One of the side-effects of the COVID-19 pandemic is a global change in work ergonomic patterns as millions of people replaced their usual work environment with home to limit the spread of the severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) infection. The aim of our cross-sectional pilot study was to identify musculoskeletal pain that may have resulted from this change and included 232 telecommunications company workers of both genders [121 (52.2 %) men aged 23–62 (median 41; interquartile range 33–46 yrs.) and 111 (47.8 %) women aged 23–53 (median 40; interquartile range 33–44)] who had been working from home for eight months (from 16 March to 4 December 2020) before they joined the study. The participants were asked to fill in our web-based questionnaire by self-assessing their experience of hand, lower back, and upper back/neck pain while working at home and by describing their work setting and physical activity. Compared to previous work at the office, 90 (39.1 %) participants reported stronger pain in the lower back, 105 (45.7 %) in the upper back/neck, and 63 (27.2 %) in their hands. Only one third did not report any musculoskeletal problems related to work from home. Significantly fewer men than women reported hand, lower back, and upper back/ neck pain (p=0.033, p=0.001 and p=0.013, respectively). Sixty-nine workers (29.9 %) reported to work in a separate room, 75 (32.4 %) worked in a separate section of a room with other household members, whereas 87 (37.7 %) had no separate work space, 30 of whom most often worked in the dining room. Ninety-five participants (40.9 %) had no office desk to work at, and only 75 (32.3 %) used an ergonomic chair. Of those who shared their household with others (N=164), 116 (70.7 %) complained about constant or occasional disturbances. Over a half of all participants (52 %) said that they worked longer hours from home than at work, predominantly women (p=0.05). Only 69 participants (29.9 %) were taking frequent breaks, predominantly older ones (p=0.006). Our findings clearly point to a need to inform home workers how to make more ergonomic use of non-ergonomic equipment, use breaks, and exercise and to inform employers how to better organise working hours to meet the needs of work from home.

Healthcare workers (HCWs) are considered to run a higher occupational risk of becoming infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and develop coronavirus disease (COVID-19) than the rest of the population. The aim of this study was to describe and analyse the characteristics of work-related COVID-19 in Croatian HCWs. Study participants were HCWs who contacted their occupational physician between 1 May 2020 and 12 November 2020 with a request for the registration of COVID-19 as an occupational disease. All participants filled out our online Occupational COVID-19 in Healthcare Workers Questionnaire. The study included 59 HCWs (median age 45.0, interquartile range 36.0–56.0 years). Most (78 %) were nurses or laboratory technicians, and almost all (94.9 %) worked in hospitals. Hierarchical cluster analysis revealed three clusters of COVID-19-related symptoms: 1) elevated body temperature with general weakness and fatigue, 2) diarrhoea, and 3) headache, muscle and joint pain, anosmia, ageusia, and respiratory symptoms (nasal symptoms, burning throat, cough, dyspnoea, tachypnoea). Almost half (44.6 %) reported comorbidities. Only those with chronic pulmonary conditions were more often hospitalised than those without respiratory disorders (57.1 % vs. 2.5 %, respectively; P=0.001). Our findings suggest that work-related COVID-19 among Croatian HCWs is most common in hospital nurses/laboratory technicians and takes a mild form, with symptoms clustering around three clinical phenotypes: general symptoms of acute infection, specific symptoms including neurological (anosmia, ageusia) and respiratory symptoms, and diarrhoea as a separate symptom. They also support evidence from other studies that persons with chronic pulmonary conditions are at higher risk for developing severe forms of COVID-19.

Coronavirus disease 2019 (COVID-19) can be diagnosed as occupational disease by an occupational health physician (OHP), if supported by relevant work-related and medical documentation. The aim of this study was to analyse such documentation submitted by Croatian healthcare workers (HCWs) and discuss its relevance in view of European and Croatian guidelines. The study included 100 Croatian HCWs who were SARS-CoV-2-positive and requested that their infection be diagnosed as occupational disease by their OHPs from 1 May 2020 to 10 March 2021. As participants they were asked to fill out our online Occupational COVID-19 in Healthcare Workers Questionnaire. For the purpose of this study we analysed answers about the type of close contact at the workplace, COVID-19 symptoms, and enclosed work-related (job description, employer statement about exposure to SARS-CoV-2) and medical documentation (positive SARS-CoV-2 polymerase chain reaction test and patient history confirming the diagnosis of COVID-19). Most participants were working in hospitals (N=95), mostly nurses (N=75), who became infected by a patient (N=68) or colleague (N=31), and had at least one COVID-19 symptom (N=87). Eighty participants did not enclose obligatory documents, 41 of whom failed to submit job description and 31 both job description and employer statement. These findings confirm that the major risk of occupational COVID-19 in HCWs is close contact with patients and colleagues, and points out the need for better cooperation between OHPs, occupational safety experts, employers, and diseased workers.
