The world is now dealing with a different type of SARS-CoV-2 than the one that emerged in China almost a year ago.

Abstract. Background. Despite the availability of published data on 4 pandemics that have occurred over the past 120 years, there is little modern information o

The key historical question here is not whether or not masks were useless. The broader, more troubling historical pattern is clear: the problem of public trust in public health.

We provide a simple model of COVID-19 transmission at workplaces, events, and other settings. We use data from reported single-event, short-duration outbreaks to estimate the transmission rate, number of contacts, and turnover at events. We use these to predict how many new infections are expected to occur at various events given the presence of a single infectious individual. We then determine which types of interventions will be the most effective in reducing the number of infections: reducing transmission rates (such as with masks), social distancing (reducing the number of people in con...

This report describes COVID-19 incidence in Kansas counties with and without mask mandates.

Background: Hong Kong was one of the first locations outside of mainland China to identify COVID-19 cases in January 2020. We assessed the impact of various public health measures on transmission.Methods: We analysed data on all COVID-19 cases and publi...

A study of 246 individuals with seasonal respiratory virus infections randomized to wear or not wear a surgical face mask showed that masks can significantly reduce detection of coronavirus and influenza virus in exhaled breath and may help interrupt virus transmission.

There were 3 influenza pandemics in the 20th century, and there has been 1 so far in the 21st century. Local, national, and international health autho...

Most Western elites are telegraphing the message that we will be forced to cover our humanity with cheap face masks indefinitely. They are mandating that even two-year-olds must wear masks. The long-term effects on the lungs, emotional and behavioral problems, and development of infants and toddlers is enormous. For such an unconstitutional invasion of personal […]

Observational evidence suggests that mask wearing mitigates SARS-CoV-2 transmission. It is uncertain if this observed association arises through protection of uninfected wearers (protective effect)...

Respiratory infections occur through the transmission of virus-containing droplets (>5 to 10 µm) and aerosols (≤5 µm) exhaled from infected individuals during breathing, speaking, coughing, and sneezing. Traditional respiratory disease control measures are designed to reduce transmission by droplets produced in the sneezes and coughs of infected individuals. However, a large proportion of the spread of coronavirus disease 2019 (COVID-19) appears to be occurring through airborne transmission of aerosols produced by asymptomatic individuals during breathing and speaking ([ 1 ][1]—[ 3 ][2]).
