Borelioza mózgu przenoszona przez kleszcze
Charakterystyka, pielęgnacja i opieka

Borelioza mózgu przenoszona przez kleszcze (TBE) to wirusowa infekcja OUN o dwufazowym przebiegu, z pierwszą fazą grypopodobną pojawiającą się 7-14 dni po ukąszeniu, a drugą fazą obejmującą zapalenie opon mózgowo-rdzeniowych (37,3%), zapalenie mózgu (49,2%), zapalenie rdzenia kręgowego (2,7%) lub ich kombinacje (10,5%). Objawy neurologiczne mogą obejmować sztywność karku, niedowłady (10,1%), porażenia nerwów czaszkowych (4,5%), ataksję, drgawki i zaburzenia świadomości. Diagnostyka opiera się na wykryciu przeciwciał IgM w płynie mózgowo-rdzeniowym i/lub surowicy metodą ELISA, pojawiających się od 6 dnia objawów i utrzymujących do 10 miesięcy. Leczenie jest objawowe i wspierające, obejmujące hospitalizację, kontrolę ciśnienia śródczaszkowego, leczenie przeciwdrgawkowe, nawadnianie oraz w ciężkich przypadkach mannitol i glikokortykosteroidy (z ograniczonym zastosowaniem deksametazonu). Immunoglobuliny dożylne mogą być rozważane w ciężkich przebiegach. Śmiertelność wynosi 0,5-2% dla podtypu europejskiego, a powikłania neurologiczne utrzymują się u 60% pacjentów, z długotrwałymi objawami takimi jak zmęczenie (17%), osłabienie (13,4%) i zaburzenia poznawcze.

Objawy i diagnostyka boreliozy mózgu przenoszonej przez kleszcze

Borelioza mózgu przenoszona przez kleszcze (tick-borne encephalitis, TBE) jest wirusową chorobą zakaźną centralnego układu nerwowego, która występuje w wielu częściach Europy i Azji. Choroba ta jest przenoszona głównie przez ukąszenia zainfekowanych kleszczy, choć może być również przekazywana przez spożycie niepasteryzowanych produktów mlecznych.12

Przebieg kliniczny TBE jest bardzo zróżnicowany. U wielu pacjentów zakażenie przebiega bezobjawowo lub z łagodnymi objawami przypominającymi grypę.34 Charakterystyczny jest dwufazowy przebieg choroby. Pierwsza faza pojawia się zwykle 7-14 dni po ukąszeniu kleszcza i obejmuje objawy grypopodobne takie jak gorączka, ból głowy, zmęczenie, bóle mięśniowe oraz nudności.56

U około 20-30% zakażonych pacjentów rozwija się druga faza choroby, która obejmuje zajęcie centralnego układu nerwowego. Może przybierać formę:78

  • Zapalenia opon mózgowo-rdzeniowych (meningitis) – 37,3% przypadków
  • Zapalenia mózgu (meningoencephalitis) – 49,2% przypadków
  • Zapalenia rdzenia kręgowego (meningomyelitis) – 2,7% przypadków
  • Zapalenia mózgu i rdzenia kręgowego (meningoencephalomyelitis) – 10,5% przypadków

9

W cięższych przypadkach mogą wystąpić objawy takie jak sztywność karku, nadwrażliwość na światło, niedowłady kończyn, porażenia nerwów czaszkowych, zaburzenia mowy, ataksja, drgawki i zaburzenia świadomości.1011 Około 10,1% pacjentów rozwija niedowłady kończyn, przy czym częściej dotyczy to kończyn górnych. Porażenia nerwów czaszkowych obserwuje się u około 4,5% pacjentów.12

Diagnostyka TBE opiera się na wykryciu specyficznych przeciwciał IgM w płynie mózgowo-rdzeniowym oraz/lub w surowicy, głównie metodą ELISA. Przeciwciała TBE pojawiają się w ciągu 6 dni od wystąpienia objawów i mogą być wykrywane, gdy obecne są objawy neurologiczne. Specyficzne przeciwciała IgM mogą utrzymywać się do 10 miesięcy u osób, które nabyły zakażenie w sposób naturalny.1314

