AbstractObjective:To characterize the magnitude of virus contamination on personal protective equipment (PPE), skin, and clothing of healthcare workers (HCWs) who cared for patients having acute viral infections.Design:Prospective observational study.Setting:Acute-care academic hospital.Participants:A total of 59 HCWs agreed to have their PPE, clothing, and/or skin swabbed for virus measurement.Methods:The PPE worn by HCW participants, including glove, face mask, gown, and personal stethoscope, were swabbed with Copan swabs. After PPE doffing, bodies and clothing of HCWs were sampled with Copan swabs: hand, face, and scrubs. Preamplification and quantitative polymerase chain reaction (qPCR) methods were used to quantify viral RNA copies in the swab samples.Results:Overall, 31% of glove samples, 21% of gown samples, and 12% of face mask samples were positive for virus. Among the body and clothing sites, 21% of bare hand samples, 11% of scrub samples, and 7% of face samples were positive for virus. Virus concentrations on PPE were not statistically significantly different than concentrations on skin and clothing under PPE. Virus concentrations on the personal stethoscopes and on the gowns were positively correlated with the number of torso contacts (P < .05). Virus concentrations on face masks were positively correlated with the number of face mask contacts and patient contacts (P < .05).Conclusions:Healthcare workers are routinely contaminated with respiratory viruses after patient care, indicating the need to ensure that HCWs complete hand hygiene and use other PPE to prevent dissemination of virus to other areas of the hospital. Modifying self-contact behaviors may decrease the presence of virus on HCWs.

Background The Covid-19 pandemic has caused changes in the surgical treatment of non-Covid patients, especially in thoracic surgery because most procedures are aerosol generating. Hospital Kuala Lumpur, where thoracic procedures are performed, was badly affected. We describe our experience in performing aerosol generating procedures safely in thoracic surgery during the Covid-19 era. Methods Medical records of patients who underwent thoracic surgery from March 18, 2020 to May 17, 2020 were reviewed retrospectively. All patients undergoing thoracic surgery were tested for Covid-19 using the reverse transcriptase polymerase chain reaction method. Patients with malignancy were observed for 10 to 14 days in the ward after testing negative. The healthcare workers donned personal protective equipment for all the cases, and the number of healthcare workers in the operating room was limited to the minimum required. Results A total of 44 procedures were performed in 26 thoracic surgeries. All of these procedures were classified as aerosol generating, and the mean duration of the surgery was 130 ± 43 minutes. None of the healthcare workers involved in the surgery were exposed or infected by Covid-19. Conclusion Covid-19 will be a threat for a long time and thoracic surgeons must continue to provide their services, despite having to deal with aerosol generating procedures, in the new normal. Covid-19 testing of all surgical candidates, using the reverse transcriptase polymerase chain reaction, donning full personal protective equipment for healthcare workers, and carefully planned procedures are among the measures suggested to prevent unnecessary Covid-19 exposure in thoracic surgery.

BACKGROUND፡ Coronavirus disease 2019 is an infectious disease caused by severe acute respiratory syndrome coronavirus 2. This study aimed to address the preventive procedures to protect healthcare workers at hospital to avoid COVID-19, and infection control procedures to protect dental professionals in dental office.METHODS: We conducted a search of published articles from PubMed, google scholar databases using key words such as COVID-19, healthcare worker, infection control, and dental practice. Relevant articles were identified and reviewed. Most published papers were clinical reports and case studies. We have selected some of the current published papers written in English in 2020.RESULTS: Infection control procedures to protect health workers at hospitals, and dental professionals at dental office were summurised and presented. Infection control procedures for healthcare workers at hospitals include Personal protective equipment, Korea filter (KF)94 respirator, goggles, face protector,disposable waterproof long-arm gown, and gloves, and others. Extra-protection procedures should be taken with old and vulnerable healthcare workers. Dental professionals should evaluate patients in advance before starting dental treatment. Aerosols generating procedures should be avoided and personal protective equipment should be used. Dental treatment should be restricted to emergency cases only.CONCLUSION: Old medical staff should be in safer distance to avoid infection, but young physicians and nurses should work at frontline as their immunity is better than their colleagues at old age. Screening patients and measurement of the body temperature are essential measures before dental treatment.

