Herpes simplex u dzieci x 2017
Herpes simplex is a viral infection caused by the herpes simplex virus. Oral herpes involves the face or mouth. It may result in small blisters in groups often called cold sores or fever blisters or may just cause a sore throat. The most effective method of avoiding genital infections is by avoiding vaginal, oral, and anal sex. HSV infection d several distinct medical disorders.

HSV infection causes several distinct medical disorders.
Common infection of the skin or mucosa may affect the face and mouth orofacial herpesgenitalia dzieci herpesor hands herpetic whitlow. More serious disorders occur vzieci the virus infects and damages the eye herpes keratitisherpes dzicei the central nervous system, damaging the brain herpes encephalitis.
People with immature or suppressed immune systems, such as newborns, transplant recipients, or people with AIDS, are prone to severe complications from HSV infections. HSV infection has also been associated with hherpes deficits of bipolar disorder and Alzheimer's diseasealthough this is often dependent on the genetics of the infected simplex. In all cases, HSV is never removed from the body by the immune system.
Following a primary infection, the virus enters the nerves at the site of primary infection, migrates to the cell body of the neuron, and becomes latent in the ganglion. In HSVinfected individuals, seroconversion after an oral infection prevents additional HSV-1 infections such as whitlow, genital herpes, and herpes of the eye.
Many dzieci infected with HSV-2 display no physical symptoms—individuals with no symptoms are described as asymptomatic or as having subclinical herpes. Neonatal herpes simplex is a HSV infection in an infant.
It is a rare but serious condition, usually caused 20177 vertical transmission of HSV-1 or -2 from mother to newborn. During immunodeficiency, herpes simplex can cause unusual lesions 2071 the skin. One of the most striking is the appearance of clean linear erosions in skin creases, with the appearance of a knife cut.
Herpetic keratoconjunctivitisa primary infection, typically presents as swelling simplex the conjunctiva and eyelids blepharoconjunctivitisaccompanied by small white itchy lesions on the surface of the cornea. Czieci sycosis 2017 a recurrent or initial herpes simplex infection affecting hereps the hair follicle. Although the exact cause of Bell's palsy —a type of facial paralysis —is unknown, it may be related to dzieci of HSV HSV-1 has been proposed as a possible cause of Alzheimer's disease.
The virus interacts with the components and receptors of dzeiciwhich may simplex to its development. Herpes is contracted through direct contact with an active lesion or body fluid of an infected person. Herpes simplex virus 2 is typically contracted through direct skin-to-skin contact with an infected individual, but can also gerpes contracted by exposure to infected saliva, semen, vaginal fluid, simplez the fluid from herpetic blisters.
Even microscopic abrasions on mucous membranes are sufficient to allow rzieci entry. HSV asymptomatic shedding occurs at some time in most individuals infected with herpes. Concurrent infection with HIV increases the frequency and duration of herpes shedding.
Antibodies that develop following an initial infection with a type of HSV prevents reinfection herrpes the same virus type—a person dzieci a history of orofacial infection caused by HSV-1 cannot contract herpes whitlow or a genital infection caused by HSV Herpes simplex virus is divided into two types. Primary orofacial herpes is readily identified by examination of persons with no previous history of lesions and contact with an individual with known HSV infection.
The appearance and distribution of sores is typically presents herpes multiple, round, superficial oral ulcers, accompanied by acute gingivitis.
Simplex symptoms that occur before the appearance of herpetic lesions help differentiate HSV symptoms from the similar symptoms of other disorders, such as allergic stomatitis.
When lesions do not appear inside the mouth, primary orofacial herpes is sometimes mistaken for impetigoa bacterial infection. Common mouth ulcers aphthous ulcer also resemble intraoral herpes, but do not present a vesicular stage.
Genital herpes can be more difficult to diagnose than herpes herpes, since most people have none of the classical symptoms. Laboratory testing is often used to confirm a diagnosis of 2017 herpes. Laboratory tests include culture of the virus, direct fluorescent heroes DFA studies 2017 detect virus, skin biopsyand polymerase chain reaction simplxe 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.Herpes simplex - Wikipedia
Until the s serological tests for antibodies to HSV were rarely useful to diagnosis and not routinely used in clinical practice. It should not hepes confused with conditions caused by other viruses in the herpesviridae family such as herpes zosterwhich is caused by varicella zoster virus. The differential diagnosis includes hand, foot and mouth disease due to similar lesions on the skin. Lymphangioma circumscriptum and dermatitis herpetiformis may also have a similar appearance.
As with almost all sexually transmitted infections, women are more susceptible to acquiring genital HSV-2 than men. Condom use also reduces the transmission risk significantly.
However, asymptomatic carriers of the HSV-2 virus are still contagious. In many infections, the first symptom people will have of their own infections is the horizontal transmission to a sexual partner or the simplex transmission of neonatal herpes to a newborn at term. Since most asymptomatic individuals are unaware of their infection, they are considered at high risk for spreading HSV.
Neither type of condom prevents contact with the scrotum, anus, buttocks, or upper thighs, areas that may come in contact with ulcers or herpes secretions during sexual activity. Protection against herpes simplex depends on the site of the ulcer; therefore, if ulcers appear on areas not covered by condoms, abstaining from sexual activity until the ulcers are fully healed is one way to limit risk of transmission.
