We performed a retrospective cohort study of 311 pediatric patients visiting Bascom Palmer Eye Institute (BPEI) ED between March and May 2020 to quantify the effect of the coronavirus (COVID-19) on ophthalmology care utilization. In our study, pediatric ED visits declined by half at the onset of the pandemic in March. The number of visits reached the lowest point in early April and increased to 48% of the pre-COVID volume by the end of May. Despite changes in volume, patient demographics and clinical diagnoses were relatively consistent throughout the pandemic.A previous study based on mitochondrial DNA markers reported the presence of Fasciola hepatica in Algeria. However, a precise species identification is still required. In this report, a total of 68 Fasciola isolates, collected from high-plateau (Bordj-Bou-Arreridj) and steppe (Djelfa) areas of Algeria, were identified at the species level by multiplex PCR and PCR-restriction fragment length polymorphism (RFLP) for nuclear phosphoenolpyruvate carboxykinase (pepck) and DNA polymerase delta (pold), respectively. The result of the multiplex PCR conflicted with that of the PCR-RFLP; however, subsequent nucleotide sequencing of pepck clearly showed that all isolates should be classified as F. hepatica. The two mitochondrial markers, NADH dehydrogenase subunit I (nad1) and cytochrome c oxidase subunit 1 (cox1), revealed a close relationship between the parasite populations from the plateau and those from the steppe. A dispersal direction from the high plateau to the steppe was indicated because the former population was more diversified than the latter. Moreover, these populations were more closely related to populations from Spain than those from Egypt or Afghanistan. Given the population characteristic of F. hepatica in Spain and the history of catt
