T83 |
0-130 |
Sentence |
denotes |
To estimate the effective daily reproduction ratio, we initially get the time-dependent contact rate c(t) and δI(t) as Fig. 1 (a). |
T84 |
131-279 |
Sentence |
denotes |
Using the discrete values of contact rate c(t) and diagnose rate δI(t), we can calculate the effective daily reproduction ratio, shown in Fig. 1(b). |
T85 |
280-497 |
Sentence |
denotes |
It follows that under the strict prevention and control measures, the effective daily reproduction ratio Rd(t) has been less than 1 since January 26th, 2020, that is, the number of new infections has begun to decline. |
T86 |
498-764 |
Sentence |
denotes |
Note that the effective daily reproduction ratio declined from January 23rd, 2020 to January 25th, 2020, as a combination of the restrictive measures, including the lock-down of Wuhan, contact tracing followed by quarantine and isolation, that have been implemented. |
T87 |
765-995 |
Sentence |
denotes |
In practice, this time variation of the contact and diagnose rates leads to sub-exponential rather than exponential growth dynamics, and hence provides better estimates of epidemic size compared to fully exponential growth models. |
T88 |
996-1139 |
Sentence |
denotes |
We refer to (Pell, Kuang, Viboud, & Chowell, 2018; Smirnova & Chowell, 2017) for earlier studies on sub-exponential growth of modern epidemics. |
T89 |
1140-1312 |
Sentence |
denotes |
Fig. 1 (A) Time-dependent contact rate c(t) and diagnose rate δI(t); (B) Effective daily reproduction ratio Rd(t), declining due to reduction of c(t) and increase of δI(t). |
