HIV care and treatment has come a long way in the past decade, write Brian Honermann and Mark Heywood in this opinion piece marking 10 years since South Africa's Constitutional Court upheld the constitutional right of all HIV positive pregnant women to access health care services to prevent mother to child transmission of HIV (PMTCT). 'In 2002, an HIV positive mother would pass on HIV to her baby about 30% of the time. With access to Nevirapine the transmission rate was cut in half. Now, with better drug regimens being used, transmission of HIV from mothers to babies happens in only about 4% of cases during or shortly after birth.'
