T243 |
0-167 |
Sentence |
denotes |
There remain important unknowns about COVID-19 that give rise to additional limitations for modelling efforts; immunity and asymptomatic transmission are two of these. |
T244 |
168-393 |
Sentence |
denotes |
We have included pre-symptomatic transmission but we have not explicitly modelled asymptomatic individuals, who may have few or no symptoms but nonetheless be transmitting, and who may or may not be building lasting immunity. |
T245 |
394-521 |
Sentence |
denotes |
Recent work suggests that both pre- and asymptomatic individuals may be contributing considerably to transmission [27, 28, 44]. |
T246 |
522-669 |
Sentence |
denotes |
We have indirectly approached this uncertainty, exploring variable underestimation fractions and duration of the incubation and infectious periods. |
T247 |
670-758 |
Sentence |
denotes |
A wide range for underestimation and duration is consistent with the reported case data. |
T248 |
759-988 |
Sentence |
denotes |
Our conclusion about the impact of distancing measures appears to be robust to these uncertainties, although the basic reproductive number and the model prevalence vary according to assumptions about underestimation and duration. |
T249 |
989-1217 |
Sentence |
denotes |
Model predictions for the peak timing and size of prevalence without strong public health interventions will depend strongly on the dynamics of immunity, including the numbers of asymptomatic individuals and their immunity [12]. |