Leczenie i postępowanie w boreliozie mózgu przenoszonej przez kleszcze

W przypadku boreliozy mózgu przenoszonej przez kleszcze nie istnieje specyficzne leczenie przeciwwirusowe. Postępowanie terapeutyczne ma charakter objawowy i wspierający, zależny od nasilenia objawów.1516

Postępowanie w łagodnych przypadkach

W przypadku pacjentów z łagodnymi objawami zaleca się:1718

  • Odpoczynek
  • Nawodnienie
  • Leki przeciwgorączkowe i przeciwbólowe (np. paracetamol, ibuprofen)
  • Leki przeciwwymiotne w przypadku nudności i wymiotów

Postępowanie w ciężkich przypadkach

Pacjenci z zapaleniem opon mózgowo-rdzeniowych, zapaleniem mózgu lub zapaleniem rdzenia kręgowego wymagają hospitalizacji i intensywnej opieki medycznej. Postępowanie obejmuje:1920

  • Kontrolę bólu w przypadku nasilonych objawów oponowych
  • Terapię przeciwwymiotną i nawadnianie w przypadku towarzyszących nudności i wymiotów
  • Utrzymanie równowagi wodno-elektrolitowej
  • Monitorowanie i kontrolę ciśnienia śródczaszkowego
  • Leki przeciwdrgawkowe w przypadku napadów drgawkowych
  • Intubację i wspomaganie oddychania u pacjentów z porażeniem mięśni oddechowych

2122

W przypadku obrzęku mózgu i znacznego wzrostu ciśnienia śródczaszkowego stosuje się mannitol dożylnie i/lub glikokortykosteroidy.23 Choć stosowanie deksametazonu może zmniejszać obrzęk mózgu w ostrym wirusowym zapaleniu mózgu, jego rutynowe stosowanie w TBE nie jest zalecane ze względu na brak potwierdzonej skuteczności i obserwacje wskazujące na przedłużenie hospitalizacji.2425

W niektórych przypadkach ciężkiego TBE rozważa się zastosowanie immunoglobulin dożylnych (IVIg). Istnieją doniesienia o pozytywnej odpowiedzi klinicznej po zastosowaniu wysokich dawek immunoglobulin dożylnych u pacjentów z ciężkim TBE, zwłaszcza w późniejszej fazie choroby.26 Przykładowo, u pacjenta z agammaglobulinemią sprzężoną z chromosomem X (XLA) i ciężkim TBE, który został leczony osoczem zawierającym przeciwciała przeciwko wirusowi TBE, obserwowano poprawę stanu klinicznego bez widocznych działań niepożądanych.2728

Pacjenci po przebytym TBE nie powinni oddawać krwi przez 4 miesiące po zakończeniu choroby.29

Rokowanie i powikłania po TBE

Śmiertelność w przebiegu TBE wynosi około 0,5-2% w przypadku europejskiego podtypu wirusa, ale może być wyższa (5-10%) w przypadku podtypów syberyjskiego i dalekowschodniego.3031

Znaczna część pacjentów (do 60%) doświadcza niecałkowitego wyzdrowienia i długotrwałych powikłań po ostrym zakażeniu TBE.3233 W badaniu obejmującym 298 pacjentów, u 59,1% obserwowano niecałkowite wyzdrowienie przy wypisie ze szpitala, a u 27% utrzymywały się objawy bez oczekiwania na pełne wyzdrowienie.34

Najczęstsze długotrwałe powikłania obejmują:3536

  • Zmęczenie (17%)
  • Osłabienie (13,4%)
  • Zaburzenia koncentracji (13%)
  • Zaburzenia równowagi (12%)
  • Bóle głowy
  • Zaburzenia pamięci
  • Zaburzenia snu
  • Objawy neuropsychiatryczne

