SARS-CoV-2 infection among employees working from home and on site: An occupational study in Switzerland

During the COVID-19 pandemic, many companies implemented working from home to mitigate the spread of the disease among their employees. Using data from Corona Immunitas Nestlé, a seroepidemiological study conducted among employees from two Nestlé sites in Switzerland, we aimed to investigate whether there was a difference in SARS-CoV-2 infection rates between employees working most of the time from home and employees mobilized in a workplace equipped with a specialized occupational safety unit and strict sanitary measures. We also investigated whether this association was modified by household size, living with children, vulnerability, worries about an infection, and worries about adverse health consequences if infected. Data were collected between 8 December 2020, and 11 February 2021. Previous SARS-CoV-2 infections were ascertained by the presence of anti-SARS-CoV-2 IgG antibodies in the blood. Of the 425 employees included (53% women;mean age 42 years ranging between 21 and 64 years), 37% worked most of the time from home in 2020 and 16% had been infected with SARS-CoV-2. Participants who worked most of the time from home in 2020 had slightly higher odds of being infected with SARS-CoV-2 compared to participants who never or only sometimes worked from home (adjusted OR 1.29, 95% CI 0.73–2.27). The association was stronger in participants living alone or with one other person (adjusted OR 2.62, 95% CI 1.13–6.25). Among participants living with two or more other persons (adjusted OR 0.66, 95% CI 0.30–1.39) and among vulnerable participants (adjusted OR 0.53, 95% CI 0.13–1.93), working from home tended to be associated with lower odds of infection. In conclusion, in a context of strict sanitary measures implemented in the workplace, employees working from home did not seem to be at lower risk of infection compared to those working on site, especially if living alone or with one other person.

Practicing traditional Chinese medicine in the COVID-19 pandemic in Switzerland - an exploratory study.

BACKGROUND: To curb the spread of the first wave of the COVID-19 pandemic, the Swiss government declared a state of health emergency and ordered a legal restriction concerning the opening of healthcare institutions. In this study, we aimed to assess the proportion of traditional Chinese medicine (TCM) physicians and therapists who consulted patients regarding COVID-19 during the first wave of the pandemic in 2020 in Switzerland, as well as the extent to which COVID-19 affected their practices during the same period. METHODS: A retrospective study was performed by using a questionnaire from January to April 2021 among a random sample of TCM physicians and therapists based in Switzerland. The survey included questions on demographic characteristics, opening status of practices, channels of communication used for the medical encounter, and experience in managing the prevention, acute, and recovery stages of COVID-19 infection. RESULTS: Among the 320 participants, 76% consulted a patient regarding COVID-19 at least once. Overall, physicians and therapists consulted more patients during recovery (76.3%) and prevention (67.8%) than during the acute stage (19.8%) of the disease. Acupuncture was the most frequently used technique among TCM therapists and physicians consulting for prevention (80.4%) and recovery (92.5%), whereas Chinese pharmacopeia was the most used technique among those consulting for the acute stage (59.3%). Of those who closed their practices from March to April 2020 but kept consulting, telephone (30.4%) and home visits (29.9%) were the two principal methods of consultation. CONCLUSIONS: The restriction concerning the opening of practices induced a loss of the health workforce, especially among TCM therapists. Nonetheless, TCM therapists and physicians consulted patients regarding COVID-19, especially during the recovery stage. As there is a demand for the use of TCM in the context of COVID-19, it raises the need for a better consideration of TCM in the Swiss health care system.

Is living in a household with children associated with SARS-CoV-2 seropositivity in adults? Results from the Swiss national seroprevalence study Corona Immunitas.

BACKGROUND: We aimed to determine whether living in a household with children is associated with SARS-CoV-2 seropositivity in adults and investigated interacting factors that may influence this association. METHODS: SARS-CoV-2 serology testing was performed in randomly selected individuals from the general population between end of October 2020 and February 2021 in 11 cantons in Switzerland. Data on sociodemographic and household characteristics, employment status, and health-related history was collected using questionnaires. Multivariable logistic regression was used to examine the association of living with children <18 years of age (number, age group) and SARS-CoV-2 seropositivity. Further, we assessed the influence of reported non-household contacts, employment status, and gender. RESULTS: Of 2393 working age participants (18-64 years), 413 (17.2%) were seropositive. Our results suggest that living with children and SARS-CoV-2 seropositivity are likely to be associated (unadjusted odds ratio (OR) 1.22, 95% confidence interval [0.98-1.52], adjusted OR 1.25 [0.99-1.58]). A pattern of a positive association was also found for subgroups of children aged 0-11 years (OR 1.21 [0.90-1.60]) and 12-17 years (OR 1.14 [0.78-1.64]). Odds of seropositivity were higher with more children (OR 1.14 per additional child [1.02-1.27]). Men had higher risk of SARS-CoV-2 infection when living with children than women (interaction: OR 1.74 [1.10-2.76]). CONCLUSIONS: In adults from the general population living with children seems associated with SARS-CoV-2 seropositivity. However, child-related infection risk is not the same for every subgroup and depends on factors like gender. Further factors determining child-related infection risk need to be identified and causal links investigated. TRIAL REGISTRATION: https://www.isrctn.com/ISRCTN18181860 .

Interest and need for continuing medical education in pediatric complementary and integrative medicine: a cross-sectional survey from Switzerland.

BACKGROUND: Pediatric integrative medicine, combining conventional and complementary medical approaches for children and adolescents, is an integral part of the health care system in Switzerland. However, there is still a lack of complementary and integrative medicine topics in training and continuing educational programs. For the first time on a national level, the 2021 annual conference of the Swiss Society of Pediatrics was entirely dedicated to the topic of integrative medicine. METHODS: Using a cross-sectional online survey, this study investigated congress participants' evaluation and feedback with the aim to assess whether the program had met their objectives and to get empirical data on their attitude, expectations and needs regarding pediatric complementary and integrative medicine. Descriptive methods were used to present the results. RESULTS: Among 632 participants of the conference, 228 completed the evaluation form (response rate 36%). The overall feedback about the congress and the main theme of pediatric integrative medicine was clearly positive. The majority of respondents had achieved their educational objectives including complementary and integrative medicine issues. 82% were motivated to learn more about complementary and integrative medicine and 66% were stimulated to integrate complementary therapies into their professional practice. CONCLUSION: This study from Switzerland confirms the interest in integrative medicine among pediatricians and supports the need for pre- and postgraduate pediatric training on topics related to complementary and integrative medicine. Developing and adapting training and continuing medical education based on evaluations of participant feedback can promote professional development and improve patient care for the benefit of physicians and patients.
