ObjectivesTo assess the seroprevalence of SARS-CoV-2 antibodies in municipal employees of Northern Portugal during the first pandemic wave (May–June 2020) and its association with potentially related risk factors for infection.Material and MethodsThe authors assessed municipal employees of 2 cities in Northern Portugal, in whom serological tests to SARS-CoV-2 and an epidemiological survey were applied. The authors assessed the proportion of individuals presenting IgM and/or IgG antibodies to SARS-CoV-2, and evaluated the association between having positive serological test results, epidemiologic variables and clinical presentations. Reported symptoms were evaluated on their sensitivity, specificity, and predictive values.ResultsThe authors assessed 1696 employees, of whom 22.0% were firefighters, 10.4% were police officers, 10.3% were maintenance workers, and 8.1% were administrative assistants. The seroprevalence of SARS-CoV-2 infection was 2.9% (95% CI: 2.1–3.7%). Administrative assistants comprised the professional group with highest seroprevalence of SARS-CoV-2 (OR = 1.9 in the comparison with other occupational groups, 95% CI: 0.8–4.3, p = 0.126). The seroprevalence of SARS-CoV-2 infection among those who were in direct contact with COVID-19 patients in their professional activity was 3.9%, compared to 2.7% among those who were not in direct contact with such patients (OR = 1.5, 95% CI: 0.8–2.8, p = 0.222). The highest risk of infection was associated with the presence of a confirmed SARS-CoV-2 infection in the household (OR = 17.4, 95% CI: 8.3–36.8, p < 0.001). Living with a healthcare professional was not associated with a higher risk of infection (OR = 1.0, 95% CI: 0.4–2.5, p = 0.934). Anosmia/dysgeusia was the symptom with the highest positive predictive value (52.2%, 95% CI: 31.8–72.6, p < 0.001) and specificity (99.3%, 95% CI: 98.9–99.7, p < 0.001), while cough was the most prevalent symptom among SARS-CoV-2 seropositive participants (36%).ConclusionsThe authors observed a SARS-CoV-2 seroprevalence of 2.9% among assessed municipal employees. Anosmia/dysgeusia was the COVID-19 symptom which displayed the highest positive predictive value and specificity.

Opis:
ObjectivesThe COVID-19 pandemic is due to SARS-CoV-2 coronavirus infections. It swept across the world in the spring of 2020, and so far it has caused a huge number of hospitalizations and deaths. In the present study, the authors investigated serum anti-SARS-CoV-2 antibody prevalence in the period of June 1–September 25, 2020, in 7561 subjects in Modena, Northern Italy.Material and MethodsThe study population included 5454 workers referred to testing by their companies, and 2107 residents in the Modena area who accessed testing through self-referral.ResultsThe authors found the overall seroprevalence to be 4.7% (95% confidence interval [CI] 4.2–5.2%), which was higher in women (5.4%, 95% CI: 4.5–6.2%) than in men (4.3%, 95% CI: 3.7–4.9%), and in the oldest age groups (7.3%, 95% CI: 5.2–9.3% for persons aged 60–69 years, and 11.8%, 95% CI: 8.6–15.1%, for persons aged ≥70 years). Among the occupational categories, the highest seroprevalence was found in healthcare workers (8.8%, 95% CI: 7.0–10.5%), dealers and vehicle repairers (5.2%, 95% CI: 2.9–7.6%), and workers in the sports sector (4.0%, 95% CI: 1.8–6.1%), while there was little or no such evidence for those employed in sectors such as transport and storage, accommodation and restaurant services, and the school system. Conclusions: These results have allowed, for the first time, to assess population seroprevalence in this area of Italy severely hit by the epidemic, while at the same time identifying the subgroups at a higher risk of exposure to SARS-CoV-2.

