Children symptoms general hospitals health centers Nigeria were recruited for this study. Vaccination history, clinical details, 5 mL...
An understanding of the COVID-19 spread is growing around world, yet little known Africa. This paper explores time-space geographies infection focusing on Africa and Nigeria especially. We appraise global-to-local situation confirmed cases, deaths recoveries as well measures engaged in response to pandemic. Findings reveal that South accounts for 40% total cases Africa, followed by Egypt (18%), (6.8%), Ghana (4.6%) Algeria (3.6). Our study shows a significant relationship between population...
Hepatitis B virus (HBV) infection is a major health challenge in sub-Saharan African countries. Chronic HBV risk factor for severe disease progression. Perinatal and sexual transmissions of are the main routes endemic countries like Nigeria. However, there paucity data as regards contributory route transmission to chronic this region. Also, Nigeria, not everyone at high has been identified. Therefore our study investigated prevalence among sexually active individuals Nigeria.Blood samples...
Introduction HIV causes defects in memory B cells children, but the mechanisms of those have not been fully elucidated. One possible mechanism is lack T-cell help to during immune reactions. However, few studies assessed effect on follicular helper T (TFH cells) children. Methods In this study, follicular-homing CD4 and were HIV-infected children compared with from community. CXCR5 CD45RO used as markers cells, respectively. Memory TFH identified CD3+CD8-CD4+CXCR5+CD45RO+PD1+. Central based...
Group A rotavirus (RVA) genotype G12 has spread globally and become one of the most prevalent genotypes in Africa. To understand drivers for its genetic diversity rapid we investigated Bayesian phylogeography, viral evolution population demography Rotavirus We downloaded aligned VP7 gene sequences G12, from thirteen African countries (n = 96). Phylogenetic analysis, Evolutionary analysis Phylogeography was carried out, using MEGA Vs 6, BEAST, SPREAD3. revealed that all fell into lineage III...
Globally, influenza A virus (IAV) and respiratory syncytial (RSV) infection remain very high. There is also a high burden of IAV RSV co-infection in developing countries. To develop universally protective vaccines against these infections, it imperative that viral genes immune correlates pathology are elucidated. As such, we profiled expressions, histopathology immunological responses BALB/c mice infected with and/or this study.RSV A2 A/H3N2/Perth/16/09 (Pr/H3N2) were induced over seven-day...
Rubella is a vaccine-preventable, mild rash-inducing viral disease with complications that include spectrum of birth defects in the developing fetus, especially if infection acquired early months pregnancy. Consequently, primary objective global rubella control programs prevention congenital and associated defects. Despite availability safe effective vaccines, elimination virus many developed countries, substantial commitment to has not been demonstrated countries. This study appraises...
Hepatitis B virus (HBV) infection is a major public health problem for over two billion people infected globally. Occupationally exposed persons are at high risk of HBV and, apart from medical personnel, there dearth information concerning the prevalence and awareness among this population in Nigeria. This study was designed to determine levels hairdressers Ibadan, Hairdressers teachers (unmatched controls) four local government areas Ibadan were tested using ELISA technique. Dried blood...
Abstract Renal dysfunctions are major predictors of co‐morbidities and mortality in HIV‐infected individuals. Unconventional T cells have been shown to regulate kidney functions. However, there is dearth information on the effect HIV‐associated nephropathies γδ DN cells. It also not clear whether cell perturbations observed during early stages HIV infection occur before immune activation. In this study, we investigated relationship between creatinine urea number unconventional individuals at...
The association between household air pollution and lower respiratory tract infections (LRTI) among children under five years of age has been well documented; however, the extent to which microbiome within indoor environment contributes this is uncertain. home assessment (HAIM) study seeks assess abundance microbiota (IM) in homes under-five (U-5Cs) with without LRTI. HAIM a hospital- community-based involving 200 cases controls recruited from three children's hospitals Ibadan, Nigeria....
Abstract Purpose There were approximately 37.9 million persons infected with HIV in 2018 globally, resulting 770,000 deaths annually. Over 50% of this infection and occur sub‐Saharan Africa, countries like Nigeria being seriously affected. has one the highest rates new infections globally. To control Nigeria, there is a need to continually screen high‐risk groups for early subtypes using very sensitive methods. In study, HIV‐1 circulating among febrile blood donors determined. Performance...
Human T-cell lymphotropic virus types I/II (HTLV-I/II) is endemic in some parts of the world including Nigeria. Reported prevalence rates Nigeria have largely focused on blood donors. This study aims at determining HTLV infection among pregnant women Ilorin North-central Serum samples from 276 who were antenatal clinic attendees General and Civil Service Hospitals tested for presence HTLV-I/II antibodies using Enzyme Linked Immunosorbent Assay test kits Diagnostic Automation INC., USA.

Human T Cell Lymphotrophic virus (HTLV) is endemic in many regions of the world including Nigeria but not ubiquitous. It has been shown to be causally associated with cell leukaemia and other myelopathies. Heterosexual contact major route HTLV transmission. STDs patients, pregnant women sexually active individuals have at risk infection. However, there limited information on population mostly countries like Nigeria. Here we determined prevalence I II infection amongst three populations...
