The invention provides methods and compositions that remove target genetic material from a subject by hydrodynamic delivery of an enzyme that degrades the target genetic material. The methods include delivering a solution include a nucleic acid, protein, or ribonucleoprotein to a blood vessel at a pressure sufficient to cause the material to enter cells proximal to the blood vessel. The enzyme may be Cas9 and may be provided with a guide RNA. The target genetic material may be viral genome with the guide RNA complementary to a portion of the viral genome.
