Rotawirus
Etiologia i przyczyny
Rotawirus, należący do rodziny Reoviridae, to dwuniciowy RNA wirus o charakterystycznym wyglądzie koła, będący główną przyczyną ciężkiego zapalenia żołądka i jelit u niemowląt i małych dzieci na całym świecie. Genom wirusa składa się z 11 segmentów RNA, a białka VP7 (G) i VP4 (P) na zewnętrznej warstwie kapsydu indukują przeciwciała neutralizujące, kluczowe dla ochrony immunologicznej. Rotawirus zakaża enterocyty jelita cienkiego, prowadząc do ich uszkodzenia, zaburzeń wchłaniania oraz nasilenia biegunki i wymiotów poprzez mechanizmy takie jak działanie białka NSP4, sygnalizację ADP i uwalnianie serotoniny (5-HT). Wirus jest wysoce zakaźny, przenoszony głównie drogą fekalno-oralną, z kałem zawierającym ponad 10 bilionów cząstek zakaźnych na gram, obecny już 2 dni przed objawami i utrzymujący się do 10 dni po ich ustąpieniu. Szczególnie narażone na ciężki przebieg choroby są dzieci poniżej 5 roku życia, zwłaszcza między 3 a 35 miesiącem życia, niemowlęta z niską masą urodzeniową, osoby z obniżoną odpornością oraz osoby starsze.
Etiologia Rotawirusów
Rotawirus (z łac. „rota” – koło) to wirus o charakterystycznym wyglądzie koła pod mikroskopem elektronowym, należący do rodziny Reoviridae, posiadający dwuniciowy RNA. Został po raz pierwszy zidentyfikowany jako przyczyna biegunki w 1973 roku przez Ruth Bishop i jej zespół podczas badań mikroskopowych dwunastnicy dzieci z ciężką biegunką12. Do 1980 roku rotawirus został uznany za najczęstszą przyczynę ciężkiego zapalenia żołądka i jelit u niemowląt i małych dzieci na całym świecie3.
Genom rotawirusa składa się z 11 segmentów dwuniciowego RNA zamkniętych w dwuwarstwowej kapsydzie45. Zewnętrzna warstwa kapsydu zawiera dwa ważne białka: VP7 (białko G) i VP4 (białko P), które indukują przeciwciała neutralizujące, odgrywające istotną rolę w ochronie immunologicznej6. Rotawirusy są klasyfikowane do różnych genotypów według ekspresji określonych białek NSP47.
Istnieje co najmniej 7 antygenowo odrębnych serogrup rotawirusów (A, B, C, D, E, F, G), ale większość zakażeń u ludzi (ponad 90%) jest powodowana przez grupę A (RVA)89. Chociaż większość rotawirusów powodujących biegunkę u dzieci na całym świecie należy do serogrupy A, rotawirusy z grup B i C również mogą wywoływać choroby u ludzi10.
Patofizjologia zakażenia rotawirusowego
Rotawirus wywołuje chorobę poprzez zakażenie enterocytów (komórek wyściełających nabłonek) w jelicie cienkim11. Wirus atakuje i niszczy komórki wyściełające jelito cienkie, zwane enterocytami, które pomagają w absorpcji składników odżywczych z pokarmu12. Ponieważ te komórki odgrywają rolę w trawieniu węglowodanów oraz wchłanianiu płynów i elektrolitów, zakażenia rotawirusowe prowadzą do zaburzeń wchłaniania przez nieprawidłową hydrolizę węglowodanów i wydzielanie płynów z jelita13.
Co ciekawe, badania wykazały, że rotawirus zakaża tylko niewielką część podatnych komórek, ale jego wpływ wykracza poza bezpośrednio zakażone komórki. Zakażone komórki wysyłają sygnały do sąsiednich niezakażonych komórek, zakłócając ich funkcje i nasilając biegunkę i wymioty14. Wykazano, że zakażone rotawirusem komórki sygnalizują niezakażonym komórkom za pomocą ADP (adenozynodwufosforanu), co przyczynia się do nasilenia choroby15. Wykorzystując wewnątrzkomórkowe fale wapnia, rotawirus wzmacnia swoją zdolność do wywoływania choroby poza komórkami, które bezpośrednio zakaża16.
