Sentence examples for sustained circulation of from inspiring English sources
In fact, a high level of perceived risk of infection at the beginning of the pandemic leads the simulated population to adopt the altered behavior (as in the presence of a well sustained circulation of the virus) resulting in a growth rate of the epidemic lower than what would have been observed in a population adopting the normal behavior.
This grouping demonstrates sustained circulation of DENV-2 strains in Africa for decades.
On the other hand, addition or removal of a glycosylation site may generate virus variants that evade the host immune system, including the response generated by vaccination, and maintain a sustained circulation of the virus within the human population [ 52].
Sustained circulation of contemporary clades of both viruses for decades and their global dissemination demonstrated that switching of the predominant genetic group did not arise through the emergence of novel lineages each respiratory season, but through the fluctuating circulation frequencies of pre-existing lineages which undergo proliferative and eclipse phases.
Sustained circulation of subtype H5 and H7 influenza viruses in terrestrial poultry often selects for viruses with a shorter neuraminidase stalk.
Since then, the virus has sustained circulation among local swine herds, raising concerns about the potential for genetic evolution of the virus and possible retransmission back to humans of variants with increased virulence.
