Infectious disease emergencies: role of the infectious disease specialist
1Swedish Institute for Infectious Disease Control, Solna, Sweden. Ragnar.Norrby@smi.ki.se
Abstract:
The importance of infections for public health has become obvious during the last decades. Examples are emerging infections such as HIV/AIDS and severe acute respiratory syndrome, deliberate release of microorganisms, such as the anthrax episode in the USA, the increasing problems with organisms resistant to antimicrobial treatment, such as methicillin-resistant Staphylococcus aureus, and the threat of a new influenza pandemic with a case fatality rate similar to that in the 1918 outbreak. An effective response to infectious disease emergencies requires careful planning and establishment of resources in advance. The medical specialties involved are clinical microbiology, clinical infectious diseases and epidemiology. Clinical microbiology should include bacteriology, virology, and parasitology; the technical developments during the last 15 years have clearly erased most of the methodological differences between these branches of microbiology. New techniques such as new generations of Polymerase Chain Reaction (PCR), rapid methods for nucleic acid sequence analyses and microarrays have enabled more rapid identification of organisms and provide powerful tools in the epidemiological analysis of an outbreak. The infectious disease specialists are necessary for rapid and adequate clinical diagnoses, optimal use of antimicrobial agents and provision of facilities for containment of patients who may spread the infections. The need for isolation units became acute when many countries prepared themselves for a possible severe acute respiratory syndrome outbreak in Europe. With few exceptions, Europe still lacks epidemiological field forces, and it has been embarrassing to be obliged to call upon the Centers for Disease Control for European outbreaks. Hopefully, this will be corrected with the creation of the European Centre for Disease Prevention and Control (ECDC).
Insights
Emerging infectious diseases and antimicrobial resistance pose significant public health threats. Effective response requires advanced clinical microbiology, infectious disease expertise, and robust epidemiological surveillance, necessitating improved European infrastructure.
Area of Science:
- Public Health
- Infectious Diseases
- Clinical Microbiology
- Epidemiology
Background:
- Infectious diseases, including emerging infections (e.g., HIV/AIDS, SARS), bioterrorism (e.g., anthrax), antimicrobial resistance (e.g., MRSA), and pandemics (e.g., influenza), represent major public health challenges.
- Effective management of infectious disease emergencies necessitates proactive planning and resource allocation.
- Key medical disciplines involved include clinical microbiology, clinical infectious diseases, and epidemiology.
Purpose of the Study:
- To highlight the critical role of clinical microbiology, infectious diseases, and epidemiology in combating public health threats from infections.
- To emphasize the need for advanced diagnostic tools and specialized clinical services for managing infectious disease outbreaks.
- To underscore the importance of developing robust epidemiological surveillance and response capabilities in Europe.
Main Methods:
- Review of advancements in clinical microbiology, including new generations of Polymerase Chain Reaction (PCR), nucleic acid sequence analyses, and microarrays for rapid organism identification.
- Discussion of the essential contributions of infectious disease specialists in diagnosis, antimicrobial therapy, and patient containment.
- Assessment of the current state of epidemiological field forces in Europe and the need for enhanced infrastructure.
Main Results:
- Technological advancements have significantly improved the speed and accuracy of microbial identification and epidemiological analysis.
- Infectious disease specialists are crucial for timely clinical management and preventing disease spread.
- Europe has historically lacked sufficient epidemiological field capacity, highlighting the need for organizations like the European Centre for Disease Prevention and Control (ECDC).
Conclusions:
- Integrated efforts in clinical microbiology, infectious diseases, and epidemiology, supported by advanced technology, are vital for public health protection against infectious threats.
- Strengthening European epidemiological surveillance and response mechanisms is essential to address current and future infectious disease emergencies.
- Investment in specialized facilities, such as isolation units, and trained personnel is critical for preparedness.