Rotawirus może również stymulować uwalnianie 5-HT (serotoniny) z ludzkich komórek enterochromafinowych i aktywować ośrodek wymiotny w ośrodkowym układzie nerwowym, co wyjaśnia mechanizm wywoływania wymiotów17.
Drogi szerzenia się rotawirusów
Rotawirus jest wysoce zakaźny i szerzy się głównie drogą fekalno-oralną1819. Rezerwuarem rotawirusa jest przewód pokarmowy i kał zakażonych ludzi20. Rotawirusy są wydalane w wysokim stężeniu w kale zakażonych osób – kał zakażonej osoby może zawierać ponad 10 bilionów cząstek zakaźnych na gram21.
Rotawirus jest obecny w kale zakażonej osoby już dwa dni przed wystąpieniem objawów i utrzymuje się do 10 dni po złagodzeniu objawów2223. Wirus łatwo rozprzestrzenia się przez kontakt ręka-usta przez cały ten czas, nawet jeśli zakażona osoba nie ma objawów24.
Transmisja rotawirusa odbywa się na kilka sposobów:
- Poprzez bezpośredni kontakt z zakażoną osobą – gdy zakażona osoba nie myje odpowiednio rąk po skorzystaniu z toalety, a następnie dotyka przedmiotów lub powierzchni, z którymi mogą mieć kontakt inne osoby25
- Poprzez dotykanie przedmiotów lub powierzchni zanieczyszczonych wirusem, takich jak klamki, krany, deski sedesowe i zabawki26
- Poprzez spożywanie zanieczyszczonej żywności lub wody27
- W rzadkich przypadkach, przez kropelki w powietrzu, szczególnie w placówkach opieki zdrowotnej28
Wirus może pozostać zakaźny na powierzchniach, które nie zostały zdezynfekowane, przez tygodnie lub miesiące29. Jest niezwykle odporny w środowisku i może przetrwać miesiące w kale w temperaturze pokojowej30.
Czynniki ryzyka zakażenia rotawirusem
Rotawirus może zakazić każdego, niezależnie od wieku i statusu społeczno-ekonomicznego, jednak pewne grupy są szczególnie narażone na ciężki przebieg infekcji3132.
Grupy wysokiego ryzyka
Następujące grupy są szczególnie podatne na zakażenie rotawirusem lub jego ciężki przebieg:
- Niemowlęta i dzieci poniżej 5 roku życia, ze szczególnym uwzględnieniem dzieci między 3 a 35 miesiącem życia3334
- Niemowlęta z niską masą urodzeniową (poniżej 2500 gramów)3536
- Dzieci uczęszczające do żłobków i przedszkoli3738
- Gospodarstwa domowe z innym dzieckiem poniżej 24 miesiąca życia3940
- Osoby z obniżoną odpornością4142
- Osoby starsze43
Niektóre badania wskazują również na dodatkowe czynniki ryzyka, takie jak karmienie mlekiem modyfikowanym zamiast karmienia piersią oraz posiadanie młodych lub niedoświadczonych opiekunów44.
Powiązania epidemiologiczne
Rotawirus charakteryzuje się wysoką zakaźnością, o czym świadczy niemal powszechne zakażenie dzieci do 5 roku życia w erze przed wprowadzeniem szczepionek45. Przed wprowadzeniem szczepionek prawie każde dziecko w Stanach Zjednoczonych i na całym świecie przeszło co najmniej jedno zakażenie rotawirusem przed ukończeniem 5 lat4647.
W erze przed wprowadzeniem szczepionki, szacowano, że co roku w Stanach Zjednoczonych występowało 2,7 miliona zakażeń rotawirusowych, a 95% dzieci przechodziło co najmniej jedno zakażenie rotawirusem do 5 roku życia48. Rotawirus odpowiadał za 30% do 50% wszystkich hospitalizacji z powodu zapalenia żołądka i jelit wśród dzieci poniżej 5 roku życia49.
