Are health-care workers really at risk of HCV infection?

BACKGROUND: Hepatitis C virus (HCV) infection is a global public health issue. Health care workers (HCWs) are particularly at risk. Nigeria hepatitis prevention policy aims to achieve country wide elimination of hepatitis through early detection using mass screening with life-style modifications of “at risk population” which are key preventive strategies. AIM: To determine the seroprevalence of HCV infection among HCWs in a large regional referral hospital in Nigeria METHODS: A hospital-based descriptive cross-sectional study (hepatitis mass screening) was done at the University of Nigeria Teaching Hospital, Enugu, Nigeria between July and August 2016. Non-randomised sampling was used. Blood samples were assayed for antibodies to HCV. Data on knowledge, risk factors and mode of transmission were collected using a structured, pre-validated, pretested, questionnaire and analysed using SPSS version 20. RESULTS: A total of 3132 out of 5144 (60.9%) HCWs participated in the study. The seroprevalence of hepatitis C among UNTH staff was 0.90% (28/3132). The mean knowledge score of 68.95% ± 24.23 and 56.70±17.25 translates to fair knowledge level about mode of transmission and risk of transmission of hepatitis C among HCWs, respectively. There was no reported case of hepatitis B and C co-infection. Females HCWs had highest sero-prevalence for HCV 17/5144 (0.33%) (P = 0.164, AOR= 1.76, 95%CI =0.431-2.413) CONCLUSION: This study found a low seropositivity of HCV among HCWs. A pointer to the possible success of the hospital-based education awareness programme, an implementation of Nigeria’s national hepatitis prevention policy.

Abstract Background Health care workers are at significant risk for infection with the novel coronavirus SARS-CoV-2. Methods We utilized a point-of-care, lateral flow SARS-CoV-2 IgG immunoassay (RayBiotech) to conduct a seroprevalence study in a cohort of at-risk health care workers (n=339) and normal-risk controls (n=100) employed at an academic medical center. To minimize exposure risk while conducting the study, consents were performed electronically, tests were mailed and then self-administered at home using finger stick blood, and subjects uploaded a picture of the test result while answering an electronic questionnaire. We also validated the assay using de-identified serum samples from patients with PCR-proven SARS-CoV-2 infection. Results Between April 14th and May 6th 2020, 439 subjects were enrolled. Subjects were 68% female, 93% white, and most were physicians (38%) and nurses (27%). In addition, 37% had at least 1 respiratory symptom in the prior month, 34% had cared for a patient with known SARS-CoV-2 infection, 57% and 23% were worried about exposure at work or in the community, respectively, and 5 reported prior documented SARS-CoV-2 infection. On initial testing, 3 subjects had a positive IgG test, 336 had a negative test, and 87 had an inconclusive result. Of those with an inconclusive result who conducted a repeat test (85%), 96% had a negative result. All 3 positive IgG tests were in subjects reporting prior documented infection. Laboratory validation showed that of those with PCR-proven infection more than 13 days prior, 23/30 were IgG positive (76% sensitivity), whereas 1/26 with a negative prior PCR test were seropositive (95% specificity). Repeat longitudinal serologic testing every 30 days for up to 4 times is currently in progress. Conclusion We conducted a contact-free study in the setting of a pandemic to assess SARS-CoV-2 seroprevalence in an at-risk group of health care workers. The only subjects found to be IgG positive were those with prior documented infection, even though a substantial proportion of subjects reported significant potential occupational or community exposure and symptoms that were potentially compatible with SARS-COV-2 infection.

Occupational Infection

Introduction. Health care workers are at risk of infection with the SARS-CoV-2 virus. However, many aspects of the professionally conditioned COVID-19 are still poorly understood. The aim of study is to conduct a brief review and analysis of scientific data on the prevalence, features of clinical and laboratory COVID-19 syndromes in medical professionals. To evaluate the structure of post-COVID syndrome in health care workers who are observed in a large multidisciplinary medical organization that has a center for occupational pathology. To present the current state of the problem of examination of the connection of COVID-19 with the profession and admission to work in conditions of high risk of SARS-CoV-2 infection. Materials and methods. At the first stage, a brief review of the literature on the problem of COVID-19 in health care workers was performed, at the second - a single-center observational prospective study of COVID-19 convalescents. The main group consisted of health care workers (n=203), the comparison group - people who do not have occupational health risks (n=156). The groups were comparable in demographic characteristics. The work experience of the medical staff was 15 (5; 21) years. Of the participants in the main group, 20.2% worked in hospitals, and 79.8% in outpatient institutions. Three of the participants (1.5%) were employees of specialized COVID hospitals. Doctors were 25.6%, secondary medical personnel - 51.7%, junior medical and technical personnel - 22.7%. A severe form of COVID-19 was suffered by 25 (12.3%) people, after the artificial ventilation of the lungs (AVL) - two participants. The observation time is 60 days. Statistical analysis included standard methods of descriptive statistics, determination of relationships by the method of logistic regression. The significance level is p<0.05. Results. Most of the known data on COVID-19 in health care workers is obtained in cross-sectional studies. The possibility of occupational infection has been sufficiently proven. The risk probably depends on the work performed and is higher in conditions of direct contact of medical personnel with adults, potentially infected patients, but not in a specialized hospital. It is possible that the course of COVID-19 in health care workers differs from the general population of patients there is evidence of a greater frequency of weakness and myalgia. Studies of the features of post-COVID syndrome in health care workers in available sources could not be identified. According to the results of their own research, health care workers who had experienced COVID-19 had a higher frequency of central thermoregulation disorders, arrhythmias, heart failure, panic attacks and depression. Conclusions. Health care workers are at risk of COVID-19. Professionally conditioned post-COVID syndrome is characterized by the frequency of violations of the central mechanisms of thermoregulation and arrhythmias. COVID-19 in health care workers meets the definition of occupational disease.
