In contrast, a disease that has a short duration may have a low prevalence and a high incidence.
The lower prevalence than in the 2008 study may be due to the 2009 sample being more representative of the general population.
A low prevalence of ectopic spheroids can also be observed in some cases.
This may account for the low prevalence of the illness.
It may be, however, that low prevalence among more distant relatives results in part from lower levels of ascertainment.
The lowest prevalence was seen in the northern coastal Atlantic forest.
Jordan's cultural sensitivities pose the greatest threat to the country's low prevalence.
Other populations have a lower prevalence of both the genetic mutation and the clinical disease.
Since 2004, the threat risk from these variants has been changed to "low" due to decreased prevalence.
Two Asian studies, however, report a much lower prevalence.
