STD Types, Symptoms, and Prevention Methods (Part 1)

Sexually transmitted Infections or Diseases (STIs, STDs) are infections that are carried from one person to another through sexual contact. The contact is typically vaginal, oral, or anal. However, they can sometimes spread through other intimate physical contacts. This is due to the fact that some STDs, such as herpes and HPV, are spread through just skin-to-skin contact.

Some STIs are harmless, but others can cause serious complications if left untreated. HIV, for example, has multiple routes of transmission. This STI, for example, can spread through the use of contaminated drug needles as well as sexual contact. STIs can affect anyone, regardless of sexual orientation or hygiene practices. Many STIs can also be transmitted via non-penetrative sexual activity.

According to WHO, every day, around 1 million STIs are acquired around the globe. They also predict 374 million cases of infections with one of four STIs in 2020: chlamydia (129 million), gonorrhoea (82 million), syphilis (7.1 million), and trichomoniasis (156 million). 

The numbers are alarming but these diseases can be prevented. Learn about some STIs, how to prevent them, and when to seek medical attention.

The Various Causes of STD

STDs or STIs can be caused by:

Bacteria:  Syphilis, Gonorrhea, and Chlamydia are some of the STIs that are caused by bacteria.

Parasites: Trichomoniasis is an STI caused by a parasite.

Viruses: STIs caused by viruses include HPV, genital herpes, and HIV.

Other kinds of infections: hepatitis A, B, and C viruses, shigella infection, and giardia infection. They can be spread through sexual activity, but it’s possible to be infected without sexual contact.

Risk Elements:

Anyone who engages in sexual activity runs the risk of contracting an STD or STI. The following factors may increase the risk:

Having sex without protection. Vaginal or anal penetration by an infected partner who isn’t wearing a latex condom increases the risk of contracting an STI significantly. Improper or inconsistent usage of condoms can also raise the risk.Although oral sex is less dangerous, infections can still be transmitted if a latex condom or a dental dam( a thin, square piece of latex or silicone rubber)  is not used.Having sexual contact with more than one partner. The more people with whom you have sexual contact, the higher your risk.Having an STI history. The presence of one STI makes it much easier for another to take hold.Being coerced into sexual activity. It is difficult to deal with rape or assault, but it is critical to see a doctor as soon as possible to receive screening, treatment, and emotional support.Misuse of alcohol or recreational drug use, and substance abuse can impair judgement, making you more willing to engage in risky behaviours.Drug injection Many serious infections, including HIV, hepatitis B, and hepatitis C, are spread through needle sharing.Half of all new STIs are diagnosed in people aged 15 to 24.

Types of STDs

Pelvic Inflammatory Disease (PID)

A variety of microorganisms can cause upper female reproductive tract pelvic inflammatory disease. Chlamydia trachomatis and Neisseria gonorrhoea are the two most common pathogens, accounting for four out of every five cases.

PID caused by chlamydia infection usually has mild or no symptoms, but it should be treated as soon as possible. Otherwise, it can inflame and scar the ovaries and fallopian tubes, just like other types of PID. Furthermore, because PID affects the fallopian tubes, where conception occurs, the female may experience lower abdominal pain. In other words, sterility may be the end result of PID.

Symptoms

Lower abdominal discomfortVaginal discharge that is abnormalFeverIntercourse that is painfulMenstrual irregularities

HIV and Aids

AIDS is caused by the human immunodeficiency virus (HIV), spread through unprotected sexual contact with an infected person or by injecting drugs with a contaminated needle. It can also be transmitted through intravenous drug use. In addition, it can also be transmitted through blood, blood products, needles, or other sharp instruments contaminated with infected body fluids or blood.

When HIV microorganisms enter the bloodstream, they abduct a type of white blood cell known as T-helper lymphocytes (also known as CD4 cells, T cells, or helper-Ts). T-cells in a healthy immune system work together to help the body defend itself against diseases. However, the hijacked T-cells are forced to replicate HIV in large numbers. If left untreated, helper T cells produce large amounts of HIV, depleting the number of normal helper-T cells in the bloodstream and making the individual vulnerable to the AIDS-defining illness.

