However, doctors are also reporting an increase in patients with acute respiratory symptoms of another viral infection. According to ICMR, it is caused due to influenza A subtype H3N2.

#Adenovirus in Children: Recent surge
Adenovirus causes mild infections mostly in children
Outbreaks of ‘Madras eye/pink eye’, clusters of seasonal respiratory illness are not unusual
Severe illness with adenovirus has been rare
After a build up over 3mo we now see a surge

Parents should look out for:
Sudden onset high fever with chills
Headache and throat pain
Nausea and vomiting
Red eyes and red throat
Poor response to fever medications
Excessive tiredness
Burning sensation during urination

This infection is more of an inconvenience than a cause of concern
As a rule, kids get better in 5-6 days, very few need short hospitalisation to stay hydrated
Severe and unusual presentations needing ICU care (pneumonia or multi-organ involvement) are exceptionally rare

Il paraît que ce post a énervé beaucoup de gens réveillés? Je ne fais qu'analyser et expliquer des études scientifiques, comme depuis 2 ans. Et j'ai encore 2-3 arguments pour en finir avec la théorie de Lanka ou Kaufman que les #virus n'existeraient pas.⏬
Les détracteurs de #virus disent qu'ils "sont confondus avec des #exosomes. Faux & facile à prouver.
Les exosomes, produits par nos cellules, jouent un rôle de messagers. Ils ont une forme sphérique et peuvent #ressembler au virus.

Researchers found high adeno-associated virus 2 (AAV2) levels in the blood or liver cells in 24 of 25 children with unexplained hepatitis.
In a group of kids without this condition, almost none had AAV2, even those with #adenovirus.

1. Interesting update on #PediatricHepatitis from @ECDC_EU + @WHO_Europe. It contains the first epicurve I've seen, which is very helpful because reported cases include current & previous cases found through record searches. The 1st case here dates to Sept 2021.
2. A large majority of the European #PediatricHepatitis cases are really young — 76% under the age of 5.
3. The @ECDC_EU/@WHO_Europe #PediatricHepatitis update says as of May 13, a total of 232 cases have been reported. Puzzled by the UK number (131) because yesterday @UKHSA reported 176 cases.
This report reports 3 epidemiologically linked cases, which is interesting.
This report reports 3 epidemiologically linked cases, which is interesting.
1. @WHO held a press briefing today. Some interesting but disparate points made at it.
Pediatric #hepatitis: To date 348 probable cases from 5 regions of the world have met the case definition; 70 more are being studied. Only 6 countries have reported more than five cases.
Pediatric #hepatitis: To date 348 probable cases from 5 regions of the world have met the case definition; 70 more are being studied. Only 6 countries have reported more than five cases.
2. Of the pediatric #hepatitis cases, 70% have tested positive for adenovirus, mostly type 41. ~18% of the cases tested positive for #Covid19. @WHO's Philippa Easterbrook says while adenovirus is still the chief suspect, prior or current Covid as a cofactor is still in the mix.
3. @WHO's Easterbrook says "within the week" there should be data from a UK case control study comparing adenovirus rates between kids with hepatitis of unknown etiology and other hospitalized children. Will help to see if #adenovirus is an incidental finding, she said.
Unknown #Hepatitis in #children: From my point of view as a clinical virologist, there are many aspects that speak against #Adenovirus, with important implications for treatment. Why? Viral loads in the cases reported to be low. Normally viruses causing hepatitis are massively
found in the blood. Hepatitis virus A, B, E, when causing fulminant clinical hepatitis: very high viral loads (C rarely causes this). Same for other viruses with hepatic tropism (eg Yellow fever). Viral hepatitis with pronounced clinical picture but low viral loads doesn’t exist
Now in the children with hepatitis no Adenovirus was detected in the liver biopsies, and viral load in blood was low. In some cases, Adenovirus DNA only in whole blood but not plasma. Again: a virus that is replicating in liver should be found everywhere: plasma, serum, biopsy
🚨 New study, relevant to 'mystery' child #Hepatitis.
🚨69% autopsied livers SARS-COV-2 RNA +
🚨Proteomic- etc profiles show "similarities to signatures assoc with multiple other viral infections of human liver" BUT was shown to be covid inf of hep cells

Evidence of DIRECT SARS-COV-2 infection of hepatic cells ➡️ interferon spike ➡️ hepatitis. Paper clearly states it may look like another virus but investigation proves IT IS NOT. It's SARS-COV-2.
Can we call this duck a duck now?

