral immunity e. However, the blood products used to treat humoral immunodeficiency may interfere with the response to vaccination.
Recommended spacing between administration of the blood product and receipt of varicella vaccine should be observed see Chapter 2, General Recommendations on Immunization , for details. Persons with moderate or severe cellular immunodeficiency resulting from infection with human immunodeficiency virus HIV , including persons diagnosed with acquired immunodeficiency syndrome AIDS should not receive varicella vaccine. Women known to be pregnant or attempting to become pregnant should not receive a varicella-containing vaccine. To date, no adverse outcomes of pregnancy or in a fetus have been reported among women who inadvertently received varicella vaccine shortly before or during pregnancy.
The ACIP recommends prenatal assessment and postpartum vaccination for varicella. Women should be assessed during a prenatal healthcare visit for evidence of varicella immunity. Upon completion or termination of pregnancy, women who do not have evidence of varicella immunity should receive the first dose of varicella vaccine before discharge from the healthcare facility. The second dose should be administered at least 4 weeks later at the postpartum or other healthcare visit.
Standing orders are recommended for healthcare settings where completion or termination of pregnancy occurs to ensure administration of varicella vaccine. The manufacturer, in collaboration with CDC, has established a Varicella Vaccination in Pregnancy registry to monitor the maternal—fetal outcomes of pregnant women inadvertently given varicella vaccine.
The telephone number for the Registry is Vaccination of persons with moderate or severe acute illnesses should be postponed until the condition has improved. This precaution is intended to prevent complicating the management of an ill patient with a potential vaccine adverse event, such as fever. Minor illness, such as otitis media and upper respiratory infections, concurrent antibiotic therapy, and exposure or recovery from other illnesses are not contraindications to varicella vaccine.
Although there is no evidence that either varicella or varicella vaccine exacerbates tuberculosis, vaccination is not recommended for persons known to have untreated active tuberculosis. Tuberculosis skin testing is not a prerequisite for varicella vaccination. The effect of the administration of antibody-containing blood products e. Because of the potential inhibition of the response to varicella vaccination by passively transferred antibodies, varicella or MMRV vaccine should not be administered for 3—11 months after receipt of antibody containing blood products.
ACIP recommends applying the same intervals used to separate antibody-containing products and MMR to varicella vaccine see chapter 2, General Recommendations on Immunization and Appendix A pdf icon [3. Immune globulin should not be given for 3 weeks following vaccination unless the benefits exceed those of the vaccine. In such cases, the vaccinees should either be revaccinated or tested for immunity at least 3 months later depending on the antibody-containing product administered and revaccinated if seronegative.
A personal or family i. Studies suggest that children who have a personal or family history of febrile seizures or family history of epilepsy are at increased risk for febrile seizures compared with children without such histories. Children with a personal or family history of seizures of any etiology generally should be vaccinated with MMR vaccine and varicella vaccine because the risks for using MMRV vaccine in this group of children generally outweigh the benefits. No adverse events following varicella vaccination related to the use of salicylates e.
However, the manufacturer recommends that vaccine recipients avoid the use of salicylates for 6 weeks after receiving varicella or MMRV vaccine because of the association between aspirin use and Reye syndrome following chickenpox. As with all vaccines, a severe allergic reaction to a vaccine component or following a prior dose is a contraindication to zoster vaccination. As with other live virus vaccines, pregnancy or planned pregnancy within 4 weeks and immunosuppression are contraindications to zoster vaccination.
Zoster vaccine should not be administered to persons with primary or acquired immunodeficiency. This includes persons with leukemia, lymphomas, or other malignant neoplasms affecting the bone marrow or lymphatic system. The package insert implies that zoster vaccine should not be administered to anyone who has ever had leukemia or lymphoma. However, ACIP recommends that persons whose leukemia or lymphoma is in remission and who have not received chemotherapy or radiation for at least 3 months can be vaccinated.

Persons receiving high-dose corticosteroid therapy should not be vaccinated. High dose is defined as 20 milligrams or more per day of prednisone or equivalent lasting two or more weeks. Zoster vaccination should be deferred for at least 1 month after discontinuation of therapy.
