COVID-19 versus SARS: A comparative review.

Area of Science:

• Virology
• Epidemiology
• Pathogenesis

Background:

• Severe acute respiratory syndrome coronaviruses (SARS-CoV-1 and SARS-CoV-2) are genetically similar but caused global epidemics of differing scales.
• Divergence in transmission dynamics and clinical presentations between SARS-CoV-1 and SARS-CoV-2.
• Infections can affect multiple organ systems, including respiratory, cardiac, gastrointestinal, and neurological systems.

Purpose of the Study:

• To provide a comprehensive understanding of the clinical pathogenesis of SARS-CoV-1 and SARS-CoV-2.
• To discuss the evolution of COVID-19 management strategies.
• To highlight lessons learned for future pandemic preparedness.

Main Methods:

• Comparative analysis of SARS-CoV-1 and SARS-CoV-2.
• Review of clinical presentations and organ system involvement.
• Examination of evolving management strategies, therapeutics, and vaccines for COVID-19.

Main Results:

• SARS-CoV-1 and SARS-CoV-2, despite similar origins, exhibit significant differences in transmission and disease spectrum.
• COVID-19 management has evolved significantly due to accumulating knowledge and therapeutic advancements.
• The profound impact on healthcare systems underscores the need for pandemic preparedness.

Conclusions:

• A thorough understanding of viral pathogenesis is essential for effective disease management.
• Lessons from SARS-CoV-2 are critical for controlling the current pandemic and mitigating future ones.
• Preparedness and knowledge sharing are key to reducing the global impact of coronavirus outbreaks.
