E/CN.4/2001/83 page 26 in all circumstances, and in order to combat organized crime, refrain from claiming that all nationals of particular countries or regions have the same patterns of behaviour. Undocumented women and children 117. Governments are urged to promote and strengthen regional intergovernmental entities composed of civil society and academic institutions to study, draw attention to and agree on the topic of migration, including the human rights of migrants from the gender perspective, with particular emphasis on the situation of migrant women and children. The action of forums and intersectoral round tables (Governments, NGOs, churches, universities and migrant organizations) should be stepped up in order to debate, recommend and find solutions to the migration problem and, in particular, the full and effective protection of the human rights of migrants. 118. States must guarantee access to health services for migrants, especially migrant children. The Special Rapporteur encourages States which have adopted legislative measures to offer such access to study the effectiveness of the measures adopted and find ways to make them more effective. She commends States which are implementing the right to health for migrants who are undocumented or in an irregular situation. Migrants in detention 119. All Governments are urged to increase human rights training for immigration officials, the police and bodies that prevent violations of human rights. Officials dealing with migrants who are in detention or who have been subjected to trafficking or degrading work because they have no documentation must receive special training relating to the situation of these persons. Codes of conduct must be drafted so that professional attention may be given to this problem. Return of migrants to their country of origin 120. The Special Rapporteur encourages States to promote public policies responsibly to inform its nationals about the risk involved in undocumented immigration. She also urges countries of origin to collaborate with host countries to provide their nationals with valid travel documents for a dignified return. 121. The question of the return to their country of origin of migrants who do not have documents is provided for in the Special Rapporteur’s mandate. It is very important to formulate policies and accompaniment programmes for dignified returns within humanly acceptable time limits because any continued detention, uncertainty or clandestinity has physical and psychological consequences which are prejudicial to the fundamental rights of migrants. 122. The Special Rapporteur urges States to work together with organs of civil society on the human rights situation in detention centres. Links between States and NGOs must be strengthened with a view to assistance for migrants in detention centres. Such assistance must apply not only to physical health, but also to the mental health of detainees and their links with their country of origin, family and consulate. _____
