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.
An example of a type of infection seen a lot in AIDS patients is Pneumocystis jiroveci pneumonia (aka PCP). The way HIV works is that once a person gets infected with the virus, it takes about 4 to 10 weeks before it can be detected in the blood (aka seroconversion). For a small group of people, it may even be more than that. At that time, the person may or may not be experiencing any symptoms.
