Yes, in most cases you can donate plasma if you have herpes. HSV isn't a bloodborne infection and doesn't permanently disqualify you. Don't donate during an active outbreak; wait until sores are dry and healed, feel well, and disclose your status. Antivirals like valacyclovir are usually fine, but rules vary by center.

Why Doesn't Herpes Disqualify You?

Herpes simplex virus does not circulate through the bloodstream way HIV or hepatitis does. HSV lives in nerve cells and typically only reaches skin's surface during an outbreak. Research has shown that herpes DNA can appear in plasma during primary (first ever) infection, but it is not detectable in blood during recurrent outbreaks in otherwise healthy individuals.

Because of this, herpes is not considered a bloodborne infection in same category as HIV, hepatitis B, or hepatitis C. Those conditions permanently disqualify someone from donating. Herpes does not. It is treated as a temporary deferral, meaning you just need to wait until your outbreak has resolved before you can donate.

The NIH Blood Bank states directly that you cannot donate when herpes lesions are active, but you can donate once lesions are dry and nearly healed: NIH blood donation eligibility guidelines.

What Are Rules for Donating With Herpes?

The specific requirements can vary slightly between donation centers, but general guidelines are consistent.

You must not have any active sores, blisters, or lesions at time of donation. This applies to both oral herpes (cold sores) and genital herpes. The sores need to be fully dried and in final stages of healing.

You should wait at least 48 hours after finishing a course of antiviral medication like valacyclovir (Valtrex) or acyclovir before donating. These medications are not harmful to a plasma recipient, but donation centers want to ensure your outbreak is genuinely resolved and not just being suppressed by drug.

You will go through a standard screening process that includes health questionnaire and a brief physical check. Be honest about your herpes status and any recent outbreaks. Everything you share with medical staff is confidential and is used solely to determine your eligibility.

If you are experiencing your very first herpes outbreak, most centers will ask you to wait longer before donating. A primary infection is more likely to produce detectable virus in blood compared to recurrent outbreaks. Waiting until initial infection fully resolves and your immune response stabilizes is safest approach.

What About Other STDs?

Herpes is handled differently from several other sexually transmitted infections when it comes to plasma donation. Here is how other common STDs compare.

HIV, hepatitis B, and hepatitis C permanently disqualify you from donating plasma. These are bloodborne infections that pose a direct risk to recipients.

Syphilis and gonorrhea require a three-month waiting period after completing treatment. Once treatment is finished and you are symptom-free for three months, you can donate again.

Chlamydia and HPV generally do not disqualify you from donating, as long as you meet other standard eligibility criteria and feel well at time of donation.

And if you are trying to tell whether a bump is herpes or something else entirely, this comparison on herpes vs pimple can help you figure it out before your appointment.

What Happens at Donation Center?

When you arrive, you will fill out a detailed health questionnaire that covers your medical history, recent illnesses, medications, and sexual health. A staff member will then do quick physical check that includes blood pressure, temperature, and hemoglobin test.

Plasma centers also test every donation for bloodborne pathogens including HIV, hepatitis B, and hepatitis C. Herpes is not part of standard plasma screening panel because it is not transmitted through transfusion under normal circumstances.

If you pass the screening, donation process itself takes about 60 to 90 minutes. Your blood is drawn, plasma is separated out, and your red blood cells are returned to you with saline solution. You can typically donate plasma twice within a seven day period, with at least one day between sessions.

Conclusion

Herpes does not prevent you from donating plasma. You just need to wait until any active outbreak has fully healed and you have been off antiviral medication for at least 48 hours. Be upfront with donation center staff about your medical history, and you will be guided through the process. Unlike HIV or hepatitis, herpes is not a bloodborne infection that permanently disqualifies you. Millions of people with HSV-1 and HSV-2 donate plasma safely every year.

Frequently Asked Questions

Yes, in most cases. Herpes (HSV-1 or HSV-2) is not a bloodborne infection, so it does not permanently disqualify you from donating plasma. You generally just need to be free of an active outbreak, feel well, and pass the center's standard screening.

No. Donation centers treat HSV-1 and HSV-2 the same way for eligibility, and oral cold sores and genital herpes follow identical rules. What matters is whether you have active lesions at the time of donation, not the type or location of the virus.

No, you should not donate while sores, blisters, or lesions are active. Wait until they are dry, crusted over, and healed (or nearly healed). Many centers ask you to wait roughly 48–72 hours after the lesions fully heal before you give.

For a recurrent outbreak, you can usually donate once the lesions are completely healed and you feel well; some centers add a short 48–72 hour buffer. Specific waiting periods vary, so confirm the exact timeline with your donation center.

Usually, yes, antiviral medication does not disqualify you, and these drugs are not harmful to a plasma recipient. The American Red Cross does not defer donors for taking them, though some commercial plasma centers ask you to wait about 48 hours after your last dose to confirm the outbreak has truly resolved.

A first (primary) outbreak usually means a longer wait, because HSV can briefly be detectable in the blood during a primary infection. Blood-donation guidance often suggests waiting about a month, while some commercial plasma centers ask for several months after diagnosis. Always check your center's policy.

No. Herpes simplex virus lives in nerve cells and only reaches the skin's surface during an outbreak, it does not circulate in the bloodstream the way HIV or hepatitis does. That is why HSV poses very little transmission risk through plasma and is treated as a temporary deferral, not a permanent ban.

Routine donor screening tests for HIV, hepatitis B and C, and syphilis, not for HSV. In healthy people, herpes DNA is not detectable in blood during recurrent outbreaks, so a past diagnosis will not normally flag a screening test.

The core rules are the same, because plasma is a component of blood, no active lesions and you must feel well. The main difference is that commercial "source plasma" centers (CSL, BioLife, Octapharma) can set stricter or longer waiting periods than Red Cross blood drives, so policies differ by location.

HIV, hepatitis B, and hepatitis C are permanent disqualifiers because they spread through blood. Syphilis and gonorrhea cause a temporary deferral, typically about three months after you finish treatment and are symptom-free.

HPV generally does not disqualify you, since it is not transmitted through blood. Chlamydia and gonorrhea are temporary deferrals: once you have completed treatment and are symptom-free for the required window, you can usually donate again.

Yes, answer the health questionnaire honestly, including any recent outbreaks or medications. The information is confidential and is used only to confirm your eligibility and protect recipients.
