Expression patterns of plasma microRNAs in patients with cervical cancer from two teaching hospitals in Ghana.

Aim: Early cervical cancer diagnosis is a global challenge that needs to be addressed by the discovery of less invasive diagnostic and prognostic approaches. Circulating miRNAs are stable in plasma and their diagnostic potentials have been elucidated in some cancers. Therefore, in this cross-sectional study, we determined the patterns of expression of 7 selected circulating microRNAs that differ between patients with cervical cancer receiving therapy, patients with cervical not on therapy and healthy females.

Is Ghana Prepared for Another Arboviral Outbreak? Evaluating the 2024 Dengue Fever Outbreak in the Context of Past Yellow Fever, Influenza, and COVID-19 Outbreaks.

Arboviruses are a growing concern in many nations. Several reports of arboviral outbreaks have been recorded globally in the past decade alone. Repeated arboviral outbreaks in developing countries have consistently highlighted vulnerabilities in disease surveillance and response systems, exposing critical gaps in early detection, contact tracing, and resource allocation.

Practical norms in emerging infectious disease control: lessons for transnational collaboration from a suspected newly emerging zoonosis outbreak in Ghana.

Concern around the emergence of zoonoses with pandemic potential has fuelled significant foreign engagement with domestic infectious disease surveillance and response systems across Africa. These international efforts at augmentation have likely been hampered, however, by an inattention to how such systems actually manifest on the ground and the critical activities and undertakings that take place outside of official structures and protocols. Such deviations from official protocols have previously been treated as inherently detrimental to public service delivery.

HIV-1 diagnostic, prognostic and ART-resistance detection potential of selected MiRNAs.

Background: The global HIV prevalence estimate at the end of 2022 was 39 million. This has led to mass testing to diagnose new cases, and the conduction of prognostic tests for monitoring HIV progression. This is being done to meet the targets of the 95%: 95%: 95% UN AIDS goal which is to be achieved by 2025.

The epidemiology of Lassa fever in Ghana: a study on the 2023 Lassa fever outbreak in Ghana.

Background: Viral disease outbreak remains a key public health concern given its impact on life and livelihood. Historical data suggests Lassa fever is endemic in several West African countries with sporadic cases occurring elsewhere in the region. In February 2023, Ghana recorded its second outbreak of Lassa fever following that of 2011.

Malaria among febrile patients suspected of Yellow fever during an outbreak in Ghana.

Introduction: Between October 2021 and February 2022, there was an outbreak of Yellow fever that spread within several districts in the northern part of Ghana. Febrile illnesses such as Yellow fever are often misdiagnosed as malaria and vice versa, which delays appropriate management and treatment. Hence, the true burden of Yellow fever and malaria are mostly underestimated.

Molecular detection of dengue virus from febrile patients in Ghana.

Background: Viral hemorrhagic fevers (VHFs) belong to a group of viral infectious diseases that interfere with the blood's clotting mechanism. VHF has a wide host range, including bats, rodents, or arthropods such as mosquitoes and ticks. Most VHFs emerge suddenly as outbreaks, making it difficult to predict occurrence.

Entomological risk assessment for transmission of arboviral diseases by Aedes mosquitoes in a domestic and forest site in Accra, Ghana.

Dengue, Zika and chikungunya are Aedes-borne viral diseases that have become great global health concerns in the past years. Several countries in Africa have reported outbreaks of these diseases and despite Ghana sharing borders with some of these countries, such outbreaks are yet to be detected. Viral RNA and antibodies against dengue serotype-2 have recently been reported among individuals in some localities in the regional capital of Ghana.

Molecular Characterization of Circulating Yellow Fever Viruses from Outbreak in Ghana, 2021-2022.

Yellow fever virus, transmitted by infected Aedes spp. mosquitoes, causes an acute viral hemorrhagic disease. During October 2021-February 2022, a yellow fever outbreak in some communities in Ghana resulted in 70 confirmed cases with 35 deaths (case-fatality rate 50%).

World Hepatitis day 2021 -screening and vaccination against Hepatitis B virus in Accra, Ghana.

Background: In Ghana, Hepatitis B virus (HBV) infection remains a major public health threat as in many parts of the world. Even with an effective vaccine, there are shortfalls with low vaccine coverage among adults. To create awareness and encourage vaccination, community engagement and public-private partnerships are needed in endemic settings to help fund campaigns and offer screening and vaccinations at no cost to under privileged people.

Molecular characterization of haemagglutinin genes of influenza B viruses circulating in Ghana during 2016 and 2017.

