Out of the following, which one is not a probable cause of spreading AIDS?

HIV AIDS is caused by a virus and not by any bacteria.

Important Points

• Blood, breast milk, semen, and vaginal secretions are just a few of the bodily fluids from infected people that can spread HIV. During pregnancy and delivery, a mother's HIV infection might pass to her kid.
• Normal daily interactions like kissing, hugging, shaking hands, or sharing personal items, food, or water do not cause an infection in a person.
• Having condom-free anal or vaginal sex, having a STI like syphilis, herpes, chlamydia, gonorrhoea, or bacterial vaginosis, using harmful alcohol and drug combinations during sexual activity, sharing contaminated needles, syringes, and other injecting equipment and drug solutions when injecting drugs, and receiving unsafe injectable drugs are all behaviours and medical conditions that increase a person's risk of contracting HIV AIDS

Thus we know that bacteria cannot be a probable cause of spreading AIDS.
