Adult Pneumococcal Vaccination in Ghana: Current Status and Future Recommendations - Expert Opinion.

Vaccination programs have proven successful in the prevention and control of infectious diseases among children on a global scale, but the majority of adult populations remain unvaccinated. immunocompromised adults as well as older adults aged low-income countries as Streptococcus pneumoniae infections are associated with substantial morbidity and mortality among 65 years and above. Despite the introduction of pneumococcal conjugate vaccines (PCVs), the burden of vaccine-type serotypes remains high in there are no clear policies for adult vaccination. As per the Global Burden of Disease 2019 report, about 120,000 individuals aged 70 years and older died as a result of LRTIs) in sub-Saharan Africa. A medical advisory board meeting was conducted in April 2022 to discuss the burden of pneumococcal diseases in adults, the current status of policies and practices of adult vaccination, unmet needs, and challenges in Ghana. This expert opinion paper outlines the pneumococcal epidemiology and burden of disease in Ghana, as well as the rationale for adult pneumococcal vaccination. It also highlights the potential barriers to adult vaccination and offers recommendations to overcome these obstacles and enhance vaccine acceptance in Ghana.

Les programmes de vaccination ont prouvé leur succès dans la prévention et le contrôle des maladies infectieuses chez les enfants à l'échelle mondiale, mais la majorité des populations adultes restent non vaccinées. Les infections à Streptococcus pneumoniae sont associées à une morbidité et une mortalité substantielles chez les adultes immunodéprimés ainsi que chez les personnes âgées de 65 ans et plus. Malgré l'introduction des vaccins conjugués contre le pneumocoque (VCP), la charge des sérotypes vaccinaux reste élevée dans les pays à faible revenu car il n'existe pas de politiques claires en matière de vaccination des adultes. Selon le rapport sur la charge mondiale de morbidité de 2019, environ 120 000 personnes âgées de 70 ans et plus sont décédées des suites d'infections des voies respiratoires inférieures (IVRI) en Afrique subsaharienne. Une réunion du conseil consultatif médical a eu lieu en avril 2022 pour discuter du fardeau des maladies pneumococciques chez les adultes, de l'état actuel des politiques et pratiques de vaccination des adultes, des besoins non satisfaits et des défis au Ghana. Cet article d'opinion d'experts présente l'épidémiologie pneumococcique et le fardeau de la maladie au Ghana, ainsi que les arguments en faveur de la vaccination pneumococcique des adultes. Il met également en lumière les obstacles potentiels à la vaccination des adultes et propose des recommandations pour surmonter ces obstacles et améliorer l'acceptation des vaccins au Ghana.

COVID-19 in patients presenting with malaria-like symptoms at a primary healthcare facility in Accra, Ghana.

BACKGROUND: Malaria is a common and severe public health problem in Ghana and largely responsible for febrile symptoms presented at health facilities in the country. Other infectious diseases, including COVID-19, may mimic malaria due to their shared non-specific symptoms such as fever and headache thus leading to misdiagnosis. This study therefore investigated COVID-19 among patients presenting with malaria-like symptoms at Korle-Bu Polyclinic, Accra, Ghana. METHODS: This study enrolled 300 patients presenting with malaria-like symptoms aged ≥18yrs. After consent was obtained from study patients, two to three millilitres of whole blood, nasopharyngeal and oropharyngeal swab samples, were collected for screening of Plasmodium falciparum using malaria rapid diagnostic test, microscopy and nested PCR, and SARS-CoV-2 using SARS-CoV-2 antigen test and Real-time PCR, respectively. The plasma and whole blood were also used for COVID-19 antibody testing and full blood counts using hematological analyser. SARS-CoV-2 whole genome sequencing was performed using MinIon sequencing. RESULTS: The prevalence of malaria by microscopy, RDT and nested PCR were 2.3%, 2.3% and 2.7% respectively. The detection of SARS-CoV-2 by COVID-19 Rapid Antigen Test and Real-time PCR were 8.7% and 20% respectively. The Delta variant was reported in 23 of 25 SARS-CoV-2 positives with CT values below 30. Headache was the most common symptom presented by study participants (95%). Comorbidities reported were hypertension, asthma and diabetes. One hundred and thirteen (37.8%) of the study participants had prior exposure to SARS CoV-2 and (34/51) 66.7% of Astrazeneca vaccinated patients had no IgG antibody. CONCLUSION: It may be difficult to use clinical characteristics to distinguish between patients with COVID-19 having malaria-like symptoms. Detection of IgM using RDTs may be useful in predicting CT values for SARS-CoV-2 real-time PCR and therefore transmission.

Incidental finding of COVID-19 infection amongst staff at a primary care facility in Ghana.

The COVID-19 pandemic has affected nearly every country worldwide and all African countries. The issue of healthcare workers (HCWs) contracting the disease is a growing concern in Ghana, because of the risk of spreading infections amongst themselves and to vulnerable patients in their care. This article illustrates how 14 staff at the Korle Bu Polyclinic/Family Medicine Department were incidentally found to be Covid-19 positive with most of them being asymptomatic. This observation led to a modification of the personal protective equipment (PPE) used by clinical staff when attending to patients. Furthermore, this finding suggests that a different criteria or guideline may be needed for testing of HCWs during a pandemic where a significant proportion of infected people are asymptomatic. We conclude that in the primary care setting HCWs must be ready to see all the following cases safely: routine patients, asymptomatic COVID-19 patients and suspected COVID-19 patients.
