Introduction: Emerging Covid-19 disease has been described as an occupational disease especially for healthcare professionals. The aim of this study was to investigate the risk factors affecting the prevalence of Covid-19 disease in healthcare workers (HCWs).
Materials and Methods: In this review study, indexed studies from December 2019 to January 2021 with the keywords such as Covid-19, Coronavirus, Healthcare and Risk Factor were searched in the electronic databases of Web of Science, PubMed, Scopus and Google Scholar. Based on the search results 22 studies were included in the study.
Results: The risk factors for the outbreak of this disease among HCWs can be divided into 5 groups, including psychological, underlying, occupational, social and disease transmission risk factors. HCWs, as a high-risk group, in direct or indirect exposure to patients or infectious substances, they have a large share in transmitting the disease to others. For example, the probability of transmission from physicians to family members is 20.8% and to others is estimated at 25%. An important factor in the transmission of the disease is distance. Distances <20 cm in routine examinations and <5 cm in detailed examinations by physicians provide the potential for high transmission of the disease to ophthalmologists. Age, lack of hand care, comorbidities and autoimmunity, poor sleep quality, work stress, lack of PPE, workload and close contact to COVID-19 disease have been identified as risk factors for the transmission the disease.
Conclusion: HCWs, can by observing health tips and educating patients, will play an important role in controlling COVID-19 disease.

Introduction: COVID-19 is a highly contagious infectious disease caused by a new coronavirus that can be transmitted from person to person through close contact. The aim of the present study is to investigate new information in the field of COVID-19 immunology. Materials and Methods: The present study uses Google and Google Scholar search engines and articles indexed by reputable international scientific databases including Pub Med, MedLine, and the World Health Organization (WHO). In this study, published articles about COVID-19 and field of immunology were reviewed, and articles that did not have free access (Open Acess) and only access to abstracts were excluded from the study. Results: In total, studies have been suggested that the amount of cytokines such as IL-10, IL-7, IL-2, G-CSF, and TNF-α has been reported at high levels in patients. The ACE2 receptor is the target receptor for the Covid-19 virus, which binds to it after entering the lungs then IFN-I inhibit the primary replication and inhibition of the virus. Conclusion: After reviewing the articles, it was found that strengthening the immune system against viral infections is very important. The virus weakens the immune system by disrupting the production of type I interferon and reducing expression in the production of MHC-I, II. One of the best ways to fight COVID-19 is to get the right vaccine to boost immune system and produce T cells and cytokines.
