South Cotabato Governor Reynaldo Tamayo Jr. on Monday issued Executive Order (EO) No. 01 Series of 2022 that instructed the one city and 10 municipal government units in the province to require RT PCR results taken within three days for the travelers from high-risk countries and areas in the Philippines within Alert Level 3 or higher categories.
