Background Camel trypanosomiasis or surra is of great concern in Somalia, since the country possesses the largest one-humped camel ( Camelus dromedarius ) population in the world. Civil war in Somalia has resulted in the destruction of educational, research, economic and social structures, making the country scores very low for most humanitarian indicators. Previous studies on detection of Trypanosoma species in Somali camels have only been performed during the 1990s using standard trypanosome detection methods (STDM). Considering the lack of state-of-the-art knowledge on camel trypanosomiasis in Somalia, the present study aimed to assess the prevalence of Trypanosoma spp. in three districts of Somalia. Methods A total of 182 blood samples from C. dromedarius from nomadic and dairy farms were evaluated using STDM, serological (CATT/ T. evansi ) and molecular (ITS1-PCR) methods. Results All samples were negative for Trypanosoma spp. by STDM. A total of 125/182 (68.7%, 95% CI: 61.4–75.3%) camels were seropositive for T. evansi by CATT/ T. evansi . Camels reared in nomadic system were more likely to be seropositive for T. evansi than those under dairy production system (OR: 5.6, 95% CI: 2.1–15.2, P  = 0.0001). Five out of 182 (2.7%, 95% CI: 0.9–6.3%) camels tested positive for Trypanosoma sp. by ITS1-PCR. Sequencing of the ITS1 region of the Trypanosoma species detected herein revealed that camels were infected with T. evansi and T. simiae . Conclusions Trypanosoma evansi is highly prevalent in camels from the Banadir region of Somalia, particularly in nomadic herds. To our knowledge, this is the first study to confirm infections with T. evansi and T. simiae in Somali camels through DNA sequencing. Our data highlight the need for implementation of adequate control measures aiming to reduce the impact on camel production in the country.

Background Fourteen-years after the last Rift Valley fever (RVF) virus (RVFV) outbreak, Somalia still suffers from preventable transboundary diseases. The tradition of unheated milk consumption and handling of aborted materials poses a public health risk for zoonotic diseases. Limited data are available on RVF and Brucella spp. in Somali people and their animals. Hence, this study has evaluated the occurrence of RVFV and Brucella spp. antibodies in cattle, goats and sheep sera from Afgoye and Jowhar districts of Somalia. Methods Serum samples from 609 ruminants (201 cattle, 203 goats and 205 sheep), were serologically screened for RVF by a commercial cELISA, and Brucella species by modified Rose Bengal Plate Test (mRBPT) and a commercial iELISA. Results Two out of 609 (0.3 %; 95 %CI: 0.04–1.2 %) ruminants were RVF seropositive, both were female cattle from both districts. Anti- Brucella spp. antibodies were detected in 64/609 (10.5 %; 95 %CI: 8.2–13.2 %) ruminants by mRBPT, which were 39/201 (19.4 %) cattle, 16/203 (7.9 %) goats and 9/205 (4.4 %) sheep. Cattle were 5.2 and 2.8 times more likely to be Brucella -seropositive than sheep (p = 0.000003) and goats (p = 0.001), respectively. When mRBPT-positive samples were tested by iELISA, 29/64 (45.3 %; 95 %CI: 32.8–58.3 %) ruminant sera were positive for Brucella spp. Only 23/39 (58.9 %) cattle sera and 6/16 (37.5 %) goat sera were positive to Brucella spp. by iELISA. Conclusions The present study showed the serological evidence of RVF and brucellosis in ruminants from Afgoye and Jowhar districts of Somalia. Considering the negligence of the zoonotic diseases at the human-animal interface in Somali communities, a One Health approach is needed to protect public health.

Ehrlichioses, caused by Ehrlichia species, are tick-borne diseases (TBDs) that affect animals and humans worldwide. This study aimed to investigate the molecular occurrence of Ehrlichia spp. in 530 animals (155 Dromedary camels, 199 goats, 131 cattle, and 45 sheep) in the Benadir and Lower Shabelle regions of Somalia. Blood DNA samples were tested for PCR targeting dsb and sodB genes of Ehrlichia spp. and PCS20 and map1 genes of E. ruminantium. The obtained sequences were submitted for phylogenetic analyses. Ehrlichia spp. were detected in 26.4% (140/530) of animals by dsb-PCR, with the highest prevalence in dromedary camels (54.8%), followed by cattle (29.8%), goats (7.0%), and sheep (4.4%). Dromedary camels, cattle, and goats had significantly higher infection odds compared to sheep (p < 0.05). Among dsb-PCR-positive samples, 76.9% (30/39) of cattle tested sodB-positive, while other species were negative. E. ruminantium was detected in 13.7% (18/131) of cattle by pCS20-PCR, but none were positive for the map1 gene. Phylogenetic analysis confirmed E. minasensis in camels, sheep, and goats and E. ruminantium in cattle, marking the first molecular evidence of E. minasensis in dromedary camels, sheep, and goats globally, and E. ruminantium in cattle from Somalia. These findings emphasize the need for further research on its economic and public health impact.

