A variety of social factors have perpetuated the spread and worsened the severity of HIV/AIDS in the Caribbean. Many persons are at increased risk of HIV infection because of their social vulnerability, arising from poverty, illiteracy or limited education, unemployment, gender inequity, and sexual orientation. HIV/AIDS can weaken the national education system, perpetuating the spread of the disease by hindering efforts to educate the public about the disease. Furthermore, a weak political response by the government can result in ineffective programs. Public policies in some countries openly discriminate against HIV-positive people, placing the burden of responsibility on the family of the infected individual. Discrimination also takes place in housing, employment, and public accommodations, and currently little is able to be done. Because of these factors, many have less knowledge, skills, and motivation to practice safe-sex and avoid the disease.
