Which of the following diseases is sexually transmitted?

Correct answer: B. AIDS

  • A. Tuberculosis
  • B. AIDS
  • C. Dengue fever
  • D. Cholera

Explanation

Acquired immunodeficiency syndrome (AIDS) is a chronic, potentially life-threatening condition caused by the human immunodeficiency virus (HIV). By damaging your immune system, HIV interferes with your body's ability to fight infection and disease. You can get HIV from contact with infected blood, semen, or vaginal fluids. Most people get the virus by having unprotected sex with someone who has HIV. Another common way of getting it is by sharing drug needles with someone who is infected with HIV. Hence, Option B is correct.Tuberculosis is caused by bacteria that spread from person to person through microscopic droplets released into the air. This can happen when someone with the untreated, active form of tuberculosis coughs, speaks, sneezes, spits, laughs, or sings. Hence, Option A is incorrect. When a mosquito bites a person infected with a dengue virus, the virus enters the mosquito. Then, when the infected mosquito bites another person, the virus enters that person's bloodstream and causes an infection. Hence, Option C is incorrect. A person can get cholera by drinking water or eating food contaminated with cholera bacteria. In an epidemic, the source of the contamination is usually the feces of an infected person that contaminates water or food. Hence, Option D is incorrect.

About Acellular Life

Viruses are acellular infectious particles whose capsid, nucleic acid and host-dependent replication distinguish them from living cells. HIV infection covers transmission, replication, effects on helper T cells, progression to AIDS, symptoms, prevention and treatment, while AIDS is the disease state caused by advanced immune-system damage rather than a separate virus.
