Abstract Background: Epizootic haemorrhagic disease (EHD) is a vector-borne viral disease of domestic and wild ruminants. Epizootic haemorrhagic disease virus (EHDV) is transmitted by Culicoides spp. EHDV is a member of the Orbivirus genus within the Reoviridae family. It shares many morphological and structural characteristics with other members of the genus, such as the bluetongue virus, African horse sickness virus, and equine encephalosis virus. Aims: The purpose of our study was to investigate the epidemiological situation of EHDV in Libya in order to gain some knowledge about the presence of this virus in the country. Methods: In this study, we investigated the seroprevalence of EHDV in Libya, testing 855 blood samples collected during 2015. The samples were collected from domestic ruminants (cattle, sheep, and goats) originating from 11 provinces of Libya. Sera were tested by competitive enzyme-linked immunosorbent assays and positive samples confirmed by serum neutralization test. Results: The overall seroprevalence of EHDV was estimated to be 4% (95% confidence intervals = 2.8%–5.4%). Small ruminant seroprevalence was significantly (p = 0.016) higher than that found in cattle. Neutralizing antibodies against EHDV-6 were detected in a sheep from the western region of Libya. Conclusion: This study suggests that EHDV has circulated or is circulating in Libya, and sheep could play an important role in the epidemiology of EHDV, and the virus may still be circulating in North Africa. Keywords: EHD, EHDV-6, Seroprevalence, Libya.

There were only 75 confirmed cases of coronavirus disease 2019 (COVID-19) reported in Libya by the National Center for Disease Control during the first two months following the first confirmed case on 24 March 2020. However, there was dramatic increase in positive cases from June to now; as of 19 November 2020, approximately 357940 samples have been tested by reverse transcription polymerase chain reaction, and the results have revealed a total number of 76808 confirmed cases, 47587 recovered cases and 1068 deaths. The case fatality ratio was estimated to be 1.40%, and the mortality rate was estimated to be 15.90 in 100000 people. The epidemiological situation markedly changed from mid-July to the beginning of August, and the country proceeded to the cluster phase. COVID19 has spread in almost all Libyan cities, and this reflects the high transmission rate of the virus at the regional level with the highest positivity rates, at an average of 14.54%. Apparently, there is an underestimation of the actual number of COVID-19 cases due to the low testing capacity. Consequently, the Libyan health authority needs to initiate a large-scale case-screening process and enforce testing capacities and contact testing within the time frame, which is not an easy task. Advisably, the Libyan health authority should improve the public health capacities and conduct strict hygienic measures among the societies and vaccinate as many people against COVID-19 to minimize both the case fatality ratio an

Background: The pre-vaccination survey is considered an important tool for assessing and evaluating knowledge, attitudes and determine vaccine hesitancy. Throughout many decades the world had faced a challenge in fighting against the endemic, epidemic, and pandemic diseases that have been emerging and re-emerging special those that constitute a great potential risk on humanity’s life. Still, after more than one year and half of scientific milestones of COVID-19 pandemic, there are many countries scarifying and struggling to mitigate the impacts of SARS-CoV-2 among their societies. Objectives: Our study was conduct to address, assessing and evaluate COVID-19 vaccine literacy (VL) prior to and during the vaccination campaign in Libya. Material and Methods: The cross-sectional questionnaire survey was conducted during April 2021 one week prior COVID-19 vaccination campaign in Libya. All relevant data was obtained and collected by online and face-to-face interview. The sampling method with an online Microsoft form questionnaire resulted in collecting only 33 valid questionnaires. Further, the survey carried out also during vaccination campaign however, any participants who had already taken the COVID-19 vaccine were not indorsed in questionnaire survey. Results: A total of 243 participants were involved in this study. The overall response rate (45.6%). This study enrolled (58.8%) and (41.2%) of participants from male and female respectively. Considering the age classes, the results revealed that (35%, 18-30 year), (43.6%, 31-50 year), (18.5%, 51-65 year) and (>65 year, 2.9%). The results revealed that, 29.2% (95% Confidence Interval (CI): 25%-33.44%) of the respondents were confirmed or suspected COVID-19 infection, while and 70.8% (95% CI: 66.56%-75%) participants were not sure if they had contracted the virus. Regarding the recurrent COVID-19 infection, our questionnaire survey reported that, at least 5.8% (95% CI: 3.60%-7.92%) of the respondents had got infected twice by SRAS-CoV-2. Regarding the currently available COVID-19 vaccines (Sputnik V, AstraZeneca and Sinovac) in the country, the vast majority (43.2%) of the participants, they would like to prefer the Sputnik V, followed by (19.3%) AstraZeneca and (2.5%) Sinovac vaccines, while (35%) of the respondents refused to be vaccinated by three of these vaccines that have been provided by the Libyan healthy authorities under the supervision of NCDC. A proximately 33% (95% CI: 28.56%-37.28%) of the respondents refused to be vaccinated due to mistrust in the vaccine safety. Clearly, the vaccine safety was the main cause for the refuse and delay time of the vaccination from the most of the population. Conclusion: Our study highlights that, the vaccine hesitancy is underestimated issue in Libya, and clearly there is misleading and misinformation about SARS-CoV-2 from unauthorized media sources. According to the metadata analysis of high efficacy, safety and successes of COVID-19 vaccines for mitigate and minimize both the case fatality rate (CFT) and transmission rate across the entire of the global, still there is a controversies around potential safety concerns of the COVID-19 vaccines. Urgently, the Libyan healthy authority needs to enforce the public health education about vaccine safety, and Libyan healthy authorities should be implement an effective vaccination strategies that complement with international standard criteria for the vaccination policy to improve the vaccination efficacy and the vaccine coverage rate. Consequently, The Libya national deployment and vaccination plan for the COVID-19 vaccine should implement National Immunization Technical Advisory Group (NITAG) in every municipality for collecting and processing information, and producing periodic reports during COVID-19 vaccination campaign.
