Can I infect someone if I'm undetectable?

Undetectable = Untransmittable (U=U) A person living with HIV who is on treatment and maintains an undetectable viral load has zero risk of transmitting HIV to their sexual partners. Sustained antiretroviral treatment (ART) reduces the amount of HIV in the body to undetectable levels in viral load tests.

Can you infect someone if you're undetectable?

People with HIV who take HIV medicine as prescribed and get and keep an undetectable viral load will not transmit HIV to their HIV-negative partners through sex. This is sometimes called treatment as prevention or undetectable = untransmittable (U=U).

Is undetectable 100% safe?

Yes, for HIV, "undetectable equals untransmittable" (U=U) means a person with an undetectable viral load due to consistent antiretroviral therapy (ART) has zero risk of sexually transmitting HIV, making it effectively 100% safe for preventing transmission, a concept proven by extensive studies and supported by health organizations like the CDC. This means the virus is so low in the blood it can't be transmitted to sexual partners, but it doesn't mean the person is cured or that the virus is gone from the body, so continued medication adherence is crucial. 

How can I boost my viral load?

Natural methods to boost CD4 levels may include supplementing certain vitamins, such as vitamin D. However, the quickest and most effective way to boost CD4 levels is to start antiretroviral therapy (ART).

Does an undetectable status mean the virus is gone?

Despite having an undetectable viral load, the virus is still present in the body. If therapy is stopped, the viral load can become detectable once again. Maintaining consistency in taking medication is essential to sustain undetectability.

Should you tell people you're HIV+ if you're undetectable?

Do I have to disclose if I'm undetectable?

It's up to you to decide when you're ready to talk about your HIV with others. You should never feel rushed or pressured into it – take your time if you need to. Understanding that Undetectable = Untransmittable (U=U) has helped many people living with HIV feel more confident about their status.

Do I have to tell someone I'm undetectable?

If I have an undetectable viral load or use a condom, do I still need to disclose my status to sexual partners? In most states with an HIV-specific criminal law, your viral load is not a factor in whether you must disclose your HIV-positive status; a few states, however, do take condom use into account.

Should I get tested even if my partner is undetectable?

It is also good to get tested together with your partner to be sure of your HIV status. If you know your partner has HIV, their viral load can help you decide if you need PrEP or not. If your partner has an undetectable viral load, you do not need to use PrEP, as there's no risk of transmission.

Can you stay undetectable forever?

No, you can't stay undetectable forever in an absolute sense, especially with conditions like HIV, but with consistent treatment, people can maintain an undetectable viral load (U=U) indefinitely, meaning zero risk of transmission, though lapses in medication, drug resistance, or viral reservoir issues can make it detectable again. Undetectable means the virus is present but too low to measure, requiring continuous daily medication and regular check-ups to stay that way.
 

Should I date someone who is undetectable?

If your partner is taking HIV treatment and has an undetectable viral load, there is no risk of HIV transmission. Using condoms is also an effective way of preventing HIV transmission during sex.

What is the life expectancy of someone on ARVs?

Studies have shown that for people living with HIV, the average life expectancy is very similar. One study of people found that people with a high CD4 count (above 500) who started taking ART after 2015, had a life expectancy similar to the general population—77 years of age for men and 79 for women.

How long can you go without biktarvy?

If you miss a dose of Biktarvy® and it is less than 18 hours from when you normally take it, take the dose immediately. If it is more than 18 hours from when you normally take Biktarvy ®, do not take the dose and wait until your next scheduled dose.

What happens if you sleep with someone who is on Arvs?

(See resistance testing for an explanation of what it means for the virus to be resistant.) For a person with HIV who is taking antiretroviral medicine and has an undetectable viral load, the risk of infecting someone else (or becoming re-infected) through sex is extremely low.

Is undetectable really undetectable?

U equals U. That stands for “Undetectable equals untransmittable.” Being undetectable means there's so little HIV in the blood that it can't be measured by a laboratory test. It's scientifically proven.

Can I infect my partner if I'm undetectable?

If your partner has been diagnosed with HIV, has been taking HIV medication for at least 6 months, and their viral load is undetectable, there is no risk of HIV transmission through sex.

Does undetectable mean not contagious?

Undetectable = Untransmittable (U=U)

A person living with HIV who is on treatment and maintains an undetectable viral load has zero risk of transmitting HIV to their sexual partners. Sustained antiretroviral treatment (ART) reduces the amount of HIV in the body to undetectable levels in viral load tests.

Will I test positive if I'm undetectable?

Undetectable doesn't mean that you're cured — you'll still test positive on other HIV tests. HIV can stay inactive in your cells and reactivate if you stop taking ART medications. Being undetectable or having a low viral load means that your ART medications are working well.

How long can a person survive without ARVs?

Without treatment

The Centers for Disease Control and Prevention (CDC) states that once people receive an AIDS diagnosis, they typically live for 3 years . In the early years of the HIV epidemic, when no treatments were available at all, many people only lived around 1–2 years after receiving a diagnosis.

Can I drink alcohol while taking ARVs?

HIV treatment and alcohol

There are no significant interactions between alcohol and HIV drugs. However, you may forget to take your HIV treatment when under the influence of alcohol and heavy drinking will harm your health.

Can a person taking ARVs test positive?

Even on treatment you will still test positive. ARVs are used to treat HIV but you will still be HIV positive. This is because ARVs suppress HIV but your body will still have an immune response to the initial infection – this is why you will still test positive.

Can I drink alcohol while taking Biktarvy?

Biktarvy hasn't been reported to interact with alcohol. However, if you have certain side effects with Biktarvy, drinking alcohol could make them worse. Examples of Biktarvy side effects that could be worsened by alcohol include headache, nausea, and diarrhea. In addition, Biktarvy can sometimes cause liver problems.

What happens if I take 2 Biktarvy in one day?

If you do miss a dose of Biktarvy, take it as soon as you remember. But if it's almost time to take your next dose, do not “double dose” Biktarvy by taking two tablets. Doing this can increase your risk of side effects. Instead, skip your missed dose and take your next dose as scheduled.

How fast does viral load drop on Biktarvy?

Biktarvy starts reducing the HIV viral load in a little as 4 weeks and continues to decrease the levels over the first 3 to 6 months to usually become undetectable.

Do ARVs affect the brain?

People who are using highly active antiretroviral therapy, known as HAART, are less likely to develop HIV-associated dementia. Experts think this may be because these drugs help maintain the overall immune system.

Do you have to take Biktarvy forever?

Medically reviewed by Leigh Ann Anderson, PharmD. Last updated on Aug 4, 2025. Biktarvy antiretroviral therapy (ART) is taken indefinitely for HIV-1 infection as it is a complete regimen for long-term treatment.
