Herpes, also called herpes simplex, is any of the diseases caused by herpes simplex virus (HSV). There are two subtypes of the virus that can each be responsible for either cold sores or genital herpes; although human herpesvirus 1 (herpes simplex virus-type 1 or HSV-1) is the overwhelmingly common cause of cold sores, and HSV-2 is responsible for a slight majority of genital herpes cases. Herpes simplex virus (HSV) is a member of the Herpesviridae family of viruses, a family of DNA viruses. UI: 14624112) HSV 1 and 2 correspond to HHV 1 and 2, and both are very prevalent in the human population, with as many as 30-70% of all people tested testing positive for antibodies at some point in their lifetime. HSV's genome is a double stranded linear DNA, with about 50% sequence homology between HSV-1 and HSV-2.
Active replication of the virus in these cells results in the lesions of typical vesicles and shedding of the virus. The virus is destroyed, except for virus which, through retrograde axonal transport, is sequestered in the ganglion of sensory neurons. All symptoms of infection disappear at that point and the infected person enters a period of "latent infection". Even during latent infections, when there are no symptoms or signs of illness, the virus is maintained in a repressed state in nerve cells. Herpes Simplex viruses generally cause mucocutaneous infection, that is, cells of the skin and the mucous membranes are infected. The initial infection with the virus is called the primary infection, and can be accompanied by systemic systems such as fever and muscle aches. In general, lesions from HSV 1 are more commonly seen on the face, but also accounts for a large minority of genital infections. Transmission can occur when sores are visible, as well as when there are no visible lesions.
The diagnosis of a herpes simplex infection is ordinarily a clinical one, that is- it is made by a trained health care provider based on the patient's history and physical findings, rather than on laboratory tests. Viral culture is an expensive laboratory test that must be carried out for 10 days in order to assume negative results.
These cell culture dishes are pictured from a laboratory performing culture of herpes simplex virus.
Diagnostic tests on the immune response to the virus can determine not only the subtype of herpes simplex infection but whether the outbreak is primary or recurrent. HSV-1 and HSV-2 each have respective variations in virally produced glycoprotein G, and immunoglobulin G (IgG) produced by an infected person differs accordingly. Cold sores are most commonly caused by Human herpesvirus 1 and are ubiquitous in distribution in human populations.
In population studies in the United States, both serotypes of the herpes virus are prevalent in symptomatic genital herpes infections. Although both types of herpes simplex virus can account for genital herpes, and cause a very similar appearing rash, "HSV-1 has a much lower recurrence rate. The Center for Disease Control (CDC) in the United States recommends that genital lesions be cultured in order to determine the type of HSV infection, since the severity and clinical course of the disease can be better predicted with this information.
There is a relationship between genital herpes and the risk of catching (and spreading) additional venereal diseases, since the ulcers caused by herpes are more vulnerable to invasion by pathogens than intact skin or mucosa.
Although herpes infection is aggravating in healthy adults, it is a lethal disease in very young babies. However, newborns have a limited immune system for the first 3 weeks of life, and even a kiss by a well-meaning friend or relative who bears a virus-shedding cold sore on the lips can cause infection in the newborn (albeit rarely). All the immunosuppressive drugs used to allow transplant patients to keep their transplanted organs healthy have an unfortunate side effect of reactivating latent herpes simplex infections.
Herpes has been recognized for centuries, "cold sores" (herpes febrilis) were described by the Roman physician Herodotus in the year 100 CE.
Caused by the protozoan called toxoplasma gondii, Toxoplasma is very common parasite found in humans. When a pregnant woman gets infected with toxoplasma, there is a chance that the infection can be passed to the fetus via the chorionic villi in the placenta. Even with the infection, a good majority (67% of infected fetuses) are born with no symptoms. If the mother is confirmed to be infected with toxoplasma, then treat the mom with spiramycin.
