If you own real estate property in a state other than the one in which you live and you have earned money off the rental of that property, you are required to file a nonresident income tax return in that state.
HIV damages the immune system and eventually leads to AIDS. When a person is first infected with HIV it can take up to 3 months for them to develop the antibodies that make an HIV test turn positive. In some rare cases it might take longer, but certainly not ten years. AIDS is not one particular illness but rather a group of opportunistic infections and cancers.
Symptoms of HIV infection won't typically show up immediately. The usual test given to screen for HIV infection won't show anything until about 90 days after the exposure. The reason for this is that a recently infected person's immune system needs time to mount a defense against the virus.
