Women, children and other "disadvantaged" groups infected with the deadly AIDS virus sued the federal government Monday, claiming they are being unfairly denied disability benefits.

A class-action lawsuit filed in U.S. District Court contends the Social Security Administration has failed to recognize some disabling ailments that the human immunodeficiency virus or HIV can cause in females, children, drug users and the homeless.The plaintiffs - three women, a homeless man and a 2-year-old child, all from New York - allege they were refused disability benefits despite serious and disabling illnesses resulting from HIV infection. However, the suit is filed on behalf of all people disabled with HIV-related diseases not recognized by the government.
