Cutaneous leishmaniasis (CL) is an endemic parasitic infection in the Mediterranean region, including Libya and its Al-jabal Al-gharbi province. We aimed at studying the occupational relevance as well as other epidemiological aspects of CL. We investigated 140 CL cases who attended at Gharyan outpatient polyclinic during a period of 6 months in 2009. CL infection was clinically diagnosed and confirmed by demonstration of Leishmania parasites on smears from lesions. Our findings showed that males were more affected than females (P=0.04), and people above 10-years were more affected than younger ones (P=0.0001). A significant percent of CL cases belonged to Al-Kawasem subprovince (P=0.0001). Farm-related activities were the most frequent occupations among CL cases (P=0.04). In addition to farm workers, housewives and students are at risk groups since they are engaged at farm activities. Moreover, those who have occupations that require staying outdoors for a part of night, e.g., policemen, are also at risk. Compared to children, adult CL patients had multiple lesions (P=0.001) that were more prevalent in their upper and lower extremities than the face (P=0.0001). We conclude that CL is a major health problem in Al-jabal Al-gharbi province of Libya. The presence of rodents and sandflies makes it a suitable environment for Leishmania to spread in an endemic epidemiological pattern. Being engaged in farming activities or outdoor occupations increases the risk of infection. Various clinical patterns of CL suggest the presence of more than 1 species of Leishmania at Al-jabal Al-gharbi province. We propose that the 2 species responsible for CL in this area are L. major and L. tropica. Further investigations to identify the leishmanial species responsible for CL at Al-jabal Al-gharbi together with adoption of preventive and control programs are needed.

Aims: Studying the post-vaccination adverse health events is crucial to determine the confidence and acceptance of the public to the newly-developed COVID-19 vaccines. The present study aimed to investigate the prevalence rates of the adverse health events experienced by the recipients of COVID-19 vaccines in Saudi Arabia. Methodology and results: A cross-sectional study was conducted in October 2021 using a google form of an online self-administered questionnaire sent via different social media platforms for recruiting participants from southwestern Saudi Arabia. The questionnaire was prepared by medical and public health professionals and then translated into Arabic, pilot-studied and validated. Among the 453 Saudi adults who participated in the study with at least one dose of the COVID-19 vaccine, about (77.9%) were males aged 25.5 ± 10.6 years. Most of the participants were college students living in the Makkah region. Nearly 68.3% reported post-vaccination adverse events, such as injection site pain/swelling (91.9%), fatigue (67.9%), bone and muscle pain (65.2%) and flu-like symptoms (58%). The type of vaccine was significantly associated with the development of adverse events p=0.002 (OR of Pfizer-BioNTech versus AstraZeneca: 0.33, 95% CI: 0.18-0.61). Additionally, ageing of more than the 3rd decade, male gender and being married were significantly associated with lower rates of reporting post-vaccination adverse events. Conclusion, significance and impact of study The development of COVID-19 vaccine-related adverse health events had no significant associations with residence, education, occupation, BMI, chronic diseases or smoking. However, age, gender, marital state and vaccine type may be considered significant predictors for developing post-vaccination adverse reactions.
