[Emerging infectious agents]

Area of Science:

• Public Health
• Infectious Diseases
• Epidemiology

Background:

• The past decade has seen a rise in emerging and re-emerging infectious diseases.
• Several diseases, including SARS, MERS-CoV, avian influenza A(H5N1), Ebola virus disease, and Zika virus, have raised global health concerns due to their severity and transmission.
• These outbreaks highlight the need for robust public health systems capable of managing highly communicable and virulent diseases.

Purpose of the Study:

• To underscore the public health threat posed by emerging infectious diseases.
• To emphasize the need for enhanced surveillance and response systems.
• To inform the development of new health system organizations for managing virulent outbreaks.

Main Methods:

• Review of recent emerging and re-emerging infectious disease events.
• Analysis of disease characteristics (virulence, mortality, transmission, maternofoetal transmission).
• Examination of public health authority responses and organizational strategies.

Main Results:

• Significant increase in the occurrence of emerging/re-emerging infectious diseases.
• Identification of key pathogens (SARS, MERS-CoV, H5N1, Ebola, Zika) as major public health concerns.
• Recognition of the need for improved health system organization for rapid case identification, isolation, and management.

Conclusions:

• Emerging infectious diseases represent a substantial and ongoing threat to global public health.
• Effective management requires proactive policies, strategic planning, and adaptable health system organizations.
• Immediate isolation and adequate management protocols are crucial for controlling highly communicable and virulent diseases.
