We thank Mohamed Hassany and colleagues, Ahmed Negida, Tarek Sahmoud, and Khaled Elmeleegy for raising their concerns about our modelling study. We would like to reiterate that the number of confirmed cases of coronavirus disease 2019 (COVID-19) in every country worldwide (Egypt included) is an underestimate of the true burden of illness, regardless of the screening programmes in place.

To estimate the burden of coronavirus disease 2019 (COVID-19) in Egypt, Ashleigh R Tuite and colleagues1 used the same model of exported case detection used by Fraser and colleagues for the H1N1 outbreak in Mexico.2 However, Tuite and colleagues neither clarified nor verified the assumptions of this exported case-detection model.

In December, coronavirus disease 2019 (COVID-19) emerged in Wuhan, China, causing a pandemic that continues to spread globally.1 86 countries have reported cases.2 As of March 6, 2020, Egypt has reported three cases of COVID-19; however, at least 14 cases have been exported from Egypt to four countries.3 The burden of infection in Egypt, therefore, might be substantially larger than reported.

A clinically significant risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission by fomites (inanimate surfaces or objects) has been assumed on the basis of studies that have little resemblance to real-life scenarios.

“We're not just fighting a pandemic; we're fighting an infodemic,” said Tedros Adhanom Ghebreyesus, WHO's director-general, at the 2020 Munich Security Conference. Fake news, misinformation, and conspiracy theories have become prevalent in the age of social media and have skyrocketed since the beginning of the COVID-19 pandemic. This situation is extremely concerning because it undermines trust in health institutions and programmes.

As the far-reaching impacts of the coronavirus disease 2019 (COVID-19) pandemic expand to more and more countries, key questions about transmission dynamics and optimal intervention strategies remain unanswered. In particular, the age profile of susceptibility and infectivity, the frequency of super-spreading events, the amount of transmission in the household, and the contribution of asymptomatic individuals to transmission remain debated.

In December, 2019, COVID-19 was recognised as a novel respiratory disease in Wuhan, China,1 caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).2 Accurate and reliable data on SARS-CoV-2 incubation time, secondary attack rate, and transmission dynamics are key to successful containment. In late January, 2020, infection with SARS-CoV-2 was detected in Germany for the first time.

The first known case of the novel coronavirus (COVID-19) was reported in China in November 2019; in the United States, the first reported case was on January 22.* Essential stay-at-home mandates worldwide have helped mitigate the exponential growth in hospitalizations and death and have led to gradual reopenings in China,...

Social distancing is the core policy response to coronavirus disease 2019 (COVID-19). But, as federal, state and local governments begin opening businesses and relaxing shelter-in-place orders worldwide, we lack quantitative evidence on how policies in one region affect mobility and social distancing in other regions and the consequences of uncoordinated...

The Diamond Princess cruise ship was put under quarantine offshore Yokohama, Japan, after a passenger who disembarked in Hong Kong was confirmed as a coronavirus disease 2019 case. We performed whole-genome sequencing of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) directly from PCR+ clinical specimens and conducted a phylogenetic analysis...

In the absence of a vaccine, social distancing measures are one of the primary tools to reduce the transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus, which causes coronavirus disease 2019 (COVID-19). We show that social distancing following US state-level emergency declarations substantially varies by income. Using...

Following the April 16, 2020 release of the Opening Up America Again guidelines for relaxing coronavirus disease 2019 (COVID-19) social distancing policies, local leaders are concerned about future pandemic waves and lack robust strategies for tracking and suppressing transmission. Here, we present a strategy for triggering short-term shelter-in-place orders when...

Novel coronavirus (COVID-19) pneumonia has emerged as major global health threat as it continues to spread with increasing number of deaths. COVID-19 is an enveloped, single-stranded RNA coronavirus that is largely transmitted by inhalation of respiratory droplets.