Avoid handling cat litter, particularly cats who have access to the outdoors where they may eat infected rodents and small birds.
Wear gloves if you are going to be working in the garden or will be handling soil which may potentially have toxoplasma. Rubella is spread through respiratory droplets, and the mother who gets it will show upper respiratory tract symptoms, rash that starts on the trunk, lymphadenopathy, and arthritis. The baby is often born with intrauterine growth restriction (IUGR), meaning they are restricted from growth in the placenta.
Unfortunately there is currently no antiviral treatment available for congenital rubella, and the only thing you can do is give the baby supportive therapy.
Rubella, however, is an easy disease to prevent, and anyone who has not been vaccinated with MMR should consider it before getting pregnant. CMV is transmitted via bodily fluids, which includes sexual contact, organ transplants, blood transfusions, breast milk, saliva, urine, and transplacentally from mother to fetus. Congenital CMV infects up to 40,000 newborns annually in the US but the majority are asymptomatic.
For those who are born with symptoms, you may see intrauterine growth restriction (leading to mental retardation and microcephaly), jaundice, seizures, periventricular calcifications (in brain on CT), hearing loss, petechial rash, pneummonia, hepatosplenomegaly, or psychomotor retardation.
You can diagnose the doing CMV titers (part of TORCH screen) on the newborn baby and confirm with viral cultures from urine or saliva samble from the baby. To prevent congenital CMV, the pregnant mother should wash hands thoroughly after touching diapers or saliva, and avoid any contact with bodily fluids, particularly from young children who are at more risk of getting CMV. Herpes simplex virus (HSV) comes in two strains, HSV 1 (oral herpes), and HSV 2 (genital herpes).
HSV is transmitted via skin or mucous membrane contacts, such as during birth through an infected genital tract.
To diagnose on a neonate, you can take a swab sample from the conjunctivae or oropharynx of the neonate and do a viral culture to detect the virus. Neonates who have a confirmed diagnosis of HSV should be treated with a full course of intravenous acyclovir. If you suspect HSV in the mother, or if the mother has a history of HSV, then you should recommend doing a c-section to prevent the fetus from passing through a potentially infected vaginal canal. Unlike other TORCH infections where the infected patient is often asymptomatic, in congenital syphilis, 40% of fetuses get hydrops fetalis and do not make it past birth.
Early symptoms (before 2 yrs): Early on, you will find failure to thrive, anemia, maculopapular rash, hepatosplenomegaly, periostitis, and rhinitis. Late symptoms (after 2 yrs): Later on, the patients may develop Hutchinson teeth (notched teeth), saddle nose (from bridge of nose breaking), saber shin (anteriorly-curved tibia), and short maxilla. If the neonate tested positive for syphilis, treat with parenteral penicillin G for 10 days.
To prevent congenital syphilis, screen the expectant mother for syphilis and treat her with penicillin G to minimize transmission to the fetus.

Herpes infectionGenital herpes is an infection caused by herpes simplex virus type 2, which is transmitted through sexual intercourse. Herpes simplex virus type 2 is transmitted through sexual contact, being highly contagious when the patient has active lesions (the symptoms will be explained below).
The frequency of virus shedding is becoming smaller as the years pass from the first appearance of herpes.


Herpes simplex virus Whenever the patient has a crisis, its transmission rate rises again, going back to last fall as the crisis is getting older.
HIV-positive patients who also have genital herpes are the group with the highest transmission possibility during the asymptomatic phase. The herpes simplex virus type 1 often causes lesions only in the mouth, but can be transmitted to the genitals during oral sex.
The herpes simplex virus type 2 survives for a very little time in the environment, transmission through clothing or towels is uncommon.
The use of condoms reduces the chance of transmission, but does not eliminate it completely, since the herpes lesions can appear in the genital areas that are not covered by the condom. Most patients who become infected with herpes simplex virus type 2 do not develop the disease, remaining asymptomatic and unaware of the infection.
