Abstract: Coronavirus disease 2019 (COVID-19) contact tracing and malaria reactive case detection (RACD) are effective strategies for disease control. The emergence of the COVID-19 pandemic and the global attention COVID-19 has received in the recent past and present has h ered malaria control efforts. Among these are difficulties in finding and treating malaria-infected in iduals in hypoendemic settings in the community, due to lockdown restrictions by countries. It is common knowledge that malaria cases that cannot be identified remain untreated. To sustain the gains made in malaria control, we proposed a two-pronged hybrid approach for COVID-19 contact tracing and malaria RACD in communities with COVID-19 and malaria coinfections. Such an approach would equally factor the burden of malaria cases and COVID-19 to support an effective strategy for responding to current and future pandemics.

Abstract: Trichomonas vaginalis is the causative agent for the most prevalent non-viral sexually transmitted infection (STI) among women of child-bearing age. In Ghana, although the infection is prevalent, there is a dearth of data on the risk factors and symptoms associated with T. vaginalis infection. This study was conducted on 492 women visiting gynaecological and STI clinics in the Volta Region (VR) and Greater Accra Region (GAR) in southern Ghana. Wet mount microscopy and polymerase chain reaction (PCR) were used to diagnose T. vaginalis infection. Infection prevalence was 13.2% and 18.1% by WMM and PCR, respectively. Diagnosis by PCR was significantly more sensitive (McNemar's test, p=0.0003). The regional prevalence of T. vaginalis infection by PCR was 21.7% in the VR and 12.8% in the GAR. There was a significant difference in prevalence between the two regions (Fisher's exact test, p=0.02). T. vaginalis infection was associated with vaginal itch (odds ratio [OR]=1.71, p=0.04) and a history of engaging in oral sex (OR 1.90, p=0.04). A high prevalence of T. vaginalis infection was recorded among women visiting gynaecological and STI clinics in southern Ghana. There was no consistent association of infection with any recorded clinical signs and no clear risk factors for infection were identified.

Abstract: To identify the gastrointestinal helminths of veterinary, zoonotic and public health importance in farmers and their ruminant livestock in Ghana, faecal s les were collected from 95 farmers and their livestock (cattle = 328, sheep = 285 and goats = 217) and examined by microscopy and/or molecular techniques. Overall, 21 farmers tested positive for at least one gastrointestinal helminth, 80.9% of which were single infections and 19.0% co-infections. The parasites identified in the farmers consisted of hookworms (n = 13) (9 were Necator americanus and the other 4 could not be lified by PCR), Trichostrongylus spp. (n = 9), Schistosoma mansoni (n = 1), Schistosoma haematobium (n = 1) and Diphyllobothrium latum (n = 1). In livestock, strongylid nematodes were dominant (56.6%), followed by Par histomum spp. (16.9%), Dicrocoelium spp. (7.1%), Thysaniezia spp. (5.8%), Trichuris spp. (3.3%), Moniezia spp. (3.1%), Fasciola spp. (2.8%), Toxocara spp. (1.1%) and Schistosoma spp. (0.2%). Genotyping of Trichostrongylus spp. in the farmer's stools identified six T. colubriformis similar to T. colubriformis detected in cattle, sheep and goats in the study, two Trichostrongylus spp. with 98.3% and 99.2% genetic similarity to T. probolurus respectively and one Trichostrongylus spp. which showed 96.6% similarity to both T. probolurus and T. rugatus. Trichostrongylus axei was also identified in cattle, sheep and goats. This is the first molecular characterisation of Trichostrongylus spp. in Ghana and the species identified in the present study suggests zoonotic transmission from cattle, sheep and goats. Further studies involving larger numbers of farmers and their household members are essential to understand the transmission dynamics and impact of these parasites on farming communities in Ghana.
