STD or sexually transmitted diseases spread through vaginal, oral, and anal sex. A few of the bacteria also possess the ability to pass through skin contact, use of contaminated sex toys, by sharing injected drugs, and body piercing.

Although syphilis is curable when detected in the initial stage, if left untreated, it leads to death. Syphilis attacks an individual in stages. The first stage starts with sores. They disappear on their own. The second stage causes rashes and continue to remain for months before subsiding automatically.

The infection then spreads and becomes chronic with no visible effects. In severe circumstances, hepatitis develops to cirrhosis and causes liver cancer.


Chlamydia is the common sexually transmitted disease and goes unnoticed widely when compared with others. As there are no signs of the infection, it develops silently and creates serious complications that lead to death over a period. The disease is widespread in women than men.
