Introducing ARVs into antenatal and postnatal care significantly improves the chance that babies of HIV-positive mothers can be born without the virus. “I am a happy mother,” says Susan Simfukwe in Lusaka. “I think the American government has really helped us Zambians. If it wasn’t for them, I don’t think we’d have ARVs now. I want to thank the American people as their support has really served us.” Since 2007 the Zambian ARV logistics system has given more than 165,000 women like Susan access to PMTCT drugs.
