Symptoms of STDs caused by protozoan


  • Frothy vaginal discharge with a strong odor
  • Treated with antibacterial/antiprotozoal medicines

Symptoms of STDs* caused by fungi*

Jock itch (genital itching or Tenia cruris)* (not always an STD)

  • Itchy groin skin, sometimes has a reddish color
  • Is treated with topical antifungal medicines

Yeast infection (Candidiasis)* (not always an STD)

  • Cheese-like vaginal discharge or whitish exudates sometimes with a reddish hue to the skin; it may occur around the foreskin of infected males; common symptoms are itching and burning sensation of the vagina or penis.
  • Is treated either with topical or oral antifungal medicines.

Symptoms of STDs caused by parasites

Pubic lice

  • Very tiny bugs that are found in pubic hair, sometimes referred to as "crabs"
  • Can be picked up from clothing or bedding
  • First noticed as itching in the pubic area
  • Are treatable with creams, anti-lice agents, and combing


  • Skin infestation caused by a tiny mite
  • Highly contagious
  • Intense itching is the primary symptom, which worsens at night
  • Spread primarily by sexual contact or from contact with skin, infested sheets, towels, or furniture
  • Is treated with creams

When Should I Call a Doctor about STDs?

A medical examination may be necessary if a person believes he or she may have an STD or if he or she may have been exposed to someone with an STD. Being seen by a doctor as soon as possible after exposure to an STD is important; these infections can easily spread to others and can have serious complications.

Go to your primary care physician or an urgent care center or STD clinic in these circumstances if:

  • an STD problem worsens or
  • a fever develops with other symptoms.

How Are Sexually Transmitted Diseases (STDs) Diagnosed?

Some STDs can be diagnosed without any tests at all (for example, pubic lice). Other STDs require a blood test or a sample of any unusual fluid (such as an abnormal discharge from the vagina or the penis for gonorrhea or chlamydia) to be analyzed in a lab to help establish a diagnosis. Some tests are completed while a person waits; other tests require a few days before a person may obtain the results (for example, syphilis).

Are there Home Remedies for Sexually Transmitted Diseases (STDs)?

Home treatment of STDs is not recommended because prescription medications are usually necessary.
