Very rare cancer cases, neurological complications, and drastic malnutrition are the general symptoms of AIDS. Further, acquiring AIDS leads to more harmful diseases like common bacterial infections (Toxoplasmosis, Progressive multifocal leukoencephalopathy, Escherichia coli, Listeria, Campylobacter, Salmonella, and Shigella), Kaposi's sarcoma (cancer of the blood vessel), Pneumocystis jiroveci pneumonia (caused by yeast-like fungal infection), and dementia complex.

The ways through which humans can have an HIV infection are the same as the way they can get AIDS. Among the most common modes of transmission are unprotected sexual contact (vaginal, oral, and anal contacts) with an HIV-infected person, blood or blood product route, and pregnant women instances or mother-to-child transmission. The means to avoid being infected also go the same for both HIV and AIDS. To avoid infection through sexual contact, abstinence or the use of condom, to avoid exposure to infected bodily fluids, are most advised by many doctors. On the other hand, needles should never be shared to prevent HIV or AIDS transmission through blood product routes.

It is good for people to know that HIV or AIDS is not an airborne disease nor is it transmissible by mere physical contact to avoid *paranoia cases* and unfounded judgments towards others. Currently, HIV is a disease that can be treated but not cured. Anti-retroviral agents, which are not accessible to most people with HIV, can only go as far as reducing the complications but cannot totally eradicate the presence of HIV. As of now, no vaccine has yet been developed to prevent the transmission of HIV, more so the deadly existence of AIDS.