African animal trypanosomiasis (AAT) affects the livestock of 12.3 million Somalis and constrains their development and wellbeing. There is missing data on AAT in the country after the civil war of the 1990s. Therefore, this study has aimed to assess the prevalence of Trypanosoma spp. in 614 blood samples from cattle (n = 202), goats (n = 206) and sheep (n = 206) in Afgoye and Jowhar districts, Somalia using parasitological and molecular methods. Twenty-one out of 614 (3.4%; 95% CI: 2.1–5.2%) and 101/614 (16.4%; 95% CI: 13.6–19.6%) ruminants were positive for Trypanosoma spp. by buffy coat technique (BCT) and internal transcribed spacer 1 (ITS1)-polymerase chain reaction (PCR), respectively. Using ITS1-PCR, the highest prevalence was observed in cattle (23.8%; 95% CI: 18.4–30.1%) followed by goats (17.5%; 95% CI: 12.9–23.3%) and sheep (8.3%; 95% CI: 5.1–12.9%). A total of 74/101 (73.3%; 95% CI: 63.5–81.6%) ruminants were shown coinfection with at least two Trypanosome species. The four T. brucei-positive samples have tested negative for T. b. rhodesiense, by the human-serum-resistance-associated-PCR. Trypanosoma evansi, T. godfreyi, T. vivax, T. brucei, T. simiae and T. congolense were the Trypanosoma species found in this study. This is the first study on the molecular detection of Trypanosoma sp. in ruminants in Somalia. Further investigations and control measures are needed to manage Trypanosomiasis spreading in the country. Studies should also focus on the detection of T. b. rhodesiense in the country.

This study assesses the seroprevalence of Rift Valley fever (RVF) in ruminants in Dhobley, Somalia, following a 2021 outbreak in Kenya. Among 142 ruminants sampled, 4.9% were seropositive for RVF virus (RVFV) antibody, with IgM antibodies (1.4%) indicating recent exposure, though no cases were RT-PCR-positive. Unregulated livestock movement and limited surveillance pose significant risks for future outbreaks, underscoring the need for enhanced surveillance systems and One Health strategies.

Hemotropic mycoplasmas (hemoplasmas) are small pleomorphic bacteria that parasitize the surface of red blood cells of mammals. Hemoplasmas have been described in different species from the Camelidae Family, such as llamas and alpacas (South American camelids), but data on dromedary camels (Camelus dromedarius) are limited to a few reports. Somalia has one of the world's largest dromedary camel populations, and studies on hemoplasmas and tick-borne pathogens are lacking. Accordingly, this study aimed to screen dromedaries from Somalia for hemoplasmas by PCR-based assays. A total of 155 dromedary camel blood samples from 2 different areas of Mogadishu (n = 104) and the Lower Shabelle Region (n = 51) of the country were collected. All blood DNA samples were screened for hemoplasmas using a SYBR Green Universal Real-Time PCR (qPCR), nested PCR (nPCR), and conventional PCR (cPCR) assays targeting the 16S rRNA gene of hemoplasmas. Five out of 155 animals (3.23%; 95% confidence interval [CI]: 1.39–7.33%) were positive for hemoplasmas. A total of 346 (228 M, 117 F, and 1 nymph) ticks were collected from 79/155 (50.9%; 95% CI: 42.8–59.1%) dromedary camels with a mean of 4.4 ticks per animal. Ticks were identified as Rhipicephalus pulchellus (174/346; 50.3%), Hyalomma dromedarii (103/346; 29.8%), Hyalomma rufipes (35/346; 10.1%), Hyalomma marginatum (16/346; 4.6%), Rhipicephalus humeralis (14/346; 4.0%), Amblyomma lepidum (2/346; 0.6%), Amblyomma gemma (1/346; 0.3%), and Ornithodoros sp. (1/185; 0.5). This is the first study on the molecular screening for hemoplasmas in dromedary camels from Somalia and the first report of A. lepidum and R. humeralis in Somali dromedary camels.

