Table 4 Simulated scenarios of MTCT rates of HIV in prevalent maternal population according to the fixed coverage of PMTCT services in Cameroon in 2011

From: Estimating mother-to-child HIV transmission rates in Cameroon in 2011: a computer simulation approach

100 % of PMTCT services coverage
MTCT circumstances Estimated number of incident paediatric infections [95 % Confidence Interval] Estimated transmission rate (%)
Perinatal rate (<6 weeks of age) 165 [99–398] 0.4 [0.2–1.1]
Postnatal rate (>6 weeks of age to 24 months) 149 [99–298] 0.8 [0.5–1.6]
Total 316 [198–631] 0.9 [0.5–1.7]
90 % of PMTCT services coverage
Perinatal rate (<6 weeks of age) 509 [199–995] 1.4 [0.5–2.8]
Postnatal rate (>6 weeks of age to 24 months) 205 [99–497] 1.3 [0.5–3.0]
Total 711 [306–1, 187] 2.0 [0.9–3.2]
