Clinical latent phase

Diller describes three main phases associated with phosgene induced lung injury as the initial reflex syndrome, the clinical latent phase and the clinical oedema phase. ... 

Latency Delayed onset of disease with few or no clinical signs during the latent phase may delay recognition that infection has already occurred. 

Clinical Course of Radiation Sickness. The three syndromes described follow a similar clinical pattern that can be divided into three phases an initial or prodromal phase occurring during the first few hours after exposure a latent phase, which becomes shorter with increasing dose and the manifest phase of clinical illness. 

Psychosis or mania Antidepressants can precipitate manic episodes in bipolar disorder patients during the depressed phase of their illness and may activate latent psychosis in other susceptible individuals. The sustained-release formulation of bupropion is expected to pose similar risks. There were no reports of activation of psychosis or mania in clinical trials conducted in nondepressed smokers.
