When transgender women in Queens needed a safe place to be tested for H.I.V., Lorena Borjas turned her home into a clinic. When others were arrested and charged with prostitution, she bailed them out. When some faced deportation after an arrest, she created a nonprofit group to arrange for their legal representation.

Ms. Borjas, an indefatigable activist who drew on her own experiences as an immigrant transgender woman to help others, died on Monday at a hospital in Brooklyn. She was 59.

Chase Strangio, a friend and colleague, said the cause was complications of the coronavirus.

Ms. Borjas became a guardian angel of sorts for the transgender community in Queens, helping women deal with sex trafficking, police harassment, substance abuse and health problems.
