natural history – the pattern a disease follows if it is not treated. The natural history of HIV includes very high viral load in the first weeks or months of infection (seroconversion), a drop in CD4 counts that then recovers, and then a slower progressive increase in viral load and decrease in CD4 count, that eventually lead to opportunistic infections.