Niedowłady często towarzyszą zanikowi mięśni. U pacjentów z zapaleniem mózgu i rdzenia kręgowego zaburzenia czuciowe, niedowłady i upośledzenie pamięci oraz koncentracji mogą utrzymywać się przez kilka miesięcy.37

Powrót do zdrowia następuje najszybciej w ciągu pierwszych 24 miesięcy od wystąpienia objawów, ale może trwać przez cały okres obserwacji.38 U dzieci przebieg choroby jest zazwyczaj łagodniejszy, z lepszym rokowaniem – pełne wyzdrowienie zgłasza 94,9% dzieci w porównaniu do 63,8% dorosłych.3940

Profilaktyka i zapobieganie TBE

Szczepienia przeciwko TBE

Szczepienie jest najskuteczniejszą metodą zapobiegania TBE.4142 W sierpniu 2021 r. FDA zatwierdziła szczepionkę przeciwko TBE o nazwie TICOVAC (produkowaną przez Pfizer) dla osób w wieku 1 roku i starszych.43 Szczepionka ta jest również dostępna w wielu innych krajach, gdzie występuje wirus TBE.44

Schemat szczepienia obejmuje:4546

  • Serię podstawową składającą się z trzech dawek (przy czym drugą dawkę podaje się 14 dni do 3 miesięcy po pierwszej, a trzecią dawkę 5-12 miesięcy po pierwszej)
  • Dawkę przypominającą (czwartą dawkę) po 3 latach od zakończenia podstawowego schematu szczepienia, jeśli utrzymuje się ryzyko narażenia na wirusa TBE
  • Kolejne dawki przypominające co 5 lat dla osób poniżej 60 roku życia i co 3 lata dla osób powyżej 60 roku życia

4748

Schemat szczepienia powinien zostać zakończony co najmniej tydzień przed potencjalnym narażeniem na wirusa TBE.49

Najczęstsze działania niepożądane po szczepionce TicoVac to:5051

  • U osób w wieku 1-15 lat: bolesność miejscowa (18,1%), ból w miejscu wstrzyknięcia (11,2%), ból głowy (11,1%), gorączka (9,6%) i niepokój (9,1%)
  • U osób w wieku 16-65 lat: bolesność miejscowa (29,9%), ból w miejscu wstrzyknięcia (13,2%), zmęczenie (6,6%), ból głowy (6,3%) i ból mięśni (5,1%)

Wskazania do szczepień przeciwko TBE

Szczepienia przeciwko TBE są zalecane dla:525354

  • Osób mieszkających na obszarach endemicznych TBE
  • Osób podróżujących do obszarów endemicznych, którzy planują aktywności na świeżym powietrzu (camping, piesze wycieczki, wędkowanie, jazda na rowerze)
  • Osób z grup zawodowego ryzyka (leśnicy, rolnicy, wojskowi)
  • Osób przebywających długotrwale na terenach leśnych lub wiejskich w krajach występowania wirusa

Światowa Organizacja Zdrowia (WHO) zaleca szczepienia dla wszystkich grup wiekowych, w tym dzieci, na obszarach o wysokiej endemiczności (≥5 przypadków/100 000 osób rocznie).5556

Inne metody zapobiegania

Oprócz szczepień, istotne są również niespecyficzne środki zapobiegawcze:5758

  • Stosowanie środków odstraszających kleszcze zawierających DEET
  • Noszenie odzieży ochronnej (długie rękawy, długie spodnie, zakryte obuwie)
  • Unikanie obszarów z dużą liczbą kleszczy
  • Dokładne sprawdzanie ciała po pobycie na terenach endemicznych
  • Pasteryzacja mleka i unikanie spożywania niepasteryzowanych produktów mlecznych
  • Szybkie i prawidłowe usuwanie kleszczy w przypadku ukąszenia

