The U.S. Centers for Disease Control and Prevention (CDC)
classify HIV infection into 3 stages:1
The World Health Organization (WHO) classifies HIV infection into 4 stages:1
In general, the higher the CD4+ count, the less likely it
opportunistic diseases will occur. Most people who
have untreated HIV experience a gradual drop in the number of CD4+ cells. Each
person responds uniquely to this decline.
