Is blood donation a rescue during the epidemic?

In the period of fighting the epidemic, blood donation without compensation is the first line to support the fight against the epidemic. During the epidemic period, in order to ensure the absolute safety of blood, there is a higher requirement for blood donors' travel cards, requiring that blood donors have never been to high-risk areas in the epidemic within 28 days. No contact with high-risk groups in COVID-19 for 28 days. Besides travel itinerary, you must also show the green health code.
