Fish may get infected by both herpesvirus and retrovirus

Summary of the week

Both retrovirus and herpesvirus establish life-long diseases which are very difficult to eliminate from the body. The mechanism of the chronic disease is different in both cases. While herpesviruses remain latent in certain body locations, by expressing certain latency genes, retroviruses integrate in the host genome and are only expressed when specific cellular factors activate the proviral genome.
