The COVID-19 pandemic had a devastating impact on the health and wellbeing of populations around the world, with vulnerable groups, including sex workers, being disproportionately affected. This study explored the effects of COVID-19 lockdown restrictions on the lives of female sex workers in Pattaya, Thailand. In-depth interviews with ten women were used to explore the ways in which they sought to cope during the crisis using Lazarus and Folkman’s transactional model of stress and coping. Findings suggest that those who could, tended to seek economic shelter with their parents in rural parts of the country during the pandemic. However, those who could not relocate to be with family were forced to try to eke out a living in other ways, which could be both challenging and dangerous. None reported receiving any financial support from national or local authorities, to whom they were invisible, and this placed tremendous pressure on both them and their families. The authors conclude that the pandemic further highlights the need for the Thai Government to accept the reality of sex work and seek to both legitimise and protect vulnerable women and their labour.
