Herpes simplexhttps://sw.wikipedia.org/wiki/Tutuko
Herpes simplex ni maambukizi ya virusi (herpes virus). Maambukizi yanategemea sehemu ya mwili iliyoambukizwa. Herpes ya mdomo ni ugonjwa wa kawaida unaoshawishi uso au mdomo. Inaweza kusababisha malengelenge madogo katika vikundi, mara nyingi huitwa vidonda vya baridi au malengelenge ya homa. Malengelenge katika sehemu za siri, mara nyingi hujulikana kama herpes, inaweza kuwa na dalili kidogo au kuunda malengelenge yanayopasuka na kusababisha vidonda vidogo. Hizi kawaida huponya kwa wiki mbili hadi nne. Maumivu yanaweza kutokea kabla ya kuonekana kwa malengelenge. Kipindi cha kwanza mara nyingi huwa kali zaidi na kinaweza kuhusishwa na homa, maumivu ya misuli, nodi za limfu zilizovimba, na maumivu ya kichwa. Matatizo mengine yanayosababishwa na virusi vya herpes ni pamoja na: herpetic whitlow, herpes ya jicho, na herpes ya watoto wachanga inapoathiri mtoto mchanga.

Kuna aina mbili za virusi vya herpes simplex, aina ya 1 (HSV-1) na aina ya 2 (HSV-2). HSV-1 mara nyingi husababisha maambukizo karibu na mdomo, wakati HSV-2 husababisha maambukizo katika sehemu ya siri. Wanaambukizwa kwa kuwasiliana moja kwa moja na mtu aliyeambukizwa. Malengelenge katika sehemu za siri huainishwa kama maambukizo ya ngono. Inaweza kuenea kwa mtoto mchanga wakati wa uchapishaji. Baada ya kuambukizwa, virusi husafirishwa pamoja na mishipa ya hisia hadi kwenye seli za neva, ambako hukaa maisha yote. Sababu za kurudia zinaweza kujumuisha: kupungua kwa kazi ya kinga, dhiki, na mwanga wa jua.

Katika hali nyingi, dawa za antiviral huchukuliwa tu wakati dalili ni kali. Dawa ya antiviral ya kila siku inaweza kuagizwa kwa mtu anaye na maambukizo ya mara kwa mara. Hakuna chanjo inayopatikana, na chanjo ya shingles haizuii herpes simplex. Matibabu kwa kutumia dawa za kuzuia virusi kama vile aciclovir au valaciclovir inaweza kupunguza ukali wa dalili.

Viwango vya ulimwenguni pote vya HSV-1 au HSV-2 ni kati ya 60 % na 95 % kwa watu wazima. HSV-1 kawaida huambukizwa wakati wa utoto. Inakadiriwa kuwa watu milioni 536 duniani kote (16 % ya idadi ya watu) waliambukizwa HSV-2 kufikia mwaka 2003, na viwango vilikuwa juu zaidi kwa wanawake na katika nchi zinazoendelea. Watu wengi walio na HSV-2 hawatambui kuwa wameambukizwa.

○ Matibabu - Dawa za OTC
Epuka mguso wowote wa kimwili, kama vile kumbusu mtoto, wakati malengelenge yapo, kwani kugusa kunaweza kusambaza maambukizi kwa watu wengine. Unapaswa kupumzika bila kunywa pombe.

  • Herpes simplex ya mdomo.
  • Herpes simplex – Maambukizi ya Herpes simplex kwenye vidole ni ya kawaida zaidi kwa watoto wadogo kuliko kwa watu wazima.
  • Ikiwa dalili ni kali, kuchukua dawa za kuzuia virusi husaidia sana kupunguza dalili.
  • Ikitokea mdomoni, angular cheilitis inapaswa kutofautishwa. Hata hivyo, katika picha hii, kuna uwezekano mkubwa wa herpes, kwani kuna malengelenge madogo madogo karibu na kinywa.
  • Herpes gingiva ― Maambukizi ya ngiri yanaweza kutokea si tu mdomoni, bali pia katika sehemu za ndani ya mdomo, perinasal, na periocular.
  • Herpes genitalis kwa wanawake.
  • Herpes kwenye matako ni dalili ya kurudi tena wakati wa uchovu.
  • Katika visa vya maambukizi yaliyoenea, matibabu ya kina yanaweza kuhitajika, kama vile tutuko wote.

Maambukizi ya HSV-1 huanza kwa kuingia kwenye seli za epithelium, ikafuata na ukimya, hasa katika neva, kisha kuanzisha tena. HSV-1 kwa kawaida husababisha milipuko ya awali na ya mara kwa mara ya vesikulari, hasa kwenye mdomo na utando wa uzazi. Udhihirisho wake huanzia ugonjwa wa malengelenge ya orolabial hadi hali mbalimbali kama vile herpetic folliculitis, maambukizo ya ngozi, ushtuko wa macho, na kesi kali kama vile herpes encephalitis. Matibabu ya antiviral husaidia kudhibiti maambukizi ya HSV.
Herpes simplex virus type 1 (HSV-1) is a member of the Alphaherpesviridae subfamily. Its structure is composed of linear dsDNA, an icosahedral capsid that is 100 to 110 nm in diameter, with a spikey envelope. In general, the pathogenesis of HSV-1 infection follows a cycle of primary infection of epithelial cells, latency primarily in neurons, and reactivation. HSV-1 is responsible for establishing primary and recurrent vesicular eruptions, primarily in the orolabial and genital mucosa. HSV-1 infection has a wide variety of presentations, including orolabial herpes, herpetic sycosis (HSV folliculitis), herpes gladiatorum, herpetic whitlow, ocular HSV infection, herpes encephalitis, Kaposi varicelliform eruption (eczema herpeticum), and severe or chronic HSV infection. Antiviral therapy limits the course of HSV infection.

