South Africa became one of the first African countries to receive COVID-19 vaccine. As rest prepares vaccines, most in have set up national-level coordination committees for developing national vaccination deployment plans. While main focus these has been on setting strategies that facilitate swift distribution vaccines once they are available, role effective public health awareness should not be ignored. Countries must devise how best enhance understanding and curb misinformation about...
The emergence and fast global spread of COVID-19 has presented one the greatest public health challenges in modern times with no proven cure or vaccine. Africa is still early this epidemic, therefore extent disease severity not yet clear. We used a mathematical model to fit observed cases South estimate basic reproductive number critical vaccination coverage control for different hypothetical vaccine efficacy scenarios. also estimated percentage reduction effective contacts due social...
The COVID-19 pandemic has wrought a profound impact on mental health in Sub- Saharan Africa, exacerbating existing disparities and rendering individuals undergoing treatment particularly susceptible. This comprehensive critical review delves into the scope, nature, extent of services while concurrently elucidating pivotal lessons exemplary practices learnt from periods lockdown.
In 2016, an estimated 1.5 million females aged 15-24 years were living with human immunodeficiency virus (HIV) infection in Eastern and Southern Africa, where the prevalence of HIV among adolescent girls young women (3.4%) is more than double that for males same age range (1.6%) (1). Progress was assessed toward Joint United Nations Programme on HIV/AIDS (UNAIDS) 2020 targets sub-Saharan Africa (90% those aware their status, 90% HIV-infected persons status antiretroviral treatment [ART],...
The population-based HIV impact assessment (population-based assessments) surveys are among the first to estimate national adult incidence, subnational prevalence of viral load suppression, and pediatric prevalence. We summarize survey methods implemented in Zimbabwe, Malawi, Zambia, as well response rates quality metrics.
Objective The US recently suffered the fourth and most severe wave of COVID-19 pandemic. This was driven by SARS-CoV-2 Omicron, a highly transmissible variant that infected even vaccinated people. Vaccination coverage disparities have played an important role in shaping epidemic dynamics. Analyzing epidemiological impact this uneven vaccination is essential to understand local differences spread outcomes Omicron wave. Therefore, objective study quantify disparity dynamics pandemic during...
Abstract Introduction The burden of HIV in sub‐Saharan Africa (SSA) remains unacceptably high, and disproportionately affects girls women. While the introduction oral pre‐exposure prophylaxis (PrEP) 2012 revolutionized prevention, its effectiveness is dependent on user adherence implementation SSA has faced numerous challenges. Patient‐level, interpersonal structural barriers, including, for example, daily pill burden, side effects, lack partner support, testing disclosure, costs have been...
Background This study uses surveillance, survey and program data to estimate past trends current levels of HIV in Botswana the effects treatment prevention programs. Methods/Principal Findings Data from sentinel surveillance at antenatal clinics a national population were used trend adult prevalence 1980 2007. Using we estimated number new infections, transmission mothers children, need for antiretroviral therapy (ART) child deaths. Prevalence has declined slowly urban areas since 2000...
The global target for 2020 is that ≥90% of people living with HIV (PLHIV) receiving antiretroviral therapy (ART) will achieve viral load suppression (VLS). We examined VLS and its determinants among adults ART at least four months.
The global COVID-19 pandemic has resulted in an upsurge antimicrobial use. increase use is multifactorial, and particularly related to the empirical treatment of SARS-CoV-2 suspected coinfections with antimicrobials limited quality diagnostics differentiate viral bacterial pneumonia. lack clear clinical guidelines across a wide range settings, inadequacy public health sectors many countries, have contributed this pattern. increased potential incidences resistance, especially low-resource...
Sub-Saharan Africa carries the highest burden of HIV-1 and AIDS. About 39% all new infections in world 2020 were this region. Oral PrEP was found to be very effective reducing risk transmission. However, its effectiveness is highly dependent on users adhering drugs. The availability long-acting injectable that eliminates need for a daily pill may increase uptake adherence people who struggle adhere oral PrEP. USA's FDA approved cabotegravir (CAB-LA) December 2021. In review, we discussed...
The impact of the COVID-19 vaccination campaign in US has been hampered by a substantial geographical heterogeneity coverage. Several studies have proposed hesitancy as key driver uptake disparities. However, other important structural determinants such local disparities healthcare capacity is virtually unknown.In this cross-sectional study, we conducted causal inference and geospatial analyses to assess on coverage disparity US. We evaluated relationship between system 2417 counties their...
Since the first monkeypox (MPX) case was reported in humans 1970, there have been several outbreaks of disease. MPX is endemic central and western Africa. virus infection confirmed using conventional polymerase chain reaction, which detects viral DNA samples from rash. Of concern that current outbreak has affected five regions world. Although confirmatory tests are available worldwide, concerns about Africa's capacity to diagnose contain The challenges faced by Africa include a lack adequate...
Abstract Introduction Achieving optimal HIV outcomes, as measured by global 90‐90‐90 targets, that is awareness of HIV‐positive status, receipt antiretroviral (ARV) therapy among aware and viral load (VL) suppression those on ARVs, respectively, critical. However, few data from sub‐Saharan Africa (SSA) are available older people (50+) living with (OPLWH). We examined progress age, 15–49 (as a comparison) 50+ years, further analyses (55–59, 60–64, 65+ vs. 50–54), in 13 countries (Cameroon,...