Objectives The objective was to characterize and compare SARS-CoV-2 serology among Norwegian school employees and retail employees, and describe preventive measures taken at the workplaces. Material and Methods A cohort of 238 school and retail employees was enrolled to an ambidirectional cohort study after the first COVID-19 pandemic wave. Self-reported exposure history and serum samples were collected at 10 schools and 15 retail stores in Oslo, Norway, sampled at 2 time-points: baseline (May–July 2020); and follow-up (January–March 2021). SARS-CoV-2 antibodies targeting both spike and nucleocapsid were detected by multiplex microsphere-based serological methods. Results At baseline, 6 enrolled workers (5 in retail) presented with positive SARS-CoV-2 serology, higher than the expected 1% prevalence (3%, 95% CI: 1–6, p = 0.019). At followup, school and retail groups presented 11 new seropositive cases altogether, but groups were not significantly different, although exposure and preventive measures against viral transmission at workplaces were different between groups. Self-reported medical history of COVID-19 infection showed that all but one positive SARS-CoV-2 serological findings arising between baseline and follow-up had been diagnosed with virus testing. Conclusions Distribution of SARS-CoV-2 positive serology after the first wave was slightly higher than expected. Distribution of infection was not significantly different between the groups at baseline nor at follow-up, despite difference in exposure and protective measures. Nearly all new seropositive cases discovered between baseline and follow-up, had already been diagnosed, highlighting the importance of extensive viral testing among workers.

Opis:
Objectives The pandemic caused by the novel coronavirus (SARS-CoV-2) affected a disproportionately high percentage of healthcare workers (HCWs). The aim of the study was to assess the seroprevalence of SARS-CoV-2-specific IgG antibodies in nurses and clinicians working in 2 Slovenian regional hospitals, and to identify the factors associated with seropositivity. Material and Methods The study was designed as a crosssectional study. Clinicians and nurses were invited to participate in November–December 2020. The respondents (813, 65.8%) completed a questionnaire and consented to provide 10 ml of blood for determining the presence of SARS-CoV-2 IgG antibodies. Results The authors observed a seroprevalence rate of 20.4%. The results of the univariate analysis proved that the age of a nurse or clinician was the factor most strongly associated with seropositivity – in fact, the youngest nurses and clinicians were 8.33 times more likely to be seropositive than those in the oldest age group (p = 0.041). Being in contact with a family/household member who was SARS-CoV-2-positive was also a very important factor. In the work-related factors group, being in the contact with a SARS-CoV-2-positive colleague (OR = 2.35, p = 0.026) or being in contact with a COVID-19 patient (OR = 1.96, p = 0.004) correlated with seropositivity. In the primary work location/department group, the only significant association appeared among those working in surgical, ENT or ophthalmology departments. The results of the multivariate analysis further supported the thesis that the age of nurses and clinicians was the factor most strongly associated with seropositivity. The youngest nurses and clinicians were 12.5 times more likely to be seropositive than those in the oldest age group (p = 0.024). Being in contact with a SARS-CoV-2-positive family/household member remained the second most important factor. Conclusions A significant number of clinicians and nurses working in secondary healthcare were infected in the first 9 months of the pandemic.

Opis:
The aim of the study was to assess seroprevalence of anti-SARS-CoV-2 antibodies among healthcare workers (HCW) before introduction of vaccination, in selected areas in Poland as well as to identify potential risk factors and estimate the cumulative incidence of COVID-19 infections in this population.Material and MethodsThe authors conducted a sero-epidemiological, cross-sectional study among HCW of 5 non-COVID-19 hospitals in Poland. The recruitment took place in December 1–23, 2020, all HCW at selected hospitals could volunteer into the study. All persons were screened with rapid SARS-CoV-2 IgM/IgG tests in capillary blood. In case of positive result, 5 ml of venous blood was drawn for confirmatory testing with ELISA assay. The authors estimated prevalence of laboratory confirmed anti-SARS-CoV-2 antibody presence and examined factors associated with positive result. Cumulative incidence was estimated applying 2-source capture-recapture method to serology results and self-report of past infection.ResultsOut of 1040 HCW included in the analysis, one-fourth (25.2%) received a positive result for anti-SARS-CoV-2 antibodies by ELISA test, the prevalence among women was 25.3% (95% CI: 22.5–28.4) and 24.6% (95% CI: 19–31.2) among men. The prevalence of anti-SARS-CoV-2 antibodies was the highest among respondents who declared home contact with a confirmed COVID-19 case, 43.9% (95% CI: 32.4–56.1). It was also elevated among those who indicated contact with patients with COVID-19, 32.5% (95% CI: 26.7–38.8) and business contacts, including at the workplace, 28.9% (95% CI: 22.5–36.3). The estimated cumulative incidence of COVID-19 infections in the population, using the capture-recapture method was 41.2% (95% CI: 38.1–44.2).ConclusionsHealthcare workers remained at increased risk of infection largely due to work-related contacts with infected patients, although home exposure was also common. Estimated cumulative incidence is higher than the antibody prevalence, which indicates the need to monitor HCW for possible immunity waning, also post-immunization immunity. Med Pr. 2022;73(2):109–23

