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 1 month to 10 years
  • All sexes
  • Healthy volunteers accepted
  • Child

Study population: The prevalance of clinial diagnosed pneumonia and invasive diseases in Hainan Province will be mainly collected from the electronic medical record (EMR) database of selected hospitals and face-to-face questionnaire survey, in the fever clinics and pediatric wards of selected hospitals. A control group of healthy community children will be systematically sampled from residents from the same area as the cases and frequency-matched by age group.

Who may be able to join

  • 1. Case group: patients from fever clinics and pediatric wards
  • Patients with at least one of the following will be clinically diagnosed with pneumonia and recommended for NP/OP, blood cultures, or induced sputum as clinically indicated (TB only or if performed routinely by the clinician), bronchoalveolar lavage fluid (BALF , according to clinical requirements), pleural effusion (according to clinical requirements), and chest X-ray examination:
  • Shortness of breath ( children <2 months, respiratory rate ≥60 breaths/min; children ≥2 months to <12 months, respiratory rate ≥50 breaths/min; children ≥12 months to < 60 months, respiratory rate ≥40 breaths/min; Children ≥ 60 months to < 120 months, respiratory rate > 24 breaths/minute )
  • Rales on lung auscultation
  • Respiratory symptoms and fever ( axillary temperature ≥ 37.5 ℃ or rectal temperature ≥ 38 ℃ )
  • 2. Control group The control group will be randomly selected from the community and frequency-matched 1:1 with the case group according to age group, sex and city.

Who cannot join

  • 1. Hospitalized within the first 14 days, or discharged as a case group within the first 30 days, and lived outside the research center area ;
  • 2. People who affect the research results: patients cannot keep samples or the amount of samples is not enough for testing;
  • 3. Can't cooperate well;
  • 4. The researcher judges that it is not suitable to be included in this study .

About this study

This study intends to screen children under the age of 10 for respiratory pathogens, Streptococcus pneumoniae, and serotyping in three representative cities in Hainan province: Haikou, Wanning, and Baisha, in order to provide a foundation for the subsequent promotion of Streptococcus pneumoniae vaccines.

Read the detailed description

The purpose of this multi-center epidemiological study was to determine the carrier status of clinically diagnosed pneumonia, pathogen spectrum of clinically diagnosed pneumonia, serotype distribution, and drug resistance profile of Streptococcus pneumoniae in sick children from hospitals and healthy children from the community.

What is being measured

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

  1. Prevalence of pneumococcus

    Estimate the prevalence of pneumococcus among children aged<10 years old hospitalized with clinical diagnosed pneumonia, in children seen at outpatient clinics, and among healthy children in the community in Hainan

    Measured: 1 day

  2. Correaltion index of high load (>6.9 log10 copies/ml) pneumococcus

    Estimate the association with disease (i.e., case-control status) of high load (>6.9 log10 copies/ml) pneumococcus among outpatient or hospitalized patients with clinical diagnosed pneumonia in children aged<10 years old and among healthy children in the community in Hainan

    Measured: 1 day

  3. Correaltion index of disease status of infection with different pathogens

    Estimate the association with disease status of infection with pathogens of interest (or combination of pathogens) among children aged<10 years old hospitalized with clinical diagnosed pneumonia compared to healthy children in the community in Hainan. The study is designed to be the case-control study

    Measured: 1 day

Secondary outcomes (2)
  1. Estimate the proportions of srotypes in patients and healthy children

    Estimate the pneumococcal serotype distribution in children aged<10 years old with clinically diagnosed pneumonia carrying pneumococcus in Hainan.

    Measured: 1 day

  2. Describe the resistance proportion of antibiotics in different region in Hainan

    Describe the antimicrobial resistance patterns in children aged<10 years old with clinically diagnosed pneumonia carrying pneumococcus in Hainan.

    Measured: 1 day

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?

Prevalence of pneumococcus (time frame: 1 day). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05912010, which also lists 7 linked publications.

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 8 Aug 2025.
