A direct estimate of the putative latent period could be made by comparing quantitatively the age distribution for positive HIV tests with the age distribution for deaths from HIV disease.
There is no indication of the latent period of about a decade followed by some years of living with AIDS that is a staple of HIV/AIDS theory; indeed, these data appear to be a disproof of the hypothesis of a latent period.
In this research lines were clustered by latent period infection type, pustule size, pustule density.
For any rate of growth, assuming different latent periods changed peak absenteeism by <1% for most scenarios; assuming longer infectious periods increased peak absenteeism by <3%.
Although our study suggested that women with high relative delivered doses (RDDs) of PCE-contaminated drinking water have an increased risk of breast cancer, firm conclusions were limited by the small proportion of exposed subjects, particularly when long latent periods were considered.
The right Dix-Hallpike provoked a fine right-beating and down-beating nystagmus that had a torsional (clockwise) component; there was no latent period before the nystagmus appeared, and repeat positioning did not result in any fatigue of the response.
The initial conditions for the case that the epidemic is started by one infected index case entering the population at the beginning of his latent period are given by
To estimate the duration of the latent period and the infectious period, and the probability of transmission of primary pneumonic plague, data describing cases and transmission events were sought from well-documented outbreaks.
Again, considering that we have made assumptions that favor donor screening--that the test has an exponentially distributed window period that detects infection after 3 days on average, that donor screening detects the attack after the first donor tests positive, that there is no latent period from infection through infectiousness, and that a postattack epidemic grows exponentially--donor screening as a method of attack detection does not seem competitive with simple observation of symptomatic casepatients.
1) It tends to progress slowly and fluctuates between active and latent periods.
Long latent periods may separate these attacks, which can be precipitated by drugs, infections, alcohol consumption and dieting.