Opis:
In order to mitigate the spread of COVID-19, in the early stages of the pandemic outbreak, postponing elective procedures was recommended all around the world. Outpatient care and dental care were limited to telephone advice and emergency services. Dental staff is particularly vulnerable to SARS-CoV-2 contraction, because of the inevitable contact with patients’ body fluids during aerosol-generating procedures. The implementation of diagnostic tests among ambulatory patients could improve the occupational safety among outpatient care personnel. The aim of this review was to introduce information regarding COVID-19 diagnostics with a particular focus on the methods which can be utilized in an outpatient and dental care setting. An online PubMed database review of articles on COVID-19 diagnostics, published on February 12–May 15, 2020, was conducted. Reverse transcription polymerase chain reaction is the gold standard in COVID-19 diagnostics, which determines if a person has an active infection. Unfortunately, its utilization in outpatient care is limited. Serological enzyme-linked immunosorbent assays identify people who were infected, including those who have had an asymptomatic infection, but they do not give sufficient information about the acute infection. Rapid serological assays developed to facilitate testing outside of laboratories, especially in dental offices, are not recommended by the World Health Organization to be used outside research settings, and they should not constitute the basis for clinical decision-making because of frequent false-negative results which may consequently contribute to personnel infections. Out of all available COVID-19 diagnostic methods, rapid serological assays seemed to be a method of choice in outpatient medical care. Unfortunately, their results turned out to be unreliable. The best methods to ensure the occupational safety of medical staff and to avoid cross-infections in outpatient care facilities include a thorough epidemiological interview, temperature measurement to rule out patients with an active infection, and the implementation of strict infection control procedures.

ObjectivesA pandemic triggers certain attitudes and behaviors, resulting in the need for adequate social support. The aim of the study was to determine the factors influencing the estimated risk of SARS-CoV-2 infection and to assess the need for social support in a group of medical students.Material and MethodsThe survey was conducted among 981 people, including 814 women and 167 men. For this purpose, a self-assessment survey with 22 multiple-choice questions was used. The online survey was conducted on March 20–April 2, 2020, which can be considered as the first stage of the pandemic in Poland.ResultsThe tested model for the subjective SARS-CoV-2 infection risk assessment explained 32.6% of the dependent variable variance (F(7.945) = 66.61, p < 0.001). The model for adherence to the recommendations for reducing the risk of SARS-CoV-2 transmission explained 9.5% of the variability (F(8.943) = 12.39, p < 0.001), and the model for an increased need for social support due to the SARS-CoV-2 epidemic explained 27.4% of the variability (χ2(8) = 12.17, p = 0.144).ConclusionsFactors important for estimating the risk of SARS-CoV-2 infection and the need for social support in the group of medical students were determined. The subjective assessment of the stress level, infection symptoms experienced and the field of study proved to be crucial.

