Insights
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in infants under 90 days is not rare and presents differently based on age. This study highlights varied clinical features and outcomes in neonatal and post-neonatal groups.
Area of Science:
- Pediatrics
- Infectious Diseases
- Public Health
Background:
- Limited data exist on SARS-CoV-2 (COVID-19) in infants under 90 days.
- Existing reports on presentation and outcomes are conflicting.
Purpose of the Study:
- To investigate the clinical characteristics and outcomes of SARS-CoV-2 infection in infants up to 90 days old.
- To analyze variations in presentation based on age groups within the first 90 days of life.
Main Methods:
- An ambispective cohort study was conducted using data from Saudi Arabia's Health Electronic Surveillance Network.
- Infants under 90 days with positive SARS-CoV-2 RT-PCR tests were categorized into early neonatal (0-6 days), late neonatal (7-27 days), and post-neonatal (28-90 days) groups.
- Clinical data and outcomes were collected retrospectively from parents.
Main Results:
- Out of 1,793 infants, 898 were included. Infants in the early neonatal group often lacked infection symptoms (tested due to maternal positivity).
- Fever and respiratory symptoms were common in late neonatal and post-neonatal groups.
- Hospitalization was highest in the early neonatal group (80%), with an overall mortality of 1.6%.
Conclusions:
- SARS-CoV-2 infection in infants under 90 days may be more common than previously thought.
- Clinical presentation of SARS-CoV-2 infection in infants varies significantly with age at diagnosis.
Background:
Data on SARS-CoV-2 in infants ≤ 90 days are limited with conflicting reports regarding its presentation and outcomes.
Methods:
We conducted an ambispective cohort study using prospectively collected Health Electronic Surveillance Network Database by the Ministry of Health, Saudi Arabia. Infants of ≤ 90 days of age who had a positive RT-PCR test for SARS-CoV-2 virus were included. Patients were divided in Early neonatal (0-6 days), late neonatal (7-27 days), and post- neonatal (28-90 days) groups and were compared for clinical characteristics and outcomes by contacting parents and collecting information retrospectively.
Results:
Of 1,793 infants, 898 infants were included for analysis. Most infants in the early neonatal group had no features of infection (tested based on maternal positivity), whereas most infants in the late and post- neonatal groups were tested because of clinical features of infection. Fever and respiratory signs were the most common presenting feature in the late and post-neonatal groups. Hospitalization was higher in the early neonatal group (80%), compared to the two other groups. The overall mortality in the cohort was 1.6%.
Conclusion:
SARS-CoV-2 infection in infants ≤ 90 days might not be as rare as previously reported. The clinical presentation varies based on age at positive RT-PCR result.

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
