Various NGOs highlighted the vulnerable situation of women working as caregivers and domestic workers, which often leads to abusive working conditions, including long working days for little pay without social security. Additionally, it has been highlighted that migrant women constitute the highest percentage of those engaged in prostitution and the sex industry, reaching 90 per cent of street prostitutes in some cities.34 A study by the Parsec Consortium indicates that there are about 17,500-22,700 foreign women in the street prostitution sector, the majority of them from Eastern Europe (41 per cent) and Africa (33 per cent) followed by Latin America (19 per cent), ex-Soviet countries (5.8 per cent), Asia (0.2 per cent) and others (0.8 per cent).35 Around 7 per cent of them (1,292-1,629)36 are said to be minors and a minimum number of 11,920 and a maximum of 15,425 are said to be women migrants engaged in indoor, as opposed to street prostitution.37 The study estimates that a minimum of 2,508 and a maximum of 3,209 women were trafficked during 2004-2005. Official data for 2003-2004 indicate that there were 1,971 victims.38 52. As an indicator of the health situation of migrants, it was explained that for three years civil society has been running a project providing medical care in the Puglia region to remedy the lack of assistance and unsanitary conditions. In May 2006 a refugee-like camp was established in Cassibile to house and provide basic humanitarian assistance to about 400 migrants working in the fields in that area. Among the seasonal farm workers in southern Italy, a survey conducted by Medici senza frontiere found that 30 per cent of the workers had become ill during their first six months in Italy, and after 19 months in the country, 93 per cent of the people surveyed needed to see a doctor. Infectious diseases, skin problems, intestinal parasites, and mouth, throat and respiratory infections (including tuberculosis) were widespread. The most severe illnesses were found among those immigrants who had lived in Italy the longest (18-24 months). 34 See Study on National Legislation on Prostitution and the Trafficking in Women and Children, Trafficking in Persons and Smuggling of Migrants into Italy, Ministry of Education and Ministry for Equal Opportunities, p. 90. 35 See Parsec Consortium Study, Sintesi del Rapporto Finale del Progetto per una Recerca-azione su “Prostituzione straniera e traffico di donne a scopo di sfruttamento sessuale.