ObjectivesThe aim of the study was to evaluate the clinical presentation and burden of SARS-CoV-2 infections among medical school physicians and residents, mainly young medical doctors. The awareness of COVID‑19 clinical manifestations can improve the early detection of mild cases, possibly reducing further transmission to colleagues and patients.Material and MethodsThe study was carried out in March–May 2020, involving medical school physicians in a teaching hospital in northern Italy, with a working population of 881 medical doctors. Data collection was performed using a structured form investigating clinical and epidemiological information.ResultsOne hundred sixty-two medical doctors contacted the Occupational Health Service reporting acute respiratory symptoms or close contact exposure to a confirmed COVID‑19 case. Among the confirmed COVID‑19 cases, most were male doctors during residency, and 85% presented a mild clinical picture. Fever (70.3%) and cough (51.4%) represented the most prevalent symptoms of COVID‑19. As revealed by the univariate analysis, the prevalence of real-time reverse transcriptase-polymerase chain reaction (RT-PCR) positivity increased with age (OR = 1.08, 95% CI: 1.02–1.14, p = 0.012), working in a COVID‑19 ward (OR = 3.33, 95% CI: 1.09–10.21, p = 0.031), presenting alteration or loss of smell/taste (OR = 10.00, 95%CI: 2.80–35.69, p < 0.001) and myalgia (OR = 3.20, 95% CI: 1.00–10.26, p = 0.046), while being a resident (OR = 0.20, 95% CI: 0.05–0.80, p = 0.030) was associated with reduced odds of being infected, compared to staff physicians. Age and loss of smell/taste were the only factors independently associated with RT-PCR positivity.ConclusionsThe majority of COVID‑19 cases showed a mild clinical syndrome, ranging from absence or paucity of symptoms to common cold or influenza-like symptoms. The findings of the present study increase the accuracy of the clinical diagnosis for the prompt identification and management of suspected COVID‑19 cases, being particularly useful during resurges of the SARS-CoV-2 pandemic.

Opis:
The outbreak of coronavirus disease 2019 (COVID-19) generated a huge pressure on health care systems worldwide and exposed their lack of preparation for a major health crisis. In the times of a respiratory disease pandemic, members of the dental profession, due to having a direct contact with the patients’ oral cavity, body fluids and airborne pathogens, are exposed to a great occupational hazard of becoming infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The authors carried out a systematic literature search using the main online databases (PubMed, Google Scholar, MEDLINE, UpToDate, Embase, and Web of Science) with the following keywords: “COVID-19,” “2019-nCoV,” “coronavirus,” “SARS-CoV-2,” “dental COVID-19,” “dentistry COVID-19,” “occupational hazards dentistry,” “ventilation,” “air disinfection,” “airborne transmission,” “hydrogen peroxide disinfection,” “UV disinfection,” “ozone disinfection,” “plasma disinfection,” and “TiO2 disinfection.” They included publications focused on COVID-19 features, occupational hazards for dental staff during COVID-19 pandemic, and methods of air disinfection. They found that due to the work environment conditions, if appropriate measures of infection control are not being implemented, dental offices and dental staff can become a dangerous source of COVID-19 transmission. That is why the work safety protocols in dentistry have to be revised and additional methods of decontamination implemented. The authors specifically advise on the utilization of wildly accepted methods like ultraviolet germicidal irradiation with additional disinfection systems, which have not been introduced in dentistry yet, like vaporized hydrogen peroxide, non-thermal plasma and air filters with photocatalytic disinfection properties. Due to its toxicity, ozone is not the first-choice method for air decontamination of enclosed clinical settings.

ObjectivesCoronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome virus 2 (SARS-CoV-2) had spread worldwide since December 2019 and became a pandemic in March 2020. The diagnosis of an active infection is based on the real-time reverse transcriptase-polymerase chain reaction (RT-PCR) from the nasopharyngeal swab specimen. The aim of the current analysis was to assess the usefulness of the rapid serological tests for diagnosing SARS-CoV-2 infections.Material and MethodsThe rapid serological tests detecting IgG/IgM antibodies for SARS-CoV-2 were voluntarily performed in asymptomatic employees of 2 companies. The examination was conducted at the date and time selected online by the study participants. The testing team consisted of 2 nurses collecting the samples and 1 doctor who interpreted the results. Each positive rapid test result was verified by an RT-PCR examination from a nasopharyngeal swab. The testing kits named Vazyme: 2019-nCoV IgG/IgM Detection Kit (Colloidal Gold-Based) were provided by the employer along with the manual and certificates.ResultsThe overall interest in testing among employees was below the employer’s expectations and reached 30% and 20% in each of the 2 companies, respectively. A total of 516 participants were included in the analysis. Ten positive results of the rapid tests were documented, including 7 for IgM and 3 for IgG antibodies. No positive result was confirmed by the detection of the genetic material of the SARS-CoV-2 by the RT-PCR examination.ConclusionsHerein, the authors demonstrated the uselessness of rapid serological tests performed in asymptomatic volunteers for diagnosing SARS-CoV-2 infections.

