Portugal at that time suffered from high incidences of maternal deaths and perinatal mortality, reflecting the lack of care available to pregnant women, foetuses and newborns.
Maternity clinics did not have operating rooms nor did they have obstetricians and neonatologists, which meant they were ill-equipped to deal with complications that could arise suddenly.
After the Carnation Revolution of 25 April 1974, when the Estado Novo was overthrown, Araújo was able to carry out training courses on family planning both in Portugal and, between 1978 and 1992, for the United Nations Population Fund in Portuguese-speaking countries, together with Ana Vicente and others.
In her private practice she promoted the ideas of painless childbirth first introduced into Portugal by Cesina Bermudes and Pedro Monjardino.
On International Women's Day in 1998 she was made a Commander of the Order of Merit, a national award given to those making sacrifices of benefit to the community.
