This work aims to characterise the day-to-day management of public health policy targeting migrant women from rural areas of Bolivia in a city of Patagonia, Argentina. The fieldwork was carried out between 2016 and 2018 in two primary health care centres, located in peri-urban neighbourhoods in the city of Comodoro Rivadavia, by accompanying daily health effects, meetings, talks and interviews with professionals, officials and migrant women. There is evidence of a targeted and mentoring policy with regard to the health of migrants, which ensures a generalised, ethnicised, social class and generational reading, underpinning control and subjective techniques, which in some cases are contested. From an ethnographic approach, contributions from anthropology of health, the state and an intersectional gender perspective account for the production and management of risk, as well as its tensions in contexts of inequality.
