The use of early and intense treatment is actually a paradigm change in HIV/AIDS treatment in kids in the developing globe, where mothers are typically treated during pregnancy to lower the risk of moving the virus to the child. In those circumstances you do not aggressively treat the baby. You wait around about six weeks [after birth] until you can definitively demonstrate that the infant is infected and then you treat them. Sadly, if the baby is infected, after that that may have given the virus a period of time to establish itself. Fauci described that the Mississippi case may lead to a change treatment plans and added that, we will have to start looking at the relative risk versus the advantage of doing it in this manner.Damaging the immune responseAn earlier study, conducted by researchers from Marine Biological Dartmouth and Laboratory Medical School and released in Environmental Health Perspectives in 2009 2009, found that mice subjected to 100 ppb of arsenic for five weeks later had an extremely weak initial response to infections with the H1N1 flu strain. When a regular person or mouse can be infected with the flu, they immediately develop an immune response in which immune cells rush to the lungs and produce chemicals that help battle the illness, researcher Joshua Hamilton said. Notably, the exposed animals did experience a strong response several days afterwards disproportionately, when it had been too late to accomplish any good.
