Victoria Beckham has been on a visit to Cape Town to support the Born Free campaign.
The fashion designer, 39, is hoping to highlight the work of Born Free, which campaigns to end the transmission of HIV from mothers to their children.
A representative for Victoria told MailOnline: "It was a whirlwind trip, however Victoria was inspired and motivated by the wonderful people she met and will continue her support to help raise awareness of the objective to end mother to child transmission of HIV."
MailOnline reports that the former singer visited the Children's Infectious Disease Clinical Research Unit and later thanked, on Twitter, the "inspiring" doctors, mothers and children that she met there.
The mother-of-four also visited the Desmond Tutu HIV Foundation in Cape Town and spent time at Tygerberg hospital.
The website quoted Dr Mitch Besser, founder of Mothers2mothers and the husband of HIV and Aids activist Annie Lennox, as saying: " We are at the cusp of seeing the dream of an HIV-free generation become a reality and need dedicated and compassionate people like Victoria Beckham to spread the word.
"[We need] to make sure the resources and political will continues to be strong, to speak out on behalf of the women and children whose voices often go unheard and to make sure every baby has a chance for a healthy future."