BackgroundThe aim of the study was to assess the state of knowledge of Medical University of Warsaw (MUW) students on COVID-19, modes of transmission and preventive measures.Material and MethodsThe study was conducted in October 2020. The participants were all the students attending classes at MUW – 8922 persons. All had completed the online training “Work safety and hygiene during COVID-19.” To assess their state of knowledge an online questionnaire was made available on the MUW e-learning platform. The questionnaire comprised 4 parts: (1) awareness of rules of hand hygiene, (2) medical aspects of COVID-19, (3) preventing SARS-CoV-2 infection transmission in health care facilities, and (4) preventing infection transmissions in the society.ResultsThe majority of students (93.9%) demonstrated a sufficient level of knowledge. The highest passing threshold was found on the medical programme (96.7% of students with satisfactory level of knowledge), dentistry (96.2%) and pharmacy (95.5%). The statistically significant factors that differentiated student results proved to be faculty (p < 0.001), study programme (p < 0.001), year of studies (p = 0.001), form of studies (p < 0.001). The participants most often showed full knowledge (100% correct answers in sub-area) of preventing infection transmissions in the society (93.3%) and medical aspects of COVID-19 (91.8%), less complete in terms of ways of preventing infection transmission in health care facilities (85.4%), and in particular hand hygiene rules (78.3%). All the variables characterizing academic status (study programme, faculty, year and form of studies) were statistically significant differentiating factors for students’ full knowledge in all of the 4 analyzed sub-areas, while students’ sex only in the sub-area of COVID-19 medical aspects.ConclusionsThere is a clear need for conducting systematic educational activities among students of all medical study programmes and assessing their level of knowledge in those areas that were identified as least frequently controlled, namely, hand hygiene and infection transmission in health care facilities.

Opis:
Objectives The diverse list of tasks and needs related to the SARS-CoV-2 pandemic may lead to different professional experiences in nurses working with patients infected with and not infected with SARS-CoV-2. The aim of the study was to measure the professional challenges of nurses working during the SARS-CoV-2 pandemic in Poland. Material and Methods The study was conducted in 2021 in a group of 151 nurses. The following scales were used: the Perceived Stress Scale (PSS-10), the General Self-Efficacy Scale (GSES), the Impact of Event Scale – Revised (IES-R), the Minnesota Satisfaction Questionnaire (MSQ-SF), the Areas of Worklife Survey (AWS) and the Maslach Burnout Inventory – Human Services Survey (MBIHSS). Results Nurses working with patients infected with SARS-CoV-2 showed a positive correlation between workload and emotional exhaustion (ρ = 0.26, p = 0.02), as well as positive correlations among control, community and depersonalization (ρ = 0.25, p = 0.02; ρ = 0.23, p = 0.04). Among nurses working with uninfected patients, positive correlations were found among control, community, fairness and emotional exhaustion (ρ = 0.40, p = 0.000; ρ = 0.41, p = 0.000; ρ = 0.25, p = 0.03), as well as correlations between control and depersonalization (ρ = 0.33, p = 0.01), and among control, community and personal accomplishment (ρ = 0.23, p = 0.05; ρ = 0.27, p = 0.02). Conclusions Nurses working during the SARS-CoV-2 pandemic with infected and uninfected patients both experienced a variety of psychosocial challenges in coping with the demands of their work, social relationships and personal life.

