Neonatal Infection Due to SARS-CoV-2: An Epidemiological Study in Spain.

Area of Science:

• Neonatal Medicine
• Infectious Diseases
• Epidemiology

Background:

• Coronavirus disease 2019 (COVID-19) continues to spread globally.
• Limited data exists on COVID-19 in neonates, a unique and vulnerable population.
• Understanding neonatal COVID-19 is crucial for effective public health strategies.

Purpose of the Study:

• To describe the characteristics, management, and treatment of neonatal COVID-19 cases acquired postnatally in Spain.
• To differentiate between community-acquired and hospital-acquired infections.
• To identify risk factors for severe disease in neonates.

Main Methods:

• A prospective, national epidemiological study was conducted.
• Data was collected from a National Registry supported by the Spanish Society of Neonatology.
• Included neonates with postnatal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, detailing transmission, clinical presentation, and outcomes.

Main Results:

• Forty cases were registered: 26 community-acquired and 14 nosocomial.
• Mothers and healthcare workers were primary sources of infection.
• Most neonates, including asymptomatic cases, had mild symptoms; severe cases occurred in preterm or comorbid infants.

Conclusions:

• This is the largest series of neonatal COVID-19 cases in Spain.
• Clinical manifestations were generally mild, but vigilance is necessary.
• Effective prevention, treatment, and management strategies are essential for neonatal COVID-19.
