T88 |
0-70 |
Sentence |
denotes |
In this study, we define virulence as the capacity to cause a disease. |
T89 |
71-257 |
Sentence |
denotes |
In order to measure it, we utilize a set of parameters that uniformly increase the rate or probability of causing symptomatic disease or the severity of those symptoms (including death). |
T90 |
258-558 |
Sentence |
denotes |
Our definition is more comprehensive than many other models of parasite virulence (e.g., [4,13]), which tend to focus on a single aspect of the natural history of disease associated with harm to a host (e.g., the fitness consequences of an infection on the host population or the case fatality rate). |
T91 |
559-810 |
Sentence |
denotes |
Instead of having to justify a definition built around a single term (e.g., the term associated with fatality), we took a collective approach to defining virulence through all terms that foment the viral-induced onset of symptomatic disease and death. |
T92 |
811-978 |
Sentence |
denotes |
This definition allows for the reality of pleiotropic effects in viral pathogens, where adaptations can have multiple effects on the natural history of disease [2,33]. |
T93 |
979-1084 |
Sentence |
denotes |
Our definition of virulence emphasizes terms that influence host wellness and/or are symptoms of disease. |
T94 |
1085-1259 |
Sentence |
denotes |
The iteration of virulence used in this study also undermines the potential for overly weighting only one or a small number of parameters under a large umbrella of virulence. |
T95 |
1260-1567 |
Sentence |
denotes |
Because so many varying definitions exist for virulence, we have also performed calculations according to a different definition of virulence, one that exclusively considers terms that have a detrimental direct effect on the host and neither of the terms that reflect symptoms of severe disease (𝜎a and 𝜎I). |
T96 |
1568-1631 |
Sentence |
denotes |
These calculations can be found in the Supplementary Materials. |
