“…As COVID-19 has a significant different transmission profile from that of SARS and MERS [ 25 ], and surgical masks may perform differently from N95 masks, this type of pooled data and analysis may not help us to understand the utility of N95 masks in healthcare settings in the current COVID-19 pandemic. Including those cited in the above systematic review, we reviewed several observational studies that reported rates of infection in healthcare workers (either with or without wearing N95 masks) in close contact with COVID-19 patients in hospital settings [ [26] , [27] , [28] , [29] ]. Collectively, these studies reported COVID-19 infections in 132 of 4670 (2.83 %) healthcare workers who did not wear N95 masks, mostly during early stages of the pandemic and before the diagnosis was confirmed in the patients they were caring, and in 1 of 1636 (0.06 %) healthcare workers who did wear N95 masks as a part of the enhanced precaution.…”

Objectives Heightened anxiety among dental healthcare professionals (DHPs) during the COVID-19 pandemic stems from uncertainties about the effectiveness of personal protective equipment (PPE) against dental aerosols and risk levels of asymptomatic patients. Our objective was to assess the risks for DHPs providing dental care during the pandemic based on available scientific evidence. Methods We reviewed the best available evidence and estimated the annualized risk (p= d a s (1−1- p 0 p 1 (1- e ) y n ) for a DHP during the COVID-19 pandemic based on the following basic parameters: p 0 , the prevalence of asymptomatic patients in the local population; p 1 , the probability that a DHP gets infected by an asymptomatic patient; e , the effectiveness of the PPE; s , the probability of becoming symptomatic after getting infected from asymptomatic patient; d a , the probability of dying from the disease in age group a ; n, number of patients seen per day; and y, number of days worked per year. Results With the assumption that DHPs work fulltime and wear a N95 mask, the annualized probability for a DHP to acquire COVID-19 infection in a dental office, become symptomatic, and die from the infection is estimated at 1:13,000 (0.008 %) in a medium sized city in the US at the peak of the pandemic. The risk estimate is highly age-dependent. Risk to DHPs under the age of 70 is negligible when prevalence of asymptomatic cases is low in the local community. Conclusions Risk of COVID-19 transmission in dental office is very low based on available evidence on effectiveness of PPE and prevalence of asymptomatic patients. Face shields and pre-procedure oral rinses may further reduce the risks. Clinical significance DHPs should follow guidelines on pre-appointment protocols and on PPE use during dental treatments to keep the risk low.

“…Accordingly, the prevalence of infection among the medical staff members in centers receiving COVID-19 patients has been reported as much higher than that of centers not receiving COVID-19 patients. 29 In the same way, physicians, nurses and health technicians with direct contact with COVID-19 patients have been more likely to be infected than those without, like clerical workers. 16 However, several studies have not identified a statistically significant difference in the proportion of infected HCWs from hospital units firstly involved in close contact with COVID-19 patients compared with intermediate- or low-risk units.…”

Background During the COVID-19 pandemic, the health care workers (HCWs) at the frontline have been largely exposed to infected patients, running a high risk of being infected by the SARS-CoV-2 virus. Since limiting transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in health care setting is crucial to avoid the community spread of SARS-CoV-2, we want to share our experience as an early hit hospital where standard infection control practices have been conscientiously applied and effective. We believe that our example, as first and hardest hit country, might be a warning and aid not only for those who have been hit later, but also for a second fearful wave of contagion. In addition, we want to offer an insight on modifiable risk factors for HWs-related infection. Methods Demographic, lifestyle, work-related and comorbidities data of 1447 HCWs, which underwent a nasopharyngeal swab for SARS-CoV-2, were retrospectively collected. For the 164 HCWs positive for SARS-CoV-2, data about safety in the workplace, symptoms and clinical course of COVID-19 were also collected. Cumulative incidence of SARS-CoV-2 infection was estimated. Risk factors for SARS-CoV-2 infection were assessed using a multivariable Poisson regression. Results The cumulative incidence of SARS-CoV-2 infection among the screened HCWs was 11.33% (9.72–13.21). Working in a COVID-19 ward, being a former smoker (versus being a person who never smoked) and BMI was positively associated with SARS-CoV-2 infection, whereas being a current smoker was negatively associated with this variable. Conclusions Assuming an equal accessibility and proper use of personal protective equipment of all the HCWs of our Hospital, the great and more prolonged contact with COVID-19 patients remains the crucial risk factor for SARS-CoV-2. Therefore, increased and particular care needs to be focused specifically on the most exposed HCWs groups, which should be safeguarded. Furthermore, in order to limit the risk of asymptomatic spread of SARS-CoV-2 infection, the HCWs mild symptoms of COVID-19 should be considered when evaluating the potential benefits of universal staff testing.

“…In a similar manner, in the view of a large amount of SARS-CoV-2 hospitalized infected patients in the infectious and respiratory diseases units, working in the aforementioned facilities has been assumed to be risky too. Accordingly, the prevalence of infection among the medical staff members in centres receiving COVID-19 patients has been reported as much higher than that of centres not receiving COVID-19 patients [31]. In the same way, physicians, nurses, and health technicians with direct contact with COVID-19 patients have been more likely to be infected than those without, like clerical workers [18].…”

Purpose: During the COVID-19 pandemic, the health care workers (HCWs) at the frontline have been largely exposed to infected patients, running an high risk of being infected by the SARS-CoV-2 virus. This study investigates the epidemiological, clinical and lifestyles characteristics that might play roles in the susceptibility of HCWs to COVID-19 in a hit Italian hospital. Methods:Demographic, lifestyle, work-related and comorbidities data of 1447 HCWs which underwent a nasopharyngeal swab for SARS-CoV-2 were retrospectively collected. For the 164 HCWs positive for SARS-CoV-2, data about safety in the workplace, symptoms and clinical course of COVID-19 were also collected. Cumulative incidence of SARS-CoV-2 infection was estimated. Risk factors for SARS-CoV-2 infection were assessed using a multivariable Poisson regression. Results: The cumulative incidence of SARS-CoV-2 infection among the screened HCWs was 11.33 (9.72-13.21). Working in a COVID-19 ward, being a former smoker (vs being a person who never smoked) and BMI were positively associated with SARS-CoV-2 infection, whereas being a current smoker was negatively associated with this variable.
