Document Summary
First you get infected and once you get infected it goes into cells and starts replicating. Consequence of cells- replication, they burst and it kills immune cells (t helper cells) End up with a cd4 cell count that is very low. Less than 200 cells /mm cd4 cell count in aids. Syndrome- entire class of infections that you can get. Epithelial skin cancer your immune system does surveylence of cancer cells. Infection -> cell death -> cd4 -> aids -> your death. In sub saharan africa- co-morbidity factors contributing to this huge increase. Anti retroviral drugs prevents the virus from replicating. Look at graph to compare us and sub-saharan africa. Sub saharan africa - 2. 5 million per year. Saharan africa does not have anti retroviral drugs. Increase in mortality in the course of 1 or 2 weeks. The differences in the death rates have to do with the access to anti retroviral drugs.