Rotawirus powszechnie szerzy się w rodzinach, szpitalach i placówkach opieki nad dziećmi50. W placówkach opieki nad dziećmi rotawirus powoduje 20-45% ognisk choroby biegunkowej51.
Odporność i reinfekcje
Odporność po zakażeniu rotawirusem nie jest trwała. Korelaty immunologiczne ochrony przed rotawirusem nie są w pełni poznane, jednak przeciwciała surowicze i błonowe przeciwko białkom VP7 i VP4 są prawdopodobnie istotne dla ochrony przed chorobą52.
Możliwe jest wielokrotne zakażenie rotawirusem, nawet jeśli dana osoba została zaszczepiona5354. Jest to spowodowane kilkoma czynnikami:
- Istnieje kilka różnych szczepów rotawirusa
- Odporność rozwija się z każdym zakażeniem, więc kolejne infekcje są zwykle mniej dotkliwe55
- Ani naturalne zakażenie rotawirusem, ani szczepienie nie zapewniają pełnej ochrony przed przyszłymi zakażeniami56
Istotne jest, że szczepione dzieci rzadziej chorują na rotawirusa, a jeśli już zachorują, przebieg choroby jest łagodniejszy5758. Szczepienia przeciwko rotawirusowi mogą zapobiec zachorowaniu u około 70-85% dzieci, a u pozostałych znacząco łagodzą objawy5960.
Mechanizmy immunologiczne
Odporność na rotawirusa rozwija się w złożony sposób. Po zakażeniu organizm produkuje przeciwciała przeciwko białkom wirusa, szczególnie przeciwko białkom VP7 i VP4 znajdujących się na zewnętrznej warstwie kapsydu61.
Jednak odporność nie jest krzyżowa między serogrupami i jest niepełna między serowariantami62. Oznacza to, że przebycie zakażenia jednym typem rotawirusa nie chroni w pełni przed zakażeniem innym typem.
Interesujące jest, że szczepionki monowalentne (zawierające szczep G1P[8] ludzkiego rotawirusa) i pięciowalentne wykazują podobny stopień skuteczności w ochronie przed zakażeniem homotypowymi i heterotypowymi szczepami rotawirusa63.
Mikrobiom jelitowy może również wpływać na skuteczność szczepionek przeciwko rotawirusowi, co sugeruje, że skład bakterii jelitowych może odgrywać rolę w odpowiedzi immunologicznej na szczepionkę64.
Czynniki wpływające na patogenność rotawirusa
Patogenność rotawirusa jest determinowana przez wiele czynników, które wpływają na jego zdolność do wywoływania choroby i ciężkość jej przebiegu.
Mechanizmy molekularne
Rotawirus głównie zakaża enterocyty i wywołuje biegunkę poprzez:
- Niszczenie enterocytów absorbujących, co prowadzi do zaburzeń wchłaniania65
- Stymulację wydzielania jelitowego przez niestrukturalne białko rotawirusa 4 (NSP4)66
- Aktywację jelitowego układu nerwowego67
- Wykorzystanie międzykomórkowych fal wapniowych do amplifikacji zdolności wywoływania choroby poza bezpośrednio zakażonymi komórkami68
Niedawne badania ujawniły wcześniej nieznane role ADP w zakażeniu i replikacji rotawirusa, wskazując na ADP jako ważny czynnik wyzwalający wiele czynników zaangażowanych w ciężką biegunkę i wymioty powodowane przez rotawirusa69.
