Document Summary
The virus can be replication in you, but you do not feel the symptons due to suppressant of the immune system (down regulation of the mhci presentation on the host cells) If virus is too strong in these 2 days, may die before adaptive immune comes. If clears virus within 2 days, won"t show any symptoms. Eventually our adaptive response will work after 3 days and by 7 days fully functioning to get rid of the viruses. Advantage: able to remain within the host for a long time, as long as the person lives. Comes and goes, and may not have symptoms when it attacks. Carlos findlay linked yellow fever to mosquito transmission 1881. Jesse lazear test mosquito transmission by exposing herself to mosquito. Discovered how yellow fever was transmitted: mosquitoes transmit yellow fever virus. Patrick laidrow propogated the flu virus into ferrets. Now we grow virus in eggs (chicken embryo at 10 propagates really well)
