Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 0 years and older
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Study population: Children or adults presenting at the emergency departments or hospitalized at the University Hospital of Bern with any symptom compatible with an acute respiratory tract infection in whom a nasopharyngeal swab to test for respiratory viruses is performed (standard of care). Consecutive participant recruitment will be performed at the children and adult emergency departments during working hours of the study nurse.

Who may be able to join

  • Patients presenting at the emergency departments or hospitalized at Inselspital Bern university hospital with any symptom compatible with an acute respiratory tract infection in whom a nasopharyngeal swab to test for respiratory viruses is performed (standard of care)
  • Written informed consent from the trial subject has been obtained; for patients aged 0-13 years, or not able to provide informed consent, consent obtained from the legal representative; for patients between 14-18 years, written informed consent obtained from the respective patient as well as the legal representative.

Who cannot join

  • Patients unable to provide a saliva (e.g. patients with reduced level of consciousness). Children too young to be instructed to provide saliva are not excluded, but saliva won't be collected.
  • Patients with swallowing disturbances
  • Patient's lack of accountability and inability to appreciate the nature, meaning and consequences of the study and to formulate his/her own wishes correspondingly AND legal representative not available.

About this study

Official title: Comparison Between Nasopharynx and Orobuccal/Nasal Swabs or Saliva for Detection of Respiratory Viruses (ORASAMP)

The goal of this observational study is to validate the use of less invasive samples (saliva, orobuccal or nasal swabs) than nasopharyngeal swab for testing common and clinically relevant respiratory viruses in children and adults presenting to an emergency departements with symptoms compatible with respiratory tract infection. The main question it aims to answer is:

  • Is the precision of reverse transcription polymerase chain reaction (RT-PCR) for Influenzavirus A or B, respiratory syncytial virus (RSV), and Rhinovirus, on saliva, orobuccal swabs and nasal swabs comparable to the gold standard nasopharyngeal swab in a pediatric and adult population presenting with symptoms compatible with respiratory tract infection.

Among participants the following samples will be collected (nasopharyngeal swab is standard of care and not part of the study samples):

  • Saliva
  • Orobuccal swab
  • Nasal swab

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • RT-PCR in different respiratory tract samplesDiagnostic test

    RT-PCR on saliva, orrobuccal swab and nasal swab will be performed. Nasopharyngeal swab will be performed independently of the study as standard of care.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Sensitivity of RT-PCR for Influenzavirus A or B, RSV and Rhinovirus, on orobuccal or nasal swab and saliva compared to nasopharyngeal swab.

    Measured: At baseline

  2. Specificity of RT-PCR for Influenzavirus A or B, RSV and Rhinovirus, on orobuccal or nasal swab and saliva compared to nasopharyngeal swab.

    Measured: At baseline

Secondary outcomes (10)
  1. Area under the receiver operating characteristic (ROC) curve for the detection of Influenza A/B, RSV and Rhinovirus in each study sample (orobuccal or nasal swab and saliva).

    Measured: At baseline

  2. Positive agreement between viral copy number of RT-PCR for Influenzavirus A or B, RSV, and Rhinovirus, Parainfluenzavirus, Adenovirus, human Metapneumovirus in saliva, orobuccal swabs and nasal swabs compared to nasopharyngeal swabs.

    Measured: At baseline

  3. Negative agreement between viral copy number of RT-PCR for Influenzavirus A or B, RSV, and Rhinovirus, Parainfluenzavirus, Adenovirus, human Metapneumovirus in saliva, orobuccal swabs and nasal swabs compared to nasopharyngeal swabs.

    Measured: At baseline

  4. Prevalence of respiratory viruses in orobuccal, nasal or nasopharyngeal swabs and saliva.

    Measured: At baseline

  5. Sensitivity of RT-PCR for Parainfluenzavirus, Adenovirus and human Metapneumovirus in orobuccal, nasal and saliva samples.

    Measured: At baseline

  6. Specificity of RT-PCR for Parainfluenzavirus, Adenovirus and human Metapneumovirus in orobuccal, nasal and saliva samples.

    Measured: At baseline

  7. Incremental yield of virus detection in orobuccal, nasal and saliva as compared to nasopharyngeal samples.

    Measured: At baseline

  8. Co-prevalence of respiratory viruses in orobuccal, nasal or nasopharyngeal swabs and saliva.

    Measured: At baseline

  9. Association between predefined symptoms and probability for positive RT-PCR of specific viruses using different (nasopharyngeal, orobuccal, nasal, saliva) samples.

    Measured: At baseline

  10. Comparative cycling time values at the different sampling locations

    Measured: At baseline

Questions about this trial

What is this clinical trial studying?

An observational study of Respiratory Tract Infection Viral, run by Insel Gruppe AG, University Hospital Bern at 1 site in Switzerland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sensitivity of RT-PCR for Influenzavirus A or B, RSV and Rhinovirus, on orobuccal or nasal swab and saliva compared to nasopharyngeal swab. (time frame: At baseline). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Jul 2025.
