The recent introduction of sachet water to consumers was provide safe, hygienic and affordable instant drinking the public. Although this is a laudable idea current trends seem suggest that could be route transmission enteric pathogens.To assess safety water.Twenty seven different brands 500ml samples randomly selected purchased from various vendors in Accra were subjected microscopic examinations determine presence parasitic protozoa. study carried out between January May 2005.Seventy-seven...
ABSTRACT Genotyping of human rotaviruses was performed on 312 rotavirus-positive samples collected from 2,205 young children with diarrhea in the Upper East District Ghana, a rural community. Of 271 (86.9%) rotavirus strains that could be VP7 (G) or VP4 (P) characterized, 73 (26.9%) were G9 specificity. The predominant genotype G9P[8], which constituted 79.5% all detected, followed by G9P[6] (12.3%), G9P[10] (2.7%), and G9P[4] (1.3%). mixed P types 2.7% found study. All G9P[8] had long RNA...
Human Papillomavirus (HPV) infections have been shown to be a necessary risk factor for the development of cervical cancer. However, HPV genotype distribution varies geographically, both in type and relative prevalence. In order ensure successful introduction available vaccines, there is need identify pre-vaccination prevalence Ghana extent single multiple-infections.
Abstract Background Progress toward malaria elimination is increasing as many countries near zero indigenous cases. In settings nearing elimination, interventions will be most effective at interrupting transmission when targeted the residual foci of transmission. These may missed due to asymptomatic infections. To solve this problem, World Health Organization recommends reactive case detection (RACD). This study was conducted identify individuals with malaria, their predisposing risk factors...
Background Cervical cancer ranks as the fourth most common among women, with 662,301 new cases and 348,874 deaths reported in 2022. The majority of disease burden occurs low- middle-income countries. In Ghana, there were 3072 1815 While human papillomavirus (HPV) infection, a key cause for cervical cancer, resolves individuals, it can progress to some. This has led research into other factors that may, conjunction HPV, increase risk progression. Improving knowledge factors, screening will be...
Summary We measured the type‐specific incidence of paediatric rotavirus diarrhoea in an area northern Ghana. Over 1 year, 1717 episodes were identified, which 677 (39%) positive for rotavirus. Risk factors infection included old age, wasting, high Vesikari score and episode occurring dry season. Rotavirus‐positive tended to be more acute, causing vomiting greater dehydration, likely require hospitalization. The was 0.089 per person‐year all diarrhoea, 0.035 diarrhoea. observed decreased...
This study was designed to investigate whether household cockroaches harbor cephalosporin-resistant enterobacteria that share resistance determinants with human inhabitants. From February through July 2016, whole cockroach homogenates and fecal samples from 100 households were cultured for (CRe). The CRe examined plasmid-mediated AmpC, ESBL, carbapenemase genes; antibiotic susceptibility patterns; conjugative transfer of mechanisms. Clonal associations between determined by multi-locus...
Determining the high-risk human papillomavirus (HR-HPV) genotypes burden in women with and without cervical cancer afford a direct comparison of their relative distributions. This quest is fundamental to implementing future population-based prevention strategy Ghana. We estimated risk by HPV genotypes, vaccine-preventable proportion diagnosed
Sixty-seven rotavirus-positive fecal samples, collected between January and April 1999, from children with diarrhea in the Upper East Region of Ghana were examined for rotavirus VP7 VP4 types. Sufficient viral RNA could be obtained 46 (68.7%) samples all isolates had short electrophoretic pattern typed as subgroup I rotaviruses by ELISA. Three strains G8 specificity identified first time Ghana. G P typing PCR two distinct strains, P[6]G2 (50%) P[6]G8 (4.3%). Eighty-two percent (n = 38)...
Cyperus esculentus L, is a minor but important crop in Ghana. They are noted mostly by their aphrodisiac properties among others. The nuts often eaten raw as an unprocessed snack due to its rich flavour and texture. Though raw, the sometimes handled unhygienically, posing public health threat. This study therefore aimed at determining level distribution of parasitic bacterial contaminants associated with it sold. Four types intestinal parasites were identified, most prevalent was...
Introduction: Helicobacter pylori is a gram-negative urease-producing bacteriumcausally linked with gastritis, peptic ulcer disease and gastric adenocarcinoma. Infection more frequent acquired at an earlier age in developing countries compared to European populations.The incidence of infection dyspeptic Ghanaian patients was 75.4 %. However, epidemiological factors associated vary across populations.
As part of malaria characterization study in the South-Tongu district Ghana, current was conducted to explore relationships between malaria, schistosomiasis, soil transmitted helminths and malnutrition riparian community settings that had hitherto encountered episodes mass deworming exercises. School-age children were enrolled a cross-sectional from April through July 2012. Stool urine samples examined respectively for Schistosoma haematobium. Blood analyzed parasites haemoglobin (Hb)...
Cervical cancer is the most common gynaecologic in Ghana where it also second cause of all female cancers. A number vaccines are available to provide both individual and population-level protection against persistent infection with high-risk human papillomaviruses (HR-HPV) reduce burden cervical cancer. Data on epidemiology vaccine-preventable scant.
Vaccination is the most effective preventive strategy against rotavirus disease. Regional differences in prevalent genotypes may affect vaccine efficacy. Pre-vaccine surveillance for burden of disease, genotypes, and association between disease intussusceptions helps monitoring impact vaccination.A prospective study was conducted from January 2008 to December 2009 children younger than five years hospitalized longer 24 hours with acute gastroenteritis. Data on confirmed cases intussusception...
Abstract Ghana does not have a universal population-based cervical cancer screening program and there is very limited information about the distribution of epithelial cell lesions. This study provides evidence that moderately high prevalence precancerous lesions exists among unscreened women in Kumasi. The abnormalities cross-section attending for first time suburb from 2011 to 2014 was studied. Cervical smears were prepared examined independently by 2 cytotechnologists confirmed...
An epidemiological study of rotavirus infection was conducted on specimens collected from patients with gastroenteritis and domiciled in the rural Upper Eastern Region Ghana during 1998. Fifty isolates, randomly selected 165 human group A rotavirus-positive samples, were G P characterized by a reverse transcription (RT)-PCR assay using seminested multiplex method. Rotaviruses G3 genotype found to be predominant strain (78%), followed G2 (14%) G1 (2%). Mixed infections, as shown combinations...
Helicobacter pylori infection is prevalent in Ghana.

The major burden of cervical cancer occurs in low- and middle-income countries. In Ghana, it is the second most common among women. Infection with high-risk human papilloma virus (HPV) has been established as cause cancer. As such, important to identify risk factors that may affect progression from HPV infection
The incidence of calicivirus infection in Ghana and many other African countries is not known. Thirteen (15.9%) the 82 diarrhoeic stool samples tested for caliciviruses were positive noroviruses (NoVs). NoVs present all age groups detected only during diarrhoea peak that coincided with rotavirus season. Ten (76.9%) NoV genogroup II (GII) remaining three (23.1%) I (GI) NoVs. predominant GII was GII-4 (60%, 6/10). Three determined to be recombinants GII-8/GII-14 as deduced from sequencing...
Human rotavirus infection was studied over a 13-month period (January 2004 to January 2005) in children <5 years of age admitted with severe diarrhea at the Korle-Bu Teaching Hospital Accra, Ghana. During this period, 206 hospitalizations for were recorded, 34.0% (70/206) being positive infection. Infection occurred throughout year, peak occurring during month March. Hospitalization associated rotaviruses most common 6-8 group. The case fatality rate 2.9% (2/70) and <12 months age. Four VP7...
