COVID-19: Look to the Future, Learn from the Past

Area of Science:

• Virology
• Epidemiology
• Public Health

Background:

• The global pandemic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is characterized by rapidly increasing confirmed cases.
• Understanding SARS-CoV-2's unique characteristics is crucial for effective disease control and management.

Purpose of the Study:

• To compare the characteristics of SARS-CoV-2 with those of SARS-CoV, MERS-CoV, and influenza.
• To provide insights into prevention and control strategies for COVID-19.

Main Methods:

• Comparative analysis of virological, etiological, epidemiological, and virulence characteristics.
• Review of existing data on SARS-CoV-2, SARS-CoV, MERS-CoV, and influenza.

Main Results:

• SARS-CoV-2 shares virological and etiological similarities with SARS-CoV and MERS-CoV.
• Epidemiologically and in terms of virulence, SARS-CoV-2 is more akin to influenza.
• High transmissibility and asymptomatic spread present significant challenges for eradication.

Conclusions:

• The findings offer a new perspective on COVID-19 disease control.
• Effective prevention and control strategies are needed to manage the ongoing pandemic.
• Long-term coexistence with SARS-CoV-2 should be considered due to its persistent nature.
