That totals This preventative measure is highly popular since the South African government progressed the ART program since the early s. South Africans have invested themselves in taking advantage of the free testing. A guaranteed treatment for those testing positive increases the number of South Africans willing to obtain testing. ART treatment offers an avenue to health for many infected individuals. It prevents further spread, curbs symptoms and can make healthy populations resistant to the virus.
Blog - Latest News. Because the apical domain is not involved in the critical task of moving iron into cells, Harrison says it presents an attractive target for drugs. In theory, an antibody designed to attach to the apical domain would prevent the Machupo virus from attaching to cells, blocking infection. One possible treatment strategy, then, would be to infuse patients with such an antibody during the early stages of infection, which might slow the infection enough to let patients recover.
Harrison says the finding might also help virologists predict which of the 22 known arenaviruses might be capable of infecting humans. Only five are known to infect humans now -- and all of those bind to the human transferrin receptor. Presumably the other 17 viruses produce surface proteins that are unable to bind to the human transferrin receptor, Harrison says.
For Abraham, the idea of finding a treatment for these New World hemorrhagic fevers is close to his heart. His family hails from Haiti, where there is a "huge burden of infectious diseases.
