The Blood Transfusion Service of Namibia (NamBTS) will on Sunday mark the 22nd anniversary of World Blood Donor Day.

The day will be celebrated under the global theme "One Drop of Humanity: Give Blood. Save Lives." 

The country's blood supply is currently at a critical level. The spokesperson for the Namibian Blood Transfusion Service (NamBTS), Frieda Asino-Vatilemi, says there is only enough blood to last for this week, placing the country in a crisis.
