All in-person CROI registrants are required to reserve a hotel room through the CROI housing system in order to attend CROI 2023. Exceptions are allowed if the registrant is a permanent resident in the Seattle area (ie, live within 50 miles of the Seattle Convention Center) or the registrant is sharing a room with an approved CROI attendee with accommodations booked via the CROI housing system. Other exceptions must be approved by the CROI organizers by submitting a hotel waiver. Please email the request to CROIregistration@iasusa.org.
If you have any special characters in your name, please be advised that you might receive an error message while trying to book your hotel reservation. If this error message occurs, please contact our housing partner, ConferenceDirect directly for assistance.

If you are sharing a room with an approved CROI registrant, who have book their reservation through CROI housing system or if you live within a 50 mile radius, you do not need to submit a separate hotel waiver request. Please indicate that in your registration during the registration process.
Please send the hotel waiver request to CROIregistration@iasusa.org. If you are staying with someone local, please provide the following information of the person you will be staying with in the email. Their full name, email address, address of where you are staying, and mobile number.
Because of the uncertainty of if everyone could travel this year, we are contracting hotel rooms incrementally. If you have not done so, please add yourself to the housing pending list. You can do this by logging in to your registration record and proceed through until you get to the registration confirmation page. Click “Book Hotel Reservation” to be taken to the CROI housing system. Select the check-in and check-out dates and click “Search”. You will then scroll until you see “Hotel Assignment Pending” and follow the onscreen prompts.
To modify your hotel reservation, please contact the selected hotel directly. Note: complete cancellation of your hotel stay might prompt cancellation of your conference registration
The submission deadline depends on the subject matter of the abstract (eg, general or late-breaking) Visit the Important Dates and Deadlines page for details on the varying submission deadlines for CROI.
I had an abstract submission system profile for a prior CROI. Why am I not able to access my profile?
CROI profiles for the abstract submission system are reset each year to ensure that updated information is obtained for authors and coauthors of abstracts. You will need to create a new account in the abstract submission system.
No, you do not need to update your password every time you edit your submission profile. You can proceed to save changes to your submission profile without refilling out the password section.
Your name and contact information on your CROI profile will appear as it was entered when your profile was created by you or your abstract coauthor. You may update your profile within the abstract system. See Abstract Guidelines and Submission for more information and to access the abstract system.
I am a submitting author and made a spelling error in the name of my coauthor(s). How can I update their information?
Before the submission deadline, the submitter may log in and edit coauthor details from within the abstract. After the submission deadline, contact CROIabstracts@iasusa.org for corrections to the author’s information.
I have entered the information (ie city/state/country/degree) for a co-author incorrectly. How can I change this?
Only the co-author can edit their profile information. Each co-author will receive an email once an abstract has been submitted. If the co-author’s profile information is wrong, the co-author must log in and change it.
The submitting author can make changes to the abstract submission by editing the author’s information within the abstract. See Abstract Guidelines and Submission for more information and to access the abstract system.
The abstract submitter provided the institution information for each author listed in the abstract submission. The submitter may correct the entry prior to the submission deadline. After the submission deadline, contact CROIabstracts@iasusa.org for corrections to the author’s information.

Confirmation emails are sent from email@example.com. If you have not received the email, please check your spam folder and add firstname.lastname@example.org to your safe sender list.
Once the submission process ends, abstracts immediately enter the peer review and scoring process. Therefore, no changes can be made after the submission deadline, unless changes or clarification are specifically requested by the abstract review team. Updates and new data can be included in the presentation at CROI.
Common reasons for declining an abstract include the following:
- Submission application was not complete
- Subject matter is not appropriate for CROI
- Information is not new enough
- Abstract duplicates other submissions
- Data are not included or offer inadequate/insufficient support for conclusions
- Statistical evaluation is absent or inadequate
- Format does not follow guidelines (eg, section[s] missing, more than 1 graphic, table, or figure submitted)
- Submission is poorly written overall
- Background does not summarize the hypothesis
- Methodology is inadequate or insufficient to support conclusions
- Controls are absent or inadequate
- Summary of essential results is absent or inadequate
- Submission reports clinical trial data from unplanned analysis or incomplete or ongoing studies
Abstract submissions need to describe the precise findings of the study; promise of results “to be determined” or trials in progress are not acceptable. For more information, visit the Abstract Guidelines and Submission page.
In general, CROI does not accept work that has been previously published or publicly presented, or that is scheduled to be published or presented prior to CROI. Consideration may be given to a previously presented submission if meaningful newer data or different analyses are included, or if the prior or anticipated presentation was or will be at a conference not focused on HIV-, viral hepatitis-, or SARS-CoV-2-related topics. Electronic publication ahead of print that has been peer-reviewed and made generally accessible to the public is considered publication. However, if the authors provide an explanation of new data that will be presented at CROI beyond the prepublication, the abstract will be considered for presentation. For more information, visit the Abstract Guidelines and Submission webpage.

If a presenting author is not able to attend CROI in person, can an alternate presenter present on their behalf?
If exigent circumstances prevent the designated presenting author from attending the conference in person, a coauthor or colleague must be appointed to present the abstract in person at CROI.
Please contact CROIabstracts@iasusa.org as soon as possible. If the new presenter is a coauthor, please provide their name. If the new presenter is a colleague, please provide their name, institution, city, country, and email address. The new presenter must register to attend CROI in person and disclose financial relationships with ineligible companies.
