Coronavirus was able to penetrate him like HIV and hepatitis.
In the article, Australian researchers described the discovery of coronavirus infection in the milk of nursing mothers. At the moment it is the only such case, which said the scientists. Russian experts confirm this possibility, however, believe that the benefits of breastfeeding outweigh the risks associated with having breast milk in SARS-CoV-2.
Scientists Australian medical center Flinders, where the open test clinic COVID-19, recorded the first case of detection in breast milk coronavirus RNA.
this time her baby was eight months old and the mother fed him three times a day. When the woman, after tests PCR, was diagnosed COVID-19, she immediately stopped giving the breast to the baby. At this point, the first analysis of mother’s milk, which confirmed the presence of coronavirus.
ten days later the test was repeated and again found in the milk of RNA pathogen. The child, as it turned out, also was infected initially, but the symptoms of the disease he had.
Australian scientists not only established the first presence of coronavirus in breast milk, but indicated the longest period of its selection from the feces of a child. They claim that the virus was in its analyses for 66 days.
Scientists emphasize that the mechanism by which coronavirus has penetrated into the breast tissue remains unknown.
the Researchers in this case, I draw attention to the fact that milk can contain antibodies to coronavirus, although in this case they are, this fact is not checked. However, in the literature there is an article of scientists from the Center for control and prevention of diseases in Atlanta (USA) about the first SARS virus (which caused SARS in 2002-2003. — “News”), antibodies to which were found in breast milk.
Russian experts confirmed the possibility of finding the coronavirus in breast milk. But stressed that this is not evidence of vertical transmission of the pathogen.
— While the answer to the question about the risk of transmission of coronavirus in mother’s milk no, — said “Izvestia” head of the laboratory of biotechnology and Virology of the Novosibirsk state University, corresponding member RAS Sergey Netesov. — As there is no certainty that there is vertical transmission from mother to child or fetus. But this possibility cannot be ruled out. Such cases are known in HIV infection viruses of hepatitis b and C, and several others.
But even as HIV-positive mothers fed their babies for a long time, the virus is transmitted not to all the babies, said “Lime��m” Deputy head of laboratory of the analysis of indicators of population health and the digitization of health MIPT (University —participant of the competitiveness enhancement program of education “5-100”) Stanislav Otstavnov.
— On the who website stated that the two-year breastfeeding HIV-positive mother, not receiving antiretroviral therapy, leading to infection only each the fifth-seventh child, — said the expert. — The rejection of breastfeeding in resource-limited settings (the focus of this research was to Africa) led to significantly worse — as a result of deficit of diet and diarrhea kids just died.
And this is not surprising, since SARS-CoV-2 specializiruetsya exactly on respiratory spread is the most effective and fast way, said the head of the laboratory of genomic engineering MIPT Pavel Volchkov.
— Usually, the virus tries to use all possible ways to distribute, penetrating into all body fluids. There are viruses that spetsializiruyutsya it is at the penetration through the milk, but SARS-CoV-2 is not one of them. However, as it infects different organs, it is not surprising that the pathogen is found in breast milk, he said.
According to him, the “strategy” of coronavirus are very clear. As the most rapid route of entry respiratory, evolution should be towards the selection of such specialized delivery options SARS-CoV-2 in the human body. Now, if the coronavirus could not spread airborne by and the milk would be the only way of transferring strain, the evolutionary pressure would be manifested in that direction.
it is absolutely all experts are convinced that the benefits of breastfeeding outweigh the risks associated with breast milk infection with the novel coronavirus.
