“…Apart from teaching theory, the allied health students have to be posted in injection/ immunization section to get practical exposure. 8,9 Comparatively, the overall knowledge regarding HBV vaccine among AHS is low than medical students. 14,15 Almost all students are having atleast got a single shot of HBV vaccine without knowing for what they are vaccinated.…”

“…The vaccine should be administered as the part of routine immunization schedule to all infants, HCWs, high risk occupational etc. 8,9 The importance of dosage, route of administration and individuals who are having chance of exposure to infectious moiety are eligible to receive the vaccines. 10 Hence, the present study has the main objective to assess the knowledge about HBV virus, modes of transmission and vaccination status among allied health professional students.…”

Background: Hepatitis B is endemic throughout the world and occupational exposure to HBV is very common among health care professionals. The main objective of the study was to assess the knowledge about HBV virus, modes of transmission and vaccination status.Methods: This was a prospective cross-sectional study which was carried out among 60 Allied Health Students in a tertiary care teaching hospital. The valediction of the questionnaire was done by a pilot study before starting the survey.Results: The respond rate was 96% and knowledge on causative agent was 93%, the organ affected 81.7% and modes of transmission were 70%. Awareness about vaccination and its importance were also assessed. The participants completed their three doses of vaccination were 12%, two doses 70% and not yet started was 18%. Awareness about other health care related infections through needle stick injuries and the risk percentage of contracting infection in the order of HIV, HBV and HCV was answered correctly by 81% of the participants.Conclusions: This study may help to impart the knowledge and awareness about HBV among the student population who lack knowledge regarding mode of transmission and fatal consequence. This study may further help the student population to inculcate health precautions during their clinical exposure in the near future.

“…This proportion is one of the highest rates of vaccination coverage among HCP with the reported prevalence in Iran [22,23] and other countries [17][18][19][20][24][25][26][27]. The reported rates of HBV immunization in HCP from both developed and developing countries varied widely [17][18][19][20][24][25][26][27]. Whereas, only 11.4% of Cameroonian HCP were fully vaccinated against HB [26], nearly all surgical nurses in Polish hospitals were immunized [20].…”

“…However, immunization of HCP against the risk of HBV is considered to be an additional most effective strategy for prevention and protection from HBV infection [6][7][8][9][10][11]. In this regard, several international agencies [16][17] and advisory committees on immunization practices (ACIP) in different countries [14,15], including Iran [16], recommended that all HCPs at risk of exposure to B/BF should be vaccinated against HBV infection. Moreover, guidelines suggest that vaccinated HCP should verify their immunity status within 1-2 months after completion of the course [5][6][7][14][15][16].…”

“…Despite these recommendations and effective protection profile provided by immunization among vaccinated personnel, international studies have reported suboptimal and varying vaccination coverage rates among HCP in different countries and even among various subgroups within the same country. For example, the reported rates of complete HBV vaccination was 24.7% in Africa [17], 63.4% in US [18], and 85-100% in EU countries including Poland [19,20]. In addition, results of studies on the immunogenicity of HBV vaccine among adults, including HCP, indicated 10-20% non-responsiveness among vaccinated adults [6][7][8]21].…”

Background: hepatitis B virus (HBV) and C virus (HCV) are among the leading causes of mortality worldwide. Health care personnel (HCP) are subjected to increased risk of these infections. Therefore, HBV vaccination and post-vaccination serologic testing (PVST) are recommended for them. Our Objectives in this study were investigate how well the vaccination guidelines for hospital HCPs were implemented. Moreover, the prevalence rates of HBV and HCV infections were calculated. To determine the presence of immunological memory, vaccinated personnel negative to antibody against HB surface antigen with one dose of HB vaccine were boosted. Methods: From 1 July to 30 November 2017, a cross-Sectional study among HCPs working in public hospitals were conducted. All HCPs from various professional categories potentially at risk of exposure to contaminated sources were included. The information was gathered via interview and self-administered questionnaire. The questions were focused on the demographic characteristics, HB vaccination and immunity status and time elapsed since initial vaccination series, and frequency of needelstick injuries during the past 12 months of their work. Moreover, the prevalence rate of HBV and HCV infections were calculated. To determine the presence of immunological memory, subjects negative to HBV seromarkers received a booster dose of the vaccine.Results: A total of 186 out of 766 participants were male and nurses comprised 71% of personnel. Although all HCP were vaccinated, 84% of them completed the course and less than 5% of them received PVST. According to the results, 0.78%, 4.6%, and 83% were serologically positive to HBV surface antigen, antibodies against HBV core, and S antigens, respectively. Approximately, 91% of seronegative participants responded to a booster dose and only 0.91% of the personnel was Anti-HCV positive.Conclusion: Most HCP received full HBV vaccination course. Although a minority did PVST, the HBV vaccine-induced long-term protection and HB vaccine booster were not required. Therefore, policies should be made to increase the rate PVST after immunization. According to the results, the HCV infection rate was low and thus pre-recruitment screening was not necessary.

Libya is a large country, ranking at fourth in terms of area both in the Arab world and the African continent (https://www.worldatlas.com/articles/which-are-the-10-largest-countries-of-africa-by-size.html). It is part of the World Health Organization–Eastern Mediterranean Regional Office (WHO–EMRO) region. Oil production is the main source of income which has transformed the country massively over the past 50 years and the healthcare system is one of the sectors that have improved significantly. The Health Act No (106), issued in 1973, guarantees free health services to all Libyans, with inevitable challenges regarding the delivery of adequate and sustainable services. The health system in Libya is a mix between the public sector and the private sector. The private sector is basically depending on funding through insurance companies and self-pay. It is not yet adequately developed but is striving and rapidly growing in the last two decades.The oncology services are accessible and available for all Libyans, most of the diagnostic and therapeutic facilities are of good standards and the modern treatments like immunotherapy and targeted therapies are also available. However, there were periods when the health care system—in general—was struggling to meet the increasing demand on health services and has seen considerable challenges, especially over the past few years due to the conflict, political, and economic instability of the country. This chapter covers the oncology care in Libya, describing the current state, challenges, and future directions.
