From 1 to 10 April 2020, IOM staff surveyed a total of 67 key informants, who were able to provide informed answers on the situation and COVID-19 related vulnerabilities of different migrant communities and non-Thai populations in Thailand. Results revealed that the most common barrier to COVID-19 specific hygiene and sanitation for non-Thai populations is the cost of personal protective equipment (PPE). Forty-one per cent of key informants reported that the majority of non-Thai nationals do not have daily access to face masks. Respondents reported that the greatest challenge faced by non-Thai nationals since the outbreak of COVID-19 is insufficient income, with 76 per cent of key informants reporting that they have heard of concerns from non-Thai populations about not having enough food to eat. Respondents also reported low awareness levels on COVID-19 symptoms and handwashing practices, with 65 per cent of respondents indicating that lack of literacy is the main reason why non-Thai nationals do not understand COVID-19 related information.
