The number of reported cases is increasing around the world. The World Health Organization is continuing its investigations, but the strongest hypothesis is that of an adenovirus.
- These acute hepatitis of unknown origin affect children.
- 20 countries in the world are concerned.
- Adenovirus 41 is implicated in gastroenteritis.
Research is continuing to understand the origin of this acute hepatitis that affects children. Tuesday, May 10, Dr. Philippa Easterbrook, scientist, member of the hepatitis research department of the World Health Organization (WHO) gave an update during a press conference. So far, the organization has identified 348 cases in five regions of the world. 70 suspected cases are under investigation.
How is the number of cases changing?
According to WHO data, six countries have more than five cases, but the UK is by far the most affected: More than 160 children have been diagnosed there. In early May, five deaths were recorded in the United States. In Indonesia, three children died of this pathology. In France, health authorities have confirmed two cases.
What are the symptoms ?
Affected children suffer from gastrointestinal symptoms, sometimes jaundice. Some of them had liver failure, and had to receive a liver transplant. In a study of 109 cases in the United States, researchers found that the median age of affected children was two years old. In 90% of cases, their illness led to hospitalization.
What are the possible explanations?
“At this time, the main hypotheses remain those involving adenovirus, also taking into important consideration the role of Covid, either as a co-infection or as a prior infection”says Dr. Philippa Easterbrook in an interview with GlobalNews. The adenovirus was one of the first avenues considered by the scientific community. Until now, this type of virus was mainly associated with respiratory and digestive disorders or conjunctivitis. The latest tests carried out by the WHO indicate the presence of an adenovirus in 70% of cases. On the other hand, subtype 41 was the most common variant.
Covid-19 is also monitored by the scientific community: in other tests, researchers found that 18% of sick children tested positive for SARS-CoV-2. “Next week we will focus on serological testing for previous exposures and infections to Covid-19.”says Dr. Philippa Easterbrook.