111 cas d'#hépatite chez des moins de 16 ans, depuis janvier 2022, un début de maladie ressemblant à une gastro avec jaunisse. Pas de décès UK, beaucoup de moins de 5 ans, 40 cas d'adénovirus sur 53 cas testés.

Unklare #Hepatitis-Fälle bei #Kindern - eine Einordnung meinerseits. Seit einigen Wochen werden vermehrt Hepatitis-Fälle bei Kindern unter 10 Jahren (Gipfel 2-5) gemeldet, bislang aus UK, Dänemark, Niederlande, Spanien, Israel und nun auch USA, mit Beginn wohl schon in 2021
Aktuelle Daten findet man hier (ECDC) ecdc.europa.eu/en/news-events… und auch hier promedmail.org (PromedMail), bei letzterem allerdings auch ungeprüfte Quellen. Vorläufige Falldefinition & erste Publikation aus Schottland hier: eurosurveillance.org/content/10.280…
Vorab sei gesagt, dass es noch sehr früh ist & man wirklich noch nichts genaues weiß. Es ist im Moment wichtig, nicht zu schnelle/voreilige Schlüsse zu ziehen. Man kann auch alle nur darum bitten, Thema nicht für eigene Agenda zu missbrauchen & Fehlinformationen zu verbreiten.
Mix It Up:
💉You can freely select between Pfizer & Moderna for your 3rd dose, regardless of which one you used for the 1st and 2nd doses
💉I expect J&J (adenovirus) will suggest a booster
💉I predict you will be allowed to switch (from adenovirus) to mRNA for the booster dose

💉The AstraZeneca adenovirus vaccine was used in this study

mRNA:
💉Moderna had more side effects (9.7% fatigue) than Pfizer (3.8% fatigue) in 1st/2nd doses
💉I predict Moderna 3rd dose will be a half-dose of 1st/2nd doses (less side effects)
💉Moderna protection from 1st/2nd doses isn’t waning as fast as Pfizer

Dr Robert Malone - Q: Why do you call the #adenovirus-based (J&J) and #mRNA-based #vaccines #gene therapy-based vaccines? And why is that important? Are you just trying to scare people? Are you an #antivaxxer? linkedin.com/feed/update/ur…
why gene therapy-vaccines? both types of vaccines employ technologies that involve transfering foreign genetic material into the cells of the person receiving the vaccine, making those cells essentially become miniature vaccine antigen manufacturing factories - inside the body👉
for vaccination, the "active drug substance" is not the gene therapy vector, it is the protein that is manufactured in your cells.from an FDA/regulatory point of view, these products need to be reviewed using the regulations applied to "gene therapy" products ... 👉

¿Qué es un vector viral?
Un vector viral es un virus inofensivo que puede transportar un gen extraño a nuestras células para que estas produzcan una determinada proteína. Los científicos han estudiado el uso de vectores virales para terapia génica y vacunas.

Unfortunately, removal of process-related #impurities from viral vector-based #therapeutics (e.g. host-cell proteins) is imperfect and low levels - orders of magnitude lower than the actual active therapeutic - are usually accepted if they are classified as non-problematic

At least 7 teams are developing #SARSCoV2 #vaccines using a weakened / inactivated virus. Several existing vaccines are made this way, i.e. #measles & #polio #vaccine. Sinovac Biotech started to test an inactivated SARS-CoV-2 #COVID19 vaccine. #scicomm
At least 25 groups are working on viral-vector #SARSCoV2 #COVID19 #vaccines. A #virus such as #measles or #adenovirus is genetically engineered so it can produce #coronavirus #proteins in the body. These #viruses are weakened so they CANNOT cause disease.
