Setembro Amarelo is Brazil's national suicide prevention campaign, held every September, a month that includes World Suicide Prevention Day on September 10. The yellow ribbon and colour became its recognisable symbol as schools, health workers and creators began sharing talks and messages throughout the month. This clip circulates online under Raquel Brito's name, tagged as an official recording, and is shared in Portuguese-speaking spaces during September. It remains in use because the short spoken format makes an awareness message easy to forward at the exact time of year people are looking for it.
