Responding to COVID-19 in Hong Kong

Lessons learned 1 year after SARS-CoV-2 emergence leading to COVID-19 pandemic

Without modern medical management and vaccines, the severity of the Coronavirus Disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome (SARS) coronavirus 2 (SARS-CoV-2) might approach the magnitude of 1894-plague (12 million deaths) and 1918-A(H1N1) influenza (50 million deaths) pandemics. The COVID-19 pandemic was heralded by the 2003 SARS epidemic which led to the discovery of human and civet SARS-CoV-1, bat SARS-related-CoVs, Middle East respiratory syndrome (MERS)-related bat CoV HKU4 and HKU5, and other novel animal coronaviruses. The suspected animal-to-human jumping of 4 betacoronaviruses including the human coronaviruses OC43(1890), SARS-CoV-1(2003), MERS-CoV(2012), and SARS-CoV-2(2019) indicates their significant pandemic potential. The presence of a large reservoir of coronaviruses in bats and other wild mammals, culture of mixing and selling them in urban markets with suboptimal hygiene, habit of eating exotic mammals in highly populated areas, and the rapid and frequent air travels from these areas are perfect ingredients for brewing rapidly exploding epidemics. The possibility of emergence of a hypothetical SARS-CoV-3 or other novel viruses from animals or laboratories, and therefore needs for global preparedness should not be ignored. We reviewed representative publications on the epidemiology, virology, clinical manifestations, pathology, laboratory diagnostics, treatment, vaccination, and infection control of COVID-19 as of 20 January 2021, which is 1 year after person-to-person transmission of SARS-CoV-2 was announced. The difficulties of mass testing, labour-intensive contact tracing, importance of compliance to universal masking, low efficacy of antiviral treatment for severe disease, possibilities of vaccine or antiviral-resistant virus variants and SARS-CoV-2 becoming another common cold coronavirus are discussed.

The Role of Infection Control Measures in Ophthalmology: Do They Prevent COVID-19 Infection Among Ophthalmologists in Egypt? A Survey-Based Study

Introduction

Ophthalmologists are at a high risk of coronavirus disease 2019 (COVID-19) infection owing to their working environments and proximity to patients during examinations. Compliance with infection control measures in examination offices can lessen the risk of infection to this group. In Egypt, several deaths from COVID-19 have been reported among ophthalmologists; therefore, we studied the prevalence of COVID-19 infections in this group and assessed ophthalmologists' commitments to recommended infection control measures.

Aim

To evaluate the rate of COVID-19 infections among ophthalmologists, identify risk factors for infections, and evaluate ophthalmologists' commitments to infection control measures in their medical facilities.

Methods

An online questionnaire was designed and distributed to ophthalmologists in the Cairo Governorate from May 1, 2021 to mid-June 2021.

Results

Out of 161 responders, the percentage of COVID-19 infections was 52.8% (85 responders). This was significantly higher among younger ophthalmologists (P-value = 0.019) and those with fewer years of experience (P-value = 0.010). Adopting full precautions while examining patients with or without respiratory illness were significantly associated with a lower infection rate (P-value = 0.019 and 0.046, respectively). A significantly higher infection rate was reported for ophthalmologists who examined known COVID-19 patients at outpatient clinics, even when taking precautions (P-value = 0.032). A lower rate of COVID-19 infection was significantly associated with adopting full precautions while operating on suspected or nonsuspected COVID-19 patients (P-value = 0.007 and 0.003, respectively).

Conclusion

Both young age and limited experience were significant infection risk factors in our study. The most important infection control measures that significantly decreased infection risks were adherence to full protective measures while working in outpatient clinics and operating rooms.

Multilevel Factors Affecting Healthcare Workers' Perceived Stress and Risk of Infection During COVID-19 Pandemic

Objectives: This study aimed to identify key factors affecting Healthcare workers (HCWs) perceived stress and risk of contracting COVID-19 among themselves and their family members during the pandemic. Methods: A cross-sectional online questionnaire study was conducted between 19 March and April 5, 2020 in Hong Kong. HCWs from public hospitals and private dentists, and their family members participated. Results: A total of 747 HCWs and 245 family members participated. Higher perceived stress in HCWs was associated with more negative changes in family relationship (p = 0.025). The HCWs' perceived stress, however, was positively associated with family cohesion (p = 0.033) and stress levels of family members (p < 0.001). The level of HCWs' satisfaction toward the hospital policies in response to the COVID-19 outbreak was associated with lower levels of perceived stress and risk of themselves or their family members contracting COVID-19. HCWs' previous frontline experience of SARS was significantly associated with less perceived risk of themselves or their family members contracting COVID-19. Conclusion: Hospital policies addressing HCWs' needs, frontline experience of SARS, and family relationship influenced psychological wellbeing of HCWs during the COVID-19 outbreak.
