1. What Is STI?

STI is an abbreviation term for Sexually Transmitted Infection. An infection is either a virus, parasite, or bacterial that enters the human body and develops to show signs and symptoms. Therefore, STI is an infection that spreads from one person to the next via sexual interactions involving body fluids. Play oral sex, and there you will still get it as you would in ordinary sex. 

Examples/ Types of STIs

There could be lots of STIs out there, some of which are not yet established.

  • Chlamydia
  • Trichomoniasis
  • Gonorrhea
  • Syphilis
  • Genital warts
  • Pubic lice
  • Genital herpes
  • Scabies
  • HIV

The most common one of these is HIV. It has spread worldwide and can only be detected by STD vs STI testing as it never shows any signs and symptoms.

Sexually Transmitted Disease(s); that is what the term STD stands for. When a sexually transmitted infection advances in your body to start causing severe signs and symptoms, we say that you have an STD. A better example is HIV, which is an infection. Once it develops and is accompanied by signs of weight loss, bruises and sores, sickly feeling, and so on. 

The Center for Disease Control and Prevention (CDC) statistics on STDs state that nearly 20 million STD infections occur every year in the United States (, 2017). Same as STIs, STDs transmit orally or through genital sexual interactions.

5 Risk Factors for Contracting an STD


STD signs and symptoms for women

  • Pains and discomfort during sex/ urination
  • Rashes, sores, or bumps, on or around the genitals; penis, anus, buttocks, testicles, thighs, and sometimes mouth
  • Unusual bleeding or discharge from the vagina
  • Itchiness in or around the vagina

4. STD Vs STI: Difference

From the definitions above, STDs and STIs are pretty similar except for their basic defining terms, disease, and infection. STDs are the advanced stages of STIs. A sexually transmitted disease starts as an infection that barely comes with noticeable signs and symptoms. Once it becomes a disease, you will begin to notice disruptions in your normal body functions. 

Why Do We Say STI Instead of STD?

We experience this quite a lot; many people prefer or at least feel better referring to various ill-health conditions as infections rather than diseases. A typical example is sexually transmitted ill-health conditions. So why did ‘infection’ come in so fast to replace ‘disease’? Stigma provoked it.

In the past, sexually transmitted diseases were referred to as venereal diseases; however, they disappeared with time. Today, and because of bad connotations still, the term ‘diseases’ has been dropped. 

Most people recently talk of ‘infection,’ which sounds much less serious. Fifty years from now probably, there will be another term replacing ‘infections – this also may be a ‘softer’ one to cushion the severity of the meaning.

While we cannot interchange the terms STDs and STIs, many people, including health practitioners, continue to avoid stigma. Not all people can sometimes bear the reality of their ill-health condition; hence such ‘straight’ words can affect them further. 

5. Is Chlamydia an STD or STI?

Chlamydia is both an STD and STI that affects both men and women. While still an infection, Chlamydia does not show any signs and symptoms when it advances to be a disease. 

Unlike other sexually transmitted diseases and infections, this condition is specifically known for its hazardous effects on women. When not treated in time, the disease can cause permanent barrenness. 

Chlamydia Is an STI

Chlamydia starts as a bacterial infection that multiplies, causing various ill-health conditions such as;

  • Chronic pelvic pain
  • Tubal factor infertility 
  • Pelvic inflammatory disease (PID)
  • Ectopic pregnancy

At this stage, research statistics indicate that an averagely of 90 percent of women and 70 percent of men show no signs and symptoms. Therefore, most people spread it without knowing; however, it may also spread via breastfeeding. 


4 Not-So-Common Facts About STDs/ STIs


Chlamydia Is an STD

From infection, Chlamydia will certainly advance to an STD, which now remains noticeable via the signs and symptoms that come along. 

Indicators at this stage include the following;

  • Unusual bleeding; between menstrual periods
  • Pain and discomfort during genital sex 
  • Lower abdominal pains
  • Fever
  • A burning sensation when urinating
  • Frequent urination
  • Unusual vaginal discharges
  • Bleeding, pain, itching, and mucus discharge from the rectum 
  • Itching and redness of the eyes

Like other infections and diseases in this category, there are many more signs and symptoms that may differ in the manifestation. So, how do you realize it is Chlamydia? Always seek quick medical attention whenever you note any of the above plus more. 

6. Treatment

At EZCare Clinic in San Francisco, we have one of the most professional procedures to handle such conditions. We will conduct comprehensive tests for ultimate diagnosis and treatment. 

Mostly, azithromycin and a couple of other antibiotics are the typical prescriptions for this condition. However, this may only be when you do not have any other underlying condition such as illness or pregnancy. In such cases, our health experts will advise accordingly. 

While Chlamydia remains curable, you should not remain careless to contact it anyhow. Sicknesses of any kind can be derailing and tormenting. The best way to avoid any of these is to embrace protection while having sex. We advise that you use a condom at our clinic whenever you are unsure about your partner’s health status—taking such precautions to safeguard you from acquiring Chlamydia and a lot more sexually transmitted diseases and infections.   

What’s worse, an STI or STD?

In case you are wondering which is worse between these two, the answer is so simple. STD being an advanced stage of an STI means it is the worse. All sexually transmitted diseases begin as infections, either bacterial, parasite caused, or virus. Once they start showing severe signs and symptoms, they become diseases. 

STD vs STI testing is pretty similar, especially for the same condition. Our EZCare facility in San Francisco has both the human resources and quality accessories to handle sexually transmitted diseases. We will assess your situation and give you the proper treatment.

Depending on the exact condition you are suffering from, either an infection or disease is always worse. HIV, for instance, automatically develops to aids that are non-curable. At all times, therefore, sexual protection is always key. If you are not playing sex, be careful about deep kisses, breastfeeding, and sharp objects sharing.
