Measles, Mumps ,and rubella (MMR) are serious diseases that can lead potentially to disability and death. The study aimed to determine seroprevalence rates of antibody levels against MMR among Libyan children at school entry. This was a cross sectional study undertaken in Tripoli, from August to September 2016. Children of school-entry age (> 5 to ≤ 7 years) were randomly recruited at vaccination centers. Sera were tested for antibodies againstMMR. Data analyzed by SPSS program version 20. Out of 546 children, 290 were males. IgG antibodies against measles, mumps, and rubella were positive in 513 (94%), 436 (80%), 538 (98.5%) children, respectively. Seropositivity rates in Libyan children at school entry is protective and this is similar in so many other studies. This indicates that MMR vaccine program is effective in strengthening herd immunity in the Libyan community. arabic 19 English 111

Objective: In Libya, no pertussis booster doses are administered to children after 18 months of age. In light of evidence of waning of vaccine-induced immunity to pertussis, this study aimed to evaluate the waning of immunity in vaccinated school-entry age children, as measured by susceptibility to infection at population level. For this purpose, IgG and IgA levels were measured as markers of recent (infection in the last 6 months) and non-recent infections (infection in the last 12 months). Material and Methods: This was a cross sectional study undertaken in Tripoli, in February 2015. Children of school-entry age (> 5 to ≤ 7 years) were recruited on convenience basis at vaccination centers. Sera were tested for antibodies to pertussis. Results: Samples from791 children (421 males and 370 females, mean age 6.50 were tested). All of the participants had received 4 doses of Whole cell pertussis containing vaccine in the first 2 years of life. The prevalence of recent and non-recent pertussis infection were 4.8% and 2.5%, respectively. The proportion of children with undetectable level of IgG was 76.1%. Conclusion: The findings of this study showed significant circulation of Bordetella pertussis among vaccinated children by school-entry age. The circulation of B. pertussis in this population may be an indirect sign of waned immunity, which is simply corroborated by the absence of detectable antibodies in 76.1% of the children. arabic 14 English 76

Objective Healthcare workers, particularly those working in departments that provide care for patients with coronavirus disease 2019 (COVID-19), are at a higher risk of this contagious disease than those who work in other departments. The aim of this study was to assess the psychological status of healthcare workers during the COVID-19 outbreak, which has compounded Libya's existing civil war-related problems. Methods A multi-center cross-sectional survey on depressive symptoms, anxiety symptoms, and abuse was conducted. The Hospital Anxiety and Depression Scale (HADS) was used to measure the prevalence of anxiety and depressive symptoms among healthcare workers. Results The data of 745 eligible healthcare workers from 15 hospitals were analyzed. Depressive and anxiety symptoms were compared to the basic characteristics of the participants to determine the association. A total of 420 (56.3 … arabic 17 English 93
