A latent infection may become productive in response to changes in the host's environmental conditions or health; the provirus may be activated and begin transcription of its viral genome.

Epstein-Barr virus encoded latent infection membrane protein-1 ( LMP1 ) can interact with this and several other members of the TRAF family, which may be essential for the oncogenic effects of LMP1.
33.
Subsequent studies employing only serological techniques that do not distinguish active from latent infection have produced mixed results : most, but not all, have found an association between CFS and HHV-6 infection.
34.
Some evidence suggests latent infection may subtly influence a range of human behaviors and tendencies, and infection may alter the susceptibility to or intensity of a number of psychiatric, or neurological disorders.
35.
There are 5 transcripts identified during latent infection of VZV . Open reading frames ( ORFs ) 21, 29, 62, 63, and 66 are all expressed with 62 and 63 being the most abundant.
36.
It's still unclear whether these problems result chiefly from a flareup of a latent infection or, as may happen with arthritis, from an auto-immune attack in which the body attacks tissues harboring the spirochete.
37.
The National Institute of Allergies and Infectious Diseases estimates that 10 million to 15 million U . S . residents have such latent infections, and about one in 10 of them will eventually develop active TB.
38.
Some drugs, including rheumatoid arthritis drugs that work by blocking tumor necrosis factor-alpha ( an inflammation-causingcytokine ), raise the risk of activating a latent infection due to the importance of this cytokine in the immune defense against TB.
39.
They now believe they have uncovered the answer-- and, in the process, a radically new view that contradicts the conventional profile of HIV as a chronic or latent infection that is activated after a long period of dormancy.
40.
The reason appears to be that a campaign against the disease focused on treating new, active cases instead of eliminating latent infections, Elvin Geng, a medical student at Columbia University, reported in Thursday's New England Journal of Medicine.