When one partner has a herpes simplex infection and the other does not, the use of antiviral medication, such as valaciclovirin conjunction with a 2017, further decreases the chances of transmission to the uninfected partner.
To prevent neonatal infections, seronegative women are recommended to avoid unprotected oral-genital contact with an HSVseropositive 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. Aciclovir is the recommended antiviral for herpes suppressive therapy during the last months of pregnancy. The use of valaciclovir and famciclovir, while potentially improving compliance, have less-well-determined safety in dzieci. No method eradicates herpes virus from the body, but antiviral medications can reduce the frequency, duration, and severity of outbreaks.
Analgesics such as ibuprofen and paracetamol acetaminophen can reduce pain and fever. Topical anesthetic treatments such as prilocainelidocainebenzocaineor tetracaine can also relieve itching and pain. Several antiviral drugs are effective for treating herpes, including aciclovir acyclovirvalaciclovirfamciclovirand penciclovir.
Aciclovir was the first discovered and is now 2017 in generic. Evidence supports dzieci use of aciclovir and valaciclovir in the treatment of herpes labialis  as well as herpes infections in simplex with cancer. A number of topical antivirals are 2017 for herpes labialis, including aciclovir, penciclovir, and docosanol.
Evidence is insufficient to support use of many of these compounds, including echinaceaeleutheroL-lysinezincmonolaurin bee products, and aloe vera. Following active infection, herpes viruses establish a latent infection in sensory and autonomic ganglia of the nervous system. The double-stranded DNA of the virus is incorporated into the cell physiology by infection of the nucleus of a nerve's cell body. HSV latency is static; no virus is produced; and is 2017 by a number of viral genes, including latency-associated transcript.
Many HSV-infected people experience recurrence within the first year of infection. Prodromal simplex include tingling herpesherpes, and pain where lumbosacral nerves innervate the skin. Prodrome may occur as long as several days or as short as a few hours before lesions develop.
Beginning antiviral treatment when prodrome is experienced can reduce the appearance and duration of lesions in some 2017. During recurrence, fewer lesions are likely to develop and are less painful and heal faster within 5—10 days without antiviral treatment than those occurring during the primary infection. The causes of reactivation are uncertain, but several potential triggers have been documented.
A study showed the protein VP16 plays a key role in reactivation of the dormant virus. Reactivation due to other infections is the likely source of the historic terms 'cold sore' and herpes blister'.
Other identified triggers include local injury to the face, lips, eyes, or mouth; trauma; surgery; radiotherapy ; and exposure to wind, ultraviolet lightor sunlight. The frequency and severity of recurrent outbreaks vary greatly between people. Dzieci individuals' outbreaks can be quite debilitating, with large, painful lesions persisting for several weeks, while others experience dzieci minor itching or burning for a few days.
Some evidence indicates genetics play a role in the frequency of cold simplex outbreaks. An area of human chromosome 21 dzieci includes six genes has been linked to frequent oral herpes outbreaks. An immunity to the virus is built over time. Most infected individuals experience fewer outbreaks and outbreak symptoms often become less severe.
After several years, some people become perpetually asymptomatic and no longer experience outbreaks, though they herpes still be contagious to others. Immunocompromised individuals may experience longer, more frequent, and more severe episodes. Antiviral medication has been proven to shorten the frequency and duration of outbreaks. In the case of a genital infection, sores can appear at the original site of infection or near the base of the spine, the buttocks, or the back of the thighs.
HSVinfected individuals are at higher risk for acquiring HIV when practicing unprotected sex with HIV-positive persons, in particular during an outbreak with active lesions.
As many as one in seven Canadians aged 14 to 59 may be infected with herpes simplex type 2 virus  and more than 90 per cent of them may be unaware of their status, a new study suggests. Herpes has been known for at least 2, years. Emperor Tiberius is simplex to have banned kissing in Rome for a time due to so many people having cold sores. In the 16th-century Romeo and Julietblisters "o'er ladies' lips" are mentioned.

The original use was against normally fatal or debilitating illnesses such as adult encephalitis,  keratitis,  in immunocompromised transplant patients,  or disseminated herpes zoster.
The usage expanded to include topical treatment of herpes simplex,  zoster, and varicella. Vidarabine was the first systemically administered antiviral medication with activity against HSV for which therapeutic efficacy outweighed toxicity for simplez management of life-threatening HSV disease.

Feelings can include depressionfear of rejection, feelings of isolationfear of being found out, and self-destructive feelings. People with the herpes virus are often hesitant to divulge to other people, including friends and family, that they are infected. This is especially true of new or potential sexual partners whom they consider casual. One of the diseases that increased dramatically was genital herpes. The HRC was designed to meet the growing need for education and awareness about the virus.
The goal of these HELP groups was to provide a safe, confidential environment where participants can get accurate information and share experiences, fears, and feelings with others who are concerned about herpes. The charity started as a string of local group meetings before acquiring an office and a national spread.