Wpływ innych czynników
Na zakażenie rotawirusem i jego przebieg mogą wpływać również inne czynniki:
- Wiek – niemowlęta i małe dzieci są najbardziej podatne na ciężki przebieg choroby70
- Stan układu odpornościowego – osoby z osłabionym układem odpornościowym są bardziej narażone na ciężki przebieg choroby71
- Odporność matczyna – wysokie poziomy matczynej odporności przeciwrotawirusowej (w postaci przeciwciał IgA w mleku matki i przeciwciał IgG przechodzących przez łożysko) mogą przyczyniać się do niepowodzenia serokonwersji po szczepieniu72
- Czynniki wirusowe – różne szczepy rotawirusa mogą mieć różny potencjał patogenny73
- Czynniki związane z dzieckiem – takie jak niedożywienie czy współistniejące infekcje74
Powikłania pozajelitowe rotawirusa
Chociaż zakażenie rotawirusem pierwotnie uważano za ograniczone do przewodu pokarmowego, wiele doniesień wykazało, że może ono powodować objawy pozajelitowe, w tym:
- Różne zaburzenia neurologiczne, w tym encefalopatie i zapalenie mózgu7576
- Zapalenie wątroby i cholestazę
- Zapalenie trzustki
- Cukrzycę typu 1
- Choroby układu oddechowego
- Zapalenie mięśnia sercowego
- Niewydolność nerek
- Małopłytkowość77
Mechanizmy, poprzez które zakażenie rotawirusem powoduje te powikłania, nie są w pełni znane. Wykrycie antygenów i RNA rotawirusa w płynie mózgowo-rdzeniowym pacjentów z powikłaniami ze strony ośrodkowego układu nerwowego (OUN) potwierdza teorię bezpośredniej inwazji wirusa do OUN78.
Jednak próbki płynu mózgowo-rdzeniowego nie zawsze są dodatnie pod kątem antygenu i/lub RNA rotawirusa w przypadkach powikłań ze strony OUN. Biorąc pod uwagę te obserwacje, przypuszcza się, że powikłania ze strony OUN mogą być spowodowane bezpośrednią inwazją wirusa do OUN i/lub krążącymi mediatorami o szkodliwym wpływie na OUN79.
| Mechanizm patogenezy | Opis | Implikacje kliniczne |
|---|---|---|
| Uszkodzenie enterocytów | Wirus atakuje i niszczy komórki wyściełające jelito cienkie | Zaburzenia wchłaniania, biegunka |
| Działanie białka NSP4 | Niestrukturalne białko 4 stymuluje wydzielanie jelitowe | Nasilenie biegunki sekrecyjnej |
| Aktywacja układu nerwowego jelita | Wpływ na neurony enteryczne | Zaburzenia perystaltyki, biegunka |
| Sygnalizacja ADP | Zakażone komórki sygnalizują niezakażonym komórkom za pomocą ADP | Amplifikacja odpowiedzi, nasilenie objawów |
| Uwalnianie serotoniny (5-HT) | Stymulacja komórek enterochromafinowych | Aktywacja ośrodka wymiotnego, wymioty |
| Inwazja pozajelitowa | Przedostawanie się wirusa poza jelito | Powikłania pozajelitowe (neurologiczne, wątrobowe itd.) |
Profilaktyka i zapobieganie zakażeniom rotawirusowym
Zakażeniom rotawirusowym można zapobiegać poprzez szczepienia oraz przestrzeganie zasad higieny, choć te drugie mają ograniczoną skuteczność ze względu na wysoką zakaźność wirusa.
Szczepienia przeciwko rotawirusowi
Szczepienie jest najbardziej skutecznym środkiem zapobiegawczym i jest bardzo skuteczne w zapobieganiu ciężkim chorobom rotawirusowym u małych dzieci i niemowląt80. Dostępne są dwie główne szczepionki przeciwko rotawirusowi zatwierdzone do stosowania w Unii Europejskiej od 2006 roku:
- RotaTeq – szczepionka pięciowalentna, opracowana z szczepu rotawirusa pierwotnie wyizolowanego od cielęcia81
- Rotarix – szczepionka monowalentna, zawierająca jeden typ rotawirusa pierwotnie wyizolowany od człowieka i osłabiony w laboratorium82
Szczepionki te dostarczają ochronę przed gastroenteritis wywołanym przez zakażenie rotawirusem83. Są one wysoce skuteczne (85% do 98%) w zapobieganiu ciężkim rotawirusowym chorobom u niemowląt i małych dzieci, w tym zakażeniom rotawirusowym wymagającym hospitalizacji84.
