Background: Coronavirus-19 (COVID-19) is a novel, highly infectious, and potentially fatal communicable pandemic disease. It has taken longer to reach Africa than the other continents. Objective: To examine the pattern of COVID-19 in the Horn of Africa countries from March to December 2020. Methods: A prospective cross-sectional study in which the total number of daily reported cases and deaths were collected from the official website of the World Health Organization (WHO) and Worldometer. Data were standardized based on the total population provided by World Population Prospects 2020 per million. Data sources of WHO reports and governmental reports from March to December 2020 were analyzed in this study. Data extraction was done using the microsoft excel spreadsheet tool, variables relating to the countries were computed in terms of frequencies and percentages. Results: The findings revealed that as of 31st December 2020, 136,129 (7590 per million) cases were reported from the four countries in the Horn of Africa. The overall case fatality rate (CFR) in the Horn of Africa was 1.14%. The majority of the cases were reported from Djibouti (77.20%), followed by Ethiopia (14.07%), Eritrea (4.87%), and Somalia (3.86%). The highest case fatality rate (0.81%) was from Djibouti, and the lowest (0.01%) was from Eritrea. Conclusions: The epidemiological pattern of COVID-19 among the Horn of African countries seems to have slow progress, given the prevalence of the new infections remains low, and the death toll seems stable throughout the study periods, except for Djibouti. Hence, the prevention control measures implemented in the countries should be further strengthened and supported. It is recommended that relevant stakeholders responsible for tackling the COVID-19 pandemic should put up measures to curb the spread of the virus in the region and set up a crisis management system to combat future pandemics.

The microsporidian fungal pathogen Enterocytozoon bieneusi is a unicellular parasite that infects humans and various animals, including pigs. Currently, there are few data on E. bieneusi infection a in diarrheic pigs in Chongqing and Sichuan Provinces, China. This study aims to determine the prevalence and genotype distribution of E. bieneusi in diarrheic pigs. In total, 514 fecal samples from diarrheic pigs were obtained from 14 large-scale farms in Chongqing and Sichuan Provinces (326 suckling pigs, 17 weaned pigs, 65 fattening pigs, and 106 sows). To identify the E. bieneusi genotypes, genomic DNA was isolated from the samples and tested by nested PCR, targeting the internal transcribed spacer region of the rRNA followed by DNA sequence analysis. The overall prevalence of E. bieneusi was 79.8% (410/514), with rates of 84.9% (90/106) in sows and 64.7% (11/17) in weaned pigs. We found 61 different genotypes, including seven known genotypes (E, F, CHG1, Peru8, CAF1, B, and BEB17) and 54 novel genotypes. These 54 new genotypes are variants of eight known genotypes (SDD2, A, B, HLJD-IV, PigSpEb1, O, JLD-I, and BEB17) based on their sequence similarities. Phylogenetically, all of the identified genotypes clustered with counterparts belonging to Group 1 and Group 2 of E. bieneusi. Therefore, we found a higher prevalence of E. bieneusi in sows than in preweaned and weaned pigs. These findings indicate that diarrheic pigs could be a potential reservoir host, which can contaminate the environment and be a source of microsporidia in humans and other animals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
