The continuing migration process of migrants from Burma to Thailand over the two decades has given many implications to the Thai society, and one of these implications is the impact on public health. This study aims to investigate the health situation of the second generation of migrants from Burma who migrated to Thailand with their fathers and/or mothers, or were born in Thailand. Moreover, this study aims to analyse the accessibility to public health services, including problems and limitations in the access to public health services of these population group. Areas in the 4 provinces had been selected. These provinces are Chiang Mai, Tak, Samutsakorn and Ranong. Interviews with the second generation group of 80 people and in-depth interviews with 30 staffs from 24 involved government and non-government organizations were done. It was found that most of the second generation had some common illnesses such as headache, stomachache and fever, and would prefer to buy medicine by themselves. If the symptoms persisted, they would go to the health stations, clinics, or hospitals. Factors affecting the decisions of where to go for treatment are diverse and varied between each area. In every studied area, if was found that foreign migrant public health volunteers and foreign migrant public health staffs play an important roles in the accessibility of the second generation group, including in community health support and knowledge, consultation, and co-operation with staffs from organizations as well as translation. Moreover, this study found that public health access in child and maternity health were mostly found among the second generation group. Because this group is in their reproductive years which involving pregnancy check-up, birth deliveries, and basic vaccine treatments for small children. However, the unfound severe infectious diseases in the sampling population do not mean that these people are not at any risk. In reality, this second generation group live and work in the same community as other foreign migrants (particularly the first generation who have just migrated into the country), and sometimes including the Thai labourers. This means that they are at a higher risk in getting the infection as well as being the infectious carriers to other people. Therefore, it can be seen that health and disease problems are not a problem of any one particular group. If it had spread, it would, unavoidably, have affected the whole society. In addition, problems found in statuses and rights of this second generation group reflect problems related to health care planning that the Thai state can no longer ignored. These include: foreign population information database system – including health information which is very important and useful for planning in dealing with health situation, and can be linked with other sectors. Or the need to clearly and appropriately differentiate health services between human and citizen rights. Study results in problems and limitations in government organization health services show that the government hospitals in border areas or areas with a high number of foreign migrants have several heavy burdens. These include the increasing expenditure, lack of staffs, medicine and medical supplies, problems in communication as well as budget management that does not consider and cover the real number of foreign migrant population. All of these problems indicate the urgent need for the state to seriously consider the foreign migrant problems, and should have policies and regulations that are clear, appropriate, and harmonious for every sector involved.
