Insights

Pediatricians in Greece show high knowledge of Respiratory Syncytial Virus (RSV) and vaccine confidence. Targeted education on nirsevimab is needed for optimal implementation of new RSV prevention tools.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Public Health

Background:

  • Respiratory syncytial virus (RSV) is a major cause of severe infant respiratory infections.
  • Novel immunoprophylaxis like maternal vaccination (RSVpreF) and monoclonal antibodies (nirsevimab) offer significant advancements in RSV prevention.
  • Pediatrician awareness and readiness are crucial for the successful integration of these new strategies.

Purpose of the Study:

  • To assess the knowledge, attitudes, and practices of pediatricians in Crete, Greece, regarding RSV infection and new prevention tools.
  • To identify potential barriers and facilitators for implementing novel RSV immunoprophylaxis strategies in clinical practice.

Main Methods:

  • A cross-sectional study utilizing a structured electronic questionnaire.
  • Survey distributed to board-certified pediatricians and pediatric residents in Crete between April and July 2025.
  • Analysis of responses from 169 participants.

Main Results:

  • High overall knowledge of RSV (mean score 89.6%) and strong positive attitudes toward vaccination were reported.
  • Specific knowledge gaps were identified concerning nirsevimab availability, updated recommendations, and differentiation from palivizumab.
  • A majority of pediatricians (78.6%) felt adequately informed about RSV.

Conclusions:

  • Pediatricians in Crete demonstrate a strong foundation for adopting new RSV prevention strategies.
  • Targeted educational initiatives focusing on nirsevimab are essential for consistent and equitable implementation.
  • Findings offer valuable insights for national RSV prevention planning in Greece and similar regions.

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...
Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

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...
