Vadim Pokrovsky, head of the scientific center for the prevention and control of AIDS of the Rospotrebnadzor Central Research Institute of Epidemiology, said that the viral nature is the main hypothesis for the origin of acute hepatitis of unknown etiology, which was detected in several children. countries. This has been reported TASS.
According to Pokrovsky, researchers are looking for a previously unknown virus or a new version of a previously known virus. Among the suspects is a variant of adenovirus, usually detected in the UK.
According to him, the viral nature of this hepatitis is the main hypothesis, although the usual pathogens of hepatitis in children were not found. The scientist also said that the possibility of autoimmune hepatitis is unlikely, even in a few dozen children.
He also noted that toxic hepatitis is possible, but unlikely to develop in children from different cities and countries due to a common toxic substance. The expert suggested that a combination of a previously known infection and a common toxic factor could be the cause of unknown hepatitis.
He added that the published research data is not yet sufficient to make connections between patients and that new results are awaited.
More than a dozen countries have previously reported about 200 cases of childhood hepatitis of unknown cause. About half of the cases in children were isolated adenovirus F41, which causes vomiting and diarrhea, although it is not yet clear whether it is the cause of hepatitis.
How declaration According to Pavel Volchkov, head of the MIPT Genomic Engineering Laboratory, cases of unexplained hepatitis in children can be caused by a virus, but to speak of an epidemic, you must first identify patient zero.
