What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This observational study aims to measure how often cytomegalovirus (CMV) is present in the saliva of young children (up to 36 months) and staff at large childcare centers. Participants will provide a saliva sample and answer a health survey. The findings will help design future steps to understand CMV transmission and potentially reduce infection risks.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Saliva sample collection for CMV PCR testing
What this could lead to
If successful, this study could reveal how common CMV shedding is in childcare settings, informing strategies to reduce transmission and protect pregnant women.
What could go wrong
This is an early observational study, so it won't test any intervention. Results may not apply to all childcare centers, and the focus on saliva shedding may not fully capture transmission risk.