Opis:
Objectives The assessment of the prevalence of anti-SARS-CoV-2 antibodies in various professional groups is very important. Hence, the purpose of the following study was to analyze the seroprevalence of anti-SARS-CoV-2 antibodies among employees performing both medical and nonmedical professions before the launch of SARS-CoV-2 vaccination. Material and Methods The study was conducted among employers of 1 of the institutions: The Provincial Specialist Hospital of Władysław Biegański in Łódź, Poland, Radio Łódź and the Border Guards of Łódź Airport. Blood samples were collected in December 2020–February 2021. Patients were screened for the presence of SARS-CoV-2 antibodies. Simultaneously respondents were asked to complete a self-designed questionnaire including demographic data, detailed profession, history of SARS-CoV-2 infection and willingness to be vaccinated against COVID-19. Results Seroprevalence was significantly higher in the group of rural residents (p < 0.012), participants who declared previous COVID-19 infection (p < 0.001) and healthcare workers (HCWs) (p = 0.002), especially nurses (35.5%, p = 0.003) and medics worked in areas dedicated to COVID-19 than in other specialties (38.7% vs. 26.8%, respectively, p = 0.017). There was no association between the presence of antibodies and the gender (p = 0.118), age (p = 0.559) or BMI (p = 0.998). Conclusions Healthcare workers, in particular nurses, are at high risk of contracting COVID-19 in the workplace. Occupational infections can occur during occur not only during contact with the patient, but also with members of the medical team who do not show typical symptoms of the disease. Shortages in medical staff may also increase the number of infections among HCWs. Medical and hospital staff providing health services during the COVID-19 epidemic in Poland, may seek compensation in the event of consequences related to SARS-CoV-2 infection. The effectiveness of education and self-discipline in complying to safety rules among HCWs should also be constantly monitored.

Objectives Healthcare systems in European countries, including METEOR partner countries, are faced with the aging population, an increase in costs for innovative technologies and medication, a shortage of health professionals, and inequality in access to healthcare. Presented paper aimed to recognize and compare the functioning of healthcare systems between METEOR partner countries and simultaneously check if the current epidemiological situation of COVID-19 has some relationship with the number of medical staff, yearly gross domestic product, or documented percentage of fully vaccinated people. Material and Methods In the model of descriptive epidemiological study, available demographic, socioeconomic, and healthcare organizational data in the Netherlands, Belgium, Italy, and Poland were compared to the epidemiological situation of the COVID-19 pandemic (percentage of fully vaccinated people, incidence, and mortality) in all mentioned countries. Results Obtained data confirmed that the lowest number of physicians, as well as the life expectancy and gross domestic product per capita, is in Poland. Simultaneously, the lower number of medical staff and lower gross domestic product (GDP) correspond to higher mortality due to COVID-19. The percentage of fully vaccinated with the last dose of the primary series was also the lowest in Poland. Conclusions Obtained results confirmed that higher mortality due to COVID-19 in METEOR participants’ countries is related to a lower number of medical staff and weaker GDP. The worse situation was noted in Poland, a country with problems in the functioning healthcare system, including hospital care and a serious shortage of practicing medical staff.

Opis:
Virus-induced oral abnormalities, occurring especially in severe COVID-19 cases of hospitalized patients, have various characteristics and clinical features being, either directly or indirectly, related to SARS-CoV-2 infection. Deregulation of the immune system as a result of SARS-CoV-2 infection may lead to the impairment of the normal defense pathway in the SARS-CoV-2 positive patients. This scoping mini-review is aimed to critically appraise the existing evidence concerning the potential link between COVID-19 condition and abnormal manifestations within oral cavity, affecting oral mucosa, salivary glands and sensory elements. COVID-induced oral mucosa manifestations, with various clinical aspects, are likely to occur as coinfections and secondary symptoms, as immune system imbalance is per se a causative factor of secondary manifestations. Oral mucosal lesions related to SARS-CoV-2 infection do not seem to demonstrate gender predilection, with the average reported age around 50 years of age. They include mainly white and erythematous plaques, ulcers, blisters, petechiae. The affected intraoral areas were mainly: tongue, palate, lips, gingiva, and buccal mucosa. The “aggressive” therapies utilized to treat COVID-19, including drug interactions may aggravate or initiate OMLs pathologies. Neglected oral hygiene or partial or complete abandonment of oral hygiene during intensive hospitalization constitutes an independent factor promoting a wide range of oral pathologies. In addition, stress factor indirectly impairs functioning of the immune system. Oral mucosa lesions occurring in COVID-19 cases present with a wide variation of non-characteristic features. These intraoral, soft tissues abnormalities seem to be reversible and transient. A potential impact of severe oral pathologies to systemic health resulting from SARS-CoV-2 infection, along with associated poor oral hygiene should not be ignored, predominantly in seriously ill patients hospitalized in intensive care units.
