Genetic virus
A genetic virus was a type of virus relating to DNA.

A deadly genetic virus was used by The Albino to kill Kang's son, Dax, as well as the sons of Kor and Koloth. This lead these Klingons and Curzon Dax, the namesake of Kang's son, to swear a blood oath to cut out the Albino's heart. ()

In 2374, The Doctor discovered a second DNA pattern in Tom Paris's nucleotide structure and reasoned that it might be a genetic virus. ()