Herpes infection The first time that the lesions of genital herpes occur after the patient has been infected is called the primary infection. The symptoms of genital herpes tend to develop in three to seven days after intercourse responsible for the infection, but in some cases may take up to two weeks. Besides the typical lesions of herpes, primary infection is usually accompanied with other symptoms such as fever, malaise and body ache. The lesions in primary infection of genital herpes usually take on average 20 days to disappear. Herpes recurrencesAfter primary infection genital herpes lesions disappear remaining silent for several months. The recurrent lesions tend to be less painful and last for about 10 days, half the time of primary infection. Days before the lesions recur, the patient may experience some symptoms of warning, like an itchy labia majora, a penile numbness or tingling in the genital region.
In some cases the patient may not develop symptoms of primary infection soon after infection, ulcers can appear only years later, after some event that reduces your immunity. Herpes diagnosis The lesions of genital herpes are typical during the crisis and are easily recognized by experienced physicians.
The tests can identify the virus, but do not provide information on when the patient was infected. Herpes drugsAlthough there is no cure for genital herpes, infection can be controlled with antiviral therapy. Three antiviral drugs are used for the treatment of genital herpes: Acyclovir (Zovirax), Famciclovir (Famvir), Valacyclovir (Valtrex). In patients with more than six outbreaks per year can be indicated suppressive therapy, which consists of continuous daily use of an antiviral at low doses to avoid recurrences.
In addition to the antiviral drugs, certain home therapy can be used to alleviate the symptoms of an outbreak of genital herpes.
The phenomenon of latent infection permits long-term persistence of the virus within the host and potential future transmissibility to others."[1] Other species of Herpes virus are also human pathogens, notably Herpes Zoster, the cause of both chicken pox (in acute infection) and shingles (chronic infection with reactivation). Many of the polypeptides produced by each type of virus are identical, and are coded by the homologous regions of DNA, but some of the expressed proteins are different and some of these distinct proteins are antigenic - that is, they give rise to an antibody response in infected hosts.
During this time, special tests done in research can demonstrate single strand viral RNA in the infected nerves. In addition to the common mucocutaneous infection, HSV 1 and 2 can also cause keratitis (inflammation in the eye), encephalitis (brain infection), and severe neonatal disease if acquired during pregnancy. However, a clinical diagnosis does not distinguish between HSV-1 and HSV-2 infection, except by probability. Because HSV 2 is spread more commonly by sexual contact, it is easier to prevent than HSV 1. They can infect anytime during gestation, and sometimes during the time of delivery as well.
If both the baby and the mom are infected, then treat the mother with pyrimethamine and sulfonamide, which will cross the placenta and treat the fetus as well.
Rubella cases in the ¬†US mainly happen in mothers from countries who did not have an MMR vaccination program. Like all other TORCH infections, the mother may also be asymptomatic yet still have the risk of transmitting the infection to fetuses. It is often symmetric, meaning both the head and the body are restricted from growing, and this causes the baby to be born with a small head (microcephaly), and therefore mental retardation. For those women who do get the vaccine, they should wait at least 28 days before attempting to get pregnant, since MMR is a live vaccine and your body needs time to build up those antibodies against it. In fact, up to 60% of adults in the US have tested seropositive for it, and like toxoplasma, most people’s immune systems are strong enough to make them asymptomatic. Usually it can transmit from the mother to fetus when the mother has either a primary infection or reactivation of the CMV during pregnancy.
Physical and supportive therapy is the only thing you can do at this point, like giving hearing aids, special education, etc.
Women who are confirmed to be infected should get ganciclovir treatment to decrease the risk of spread to the fetus. HSV 1 can also be found in genital herpes and vice versa, but in terms of congenital HSV, HSV 2 is the more common one you’ll see. Like many TORCH infections, mother who have genital herpes often may not show signs of an outbreak, but still have the risk of transmitting it to the fetus during vaginal birth.