Znaczenie kliniczne i epidemiologiczne TBE

TBE stanowi rosnący problem zdrowia publicznego w Europie i Azji.5960 Ze względu na brak specyficznego leczenia etiologicznego, znaczny odsetek pacjentów z niecałkowitym powrotem do zdrowia po ostrej chorobie oraz rosnącą zapadalność, TBE stanowi poważne wyzwanie dla systemów opieki zdrowotnej.61

Choroba wiąże się z wysokimi kosztami dla systemu opieki zdrowotnej i społeczeństwa, wynikającymi z hospitalizacji, rehabilitacji, absencji w pracy oraz długotrwałych powikłań.6263 Wysoki i czasami długotrwały poziom zachorowalności i wykorzystania opieki zdrowotnej podkreśla pilną potrzebę poprawy profilaktyki TBE.64

Istnieją dowody na niedostateczne diagnozowanie TBE w wielu krajach, co przyczynia się do niedoszacowania rzeczywistego obciążenia chorobą.6566 Badania wskazują, że bezobjawowe zakażenia wirusem TBE są powszechne, a zapadalność na zakażenie TBEV jest znacznie wyższa niż liczba zgłaszanych klinicznych przypadków TBE.67

Zwiększenie świadomości na temat TBE wśród lekarzy i ogółu społeczeństwa, a także promowanie szczepień ochronnych, są kluczowe dla zmniejszenia obciążenia tą chorobą.6869

Aspekty pielęgnacyjne i opieka nad pacjentem z TBE

Opieka nad pacjentem z TBE wymaga kompleksowego podejścia, dostosowanego do ciężkości objawów i fazy choroby.70

Opieka w łagodnych przypadkach

W przypadku łagodnego przebiegu choroby opieka obejmuje:7172

  • Monitorowanie podstawowych parametrów życiowych
  • Zapewnienie odpowiedniego nawodnienia
  • Podawanie leków przeciwgorączkowych i przeciwbólowych
  • Zapewnienie odpoczynku
  • Edukację pacjenta odnośnie przebiegu choroby i potencjalnych powikłań

Opieka w ciężkich przypadkach

Pacjenci z ciężkim przebiegiem TBE wymagają intensywnej opieki medycznej, która obejmuje:7374

  • Ścisłe monitorowanie stanu neurologicznego pacjenta
  • Monitorowanie ciśnienia śródczaszkowego
  • Zapobieganie powikłaniom neurologicznym (np. drgawki, obrzęk mózgu)
  • Wdrożenie odpowiednich środków w przypadku niemożności ochrony dróg oddechowych
  • Monitorowanie i leczenie ewentualnych zaburzeń oddychania
  • Zapobieganie odleżynom u pacjentów unieruchomionych
  • Profilaktykę przeciwzakrzepową
  • Kontrolę bólu
  • Wsparcie psychologiczne dla pacjenta i rodziny

Rehabilitacja i opieka długoterminowa

Po ostrej fazie choroby, wielu pacjentów wymaga długoterminowej opieki i rehabilitacji, która może obejmować:7576

  • Fizjoterapię – szczególnie w przypadku niedowładów i porażeń
  • Terapię zajęciową
  • Neurorehabilitację
  • Wsparcie psychologiczne i psychiatryczne
  • Terapię zaburzeń mowy
  • Regularne kontrole neurologiczne
  • Monitorowanie i leczenie powikłań długoterminowych

Opieka nad pacjentem z TBE powinna być zindywidualizowana i dostosowana do specyficznych potrzeb pacjenta, uwzględniając nasilenie objawów, obecność powikłań i współistniejących chorób.77

Rola personelu pielęgniarskiego w opiece nad pacjentem z TBE

Personel pielęgniarski odgrywa kluczową rolę w opiece nad pacjentami z TBE, zarówno w kontekście leczenia szpitalnego, jak i profilaktyki.78

