Taiwan's Successful COVID-19 Mitigation and Containment Strategy: Achieving Quasi Population Immunity

Area of Science:

• Epidemiology
• Public Health
• Infectious Disease Management

Background:

• The COVID-19 pandemic posed a significant threat globally, with predictions of widespread imported cases in Taiwan.
• Taiwan's proximity to China and travel during Chinese New Year presented a high-risk scenario for disease importation.

Purpose of the Study:

• To describe Taiwan's successful strategy in controlling COVID-19 without imposing economic shutdowns.
• To highlight the public health principles and interventions that led to disease control.

Main Methods:

• Implementation of non-pharmaceutical interventions such as widespread public masking and social distancing.
• Early and aggressive identification, isolation, and contact tracing of potential COVID-19 cases.
• Leveraging established public health principles to achieve "quasi population immunity".

Main Results:

• As of September 2, 2020, Taiwan reported 489 cases and 7 deaths among its population of over 23.8 million.
• Achieved 135 consecutive days (over 4 months) with no locally acquired COVID-19 cases.
• Demonstrated effective control of COVID-19 transmission without necessitating a nationwide economic shutdown.

Conclusions:

• Taiwan's integrated public health strategy serves as an effective model for managing COVID-19.
• The successful containment of COVID-19 highlights the importance of non-pharmaceutical interventions and robust public health infrastructure.
• This approach offers valuable insights for managing future emerging infectious diseases.
