Table 4: Events of infectious illness in HIV-exposed uninfected (HIV-EU) infants compared to term HIV-unexposed infants, according to their different feeding modes at 4 months of age. The observation period between each examination was 4 months. is the mean number of cumulated infectious events between two evaluations per child in every feeding mode category.

Mean number (min–max) of cumulated infectious events

Time of examination:

Feeding mode and cohort:
 HIV-EU: human donor milk1.8 (0–8)1.7 (0–4)*3.2 (0–7)*
 HIV-unexposed infants: exclusively breastfed until 4 months of age2.0 (0–4)5.7 (1–13)**9.0 (5–20)
 HIV-unexposed infants: exclusively formula-fed until 4 months of age2.5 (1–5)12.5 (2–35)9.5 (3–15)
 HIV-unexposed infants: partially breastfed until 4 months of age1.8 (1–3)8.2 (1–26)7.9 (4–13)

HIV-EU infants had significantly less infectious events than the other infants.
Infants exclusively breastfed until 4 months of age had significantly fewer infections at 8 months of age, than the exclusively formula-fed infants.