Opieka szpitalna

W warunkach szpitalnych personel pielęgniarski odpowiada za:7980

  • Regularne monitorowanie parametrów życiowych pacjenta
  • Ocenę stanu neurologicznego (poziom świadomości, objawy oponowe, funkcje motoryczne)
  • Podawanie leków zgodnie z zaleceniami lekarskimi
  • Zapewnienie odpowiedniego nawodnienia i odżywienia
  • Zapobieganie powikłaniom unieruchomienia (odleżyny, zakrzepica)
  • Asystowanie przy procedurach diagnostycznych (np. punkcja lędźwiowa)
  • Monitorowanie pod kątem oznak podwyższonego ciśnienia śródczaszkowego
  • Zapewnienie komfortu i zmniejszenie lęku pacjenta

Edukacja i profilaktyka

Personel pielęgniarski odgrywa istotną rolę w edukacji pacjentów i społeczeństwa w zakresie:8182

  • Informowania o ryzyku TBE na obszarach endemicznych
  • Promowania szczepień przeciwko TBE dla osób z grup ryzyka
  • Edukacji na temat metod zapobiegania ukąszeniom kleszczy
  • Instruowania o prawidłowym usuwaniu kleszczy
  • Informowania o objawach TBE wymagających konsultacji medycznej
  • Uświadamiania o ryzyku związanym ze spożywaniem niepasteryzowanych produktów mlecznych

Czujność kliniczna

Personel pielęgniarski powinien zachować czujność kliniczną i rozważyć możliwość TBE u pacjentów z odpowiednimi objawami, szczególnie jeśli:8384

  • Przebywali na obszarach, gdzie występują kleszcze
  • Uczestniczyli w aktywnościach na świeżym powietrzu w obszarach leśnych
  • Zgłaszają ukąszenie kleszcza w wywiadzie
  • Prezentują objawy neurologiczne, szczególnie w sezonie aktywności kleszczy

W przypadku podejrzenia TBE, pacjenci z objawami neurologicznymi powinni być pilnie skierowani do szpitala.85

Znaczenie kliniczne TBE w praktyce medycznej

TBE stanowi istotne wyzwanie kliniczne ze względu na brak specyficznego leczenia i potencjalne długotrwałe powikłania.86 Właściwa opieka medyczna i pielęgniarska może znacząco wpłynąć na przebieg choroby i jakość życia pacjentów.87

Kluczowe aspekty w praktyce medycznej obejmują:8889

  • Wczesne rozpoznanie i diagnostykę przypadków
  • Właściwe monitorowanie pacjentów pod kątem powikłań
  • Kompleksową opiekę wspierającą dostosowaną do nasilenia objawów
  • Długoterminowe monitorowanie pacjentów po ostrej fazie choroby
  • Aktywną promocję szczepień ochronnych w grupach ryzyka
  • Edukację pacjentów w zakresie profilaktyki i wczesnego rozpoznawania objawów

Pomimo że całkowite ryzyko zakażenia TBE jest stosunkowo niskie, choroba ta powinna być brana pod uwagę w diagnostyce różnicowej u pacjentów z objawami neurologicznymi, szczególnie podczas sezonu aktywności kleszczy i na obszarach endemicznych.90

Zapobieganie poprzez szczepienia i unikanie ukąszeń kleszczy pozostaje najskuteczniejszą strategią w kontrolowaniu rozprzestrzeniania się TBE i zmniejszaniu obciążenia chorobą.91

    https://pmc.ncbi.nlm.nih.gov/articles/PMC8306415/
    Tick-borne encephalitis (TBE) virus is a major cause of central nervous system infections in endemic countries. Here, we present clinical and laboratory characteristics of a large international cohort of patients with confirmed TBE using a uniform clinical protocol. Patients were recruited in eight centers from six European countries between 2010 and 2017. A detailed description of clinical signs and symptoms was recorded. The obtained information enabled a reliable classification in 553 of 555 patients: 207 (37.3%) had meningitis, 273 (49.2%) meningoencephalitis, 15 (2.7%) meningomyelitis, and 58 (10.5%) meningoencephalomyelitis; 41 (7.4%) patients had a peripheral paresis of extremities, 13 (2.3%) a central paresis of extremities, and 25 (4.5%) had single or multiple cranial nerve palsies. Five (0.9%) patients died during acute illness. Outcome at discharge was recorded in 298 patients. Of 176 (59.1%) patients with incomplete recovery, 80 (27%) displayed persisting symptoms or signs without recovery expectation. This study provides further evidence that TBE is a severe disease with a large proportion of patients with incomplete recovery. We suggest monitoring TBE in endemic European countries using a uniform protocol to record the full clinical spectrum of the disease.