Recent reports of haemagglutinin antigen (HA) mismatch between vaccine composition strains and circulating strains, have led to renewed interest in influenza B viruses. Additionally, there are concerns about resistance to neuraminidase inhibitors in new influenza B isolates. To assess the potential impact in Ghana, we characterized the lineages of influenza B viruses that circulated in Ghana between 2016 and 2017 from different regions of the country: Southern, Northern and Central Ghana.

Hepatitis C virus (HCV) infection among patients with sickle cell disease at the Korle-Bu teaching hospital.

Background: Hepatitis C virus (HCV) infection is a blood borne infection that remains potentially transmissible through blood transfusions. Sickle cell disease (SCD) is a common inheritable haemoglobinopathy in Ghana that requires multiple blood transfusions as part of its management. The SCD patient is therefore at a high risk of HCV infection; however, data on the occurrence of HCV in SCD patients has not been documented in Ghana.

Diagnosis of tuberculosis among COVID-19 suspected cases in Ghana.

Background: Tuberculosis (TB) and COVID-19 pandemics are both diseases of public health threat globally. Both diseases are caused by pathogens that infect mainly the respiratory system, and are involved in airborne transmission; they also share some clinical signs and symptoms. We, therefore, took advantage of collected sputum samples at the early stage of COVID-19 outbreak in Ghana to conduct differential diagnoses of long-standing endemic respiratory illness, particularly tuberculosis.

Arbovirus circulation among febrile patients at the greater Accra Regional Hospital, Ghana.

Objective: Arboviruses, Dengue and Chikungunya have become major international public health concerns due to their epidemics and introduction in new areas. In Ghana, little is known is about Dengue and Chikungunya viruses though the country has been listed as part of the 34 countries in which the viruses are endemic. This has been attributed partly to the lack of diagnostic tools for these viruses in several health facilities and institutions across the country.

Serological evidence of Zika virus infection in febrile patients at Greater Accra Regional Hospital, Accra Ghana.

Objective: Increase in the evidence of global occurrence of Zika viral infection suggests that in Africa the circulation of the virus which causes 80% of asymptomatic infection could be undetected and/or overlooked. We sought to serologically detect Zika virus infection in febrile patients at Greater Accra Regional Hospital, Ghana.

Results: Of the 160 patient serum samples analyzed, 33 were found to have antibodies against Zika virus infection.

Molecular detection of dengue virus in patients suspected of Ebola virus disease in Ghana.

Dengue fever is known to be one of the most common arthropod-borne viral infectious diseases of public health importance. The disease is now endemic in more than 100 countries in Africa, the Americas, the Eastern Mediterranean, Southeast Asia and the Western Pacific with an estimated two fifths of the world's population being at risk. The notable endemic viral hemorrhagic fevers (VHFs) found in West Africa, including yellow fever, Lassa fever, Rift Valley fever, dengue fever and until recently Ebola have been responsible for most outbreaks with fatal consequences.

Molecular investigations of viral meningitis among HIV-infected adults in Accra, Ghana.

Objective: Meningitis is one of the leading causes of death among patients living with the human immunodeficiency virus (HIV) in sub-Saharan Africa. Based on clinical presentations alone, the different types of meningitis may not be distinguished from each other, consequently accurate laboratory diagnosis is extremely essential. Viruses such as Enteroviruses (EV), Mumps virus (MuV) and Herpes Simplex Virus-1 (HSV-1) are implicated in cases of meningitis.

Biosecurity measures to reduce influenza infections in military barracks in Ghana.

Background: Military barracks in Ghana have backyard poultry populations but the methods used here involve low biosecurity measures and high risk zoonosis such as avian influenza A viruses or Newcastle disease. We assessed biosecurity measures intended to minimize the risk of influenza virus infection among troops and poultry keepers in military barracks.

Findings: We educated troops and used a questionnaire to collect information on animal populations and handling practices from 168 individuals within 203 households in military barracks.

Hospital-based surveillance for viral hemorrhagic fevers and hepatitides in Ghana.

Background: Viral hemorrhagic fevers (VHF) are acute diseases associated with bleeding, organ failure, and shock. VHF may hardly be distinguished clinically from other diseases in the African hospital, including viral hepatitis. This study was conducted to determine if VHF and viral hepatitis contribute to hospital morbidity in the Central and Northern parts of Ghana.

Fatal hepatitis E viral infection in pregnant women in Ghana: a case series.

Background: Viral infections during pregnancy can pose serious threats to mother and fetus from the time of conception to the time of delivery. These lead to congenital defects, spontaneous abortion and even death. The definitive diagnosis and management of pregnancy-related viral infections may be challenging especially in less resourced countries.
