AIDS is caused by the Human Immunodeficiency Virus (HIV) and is transmitted by sexual contact, blood-to-blood contact (blood transfusion) with an infected person where the body fluids are getting exchanged with the non-infected person.

Cholera is caused by the bacterium Vibrio Cholerae and is transmitted by ingesting contaminated water or food.

Malaria is caused by the protozoan microbes called Plasmodium vivax and transmitted by female Anopheles Mosquitoes.