Skuteczność szczepionek została dobrze udokumentowana:
- Około 70-85% dzieci, które otrzymują szczepionkę przeciwko rotawirusowi, nie zachoruje na rotawirusa8586
- Przez około pierwszy rok życia niemowlęcia, szczepionka przeciwko rotawirusowi zapewnia 85-98% ochrony przed ciężkim przebiegiem choroby rotawirusowej i hospitalizacją z powodu choroby rotawirusowej, oraz 74-87% ochrony przed chorobą rotawirusową o dowolnym nasileniu87
- Od czasu wprowadzenia szczepionki w 2006 roku, zachorowania i zgony z powodu rotawirusa znacznie się zmniejszyły88
Obie szczepionki zostały dokładnie przetestowane u tysięcy niemowląt i są uważane za bezpieczne i skuteczne89. Jednak oceny poszczepieniowe szczepionki RV5 i/lub szczepionki RV1 w niektórych krajach o średnich i wysokich dochodach wykazały niski poziom zwiększonego ryzyka wgłobienia jelita po szczepieniu90.
Higiena i inne środki zapobiegawcze
Ze względu na wszechobecność wirusa i jego wysoką zakaźność, bardzo trudne lub nawet niemożliwe jest zapobieganie zakażeniu rotawirusem u osób, które nie zostały zaszczepione. Zanieczyszczenie jest możliwe nawet w miejscach o doskonałych standardach higieny i warunków sanitarnych91.
Niemniej jednak, następujące środki higieniczne mogą pomóc w ograniczeniu rozprzestrzeniania się rotawirusa:
- Dokładne mycie rąk mydłem i wodą po skorzystaniu z toalety lub zmianie pieluszek92
- Dezynfekcja powierzchni potencjalnie zanieczyszczonych wirusem
- Izolacja osób zakażonych, szczególnie w placówkach opieki nad dziećmi
Warto zauważyć, że ogólna częstość występowania zakażeń rotawirusowych prawdopodobnie nie ulegnie zmianie nawet jeśli nastąpi poprawa zaopatrzenia w wodę, warunków sanitarnych, odżywiania osobistego, warunków mieszkaniowych i edukacji zdrowotnej publicznej, co sugeruje, że transmisja wirusa może odbywać się również drogami pozakałowymi93.
Z tego powodu szczepienia są uważane za najbardziej efektywny kosztowo środek zapobiegania zakażeniom rotawirusowym9495.

- #1 Rotavirus – Wikipediahttps://en.wikipedia.org/wiki/Rotavirus
Rotaviruses are the most common cause of diarrhoeal disease among infants and young children. […] Nearly every child in the world is infected with a rotavirus at least once by the age of five. […] Immunity develops with each infection, so subsequent infections are less severe. […] The virus is transmitted by the faecaloral route. […] It infects and damages the cells that line the small intestine and causes gastroenteritis (which is often called „stomach flu” despite having no relation to influenza). […] Although rotavirus was discovered in 1973 by Ruth Bishop and her colleagues by electron micrograph images and accounts for approximately one third of hospitalisations for severe diarrhoea in infants and children, its importance has historically been underestimated within the public health community, particularly in developing countries.
- #2 Rotavirus infection-associated central nervous system complications: clinicoradiological features and potential mechanismshttps://www.e-cep.org/journal/view.php?number=20125555504
Rotavirus was first reported in 1973 after the visualization of viral particles under an electron microscope in the duodenal mucosa of 9 children with acute nonbacterial gastroenteritis. […] Rotavirus infection was initially considered confined to the gastrointestinal tract; however, many reports have shown that it may cause extraintestinal manifestations including various neurological disorders, hepatitis, cholestasis, pancreatitis, type 1 diabetes, respiratory illness, myocarditis, renal failure, and thrombocytopenia. […] Rotavirus is a common cause of acute encephalopathy and encephalitis in children. […] Although rotavirus infection can involve CNS complications with various manifestations, such as impaired consciousness, seizures, and mutism, the underlying mechanisms by which rotavirus infection causes these complications are largely unknown.

