Estimation of the effective reproductive number R t is important for detecting changes in
disease transmission over time. During the Coronavirus Disease 2019 (COVID-19) …

Background: Interventions are now in place worldwide to reduce transmission of the novel
coronavirus. Assessing temporal variations in transmission in different countries is essential …

Accurate estimation of the parameters characterising infectious disease transmission is vital
for optimising control interventions during epidemics. A valuable metric for assessing the …

In late 2022, China transitioned from a strict 'zero-COVID'policy to rapidly abandoning nearly
all interventions and data reporting. This raised great concern about the presumably-rapid …

Background: Since December 29, 2019, pneumonia infection with 2019-nCoV has rapidly
spread out from Wuhan, Hubei Province, China to most others provinces and other counties …

The large-scale evolution of the SARS-CoV-2 virus has been marked by rapid turnover of
genetic clades. New variants show intrinsic changes, notably increased transmissibility, and …

The role of asymptomatic carriers in transmission poses challenges for control of the COVID-
19 pandemic. Study of asymptomatic transmission and implications for surveillance and …

Rationale Several studies have estimated basic production number of novel coronavirus
pneumonia (NCP). However, the time-varying transmission dynamics of NCP during the …

We characterized> 150 countries' resilience to COVID-19 as the nationwide decay rate of
daily cases or deaths from peak levels. Resilience to COVID-19 varies by a factor of~ 40 …

A novel coronavirus (SARS-CoV-2) emerged as a global threat in December 2019. As the
epidemic progresses, disease modellers continue to focus on estimating the basic …
