Will there be any meals at the conference?

Attendees are on their own for most meals. However, we will provide a light continental breakfast on Monday, Tuesday, and Wednesday. Snacks will be available in the poster hall on Monday, Tuesday, and Wednesday. The Welcome Reception will take place directly following the opening sessions on Sunday, February 22, and will include drinks and light hors d’oeuvres.

Will there be a kosher food option available?

Attendees are on their own for most meals during the conference. When event food is provided, CROI offers a variety of food choices (ie, gluten-free, vegetarian, vegan). If you have dietary restrictions or needs beyond those listed, we recommend arranging alternate food sources.

Registration

When will registration open?

General application and registration opened on October 22, 2025.

When does registration close?

Registration will close on February 11, 2026, or earlier if capacity is reached. If you plan to attend, we encourage you to complete your registration as soon as possible.

Please note that if you need to apply to register, allow sufficient time for review, as applications are typically processed within 2 to 3 business days. You must receive your application decision before registering, so we encourage you to submit your application well in advance of the registration deadline. To avoid delays, ensure your application is complete, as resubmissions generally take longer to process than initial submissions.

What is included in the registration fee?

The registration fee includes access to the conference and the conference materials.

Is CROI 2026 going to have a virtual registration?

Yes, however, virtual registration provides access to live presentations and on-demand content only.

I live in Denver, CO. Do I still need to book a hotel?

If you live within a 50-mile radius of the Colorado Convention Center and intend to commute, you can submit a housing exemption request through the CROI Dashboard before beginning your registration process.

I need to update my registration or hotel reservation. Where should I send the request?

To make updates to your registration, please email your request to CROIregistration@iasusa.org.

For hotel reservation changes, please contact Meetingmax, the official CROI housing partner, at croi-housing@meetingmax.cc, or follow the instructions included in your hotel reservation confirmation email for making changes.

I submitted my application. When will I be notified of my application status?

Applications are typically reviewed within 2 to 3 business days. Once a decision has been made, you will be notified by email.

I am paying by check or wire transfer. How long will you hold my hotel reservation, which I have guaranteed with a credit card?

Full registration payment must be received within 2 weeks of when the hotel reservation was made. If payment is not received within this timeframe, your hotel reservation will be canceled.

I have attended in the past. Why do I need to provide recent publications?

This is to ensure you are eligible to attend based on the most recent information you can provide us to determine your attendance eligibility. CROI is strictly a scientific conference and we want to ensure those who attend are in research in HIV or related fields to ensure that can learn and participate. You may have met the eligibility criteria to attend in the past but we still need to verify that you currently meet the eligibility for attending.

How can I change my hotel reservation or switch to another hotel?

Please contact Meetingmax, the official CROI housing partner, at croi-housing@meetingmax.cc, or follow the instructions included in your hotel reservation confirmation email to make changes.

I need to cancel my registration and hotel reservation. How do I request a cancellation, and what is the deadline?

The deadline to cancel your registration and hotel reservation was January 14, 2026. Cancellation requests must be submitted in writing to CROIregistration@iasusa.org.  Please note that no refunds will be issued for cancellations received after January 14, 2026. Your in-person registration will be converted to a virtual registration.

I am unable to obtain my visa in time. Can I cancel my registration and receive a full refund?

Unfortunately, we are unable to offer a refund or cancellation due to visa delays. We recommend completing your registration once your visa is confirmed. We can assist in converting your registration to a virtual registration upon request.

I need to cancel my in-person registration and would like a refund.

The deadline to request a cancellation with a refund was January 14, 2026. We will convert your registration to virtual. Please reach out to Meetingmax, the official CROI housing partner, at croi-housing@meetingmax.cc to cancel your hotel reservation, if applicable.

I am a US federal employee planning to attend CROI, but my approval is still pending. What should I do now?

We understand that federal approval processes can be complex and may take longer this year.  

If you intend to attend CROI and would like to secure a spot without using personal funds at this time, we recommend submitting an application. Once your application is approved, you may book your hotel accommodation at the government per diem rate.  

However, please delay completing your conference registration and payment until you receive final approval from your agency, as registration fees are non-refundable after January 14, 2026. This approach allows you to secure lodging before rooms sell out while avoiding out-of-pocket expenses. 

What happens if my in-person travel is not approved or I am approved to attend virtually instead?

If you have registered, paid the conference fee, and booked a hotel but do not receive authorization for in-person travel, please cancel your hotel reservation and notify us immediately so we can convert your registration to virtual attendance.  

Most hotels allow cancellation without penalty if canceled within 24–72 hours of arrival. There is no additional fee to convert an in-person registration to virtual attendance.