Rotavirus was first identified as the cause of diarrhea in 1973. […] By 1980, rotavirus was recognized as the most common cause of severe gastroenteritis in infants and young children in the United States. […] In the prevaccine era, the majority of children were infected by age 5 years, and rotavirus was responsible for up to 500,000 deaths among children annually worldwide. […] Rotavirus is a double-stranded RNA virus of the family Reoviridae. […] The outermost shell contains two important proteins: VP7, or G-protein, and VP4, or P-protein. […] VP7 and VP4 induce neutralizing antibodies that are believed to be involved in immune protection. […] The immune correlates of protection from rotavirus are not fully understood. […] Serum and mucosal antibodies against VP7 and VP4 are probably important for protection from disease.
- #4 Rotavirus: Practice Essentials, Background, Pathophysiologyhttps://emedicine.medscape.com/article/803885-overview
Rotavirus is one of several viruses known to cause a self-limited gastroenteritis. Fluid stool losses may be dramatic, and death from dehydration is not uncommon, particularly in developing countries. […] Rotavirus is one of several viruses known to cause gastroenteritis. The rotavirus genome consists of 11 segments of double-stranded RNA enclosed in a double-shelled capsid. It is classified in the Reoviridae family. Rotavirus is a self-limited infection. Fluid stool losses may be dramatic, and death from dehydration is not uncommon, particularly in developing countries. […] The most significant risk factor for rotavirus infection appears to be participation in group daycare, presumably because the virus is spread through fecal-oral contact by the children themselves and by the daycare workers who are responsible for diapering. Also, fomites serve as important vectors for viral transmission. […] Rotavirus can cause illness in adults and children. However, adults are often asymptomatic or less severely affected.
- #5 Disease Caused by Rotavirus Infectionhttps://pmc.ncbi.nlm.nih.gov/articles/PMC4279035/
Although rotavirus vaccines are available, rotaviruses remain the major cause of childhood diarrheal disease worldwide. […] Despite declining child mortality and morbidity resulting from rotaviral gastroenteritis, rotavirus infection persists as the most common cause of hospitalization and mortality in children due to the severe diarrhea and dehydration that result from infection. […] Rotaviruses were first identified in animals in the 1960s and then were subsequently discovered in humans via electron microscopic examination of the duodenums of children who had severe diarrhea. […] Rotavirus is a member of the family Reoviridae and the genus Rotavirus. […] The rotavirus genome is composed of 11 RNA segments that encode for the VP1-VP4, VP6, and VP7 structural and NSP1-NSP6 non-structural viral proteins.

Rotaviruses are categorized into different genotypes according to the particular NSP4 proteins expressed. […] Rotavirus infection causes severe gastroenteritis in infants and young children worldwide. […] The majority of rotavirus-related deaths (80%) are found in resource-limited countries, such as those found in southern Asia and sub-Saharan Africa. […] Therefore, the overall incidence of rotavirus infection would not change even if improvements in water supplies, sanitation, personal nutrition, housing, and public health education were made, suggesting that viral transmission might occur via non-fecal routes. […] Vaccines are an effective and available measure for combating rotavirus disease and for preventing rotavirus infection. […] The societal costs resulting from rotavirus infection have been calculated for different countries.
- #8 Rotavirus – Wikipediahttps://en.wikipedia.org/wiki/Rotavirus
In addition to its impact on human health, rotavirus also infects other animals, and is a pathogen of livestock. […] Rotaviral enteritis is usually an easily managed disease of childhood, but among children under 5 years of age rotavirus caused an estimated 151,714 deaths from diarrhoea in 2019. […] The incidence and severity of rotavirus infections has declined significantly in countries that have added rotavirus vaccine to their routine childhood immunisation policies. […] Rotavirus is a genus of double-stranded RNA viruses in the family Reoviridae. […] The most common is RVA, and these rotaviruses cause more than 90% of rotavirus infections in humans.