The world is now facing a new unexpected pandemic caused by SARS-CoV-2, which is a coronavirus that mainly targets the lungs, a very vital and sensitive organ of the body. Research and healthcare workers are still struggling to contain the disease and eradicate the virus. Before the invention of a vaccine, the virus may take at least several more millions of lives. On top of this, dermatologists are facing numerous challenges because of the regulations put forward by the WHO and local governments. This article discusses in detail various dermatological eruptions caused by the personal protective equipment (PPE) used in combating the disease. This should be an eye-opener for dermatologists worldwide.

The Impact

The pandemic has been afflicting the planet for over a year and from the occupational point of view, healthcare workers have recorded a substantial increase in working hours. The use of personal protective equipment (PPE), necessary to keep safe from COVID-19 increases the chances of overheating, especially during the summer seasons which, due to climate change, are becoming increasingly warm and prolonged. A web survey was carried out in Italy within the WORKLIMATE project during the summer and early autumn 2020. Analysis of variance (ANOVA) was used to evaluate differences between groups. 191 questionnaires were collected (hospital doctor 38.2%, nurses 33.5%, other healthcare professionals 28.3%). The impact of PPE on the thermal stress perception declared by the interviewees was very high on the body areas directly covered by these devices (78% of workers). Workers who used masks for more than 4 h per day perceived PPE as more uncomfortable (p < 0.001) compared to the others and reported a greater productivity loss (p < 0.001). Furthermore, the study highlighted a high perception of thermal stress among healthcare workers that worn COVID-19-PPE and this enhances the need for appropriate heat health warning systems and response measures addressed to the occupational sector.

The worldwide outbreak of the COVID-19 drastically increased pressure on medical resources and highlighted the need for rapidly available, large-scale and low-cost personal protective equipment (PPE). In this work, an alternative full-face mask is adapted from a modified snorkel mask to be used as PPE with two medical grade filters and a 3D-printed adapter. As the mask covers the eyes, mouth and nose, it acts as a full-face shield, providing additional protection to healthcare workers. The filtration efficiency of different medical filters is measured for particles below 300 nm to cover the size of the SARS-CoV-2 and small virus-laden droplets. The filtration performance of the adapted full-face mask is characterized using NaCl particles below 500 nm and different fitting scenarios. The mask is compared to a commercial respirator and characterized according to the EN 149 standard, demonstrating that the protection fulfills the requirements for the FFP2 level (filtering face-piece 2, stopping at least 94% of airborne particles). The device shows a good resistance to several cycles of decontamination (autoclaving and ethanol immersion), is easy to be produced locally at low cost and helps addressing the shortage in FFP2 masks and face shields by providing adequate protection to healthcare workers against particles below 500 nm.