Neonates with this presentation have the best survival and usually have no mental retardation or developmental delays. You see meningoencephalitis, seizures, bulging anterior fontanel, poor feeding, and irritability. You could also do dark field microscopy to detect the bacterium, which is a more accurate test, especially in primary syphilis. If the neonate tested negative but the mother is postive for untreated syphilis, then treat the baby with a dose of IM benzathine penicillin. Close-up of blisters on the glans of the penis in a 25 year old male patient infected with the Herpes simplex virus (genital herpes). Individuals who have genital herpes are encouraged to talk to a sexual partner, use condoms and take other measures to prevent transmission. The herpes simplex virus type 1 can cause genital herpes as well, but is usually associated with herpes labialis.
A big problem is that genital herpes transmission can occur even in times when the patient is asymptomatic. The disposal out of the crisis is greatest in the first three months after primary infection. 70% of transmissions of genital herpes occur in the asymptomatic phase, since during the crises the patient usually avoids having sex. Once infected, patients with type 1 herpes can transmit the disease in the same way that patients infected with the second type.
For example, a herpes lesion on the scrotum remains exposed even with the proper use of condoms.
They can arise in lymph nodes groin area, and if the ulcers are close to the urethra, there may be intense pain while urinating. In women lesions may be visible outside the vagina, but they usually occur inside, where they are hidden.
In most patients the infection emerges from time to time, in some cases, more than once a year. Among the most common are extreme physical exertion, emotional stress, illness, recent surgery, excessive sun exposure and immunosuppression. In these cases, in spite of the first appearance of the wounds, the disease behaves more like a recurrence than as primary infection, being shorter and less painful. If there is need for laboratory confirmation, or if the damage is not very typical, the doctor may take samples of ulcers for virus identification.
The antiviral treatment serves to accelerate the healing of injuries, alleviate the symptoms to prevent complications and reduce the risk of transmission to others. People with a history of recurrent genital herpes are often advised to keep a stock of antiviral medication at home, in order to start treatment as soon as the first signs of a recurrence.


The advantage of suppressive therapy is that it reduces the frequency and duration of relapse, and can also reduce the risk of transmission of herpes virus to the uninfected partner. Some experts recommend pause treatment periodically (every few years) to determine if the suppressive therapy is still required.
Serological testing for such antibodies is the usual means to determine the type of HSV (1 or 2) infection present in patients. Although genital lesions are a form of STD, other lesions can be contracted without sexual contact.
Confirming a diagnosis and clarifying the actual virus type involve requires laboratory testing. If the individual has clear signs of a genital herpes infection, but the tests for IGG are negative, the most likely explanation is that this is a primary outbreak, and the patient has not yet begun production of that type of antibody.
More than 50 million people are infected in that country, making this the most common STD in the USA. Since they can cause mental retardation, morbidity, and even death, they are important to recognize and prevent.
But because pyrimethamine and sulfonamide have the adverse effect of bone marrow suppression, you would also want to treat with leukovorin. The mother may have heterophile negative mononucleosis, presenting with fever, sore throat, and fatigue. Therefore, even when the virus is eliminated intermittently, the patient can transmit genital herpes to your partner(s).
After 10 years of infection, the transmission out of the crisis is becoming increasingly less common. The difference is that crises are usually milder and less frequent, and the transmission out of the crisis is less common. In patients who develop symptoms, the clinical picture is divided into two situations: primary infection and recurrence.
90% of patients experience a recurrence in the first interval of 18 months after primary infection.
In asymptomatic phases it is possible to investigate the herpes infection through serology, which can identify both the herpes simplex virus type 1 and type 2. Women who are having pain urinating may feel less discomfort during the sitz bath or a shower with warm water. Regardless of how they were contracted, however, an infected person can spread virus to another person with mucosa to mucosa or skin to mucosa contact. The most definitive proof of infection, the "gold standard" of diagnostic tests, is the growth of the virus in artificial culture from a specimen taken from the patient's lesions.
