virus was detected in the the blood of stricken children but it has not been found in their diseased livers. According to Centers for Disease Control and Prevention, "laboratory tests identified that some of the children had adenovirus type 41, which is more likely to cause severe stomach illness in children.
Although there have been previous reports of hepatitis in children with suppressed immune systems who were infected with adenovirus, adenovirus type 41 is not a common cause of hepatitis in otherwise healthy children." "Other common causes of viral hepatitis, such as infection with hepatitis A, B, C, D, and E viruses were considered, but evidence for these infections were not found in any of the patients," CDC update has further noted.
Meanwhile, Eric Kremer, a virus researcher at the Institute of Molecular Genetics of Montpellier, in France said, “there's a lot of things that don't make sense." What the health officials are asking about the mysterious illness: What the CDC knows so far: As the illnesses are considered rare, the CDC officials last week said they are now looking into 180 possible cases across the U.S.
Most of the children were hospitalized, at least 15 required liver transplants and six died. More than 20 other countries have reported hundreds more cases in total, though the largest numbers have been in the U.K.
