“…It is generally considered that the main mode of transmission of COVID-19 is through contact and in the form of droplets [8].The experimental results show that household masks have some filtration capacity in the relevant droplet size range, as well as efficacy in blocking droplets and particles from the wearer [9].…”

Background/Purpose The outbreak of corona virus disease 2019 (COVID-19) has become a worldwide threat to public health. The purpose of this study is to analyze the impact of COVID-19 epidemic on outpatient visits of common respiratory diseases. Methods Through statistics and comparing the data with the same period last year,we present the changes of outpatient visits of 14 common respiratory diseases in an upper first-class hospital in China from January to May,2020. Results From January to May,2020, the number of outpatient visits of most common respiratory diseases fell below the previous year,and total number of outpatient visits of 14 common respiratory diseases decreased by 58.07% year-on-year. Bronchitis, pneumonia, cough, acute upper respiratory infection and bronchiectasis infection are in our top 5 drop list,decreased by 76.79%,71.03%,66.51%56.87% and 56.31% respectively. Conclusion COVID-19 epidemic had a strong influence on the outpatient visits of common respiratory diseases, particularly for infectious diseases.

During the COVID-19 pandemic, incidence rates for dental diseases will continue unabated. However, the intent to prevent the spread of this lethal respiratory disease will likely lead to reduced treatment access due to restrictions on population movements. These changes have the potential to increase dental-related emergency department visits and subsequently contribute to greater viral transmission. Moreover, dentists experience unique challenges with preventing transmission due to frequent aerosol-producing procedures. This paper presents reviews and protocols implemented by directors and residents at the Dental College of Georgia to manage a dental emergency clinic during the COVID-19 pandemic. The methods presented include committee-based prioritization of dental patients, a multilayered screening process, team rotations with social and temporal spacing, and modified treatment room protocols. These efforts aid in the reduction of viral transmission, conservation of personal protective equipment, and expand provider availability. These protocols transcend a university and hospital-based models and are applicable to private and corporate models.

“…Wearing a surgical face mask reduced coronavirus titres, as determined by RT‐PCR, both in droplets and in aerosols; while for influenza virus, masks decreased only viral titres in droplets, and for rhinovirus, the mask had no effect on virus excretion (Leung et al . , 2020).…”

Summary What was initially a lung infection epidemic in the metropolitan area of Wuhan followed by a now contained extension to mainland China has now spread to all continents as a major pandemic with current hotspots in Europe and the USA. This minireview is an update of an earlier report on this novel coronavirus infection (Brüssow, 2020, Microb Biotech 13, 607). I am now summarizing the research literature published between end of February to mid‐April 2020.