Confirmation of that presumed diagnosis of a primary herpes infection can be made on follow-up testing, with demonstration of anti-HSV IgG levels. So far in my pediatric rotation, I have seen a case of it, and so it is something we will see more as doctors.
When other animals outside get contaminated with these feces, then they too catch the infection. Also because there is risk for retinitis, you’d also want to give to refer the baby for an ophthalmic examination for risk for retinitis. Like other TORCH infections, mothers who do not show signs of the infection can still be at risk of passing the infection to their fetuses. Usually in a period of 100 days, the patient has 2 or 3 times of eliminating the virus asymptomatically.
400 patients with genital herpes were studied for more than 10 years and sampled out of the genitals of seizures for a period of 30 days. The lesions of genital herpes can also arise at any point of the perineum and around the anus of the patient who practice anal sex.
However, there are cases in which recurrence is not possible to identify any triggering factor.
The problem is that, as the first appearance of the wound, the patient tends to think he has been infected recently, and this often causes problems in couples with a stable relationship for years.
Although primary ulcers have a high rate of viral shed, recurrent lesions shed virus at a much lower rate, and so culture of recurrent lesions has a high false negative rate. You usually only find symptoms of the infection when people become immunocompromised, like in HIV patients. Toxoplasma spreads through the blood and eventually encysts in tissue cells permanently (but contained by our immune systems). Patients usually having frequent recurrences are those who have a prolonged primary infection with herpes initial lesions lasting more than one month. In these situations it is very difficult to establish precisely when the patient was infected and whoor what was the cause. UI: 9674772), and reactivation of the virus from sacral nerves is the basis for recurrent genital herpes. Accordingly, in patients with typical presentations of recurrent outbreaks, failure to culture the virus in no way overturns the diagnosis.
While humans can get it through handling cat litter, the major cause of transmission in the US and Europe is actually through eating meat containing the cysts, particularly pork, venison, and lamb. Type 1 virus is the usual cause of cold sores around the mouth, and herpes simplex infection in the eye.
It is commonly passed on by close contact such as kisses from a family member who has a cold sore.) In many people the primary infection does not cause any symptoms, although in some cases symptoms do occur. A minor and temporary inflammation of the conjunctiva (conjunctivitis) or eyelids (blepharitis) may occur with active infection, often at the same time as the cornea is infected. Often people who get active eye infection will have had previous cold sores during their lifetime. They may also put some stain on the front of your eye to show up any irregular areas on the cornea. If your doctor suspects a herpes eye infection you will usually be referred urgently to an eye specialist. This is to confirm the diagnosis and to determine whether the infection is in the top layer of the cornea (epithelial keratitis), or if the deeper layers are involved (stromal keratitis).
These do not kill the virus but stop it from multiplying further until the infection clears.
You are likely to be kept under review, until the infection clears, to check that the cornea does not become infected. Note: if you have herpes simplex eye infection, you should stop wearing any contact lens until 24 hours after your symptoms and the infection have completely gone away. As mentioned above, these occur if the virus reactivates from time to time - similar to cold sores. A recurrent infection may occur any time between a few weeks and many years after the first active infection.
At least half of people who have one episode of active infection will have a recurrence within 10 years of the first.
If recurrences are frequent or severe, then your eye specialist may advise that you take antiviral tablets each day to prevent episodes of active infection. Studies have shown that, on average, the number of recurrences is roughly halved in people who take regular antiviral tablets. Some people say that episodes of active herpes infection may be triggered by strong sunlight. It is also possible that active infection may be triggered if you are run down or unwell for another reason. Some women find that they get recurrences around the time of their period but again there is limited evidence to support this.
However, severe and recurrent herpes simplex eye infections may lead to serious scarring, impaired vision and even blindness in some cases.
