The present invention provides a non-woven protective clothing against blood and viruses, which includes: a non-woven fabric layer, which has two surfaces; and a high moisture-permeable waterproof layer, which is a porous film and is laminated to one of the surfaces of the non-woven fabric layer; and an elastic pore filling layer, which is a hydrophilic polyurethane and is coated or printed onto the surface of the high moisture-permeable waterproof layer, wherein the thickness of the elastic pore filling layer is thinner than that of the high moisture-permeable waterproof layer. The non-woven protective clothing against blood and viruses is characterized in that the synthetic blood permeability thereof can withstand a pressure of 2.0 psi for one minute, and the Phi-X174 bacteriophage penetrability thereof can withstand a pressure of 2.0 psi for one minute.
