ich countries where there it is af<strong>for</strong>dable and there is safe water supply (Horvath, Madi et al.<br />

2009). In situations where breastfeeding does occur the <strong>review</strong> identified exclusive<br />

breastfeeding, and antiretroviral prophylaxis to the breastfeeding infant as preventative<br />

measures <strong>for</strong> the prevention of late postnatal transmission of HIV.<br />

The use of ARV drug prophylaxis in HIV-infected nursing mothers and in HIV-exposed<br />

infants may make breastfeeding a safer option in the developing world, where the benefit of<br />

breastfeeding infants born to HIV-infected women may exceed the risk of transmission.<br />

The Cochrane <strong>review</strong>s summary of evidence on the use of antiretroviral prophylaxis<br />

during breastfeeding<br />

Infant nevirapine prophylaxis <strong>for</strong> six weeks or 14 weeks (among infants of mothers who were<br />

counselled to breastfeed exclusively <strong>for</strong> six months and to consider weaning thereafter) has<br />

shown promise with regard to prevention of MTCT of HIV and <strong>for</strong> improvement<br />

in HIV-free survival. Such infant antiretroviral prophylaxis was well-tolerated. However, the<br />

implications of the studies to date are that antiretroviral prophylaxis to the breastfeeding<br />

infant must continue <strong>for</strong> the duration of breastfeeding (since the efficacy observed with<br />

administration <strong>for</strong> six or 14 weeks dissipates after prophylaxis is discontinued). Nevirapine<br />

resistance among those infants who fail prophylaxis and become infected while receiving<br />

nevirapine warrants further evaluation (Horvath, Madi et al. 2009). In addition to these<br />

finding, the Cochrane <strong>review</strong> that aimed to determine whether, and to what extent,<br />

antiretroviral regimens decreased the risk of mother-to-child transmission of HIV also<br />

concluded that further research is required. The authors stated that it is unclear to what extent<br />

breastfeeding influences the efficacy of antiretroviral treatment as only a few trials in Africa<br />

have been conducted and there results were conflicting (Volmink, Siegfried et al. 2007).<br />

In 2010, the World Health Organization (WHO) revised their previous recommendations <strong>for</strong><br />

HIV-infected mothers. The WHO stated that significant research evidence regarding the use<br />

of ARV interventions has accumulated since their last recommendations in 2006. Evidence<br />

has been reported that ARVs to either the HIV-infected mother or HIV-exposed infant can<br />

significantly reduce the risk of postnatal transmission of HIV through breastfeeding. In the<br />

global context the WHO now recommend that where ARVs are available, mothers known to<br />

be HIV-infected breastfeed until 12 months of age. The WHO encourage national authorities<br />

in each country to decide which infant feeding practice, either breastfeeding with an<br />