Toxoplasma gondii and Neospora caninum infect a wide range of domestic and wild animals, including humans, in the case of T. gondii , and cause economic losses in livestock due to abortion and neonatal mortality. In Somalia, zoonotic diseases are concerning due to cultural practices and livestock’s economic importance, but surveillance is limited. This study aimed to determine the seroprevalence and molecular prevalence of T. gondii and N. caninum in Somali sheep, goats, and cattle. A cross-sectional study was conducted between December 2018 and January 2020 in Benadir and Lower Shabelle regions of Somalia. Blood samples were collected from 128 cattle, 184 goats, and 46 sheep. Serum samples were tested for anti- T. gondii and anti- N. caninum antibodies using IFAT, and PCR was performed on extracted DNA to detect T. gondii and N. caninum DNA. Overall, 106/358 (29.6%) animals tested positive for anti- T. gondii antibodies, with the highest prevalence in sheep (62.5%), followed by goats (30.4%) and cattle (15.6%) ( P  < 0.001). For anti- N. caninum antibodies, 13/358 (3.6%) animals tested positive, with cattle showing the highest prevalence (6.2%), followed by goats and sheep (both 2.2%). Co-seropositivity for both antibodies was found in cattle and sheep. Molecular detection of T. gondii DNA revealed a prevalence of 9/358 (2.5%), primarily in sheep (15.2%) and cattle at 1.6% while all goat samples tested negative. No samples were positive for the N. caninum Nc5 gene. This study reveals T. gondii and N. caninum prevalence in Somali ruminants, highlighting the need for better surveillance and control.

(1/185; 0.5). This is the first study on the molecular screening for hemoplasmas in dromedary camels from Somalia and the first report of A. lepidum and R. humeralis in Somali dromedary camels.

Human Immunodeficiency Virus (HIV) remains a significant public health challenge, particularly in low-resource settings, where limited knowledge contributes to its spread, especially among women facing socio-economic and educational barriers. This study examines the associations between misconceptions about HIV transmission and sociodemographic factors among Somali women. Identifying regions and groups with limited awareness will help prioritize targeted education and healthcare interventions, aligning with the National Strategic Plan (NSP). A multivariable Bayesian logistic regression model was used to analyze data from the 2018-2019 Somali Demographic and Health Survey (SDHS). This modeling approach was chosen for its ability to handle uncertainty and incorporate prior knowledge into the analysis. Bayesian adjusted odds ratios (BAORs) with 95% highest posterior density intervals (HPDIs) were calculated to determine significant associations between misconceptions and sociodemographic factors. The study found that 67.18% of women had misconceptions about HIV transmission. Significant factors associated with misconceptions included age, education, wealth, and internet usage. Women aged 30-34 (BAOR = 0.94, 95% HPDI: 0.90-0.98), 35-39 (BAOR = 0.94, 95% HPDI: 0.90-0.98), and 40-44 (BAOR = 0.93, 95% HPDI: 0.89-0.98), women with secondary education (BAOR = 0.92, 95% HPDI: 0.88-0.95), women with higher education (BAOR = 0.84, 95% HPDI: 0.79-0.88), women in the highest wealth quintile (BAOR = 0.90, 95% HPDI: 0.86-0.95), and women who had never used the internet (BAOR = 1.06, 95% HPDI: 1.03-1.09). This study highlights the critical need for targeted interventions to reduce misconceptions about HIV transmission among Somali women. Policies should focus on educating younger women, promoting female education, implementing region-specific health interventions, and enhancing internet access and digital literacy, particularly in rural areas, to improve HIV knowledge and support public health efforts.

Background Hepatitis B, C, and HIV infections are serious global  health concerns that affect both developed and developing nations. This study aimed to determine the prevalence of hepatitis B, hepatitis C, and HIV among pregnant women attending a tertiary hospital in Mogadishu, Somalia. Methods This retrospective study, conducted from January 2017 to December 2021 at the Somalia-Mogadishu Recep Tayyip Erdoğan Training and Research Hospital, assessed HBV, HCV, and HIV prevalence among pregnant women. Screening was performed using the VITROS ® 3600 Immunodiagnostic System. Data analysis was performed using IBM SPSS, with descriptive data presented as frequencies and percentages, and quantitative data as means and standard deviations. The χ² test or Fisher’s exact test was used for categorical data analysis. Result A total of 7,874 pregnant women were screened. After applying the exclusion criteria, 7,836 were tested for HBV, of whom 220 (2.8%) were positive for HBsAg. A total of 7,791 women were tested for HCV, and 33 (0.4%) were seropositive for anti-HCV antibodies. For HIV, 7,854 women were screened, and 16 (0.2%) tested positive for anti-HIV antibodies. These results indicate a moderate prevalence of HBV, a low prevalence of HCV, and a relatively low, but still concerning prevalence of HIV among pregnant women in this setting. HBsAg positivity showed statistical significance across all age groups ( p  ≤ 0.001), while anti-HCV positivity was significant for patients aged < 20 and 26–30 years ( p  = 0.011). Conclusion This study found lower HBV, HCV, and HIV prevalence among pregnant women in Mogadishu compared to previous studies, suggesting improvements in healthcare. However, these infections remain a public health concern. Strengthening antenatal screening, expanding hepatitis B vaccination, and ensuring universal access to treatment are crucial to reducing their impact on maternal and neonatal health in Somalia.