Herpes simplex virus type 2 (HSV-2) ni maambukizi yaliyoenea, yanayoathiri karibu 22 % ya watu wazima wenye umri wa miaka 12 na zaidi, jumla ya watu wazima milioni 45 nchini Marekani. Ingawa HSV-1 husababisha vidonda vya mdomo, inaweza pia kusababisha vidonda katika sehemu za siri. Hata hivyo, kwa wagonjwa wenye vidonda katika sehemu za siri, HSV-2 ni chanzo kikuu cha wasiwasi. Dalili za milipuko wa HSV-2 mara nyingi hazionekani, kama vile kuwasha sehemu za siri na muwasho, jambo ambalo linaweza kuchelewesha utambuzi na matibabu. Ucheleweshaji huu unaweza kusababisha maambukizi zaidi kwa watu ambao hawajaambukizwa.
Herpes simplex virus type 2 (HSV-2) continues to be a common infection, affecting approximately 22% of adults ages 12 and older, representing 45 million adults in the United States alone. While HSV-1 often affects the perioral region and can be known to cause genital lesions, HSV-2 is more commonly the consideration when patients present with genital lesions. Despite this, most outbreaks of the infection will present with nonspecific symptoms such as genital itching, irritation, and excoriations, which may cause diagnosis and treatment to be delayed. As a result, further exposure to uninfected individuals may occur.

Herpes simplex virus (HSV) mara nyingi husababisha maambukizo kama vile malengelenge katika sehemu za siri na vidonda vya baridi kwa vijana na watu wazima. Wakati HSV inapomwambukiza mtoto mchanga ndani ya wiki 4–6 za kwanza za maisha, inaweza kusababisha ugonjwa mbaya na matokeo mabaya. Utambuzi wa haraka wa maambukizo ya HSV kwa watoto wachanga ni muhimu ili kuzuia ugonjwa huo kuwa mbaya zaidi, na kuzuia matatizo ya neva (hata kifo).
Herpes simplex virus (HSV), a member of the Herpesviridae family, is a well-known cause of infections including genital herpes and herpes labialis in the adolescent and adult population. Transmission of HSV infection to an infant during the first 4-6 weeks of life can lead to devastating disease with the potential for poor outcomes. Early diagnosis is imperative when evaluating neonatal HSV infection in order to prevent further disease progression, neurological complications, and even death.

Maambukizi ya Herpes simplex ni ya kawaida sana na yanaweza kuambukizwa kutoka kwa wanawake wajawazito hadi kwa watoto wao. Virusi hawa vinaweza kusababisha matatizo makubwa ya kiafya au hata kifo kwa watoto wachanga. Ingawa ni nadra wakati wa ujauzito wenyewe, mara nyingi hutokea wakati wa kujifungua. Hatari inaongezeka ikiwa mama atapandwa ugonjwa katika hatua za baadaye za ujauzito. Hata hivyo, hatari hii inaweza kupunguzwa kwa kutumia dawa za kuzuia virusi au kwa kuchagua chaguo la C katika hali fulani.
Infection with herpes simplex is one of the most common sexually transmitted infections. Because the infection is common in women of reproductive age it can be contracted and transmitted to the fetus during pregnancy and the newborn. Herpes simplex virus is an important cause of neonatal infection, which can lead to death or long-term disabilities. Rarely in the uterus, it occurs frequently during the transmission delivery. The greatest risk of transmission to the fetus and the newborn occurs in case of an initial maternal infection contracted in the second half of pregnancy. The risk of transmission of maternal-fetal-neonatal herpes simplex can be decreased by performing a treatment with antiviral drugs or resorting to a caesarean section in some specific cases.

Herpes simplex virus (HSV) aina ya 1 na 2 huambukiza watu wengi duniani kote. Kwa kawaida, virusi hukaa kimya katika seli za neva baada ya kuambukiza ngozi, lakini unaweza kuamsha baadaye na kusababisha vidonda vya baridi. Wakati mwingine husababisha matatizo makubwa kama maambukizi ya macho, uvimbe wa ubongo, au hali hatari kwa watoto wachanga na watu wenye kinga dhaifu. Ingawa dawa za sasa husaidia kudhibiti maambukizo, hatari ya upinzani wa dawa na athari mbaya bado ni wasiwasi. Tunahitaji dawa mpya ili kulenga virusi kwa ufanisi.
Infection with herpes simplex virus (HSV) types 1 and 2 is ubiquitous in the human population. Most commonly, virus replication is limited to the epithelia and establishes latency in enervating sensory neurons, reactivating periodically to produce localized recurrent lesions. However, these viruses can also cause severe disease such as recurrent keratitis leading potentially to blindness, as well as encephalitis, and systemic disease in neonates and immunocompromised patients. Although antiviral therapy has allowed continual and substantial improvement in the management of both primary and recurrent infections, resistance to currently available drugs and long-term toxicity pose a current and future threat that should be addressed through the development of new antiviral compounds directed against new targets.
