SARS-CoV-2 in Argentina: Lockdown, mobility, and contagion

Area of Science:

• Epidemiology
• Public Health Policy
• Econometrics

Background:

• Argentina implemented one of the world's longest COVID-19 lockdowns (6 months).
• Public compliance decreased due to significant economic and social costs.
• Debate exists regarding the effectiveness of prolonged mandatory lockdowns for severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2).

Purpose of the Study:

• To analyze the relationship between mobility and COVID-19 contagion at a provincial level in Argentina.
• To model the impact of political discussions, protests, and crowd events on regional contagion.
• To evaluate the long-term effectiveness of strict lockdown measures.

Main Methods:

• Panel data modeling using fixed, random, and pooled effects.
• Analysis of provincial-level data on mobility and severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) contagion.
• Inclusion of variables representing political factors and public gatherings.

Main Results:

• Lockdown policies effectively reduced population mobility.
• Reduced mobility did not translate into a significant decrease in the rate of contagion.
• Strict lockdowns showed short-term effectiveness, but this diminished over time without complementary mitigation strategies.
• Contagion rates exhibited temporal displacement, resurging with gradual increases in mobility.

Conclusions:

• Prolonged mandatory lockdowns in Argentina were insufficient to control COVID-19 contagion.
• Sustained mobility reduction requires integrated mitigation measures beyond simple lockdown enforcement.
• Policy evaluation must consider temporal dynamics and the impact of social and political factors on disease transmission.
