Background: Monkeypox (Mpox) is a re-emerging infectious disease representing a new global challenge. It poses a substantial threat to countries, particularly those with a low number of cases. Due to its popularity as a tourist destination and its proximity to many African refugees, Egypt is potentially at risk of Mpox importation. Therefore, effective disease management necessitates healthcare workers (HCWs) to possess adept knowledge, along with a positive attitude and behavior. The study aimed to assess the knowledge, attitude, and perception of Egyptian HCWs and medical students towards human Mpox., Methods: The present cross-sectional study data was collected from participants between October and December 2022 via a questionnaire. The questionnaire comprised 31 questions in the knowledge section, 11 questions in the attitude section, and 14 in the perception section., Results: The present study involved a total of 1,034 HCWs and medical students. It was found that 55.3% of the participants demonstrated adequate knowledge about Mpox, whereas 44.5% and 39.8% of the respondents exhibited favorable attitudes and perceptions towards the disease, respectively. Binary logistic regression analysis revealed that adequate knowledge was significantly observed in ages older than 40 years ( p < 0.001), married participants ( p < 0.001), and doctors ( p < 0.001). The positive attitude was significantly observed among the male sex ( p = 0.045), urban residents ( p = 0.002), and nurses ( p = 0.002). Conversely, married participants (p = 0.013), doctors ( p < 0.001), and individuals employed in pharmacy and laboratory departments ( p < 0.001) experienced an increase in positive perception., Conclusion: Knowledge, attitude, and perception towards Mpox among Egyptian HCWs and medical students exhibit suboptimal levels. Addressing these gaps is crucial to controlling and effectively preventing disease transmission., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Amer, Nofal, Gebriel, Bedawy, Allam, Khalil, Elahmady, Nofal, Saeed, Shaltout, Behiry, Attia, Bahgat, Ali, Ahmed, Abdelrahman and Hammad.)

Background: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a constantly evolving virus, resulting in an increased burden on the existing COVID-19 vaccines. Healthcare workers (HCWs) are the first line of defense against the coronavirus disease 2019 (COVID-19) pandemic and have been prioritized among the risk categories receiving the COVID-19 vaccine. This work aimed to investigate the maintenance of antibody response of the Oxford−AstraZeneca vaccine (ChAdOx1/nCoV-19). Methods: Anti-spike immunoglobulin G (IgG) was measured at baseline point (immediately prior to vaccination) and 12- and 24-week (w) points following vaccination. Adverse reactions to the vaccine were reported. Participants were followed up for the incidence of COVID-19 during the 12 w interval between vaccination doses for 24 w after the second dose. Results: A total of 255 HCWs participated in the study. Prior to vaccination, 54.1% experienced COVID-19, 88.2% were seropositive after the first dose, while seropositivity reached 95.7% after the second dose. Following the first and second doses, the anti-spike IgG serum level was significantly higher in subjects with past COVID-19 than in others (p < 0.001 and =0.001, respectively). Conclusions: The Oxford−AstraZeneca vaccine is generally safe and provides a highly effective long-term humoral immune response against the Delta and Omicron variants of SARS-CoV-2.

Background: Healthcare workers (HCWs) are at a high risk for disease exposure. Given the limited availability of nucleic acid testing by PCR in low resource settings, serological assays can provide useful data on the proportion of HCWs who have recently or previously been infected. Therefore, in this study, we conducted an immunologic study to determine the seroprevalence of anti-SARS-CoV-2 antibodies in two university hospitals in Egypt., Methods: in this cross sectional study, HCWs who were working in SARS-CoV-2 Isolation Hospitals were interviewed. Estimating specific antibodies (IgM and IgG) against SARS-CoV-2 was carried out using an enzyme-linked immunosorbent assay targeting the Spike antigen of SARS-CoV-2 virus., Results: Out of 111, 82 (74%) HCWs accepted to participate with a mean age of 31.5 ± 8.5 years. Anti-SARS-COV2 antibodies were detected in 38/82 (46.3%) of cases with a mean age of 31 years and female HCWs constituted 57.6% of cases. The highest rate of seropositivity was from the nurses (60.5%), and physicians (31.6%) with only (7.9%) technicians. Only 28/82 (34.1%) HCWs reported previous history of COVID19. We reported a statistically significant difference in the timing of exposure (p = 0.010) and the frequency of contact with COVID-19 cases (p = 0.040) between previously infected and on-infected HCWs. Longer time of recovery was reported from IgG positive HCWs (p = 0.036)., Conclusion: The high frequency of seropositive HCWs in investigated hospitals is alarming, especially among asymptomatic personnel. Confirmation of diseased HCWs (among seropositive ones) are warranted., (Copyright © 2021 The Author(s). Published by Elsevier Ltd.. All rights reserved.)

Introduction: The ongoing coronavirus-disease-19 (COVID-19) pandemic had a variable history with differences in its various stages. This study evaluates the status of knowledge, perception, and confidence about COVID-19 preventive measures during the first wave of the COVID-19 pandemic among healthcare workers (HCWs) in Egypt., Methods: A cross-sectional study was conducted during the first wave of the COVID-19 pandemic, in July 2020, in Egypt. An-online-based questionnaire was used to collect data. It included items to record demographic data, and an assessment of knowledge, the perception of healthcare facilities preparedness, and HCW confidence about applying infection prevention measures., Results: A total of 465 responses were analyzed. HCWs' mean age was 36.76 ± 9.57 years, 94.2% (n=438) had an adequate level of knowledge, 31% (n=144) had an adequate perception level, and 39.4% (n=183) had an adequate confidence level. The main source of information was international organizations' websites 46.5% (n=216). The main barriers to applying preventive measures were the overcrowding of patient care areas 73.1% (n=339), and limited infection control supplies 68% (n=316). Factors associated with COVID-19 among HCWs were COVID-19 infected family members (OR: 5.86), inability to protect themselves and their families (OR: 5.73), uncertainty about the available hand hygiene supplies (OR: 3.76), male gender (OR: 3.07), and single HCWs (OR: 2.88)., Conclusions: Although the majority reported an adequate knowledge level, lower rates of adequate perception and confidence were observed. Revision of preparedness plans in different facilities should be further studied. Psychological support and gender differences should be considered in response programs., Competing Interests: Conflicts of interest: All authors – none to declare., (GERMS.)
