Mayor Villarreal released a video stating that the person arrived from Guerrero to San Miguel, where he rented a house, got sick, and later died in the General Hospital of Celaya. The Secretariat of Health said he was 37 years old and had no record of chronic diseases. 

In order to prevent the importation of cases, the city will keep working on the sanitary filters in the accesses to the city to avoid importation and augmentation of COVID-19.