    For the first time, scientists have confirmed tick-borne encephalitis in British patients with no travel history, proving that the virus is now spreading locally. […] Tick-borne encephalitis (TBE), a virus spread through tick bites, has been confirmed in British patients. […] Most infections with TBEV cause no symptoms, but in some cases, the disease progresses to encephalitis, leading to brain inflammation, neurological damage, and, in rare cases, death. […] The study confirmed the incidence of TBEV in the U.K. and reported that the virus had caused locally acquired human infections. […] Both confirmed patients developed initial flu-like symptoms followed by neurological symptoms, including ataxia and confusion, but recovered with supportive care.

    This page provides information on the testing available for Tick-borne encephalitis (TBE), caused by the Tick-borne encephalitis virus (TBEV). Testing for TBE and the TBEV is not performed at PHOs laboratory and requests for serology and polymerase chain reaction (PCR) tests are referred to the National Microbiology Laboratory (NML) in Winnipeg. […] The diagnosis of TBE is based on the detection of specific IgM antibodies in cerebrospinal fluid (intrathecal production) and/or serum. TBE antibodies appear within 6 days after symptom onset and can be detected when neurological symptoms are present. Specific IgM antibodies can persist for up to 10 months in individuals who acquired the infection naturally. […] Testing for TBEV requires prior approval by PHOs laboratory. Contact PHOs Laboratory Customer Service Centre at 416-235-6556/1-877-604-4567 or the After-Hours Emergency Duty Officer at 416-605-3113 prior to sample collection and submission.

    Tick-borne encephalitis is a viral infection spread primarily through tick bites. […] TBE is a viral infection involving the central nervous system. […] If you experience any of these symptoms, speak with a doctor or call your local emergency number right away. These symptoms can indicate serious disease that requires immediate medical attention. […] The best way to protect yourself is to get the TBE vaccine. […] Therapy involves supportive care to manage symptoms and complications. […] People experiencing flu-like symptoms may find relief by: getting plenty of rest, drinking fluids and staying hydrated, taking over-the-counter (OTC) pain and cold medications. […] People who develop serious infection involving the central nervous system often require treatment in a hospital. […] Most people with TBE will recover. But, up to one-third of people with TBE may experience long-term complications. […] Speak with a doctor about TBE vaccination if you plan to travel to high-risk areas.

    Since 2001, 20 TBE cases have been diagnosed among U.S. adult and pediatric civilian and military persons who traveled to parts of Europe, Russia and China. Clinical manifestations of TBE virus infection can include febrile illness or neurologic disease, including meningitis (inflammation of the lining of the brain), encephalitis (inflammation of the brain), or meningoencephalomyelitis (inflammation of the lining of the brain, the brain and the spinal cord). No specific treatment is available and management is supportive. Mortality and sequelae (consequences of the disease) rates vary with different subtypes of TBE virus, with mortality rates of 120%, and sequelae rates of 1050%, reported from different areas. TBE vaccines have been available internationally for about 40 years, but until recently no TBE vaccine had been licensed in the United States and prevention has focused on personal protective measures to prevent tick bites.

    Given the spread of TBEV to UK shores, the evaluation of suitable public health measures is required. […] Currently, there are two inactivated European vaccines utilised, namely Encepur (German) and FSME-Immun (Austrian). […] The vaccination schedule for both vaccines includes three primary doses within the first year, with booster doses at 3 years, and additional doses advised in those <5 years and >60 years to protect against waning immunity. […] Given this, the need for a TBE vaccination within the UK is uncertain, given the limited understanding of its epidemiology and distribution to make sound economic evaluations.

