In Soyapango, a city neighbouring San Salvador, MSF operates an ambulance service in conjunction with an existing service run by Comandos de Salvamento. In recent years neighbourhoods and communities within the city - home to around 250,000 people - have become bastions of gangs and violence, and difficult to access by medical services. In El Salvador, they are defined as "red zones". In Soyapango MSF has two ambulances (one medicalised) for the transport of patients which, in emergencies, enable people living red zones to access health centers and hospitals. An innovative element of this service is that MSF has introduced women into the combined role of nurses and - something more unusual in El Salvador - drivers. In this video, Claudia Ramírez talks about her daily routine and motivations as a nurse and driver.
