At the Olimpiada mine, owned by the gold mining company Polyus, 866 cases of COVID-19 were identified. The disease spreads rapidly among shift workers. A pass regime has been introduced at the plant: employees are allowed to work at the plant only after receiving a negative COVID-19 test result. The military came to the aid of the authorities and threw specialists and equipment to the north of the region. A mobile hospital for 400 patients has been deployed by the region's forces.
