    Abstract

    We identified seasonal human coronaviruses, influenza viruses and rhinoviruses in exhaled breath and coughs of children and adults with acute respiratory illness. Surgical face masks significantly reduced detection of influenza virus RNA in respiratory droplets and coronavirus RNA in aerosols, with a trend toward reduced detection of coronavirus RNA in respiratory droplets. Our results indicate that surgical face masks could prevent transmission of human coronaviruses and influenza viruses from symptomatic individuals.

    • Rational use of face masks in the COVID-19 pandemic Shuo Feng † Chen Shen † Nan Xia † Wei Song Mengzhen Fan Benjamin J Cowling Show footnotes Published:March 20, 2020DOI:https://doi.org/10.1016/S2213-2600(20)30134-X Since the outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that caused coronavirus disease 2019 (COVID-19), the use of face masks has become ubiquitous in China and other Asian countries such as South Korea and Japan. Some provinces and municipalities in China have enforced compulsory face mask policies in public areas; however, China's national guideline has adopted a risk-based approach in offering recommendations for using face masks among health-care workers and the general public. We compared face mask use recommendations by different health authorities (panel).

    • The world needs mass at-home serological testing for antibodies elicited by SARS-CoV-2, and rapid and frequent point-of-care testing for the presence of the virus’ RNA in selected populations. How did we end up here? Two ways. Gradually, then suddenly. Ernest Hemingway’s passage is a fitting description for humanity’s perception of the exponential growth of COVID-19 cases and deaths (Fig. 1). The worldwide spread of a highly infectious pathogen was only a matter of time, as long warned by many epidemiologists, public health experts, and influential and prominent voices, such as Bill Gates. Yet most of the world was unprepared for such a pandemic; in fact, most Western countries (prominently the United States1) fumbled their response for weeks. Singapore, Hong Kong and Taiwan have shown the world that, to contain the propagation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), governments need to quickly implement aggressive testing (by detecting the viral RNA through polymerase chain reaction (PCR)), the isolation of those infected and the tracing and quarantining of their contacts, while educating their citizens about the need for physical distancing and basic public health measures (in particular, frequent hand-washing and staying at home if feeling unwell).
