“…One case series also reported SARS-CoV-2 infection in cleaning staff who had no contact with patients with COVID-19 (24). Of the eight infected cleaners in the study, only one wore a face shield and had limited opportunities for infection prevention and control (IPC) training (24). In another observational study, cleaning staff had the highest seropositivity among staff working in hospitals with COVID-19 outbreaks (23).…”

As coronavirus disease 2019 outbreaks in healthcare facilities are a serious public health concern, we performed a case-control study to investigate the risk of COVID-19 infection in healthcare workers. We collected data on participants' sociodemographic characteristics, contact behaviors, installation status of personal protective equipment, and polymerase chain reaction testing results. We also collected whole blood and assessed seropositivity using the electrochemiluminescence immunoassay and microneutralization assay. In total, 161 (8.5%) of 1,899 participants were seropositive between August 3 and November 13, 2020. Physical contact (adjusted odds ratio 2.4, 95% confidence interval 1.1-5.6) and aerosol-generating procedures (1.9, 1.1-3.2) were associated with seropositivity. Using goggles (0.2, 0.1-0.5) and N95 masks (0.3, 0.1-0.8) had a preventive effect. Seroprevalence was higher in the outbreak ward (18.6%) than in the COVID-19 dedicated ward (1.4%). Results showed certain specific risk behaviors of COVID-19; proper infection prevention practices reduced these risks.

Background: The coronavirus disease 2019 (COVID-19) pandemic created new challenges for private eye care practices. Safety issues were encountered by both the healthcare workers and patients. This short communication addresses the changes made in our private eye care practice during the pandemic and the valuable lessons learned for the future. Methods: We describe the challenges faced in our tertiary private eye care practice in India with respect to treating patients and preventing the transmission of COVID-19, considering the economic hardship within this area. We discuss the emerging economic, medical, legal, educational, and psychological issues and their solutions, which eye care hospitals could follow in the future to ensure safety without compromising quality of care. Results: Hospitals required efficient operation with reduced fixed expenses. Clinical practices were followed in the hospital as per the recommendations of the country’s apex ophthalmic body. Proper triage and prescreening of patients at the entrance, digitalization, teleophthalmology, staggered appointments, and role-appropriate personal protective equipment were important preventive measures. The operating room protocols were modified to ensure the safety of the operating staff. Special consent was obtained from patients to safeguard against legal repercussions arising from the pandemic. The training of residents and fellows led to new avenues, including the use of digital tools. Hospitals attempted to provide counseling and psychological support to their doctors and staff during these trying times. Conclusions: The COVID-19 pandemic will not be the last pandemic to occur in an ever-changing world. This event provided us with many new insights into the economic, clinical, legal, and psychological challenges of the COVID-19 pandemic and with ways to overcome these challenges and emerge intact. Clinical and surgical training suffered during the pandemic; however, the impact was only temporary. Clinical research gained respect because of the efforts undertaken during the pandemic. The pandemic was exceptionally harsh on many private eye care practices, and we hope to provide useful and comprehensive solutions on how to successfully navigate a similar situation if encountered in the future.

Potential risk of SARS-CoV-2 infection among people handling linens used by COVID-19 patients before and after washing

The risk of SARS-CoV-2 infection when people handle linens is uncertain. We examined the presence of SARS-CoV-2 on linens, in the air, and on personal protective equipment (PPE) to assess potential infection risk among individuals who handle linens used by SARS-CoV-2-infected people. Patients in a hospital and an accommodation facility who tested positive for SARS-CoV-2 participated in this study in 2020. Linen samples before washing or disinfection, rinse water after washing or disinfection, air in the workplace at the hospital and an accommodation facility, and the PPE worn by linen-handling people were tested for SARS-CoV-2 RNA and viable viruses. Among 700 samples from 13 SARS-CoV-2-infected participants and their surrounding environment, SARS-CoV-2 RNA was detected from 14% (52/362) of the linens used by COVID-19 patients (cycle threshold [Ct] value: 33–40). SARS-CoV-2 RNA was detected from 8% (2/26) of rinse water after washing or disinfection, from 15% (16/104) of air samples in the workspace, and from 10% (5/52) of gowns worn by linen-handling people, all with high Ct values (> 36). No SARS-CoV-2 was isolated from any samples. The potential risk of SARS-CoV-2 infection from handling linens used by SARS-CoV-2-infected people exists but appears to below.
