Sentence examples for endemic stability from inspiring English sources

The impact on endemic stability is an important consideration for the design of vaccine implementation strategies.

This phenomenon has been termed as endemic stability [18].

This is due to the phenomenon of endemic stability, which in our model is attributed to the dynamics of infection and immunity as follows.

These results mirror those found more generally for the range of infectious diseases in which endemic stability is predicted to occur as well as in simpler models for malaria immunity [18], [19], [25] [27].

Thus the acquisition and loss of immunity alone can result in a pattern of "endemic stability" as defined by Coleman et al. [19] without additional need to invoke an increase in the severity of disease with age.

More recently, Coleman et al. [19] noted that this effect, termed "endemic stability" in early veterinary research, would exist for any infectious disease in which two conditions were met 1) disease is more likely (or more severe) in older age-groups and 2) following an initial infection there is a reduced probability that future infections will occur or will result in disease.

Various age-structured epidemic models have been investigated by many authors, and a number of papers have been published on finding the threshold conditions for the disease to become endemic, describing the stability of steady-state solutions, and analyzing the global behavior of these age-structured epidemic models (see [4 7]).