Rotaviruses cause diarrhea in nursing and postweaned pigs, affecting primarily the small intestine. […] There are at least 7 antigenically distinct serogroups of rotaviruses (A, B, C, D, E, F, G) of which 4 (A, B, C, E) affect swine. […] Most is known about the more common group A rotaviruses. Group A is by far the most prevalent but type C has been associated with outbreaks. […] Immunity is not cross-protective between serogroups and is incomplete between serovarieties. […] Rotavirus as a consistent cause of diarrhea in post-weaned pigs would implicate poor sanitation, and disinfecting between groups of pigs would be warranted.

Rotaviruses are the single most important cause of severe diarrhoeal illness in infants and young children worldwide. […] Most rotaviruses causing diarrhoeal illness in children worldwide belong to serogroup A, but rotaviruses group B and C may also cause disease in humans. […] Severe RV GE disease may develop in any child. However, a limited number of risk factors for development of severe disease have been identified including low-birth-weight infants (2,500 g), another child 24 months of age in the household and severe immunodeficiency conditions. […] Rotaviruses are mainly transmitted from person-to-person through the faecal-oral route, but transmission may also occur through contaminated objects (e.g. door-handles, water-taps, toilet-seats and toys), airborne droplets and contaminated water or food. […] Two live attenuated vaccines for oral use providing prevention against rotavirus disease were authorised in the European Union in 2006; The indication for these vaccines is active immunization of infants for prevention of gastroenteritis due to rotavirus infection.

Rotavirus is a major cause of diarrhea and vomiting, especially in children, that results in approximately 128,000 deaths annually. […] The virus triggers the disease by infecting enterocyte cells in the small intestine, but only a fraction of the susceptible cells has the virus. […] The researchers connected their observation to a concept proposed in the mid-90s suggesting that rotavirus-infected cells send signals to neighboring uninfected cells that disrupt their function, promoting diarrhea and vomiting. […] Across the three model systems we consistently found evidence that rotavirus-infected cells signal uninfected cells with ADP and that this contributes to the severity of the disease, Chang-Graham said. […] Further studies revealed previously unknown roles of ADP on rotavirus infection and replication, shining a spotlight on ADP as an important trigger of the multiple factors involved in severe diarrhea and vomiting caused by rotavirus. […] Using intercellular calcium waves, rotavirus amplifies its ability to cause disease beyond the cells it directly infects. […] Our findings add a new and very potent signaling pathway into the causative mechanisms of rotavirus diarrhea, Hyser said.
- #12 What Is Rotavirus? Symptoms, Causes, Treatment, and Preventionhttps://www.webmd.com/children/what-is-rotavirus
Rotavirus is a virus that causes diarrhea and other intestinal symptoms. Its very contagious and is the most common cause of diarrhea in infants and young children worldwide. […] Rotavirus causes inflammation in the stomach and intestines. […] The illness is caused by a type of virus that was named rotavirus for its wheel-like appearance under a microscope. The Latin word for wheel is rota. […] These viruses are found throughout the world, and they spread easily from person to person. The virus invades and destroys cells in your intestinal lining called enterocytes, which help you absorb nutrients from food. This triggers the diarrhea that is a hallmark of rotavirus.
- #13 Rotavirus Infection Causes, Symptoms, Diagnosis and Treatment – Cura4Uhttps://cura4u.com/conditions/rotavirus-infection
Rotavirus is an infection of the gut caused by viruses. It belongs to the Reoviridae family. It is one of the common viruses known to cause self-limited gastroenteritis. […] Rotavirus fundamentally infects the cells of the small intestinal villi, particularly the cells that are close to the tips of the villi. As these specific cells have a role in the digestion of carbohydrates and the intestinal absorption of fluid and electrolytes, rotavirus infections result in malabsorption by defective hydrolysis of carbohydrates and fluid excretion from the intestine. […] Rotavirus germs are found in individuals’ feces and can transmit to other surfaces by unclean hands after using the bathroom or diaper changes. If these viruses come into contact with someone’s mouth, this is known as the fecal-oral spread.