As with other live viral vaccines, persons receiving lower doses of corticosteroids may be vaccinated. Topical, inhaled or intraarticular steroids, or long-term alternate-day treatment with low to moderate doses of short-acting systemic corticosteroids are not considered to be sufficiently immunosuppressive to contraindicate zoster vaccine. Low doses of drugs used for the treatment of rheumatoid arthritis, inflammatory bowel disease, and other conditions, such as methotrexate, azathioprine, or 6-mercaptopurine, are also not considered sufficiently immunosuppressive to create safety concerns for zoster vaccine.
Low-dose therapy with these drugs is NOT a contraindication for administration of zoster vaccine. The experience of hematopoietic stem cell transplant recipients with varicella-containing vaccines, including zoster vaccine is limited. Physicians should assess the immune status of the recipient on a case-by-case basis to determine the relevant risks.
If a decision is made to vaccinate with zoster vaccine, the vaccine should be administered at least 24 months after transplantation. The safety and efficacy of zoster vaccine administered concurrently with recombinant human immune mediators and immune modulators such as the anti—tumor necrosis factor agents adalimumab, infliximab, and etanercept is not known. It is preferable to administer zoster vaccine before treatment with these drugs.
If it is not possible to administer zoster vaccine to patients before initiation of treatment, physicians should assess the immune status of the recipient on a case-by-case basis to determine the relevant risks and benefits. Otherwise, vaccination with zoster vaccine should be deferred for at least 1 month after discontinuation of treatment.
As with all vaccines, moderate or severe acute illness is a precaution to vaccination. Current treatment with an antiviral drug active against herpesviruses, such as acyclovir, famciclovir, or valacyclovir, is a precaution to vaccination. These drugs can interfere with replication of the vaccine virus.
Persons taking these drugs should discontinue them at least 24 hours before administration of zoster vaccine, and the drugs should not be taken for at least 14 days after vaccination. Persons with a history of varicella are immune and generally maintain a high level of antibody to varicella zoster virus, a level comparable to that found in donated blood and antibody-containing blood products. As a result, unlike most other live virus vaccines, recent receipt of a blood product is not a precaution for zoster vaccine.
Zoster vaccine can be administered at any time before, concurrent with, or after receiving blood or other antibody-containing blood products. The most common adverse reactions following varicella vaccine are local reactions, such as pain, soreness, erythema, and swelling. These local adverse reactions are generally mild and self-limited. In both circumstances, a median of two lesions have been present. These lesions generally occur within 2 weeks, and are most commonly maculopapular rather than vesicular. Most of these generalized rashes occur within 3 weeks and most are maculopapular.
Systemic reactions are not common. The majority of these episodes of fever have been attributed to concurrent illness rather than to the vaccine. Varicella vaccine is a live virus vaccine and may result in a latent infection, similar to that caused by wild varicella virus. Consequently, zoster caused by the vaccine virus has been reported, mostly among vaccinated children.
Not all these cases have been confirmed as having been caused by vaccine virus. The risk of zoster following vaccination appears to be less than that following infection with wildtype virus. The majority of cases of zoster following vaccine have been mild and have not been associated with complications such as postherpetic neuralgia.
Measles-like rash was observed in 3. Two postlicensure studies indicated that among children 12 through 23 months of age, one additional febrile seizure occurred 5—12 days after vaccination per 2,—2, children who had received the first dose of MMRV vaccine, compared with children who had received the first dose of MMR vaccine and varicella vaccine administered as separate injections at the same visit.

Data from postlicensure studies do not suggest that children 4—6 years of age who received the second dose of MMRV vaccine had an increased risk for febrile seizures after vaccination compared with children the same age who received MMR vaccine and varicella vaccine administered as separate injections at the same visit.
No serious adverse reactions were identified during the trial. Available data suggest that transmission of varicella vaccine virus is a rare event. Instances of suspected secondary transmission of vaccine virus have been reported, but in few instances has the secondary clinical illness been shown to be caused by vaccine virus. Several cases of suspected secondary transmission have been determined to have been caused by wild varicella virus. In studies of household contacts, several instances of asymptomatic seroconversion have been observed.
It appears that transmission occurs mainly when the vaccinee develops a rash. If a vaccinated person develops a rash, it is recommended that close contact with persons who do not have evidence of varicella immunity and who are at high risk of complications of varicella, such as immunocompromised persons, be avoided until the rash has resolved. Transmission of varicella due to vaccine virus from recipients of zoster vaccine has not been reported.
