Contagious Diseases: Understanding Transmission of HIV, HPV, Cancer, Diabetes & Hypertension

AIDS and warts can be caught from another person.

AIDS is caused by the human immunodeficiency virus (HIV), which can be transmitted through contact with infected blood, semen, or vaginal fluids. Warts are caused by the human papillomavirus (HPV), which can be transmitted through skin-to-skin contact.

Cancer, diabetes, and hypertension are not contagious diseases. They are caused by a variety of factors, including genetics, environment, and lifestyle choices.
