1.10 CD4 differences between adults and children
Children generally have much higher CD4 counts than adults. Babies have higher CD4 counts than children.
- Children under 12 years old with HIV are monitored by CD4% rather than absolute CD4 count.
- After the age of about 60, the adult CD4 count drops gradually.
Table: CD4% and CD4 counts for babies and children
|HIV disease category||CD4%||CD4 0-12 months old||CD4 1-5 years old||CD4 6-12 years old|
|1 – no damage||25% or over||over 1,500||over 1,000||over 500|
|2 – moderate||15-24%||750-1,500||500-1,000||200-500|
|3 – severe||under 15%||under 750||under 500||under 200|
