U=U: What “Undetectable Equals Untransmittable” Really Means

By Dr. Anthony Jones, MD · June 3, 2026 · 4 min read

If you're on HIV treatment and your viral load is undetectable, you cannot pass HIV to a sexual partner. Here's the science behind U=U — and why it changes everything.

U=U stands for “Undetectable equals Untransmittable.” It means that when a person living with HIV takes their medication consistently and reaches an undetectable viral load, they cannot transmit HIV through sex. This is settled science — and it has transformed how we talk about HIV.

What this looks like in practice

We meet people where they are. That means short, honest conversations, plain-language answers, and a plan that fits your life — not a one-size-fits-all script.

  • Same-day appointments are often available.
  • Tuesday evenings open until 8 pm.
  • Telehealth visits when you can't come in.
"Good medicine is a relationship — not a transaction."
