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.

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Sputum Studies II: Culture and Sensitivity

Description
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,...
Socioemotional Development during Infancy01:30

Socioemotional Development during Infancy

Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.

Coronavirus01:29

Coronavirus

Coronaviruses, including the severe acute respiratory syndrome coronavirus (SARS-CoV), are enveloped viruses characterized by their single-stranded, positive-sense RNA genome and helical nucleocapsid structure. The hallmark of these viruses is their club-shaped spike (S) glycoproteins that protrude from the viral envelope, facilitating attachment to host cells. Typically, coronaviruses infect the upper respiratory tract, often causing mild or asymptomatic disease. However, certain strains like...

Respiratory Syncytial Virus Disease

Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
