💊 About PrEP

Pre-exposure prophylaxis (PrEP) is a daily medication that can prevent HIV infection when taken consistently by high-risk individuals.

•Over 99% effective when taken daily
•Recommended for high-risk individuals
•Requires regular medical monitoring
•Covered by most insurance plans

Understanding the Denver HIV Risk Score

What is HIV?

HIV (Human Immunodeficiency Virus) attacks the body's immune system, specifically CD4+ T cells. Without treatment, HIV can progress to AIDS (Acquired Immunodeficiency Syndrome), making the body vulnerable to life-threatening infections and cancers.

HIV Transmission Routes:

  • •Sexual contact: Unprotected anal or vaginal sex
  • •Blood contact: Sharing needles, syringes, or injection equipment
  • •Vertical transmission: Mother to child during pregnancy, birth, or breastfeeding
  • •Blood transfusions: Rare in countries with safe blood supply

Why Use the Denver HIV Risk Score?

The Denver HIV Risk Score was developed to help healthcare providers identify individuals at highest risk for HIV infection, enabling more targeted and cost-effective testing strategies in clinical settings.

Clinical Applications:

  • •Emergency department screening
  • •Primary care risk assessment
  • •Urgent care HIV testing decisions
  • •Public health screening programs

Note: This score was originally developed and validated primarily in men who have sex with men (MSM) populations and may not be equally applicable to all demographic groups.

HIV Prevention and Treatment

Prevention

Pre-Exposure Prophylaxis (PrEP)

Daily medication for high-risk individuals - over 99% effective

Safe Sex Practices

Consistent condom use, limiting partners, regular STI testing

Harm Reduction

Clean needles, needle exchange programs, substance abuse treatment

Testing

Regular Testing

Annual testing for average risk, more frequent for high risk

Window Period

Time between infection and detectability - usually 2-4 weeks

Test Types

Rapid tests, blood tests, oral fluid tests available

Treatment

Antiretroviral Therapy (ART)

Highly effective treatment - can achieve undetectable viral loads

Undetectable = Untransmittable

People with undetectable viral loads cannot transmit HIV sexually

Life Expectancy

With treatment, HIV+ individuals can have near-normal lifespans