BACKGROUND COVID-19 is a health emergency. It was found in Wuhan, Hubei Province, China and has rapidly spread around the world, leaving no country untouched. SARS-CoV-2 is a respiratory infection characterised by a pneumonia of unknown aetiology. It is transmitted through respiratory droplets, for example: when breathing, talking and coughing. Transmission of the virus is high. Healthcare workers play critical roles in providing help to those affected with COVID-19; this could not be done without the use of personal protective equipment. Personal protective equipment, also known as PPE, involves the use of goggles, masks, gloves and gowns with the aims of protecting healthcare workers and reducing the transmission of the virus. PPE has proven to be effective in reducing the transmission of the virus, however multiple reports of skin disease and damage associated with occupational mask wear have come to light. OBJECTIVE The objective is to review current literature of newly arising dermatological conditions as a result of occupational mask wear during the COVID-19 pandemic. METHODS A qualitative review investigating new reports of dermatological conditions associated with occupational mask wear was carried out by referencing keywords, including: “covid mask dermatology, covid mask skin and covid mask skin damage” from the databases of PubMed, Google Scholar and ResearchGate. 287 articles were found (PubMed: 59, Google Scholar: 90, ResearchGate: 138); 40 articles successfully formed part of the study. A further 7 articles were found by manually reviewing reference lists of the included articles. The findings were tabulated and analysed under the headings: dermatological diagnosis, causes and management. RESULTS Qualitative analysis of the reviewed data was carried out. A number of dermatological conditions, as listed in Table 1, were found to be increasing due to prolonged and frequent contact of facial masks. The number of healthcare workers affected by symptoms of skin damage was significant in almost all studies, showing a worldwide problem was present. Pressure-related injuries were often the most serious complaint; recommendations to reduce this type of injury include hydrocolloid dressings, plastic handles, education and regular moisturising. Innovation of protective equipment as well as services, such as virtual clinics, need to be advanced to protect the welfare of staff. CONCLUSIONS In these unprecedented times, PPE has been an effective barrier in reducing the transmission of COVID-19 to healthcare workers. This has allowed healthcare workers to bravely provide care to patients. However, the evidence collated suggests that despite the obvious benefits of using facial masks to protect the respiratory system, there are also considerable health consequences to the skin. Future research needs to pursue the advancement of facial masks which considers both the protection of the respiratory system as well as skin care, something which this review demonstrates has been neglected.

Second Wave

Frontline healthcare workers (HCWs) involved in the COVID-19 response have a higher risk of experiencing psychosocial distress amidst the pandemic. Between July and September 2020, a second wave of the COVID-19 pandemic appeared in Vietnam with Da Nang city being the epicenter. During the outbreak, HCWs were quarantined within the health facilities in a bid to limit the spread of COVID-19 to their respective communities. Using the stress component of the 21-item Depression, Anxiety and Stress Scale (DASS-21), we assessed the level of stress among HCWs in Da Nang city. Between 30 August and 15 September 2020, 746 frontline HCWs were recruited to fill in an online structured questionnaire. Overall, 44.6% of participants experienced increased stress and 18.9% severe or extremely severe stress. In multivariable analysis, increased stress was associated with longer working hours (OR = 1.012; 95% CI: 1.004–1.019), working in health facilities providing COVID-19 treatment (OR = 1.58, 95% CI: 1.04–2.39), having direct contact with patients or their bio-samples (physicians, nurses and laboratory workers; OR = 1.42, 95% CI: 1.02–1.99), low confidence in the available personal protective equipment (OR = 0.846; 95% CI: 0.744–0.962) and low knowledge on COVID-19 prevention and treatment (OR = 0.853; 95% CI: 0.739–0.986). In conclusion, many frontline HCWs experienced increased stress during the COVID-19 outbreak in Da Nang city. Reducing working time, providing essential personal protective equipment and enhancing the knowledge on COVID-19 will help to reduce this stress. Moreover, extra support is needed for HCWs who are directly exposed to COVID-19 patients.

ABSTRACT Objective: Bottlenecks in the personal protective equipment (PPE) supply chain have contributed to shortages of PPE during the COVID-19 pandemic, resulting in fractures in the functionality of healthcare systems. This study was conducted with the aim of determining the effectiveness of retrofitted commercial snorkel masks as an alternative respirator for healthcare workers during infectious disease outbreaks. Methods: A retrospective analysis was performed, analyzing qualitative and quantitative fit test results of the retrofitted Aria Ocean Reef® full-face snorkeling mask on healthcare workers at the McGill University Health Centre between April-June 2020. Historical fit test results, using medical-grade respirators, for healthcare workers were also analyzed. Results: During the study period, 71 participants volunteered for fit testing, 60.6% of which were nurses. The overall fit test passing rate using the snorkel mask was 83.1%. Of the participants who did not previously pass fit testing with medical-grade respirators, 80% achieved a passing fit test with the snorkel respirator. Conclusions: The results suggest that this novel respirator may be an effective and feasible alternative solution to address PPE shortages, while still providing healthcare workers with ample protection. Additional robust testing will be required to ensure that respirator fit is maintained, after numerous rounds of disinfection.
