Sexually transmitted diseases are those viral, bacterial or parasitic diseases that usually occur due to sexual contact.

These diseases are transmitted by body fluids such as semen, vaginal discharge or blood.

Although most of the STDs transmit through oral, anal or vaginal intercourse, some can be transmitted through skin contact or blood transfusions that are carried in unsafe ways.

The people who are at greater risk of catching an STD are those who have multiple sex partners or their sex partners are involved with multiple other sex partners, those who do not practice safe sex and people who do not use new syringes for intravenous injectable.

In this article, we will discuss some of the most common STDs such as:

  • Acquired immunodeficiency syndrome (AIDS): AIDS is a sexually transmitted disease that is caused by a virus called human immunodeficiency virus (HIV). This virus can be transferred through blood and other sexual fluids and can stay inactive even for years after entering a carrier’s body.

Though, once entered, it cannot be reversed or killed.

The HIV virus causes AIDS only if it enters the stage 3 of infection that usually doesn’t occur due to HIV medicines.

AIDS causes the immune system to deteriorate badly, so that opportunistic infections, infections that attack weak immune systems, occurs creating life threatening conditions.

  • Chlamydia: It is an STD caused by a bacterium called chlamydia trachomatis. It can only be transmitted either through sexual contact with an infected person or through an infected mother to the fetus.

If it gets diagnosed in the earlier stages, it can be cured by antibiotics. Late diagnosis can cause severe damage especially to the infected women.

It can cause pelvic inflammatory disease and can make a woman infertile.

  • Genital herpes: Genital herpes is an STD that is transmitted through herpes simplex virus. This virus can also cause other types of herpes that are not sexually transmitted.

Genital herpes is characterized by itchy, red sores around the genitals or buttocks.

It can cause severe itching and burning sensation on the site of infection.

Herpes simplex virus can infect a person and stay inactive, but still gets transmitted through sexual contact.

The infection can be recurring several times during the year, causing the previous site of infection to give a burning sensation when a new infection occurs.

In women, genital herpes can cause pain while urinating. If left untreated, genital herpes can cause yeast infection.

  • Gonorrhea: It is an STD that is caused by a bacterium called Neisseria gonorrhea. Gonorrhea infects both men and women and it can infect organs such as eyes, male or female genitals, throat and anus.

Gonorrhea causes different symptoms in men and women. In men, frequent urination, a watery, frothy discharge from the penis, swelling of the tip of the penis and a sore throat that doesn’t go away are some of the common symptoms.

The symptoms in women include pain in urination, frequent urination, watery discharge, sore throat and fever.

Even if a patient is asymptomatic, he/she can transmit gonorrhea to their sex partner.
