What You Should Know About STDs

Home » What You Should Know About STDs

Sexually transmitted diseases (STDs) are infections that pass from one person to another through sexual contact.

They are also known as sexually transmitted infections (STIs) or venereal diseases (VD).

Some STDs can spread through the use of unsterilized drug needles, from mother to infant during childbirth or breast-feeding, and blood transfusions.

The genital areas are generally moist and warm environments, ideal for the growth of yeasts, viruses, and bacteria.

People can transmit microorganisms that inhabit the skin or mucous membranes of the genitals. Infectious organisms can also move between people in semen, vaginal secretions, or blood during sexual intercourse.

Individuals pass on STDs more easily when they are not using contraceptive devices, such as condoms, dams, and sanitizing sex toys.

Some infections can transmit through sexual contact but are not classed as STDs. For example, meningitis can be passed on during sexual contact, but people can acquire a meningitis infection for other reasons. It is therefore not classed as an STD.

The World Health Organization (WHO) estimates that there are more than 1 million new STDs acquired each day globally.

People between the ages of 15 and 24 years acquire half of all new STDs, and 1 in 4 sexually active adolescent females has an STD. However, STD rates among seniors are increasing.

The following sections explain the most common STD’s.

Chlamydia

is an STD caused by Chlamydia trachomatis (C. trachomatis). This bacterium only infects humans. Chlamydia is the most common infectious cause of genital and eye diseases globally. It is also the most common bacterial STD.

According to the Centers for Disease Control and Prevention (CDC), in 2015, nearly 3 percent of girls aged 15 to 19 years had chlamydia.

Women with chlamydia do not usually show symptoms. Any symptoms are usually non-specific and may include:

  • bladder infection
  • a change in vaginal discharge
  • mild lower abdominal pain

If a person does not receive treatment for chlamydia, it may lead to the following symptoms:

  • pelvic pain
  • painful sexual intercourse, either intermittently or every time
  • bleeding between periods

Chancroid

Chancroid is also known as soft chancre and ulcus molle. It is a bacterial infection caused by called streptobacillus Haemophilus ducreyi. The infection causes painful sores on the genitals and is only spread through sexual contact.

This infection is more common in developing nations, especially among commercial sex workers and some lower socioeconomic groups. This is due to the lack of access to healthcare services, the stigma attached to seeking help, a lack of sufficient sexual health education, and other factors.

In 2015, just 11 cases of chancroid were reported in the United States. Chancroid increases the risk of contracting HIV, and HIV increases the risk of contracting chancroid.

Within 1 day to 2 weeks of acquiring the infection, the patient develops a bump that turns into an ulcer within a day. The ulcer can be from 1/8 of an inch to 2 inches across. It will be very painful and may have well-defined, undermined borders and a yellowish-gray material at its base.

If the base of the ulcer is grazed, it will typically bleed. In some cases, the lymph nodes swell and become painful.

Women often have at least four ulcers, while men usually have just one. Males tend to have fewer and less severe symptoms. The ulcers typically appear at the groove at the back of the glans penis in uncircumcised males, or, in females, on the labia minora or fourchette.

Chancroid is treated with a 7-day course of erythromycin, a single oral dose of azithromycin, or a single dose of ceftriaxone.

Crabs, or pubic lice

Pubic lice manifestations are primarily spread through sexual contact. Pets do not play any part in the transmission of human lice.

The lice attach to the pubic hair, and may also be sometimes found in the armpits, mustache, beard, eyelashes, and eyebrows. They feed on human blood.

The common term “crabs” comes from the crab-like appearance of the lice.

Genital herpes

This STDs is caused by the herpes simplex virus (HSV). The virus affects the skin, cervix, genitals, and some other parts of the body.

There are two types:

  • HSV-1, also known as herpes type 1
  • HSV-2, also known as herpes type 2

Herpes is a chronic condition. A significant number of individuals with herpes never show symptoms and do not know about their herpes status.

HSV is easily transmissible from human to human through direct contact. Most commonly, transmission of type 2 HSV occurs through vaginal, oral, or anal sex. Type 1 is more commonly transmitted from shared straws, utensils, and surfaces.

In most cases, the virus remains dormant after entering the human body and shows no symptoms.

The symptoms associated with genital herpes, if they do occur, may include:

blisters and ulceration on the cervix

  • vaginal discharge
  • pain on urinating
  • fever
  • generally feeling unwell
  • cold sores around the mouth in type 1 HSV

Also, red blisters may occur on the external genital area, rectum, thighs, and buttocks. These can be painful, especially if they burst and leave ulcers.

Hepatitis B

The hepatitis B virus (HBV) causes this STD.

It is transmitted through contact with infected semen, blood, and other bodily fluids. HBV is passed on in the following ways:

  • unprotected sex
  • using an unsterilized syringe
  • being accidentally pricked by a sharp object
  • drinking infected breast milk
  • being bitten by a person with hepatitis B

The liver swells, and an individual can experience serious liver damage as a result of HBV. This can eventually lead to cancer, and the disease can sometimes become chronic. Blood donation centers always check to make sure that any donors do not have hepatitis B.

Scabies

Scabies is a contagious skin condition caused by Sarcoptes scabiei, a tiny mite. They burrow into the skin and lay their eggs.