    A press release from Public Health England (PHE) recently confirmed that the tick-borne encephalitis (TBE) virus has been detected for the first time in two parts of England (PHE, 2019a). […] Health professionals need to have the knowledge to put public health stories such as this into perspective and an awareness of patients presenting with possible TBE symptoms. […] TBE is an infection spread by tick bites, but it can also be acquired from consumption of raw (unpasteurised) milk or dairy products (Centers for Disease Control and Prevention (CDC), 2020). […] Most TBE virus infections resulting from tick bites are acquired through activities in forest areas, such as camping, hiking, fishing and bicycling, and from occupations such as forestry or military training (CDC, 2020).

    What do nurses need to know about tick-borne encephalitis virus (TBEV), which recently arrived in the UK? […] Spread by the bite of an infected tick, TBEV can lead to a spectrum of illness including meningitis and encephalitis (swelling of the brain). […] The importance of public health advice from nurses to protect people from being bitten by ticks and the availability of a vaccine is also covered. […] Be aware of the importance of advice on avoiding tick bites, as this can protect from TBEV and other tick-borne illness. […] Be vigilant and consider the possibility of TBEV if seeing a patient with relevant symptoms. Ask them if they have been outside in grassy areas working or enjoying the countryside. […] Refer on and seek specialist advice when a patient has possible symptoms that cause concern, especially neurological ones. Patients with neurological signs should be referred to hospital as an emergency.

    https://pmc.ncbi.nlm.nih.gov/articles/PMC4419106/
    Tick-borne encephalitis is an infection of central nervous system caused by tick-borne encephalitis virus transmitted to humans predominantly by tick bites. […] A post-encephalitic syndrome, causing long-lasting morbidity that often affects the quality of life develops in up to 50% of patients after acute tick-borne encephalitis. […] There is no specific antiviral treatment for tick-borne encephalitis. Vaccination can effectively prevent the disease and is indicated for persons living in or visiting tick-borne encephalitis endemic areas. […] Treatment is based on the symptomatic measures. However, TBE can be successfully prevented by safe and highly effective vaccine. […] There is no specific antiviral treatment for TBE. Patients as a rule need hospitalization and supportive care based on the severity of signs/symptoms, and usually encompasses administration of antipyretics, analgesics, antiemetics, maintenance of water and electrolyte balance, and if necessary administration of anticonvulsive agents.

    It will therefore be important to develop clear decision trees for TBE diagnostic testing, which can help to align testing processes across Germany. […] Findings suggest that patients with typical TBE symptoms are likely under-tested, indicating a potential under-diagnosis of TBE in Germany. To ensure appropriate case identification, TBE testing should be more consistently integrated into routine practice for all patients who present with relevant symptoms and those exposed to common risk factors, especially tick bite.

    Overall, the study provided the first definitive evidence of locally acquired TBE in the U.K., highlighting the need for increased surveillance and public awareness. […] The researchers believe that while the overall risk remains low, TBE should now be considered in cases of unexplained encephalitis, even in patients without recent travel. […] Furthermore, public health efforts should include tick bite prevention education, with campaigns previously focused on Lyme disease now incorporating awareness of TBEV.

    There is no specific antiviral treatment for TBE. Patients as a rule need hospitalization, supportive care, symptomatic treatment based on the presence and severity of signs/symptoms and therapy of neurologic and systemic complications. […] The symptomatic treatment usually includes antipyretics, analgesics, antiemetics, maintenance of fluid and electrolyte balance, and if necessary administration of anticonvulsive agents and treatment of cerebral edema. […] Active immunization is the most effective and reliable way to prevent TBE. […] Vaccination strategies need to incorporate risk assessments for a particular region. […] In highly endemic TBE regions (5 cases/100,000/year) vaccination should be offered to whole population, including children, whereas in regions with a moderate or low TBE incidence (5 cases/100,000/year), immunization has to target individuals at risk, i.e., those having outdoor activities or working under high-risk conditions.