The five most common are as follows:

Pneumonia caused by Pneumocystis cariniiAIDS-related wasting syndromeCandidiasis of the stomachTuberculosisSarcoma of Kaposi

When the immune system is functioning properly, opportunistic illnesses pose little threat; however, when the body’s defenses are compromised, as in AIDS, they seize the opportunity to wreak havoc.

However, for the first ten years of the AIDS crisis, the disease was a virtual death sentence for most of those who contracted it. Few people live for more than two years on average. Today, however, there are many different types of HIV medications available. While HIV remains incurable, good medication adherence can allow those infected to live long and productive lives without developing AIDS.

Symptoms

HeadachesDifficulty swallowingFeverNight sweatsFatigue/weaknessAppetite lossWeight lossChronic diarrheaNausea/vomitingItchy, rashy skin/skin lesionsChronic coughingConfusion/deliriumDifficulty breathing

Gonorrhea

Chlamydia infection is sometimes confused with gonorrhoea, a bacterial infection spread through vaginal, anal, and oral sex. Not only do they share many of the same symptoms, but they can also occur concurrently.

The urethra (bladder opening) or the cervix is where gonorrhoea usually begins. The rapidly proliferating Neisseria gonorrhoeae bacterium, on the other hand, can migrate to the uterus and fallopian tubes, causing pelvic inflammatory disease (PID). The infection, like chlamydia, can affect the rectum.

Symptoms

Two to ten days after exposure, symptoms usually start to manifest.

Men:

Penile ejectionBurning when urinating that ranges from mild to severeCan develop into epididymitis

Women:

Yellow or bloody vaginal discharge in addition to a painful or burning sensation when urinatingstomach acheBleeding in the interim between cyclesVomitingFeverDevelopment of pelvic inflammatory disease

Rectal Infection:

Anal dischargeAnal itchingPainful bowel movements

Chlamydia

Chlamydia, the most common bacterial STI, is caused by the Chlamydia trachomatis bacterium, which can infect the urethra and cervix (uterus opening). It is common among adolescents aged fifteen to nineteen. The disease is easily treated, but, like other sexually transmitted infections, chlamydia is often silent and thus goes undiagnosed until it has progressed to a more serious stage. 

Three out of every four women and one out of every two men have no symptoms. Hence, by the time a girl seeks medical attention, the disease has progressed to pelvic inflammatory disease (PID, as described above), a major cause of female infertility and pelvic pain in 40% of cases.

Symptoms

The symptoms begin to appear one to three weeks after exposure.

Women:

Unexpected vaginal dischargeAn increase in pelvic inflammation

Men:

Penile expulsionDiscomfort when urinatingProgress to epididymitis, an inflammation of the sperm-transporting and storage tube-like structure

Genital Herpes (HSV-1, HSV-2)

Herpes simplex viruses, which cause genital herpes, are classified into two types. Also, herpes simplex 2 is commonly found on or around the vagina, penis, anus, buttocks, and thighs. Herpes simplex type 1a second type which causes cold sores around the outside of the mouth, as well as blisters on the gums or in the throat. HSV-1, on the other hand, can infect the genital-anal area, and both types can be transmitted to the mouth via oral sex.

Genital herpes is a chronic, lifelong condition because the virus permanently infects sensory nerves at the base of the spinal cord. HSV is dormant the majority of the time. Occasionally it reactivates, causing sores or vesicles, most notably tiny ulcers that resemble cold sores. These outbreaks, which usually last about a week, should be interpreted as a sign that the disease is contagious. The virus spreads up the nerves that lead to the skin’s surface, where it multiplies and causes new sores. (The initial symptoms of genital herpes are usually more severe and last longer than subsequent episodes.) Even if no sores or lesions are present, the disease can be contagious.

Symptoms

Symptoms appear two to ten days after exposure. Generally, the first episode lasts anywhere from two to three weeks:

Itching or burning sensation in the genitals, also known as the anusGenital, buttocks, and leg painDischarge from the cervixA feeling of abdominal pressureTiny red bumps on the vagina, cervix, penis, and/or anal area; develop into blisters, which then turn into painful open sores.Fever and HeadacheMuscle painUrination that is painful or difficult

Conclusion

There are several more significant varieties, symptoms, diagnoses, and preventative measures for sexually transmitted infections. Which will be covered in more detail in a subsequent (Part 2) of this article.