A person with scabies develops a skin rash and experiences intense itchiness. People with scabies are often unaware of their condition for several weeks after initial infection, which means scabies infestations spread rapidly.

The cause of scabies is unknown, although some believe poor living conditions and a lack of personal hygiene are linked to the condition. However, there is no scientific proof of this.

Scabies is most commonly transmitted through close body contact, such as holding hands for a long time or sexual intercourse. Hugging or simply shaking hands with a person who has scabies is unlikely to lead to transmission.

The scabies mite cannot jump or fly. However, it can survive for 1 to 2 days after leaving the human body. This means that sharing clothes or bedding with a person who has scabies increases the risk of infection.

However, prolonged physical contact, as is likely to occur during sexual intercourse, is the most common route of transmission.

Symptoms of scabies may not occur for several weeks after initial transmission and may include:

  • A skin rash: The scabies mite leaves small red spots, known as burrow marks. They look like tiny insect bites, and some people may think it is eczema. Burrow marks typically appear as a small line of at least four tiny spots and appear around the area of the elbows, wrists, and in between the toes and fingers. Women experience this rash around the nipples and men near the genitals.
  • Intense itching: This gets worse at night or after taking a hot shower.
  • Sores: After scratching the rash, the area can become inflamed, and crusty sores may develop.

Less commonly, the rash may appear on the buttocks, ankles, armpits, genitalia, groin, scalp, neck, face, head, shoulders, waist, soles of the feet, lower leg, and knees.

Syphilis

Syphilis is the result of Treponema pallidum, a bacterium. It is transmitted by sexual contact, and the person passing on the infection will have a syphilitic lesion. A woman who is pregnant and also has syphilis can pass on this STDs to her baby, which can result in stillbirth or serious congenital deformities.

There is an incubation period of between 9 and 90 days after initial infection before the symptoms of the disease occur, with an average incubation period of 21 days. Each stage of syphilis has characteristic signs and symptoms. Some people with syphilis show no symptoms, while others may experience more mild presentations.

For some people with the condition, even if symptoms resolve, the bacterium is still in the body and can cause serious health problems later on.

Gonorrhea

This sexually transmitted bacterial infection usually attacks the mucous membranes. It is also known as the clap or the drip.

The bacterium, which is highly contagious, stays in the warmer and moister cavities of the body.

The majority of women with gonorrhea show no signs or symptoms. If left untreated, females may develop pelvic inflammatory disease (PID). Males may develop inflammation of the prostate gland, urethra, or epididymis.

The disease is caused by Neisseria gonorrhoeae. The bacteria can survive in the vagina, penis, mouth, rectum, or eye. They can be transmitted during sexual contact.

As soon as a person contracts gonorrhea, they risk spreading the bacteria to other parts of the body. An individual may accidentally rub their eye and spread the infection. This prolongs the treatment period. A woman who is pregnant can pass the infection on to the infant during childbirth.

Symptoms of gonorrhea may occur between 2 to 10 days after initial infection, in some cases, it may take 30 days. Some people experience very mild symptoms that lead to mistaking gonorrhea for a different condition, such as a yeast infection.

Males may experience the following symptoms:

  • burning during urination
  • testicular pain or swelling
  • a green, white, or yellow discharge from the penis

Females are less likely to show symptoms, but if they do, these may include:

  • spotting after sexual intercourse
  • swelling of the vulva, or vulvitis
  • irregular bleeding between periods
  • pink eye, or conjunctivitis
  • pain in the pelvic area
  • burning or pain during urination

If the rectum becomes infected, a person with gonorrhea may experience anal itching, painful bowel movements, and sometimes discharge. When transmission occurs as a result of oral sex, there may be a burning sensation in the throat and swollen glands.

Prevention

What you should  know about STDs

Sex using a condom is the safest way to prevent the spread of STDs. Condoms are known as barrier contraceptives, due to their presentation of a physical barrier to microbes.

For each oral, vaginal, or anal sex act, use a new latex condom. Condoms are available to purchase online.

Avoid using an oil-based lubricant, such as petroleum jelly, when using a latex condom. Non-barrier forms of contraception, such as oral contraceptives or intrauterine devices, do nothing to protect people from sexually transmitted infections.

Here are other steps you can take to reduce the risk of an STDs:

  • Abstinence: Abstaining from any sexual act is the most effective way to avoid an STD.
  • Monogamy to one uninfected partner: A long-term, monogamous relationship with one person who is not infected can reduce the risk of contracting an STD.
  • Vaccinations: There are vaccinations that can protect an individual from eventually developing some types of cancer that are caused by HPV and hepatitis B.
  • Check for infections: Before sexual intercourse with a new partner, check that the partner and yourself have no STDs.
  • Drink alcohol in moderation: People who have consumed too much alcohol are more likely to engage in risky behavior. Avoid using recreational drugs, which may also affect judgment.
  • Explain you want safe sex: Before engaging in any sexual act with a new partner, communicate that you would only consider safe sex.
  • Education: Parents, schools, and society need to teach children about the importance of safe sex, and explain how to prevent becoming infected with an STDs, including information relevant to the LGBTQ community.

Take a responsible approach to getting intimate with another person, and it could protect you from a range of health problems further down the line.
