Invasive group A Streptococcus infection (Streptococcus pyogenes): Current situation in Spain.

Area of Science:

• Microbiology
• Infectious Diseases
• Epidemiology

Background:

• Group A Streptococcus (GAS), or *S. pyogenes*, is a virulent Gram-positive bacterium.
• GAS causes pharyngitis but can lead to severe invasive diseases (iGAS) like necrotizing fasciitis and toxic shock syndrome.
• While iGAS has declined in developed nations, recent data suggests a potential, though inconsistent, increase.

Purpose of the Study:

• To address questions regarding the current situation of invasive GAS infections in Spain.
• To provide expert insights into the epidemiology and clinical aspects of iGAS disease.
• To inform healthcare professionals about the evolving landscape of GAS infections.

Main Methods:

• Expert consensus and review of available data on invasive GAS infections.
• Analysis of trends and clinical presentations of iGAS in Spain.
• Collaborative response formulation by a committee of specialists.

Main Results:

• The study highlights the dual nature of GAS, ranging from benign pharyngitis to life-threatening iGAS.
• Discussion addresses the historical decline and potential recent resurgence of iGAS, with a focus on Spain.
• Expert insights clarify the current understanding and challenges in managing iGAS.

Conclusions:

• Invasive GAS disease remains a significant public health concern despite historical declines.
• Accurate and consistent data collection is crucial for monitoring iGAS trends.
• Continued vigilance and expert collaboration are essential for managing and preventing severe GAS infections.
