Interventions

Lockdown and other social distancing measuresbehavioral

During the study period, the Chilean Ministry of Health established a five-step process for social distancing measures. These ranged from full lockdown (step 1) to almost no restrictions (step 5). Even under full lockdown, citizens were able to obtain permits for essential activities. Citizens had a maximum of two permits per week and were obtained in a virtual station of the Chilean Police Force (Carabineros de Chile).