Rotavirus is a major cause of diarrhea and vomiting, especially in children, that results in approximately 128,000 deaths annually. […] The virus triggers the disease by infecting enterocyte cells in the small intestine, but only a fraction of the susceptible cells has the virus. […] The researchers connected their observation to a concept proposed in the mid-90s suggesting that rotavirus-infected cells send signals to neighboring uninfected cells that disrupt their function, promoting diarrhea and vomiting. […] Across the three model systems we consistently found evidence that rotavirus-infected cells signal uninfected cells with ADP and that this contributes to the severity of the disease, Chang-Graham said. […] Further studies revealed previously unknown roles of ADP on rotavirus infection and replication, shining a spotlight on ADP as an important trigger of the multiple factors involved in severe diarrhea and vomiting caused by rotavirus. […] Using intercellular calcium waves, rotavirus amplifies its ability to cause disease beyond the cells it directly infects. […] Our findings add a new and very potent signaling pathway into the causative mechanisms of rotavirus diarrhea, Hyser said.

Rotavirus infections are a leading cause of severe, dehydrating gastroenteritis in children 5 years of age. […] Rotavirus primarily infects enterocytes and induces diarrhoea through the destruction of absorptive enterocytes (leading to malabsorption), intestinal secretion stimulated by rotavirus non-structural protein 4 and activation of the enteric nervous system. […] This study shows visualization of rotavirus as the causative agent of viral gastroenteritis and the associated histopathology. […] This report shows that rotavirus can stimulate 5-HT release from human enterochromaffin cells and activate the vomiting centre in the central nervous system. […] This study is the 2008 estimate of rotavirus related mortality (450,000 deaths), the benchmark by which the impact of rotavirus vaccination programmes were measured.

- #19 Rotavirus – Wikipediahttps://en.wikipedia.org/wiki/Rotavirus
Rotaviruses are the most common cause of diarrhoeal disease among infants and young children. […] Nearly every child in the world is infected with a rotavirus at least once by the age of five. […] Immunity develops with each infection, so subsequent infections are less severe. […] The virus is transmitted by the faecaloral route. […] It infects and damages the cells that line the small intestine and causes gastroenteritis (which is often called „stomach flu” despite having no relation to influenza). […] Although rotavirus was discovered in 1973 by Ruth Bishop and her colleagues by electron micrograph images and accounts for approximately one third of hospitalisations for severe diarrhoea in infants and children, its importance has historically been underestimated within the public health community, particularly in developing countries.

Rotaviruses are the most common cause of diarrhoeal disease among infants and young children. […] Nearly every child in the world is infected with a rotavirus at least once by the age of five. […] Immunity develops with each infection, so subsequent infections are less severe. […] The virus is transmitted by the faecaloral route. […] It infects and damages the cells that line the small intestine and causes gastroenteritis (which is often called „stomach flu” despite having no relation to influenza). […] Although rotavirus was discovered in 1973 by Ruth Bishop and her colleagues by electron micrograph images and accounts for approximately one third of hospitalisations for severe diarrhoea in infants and children, its importance has historically been underestimated within the public health community, particularly in developing countries.

The disease burden of rotavirus is substantial, and the economic burden from infection in infants and children is a threat worldwide. […] Rotavirus vaccination is a cost-effective measure to prevent rotavirus infection. […] The monovalent rotavirus vaccine (a G1P[8] human rotavirus strain) and the pentavalent vaccine exert similar degrees of effectiveness for protecting against infection with homotypic and heterotypic rotavirus strains. […] Expanding rotavirus surveillance networks to industrialized and developing countries as well as implementing persistent rotavirus surveillance are important for identifying newly emergent rotavirus strains and for evaluating the effectiveness of strain-specific vaccine responses in different countries.
