T123 0-31 Sentence denotes Our study has some limitations.
T124 32-110 Sentence denotes Firstly, the SEIR model was set up based on a number of necessary assumptions.
T125 111-225 Sentence denotes For example, we assumed that no super-spreaders exist in the model, but there is currently no supportive evidence.
T126 226-358 Sentence denotes Secondly, the accuracy of the estimation model depends largely on the accuracy of the parameters it used, such as incubation period.
T127 359-472 Sentence denotes With more precise parameters obtained as the epidemic progresses, our estimation model will also be more precise.
T128 473-593 Sentence denotes Our estimates of the reproductive number from 3.1 to 0.5 are based on previous studies and experience from SARS control.
T129 594-705 Sentence denotes However, this measure may change substantially over the course of this epidemic and as additional data arrives.
T130 706-823 Sentence denotes Besides, using a fixed Rt value in each phase may incur potential bias because Rt is essentially a dynamic parameter.
T131 824-909 Sentence denotes Thirdly, these estimated data may not be sustained if unforeseeable factors occurred.
T132 910-1041 Sentence denotes For example, if some infections were caused by multiple exposures to animals, these estimates will be exposed to a big uncertainty.
T133 1042-1215 Sentence denotes Fourthly, the epidemic trend shows great difference between Wuhan and Hubei Province and regions in mainland China outside Hubei Province according to the NHC reported data.
T134 1216-1332 Sentence denotes It is thus inappropriate to generalize the estimations in Wuhan to regions in mainland China outside Hubei Province.
T135 1333-1463 Sentence denotes The dynamics model for the other locations in mainland China remains to be developed and specific parameters need to be redefined.
T136 1464-1533 Sentence denotes Lastly, we do not provide model fit information in the current study.
T137 1534-1618 Sentence denotes SEIR model is a prediction model forecasting the number of infections in the future.
T138 1619-1764 Sentence denotes The data corresponding to actual situation in the future cannot be determined and this makes model fitting almost impossible during the outbreak.
T139 1765-1939 Sentence denotes We would carry out model fitting according to the real data in pace with more information and knowledge about the characteristics of COVID-19 and the epidemics in the future.
