Introduction: Sub-Saharan Africa remains one of the regions most affected by HIV infection with severe lethality.Most deaths of patients living with HIV are caused by opportunistic infections. Objective: to determine the prevalence of opportunistic infections among patients living with HIV in hospital serving infectious diseases of UHC YO of Ouagadougou. Patients and Methods:This is a cross-sectional descriptive study covering a 14-month period from 1 January 2017 to 28 February 2018. Included were all HIV-positive patients, hospitalized at the service of Infectious Diseases, in which an opportunistic infection was diagnosed on the basis of clinical and/or para-clinical arguments. Results: During the study period a total of 55 patients living with HIV were hospitalized in the infectious disease unit,35 of whom had at least one opportunistic infection or 63.6% of the patients.The average age of patients was 37 years with extremes of 18 and 66 years.Twenty-two patients were female versus 13 male, a sex ratio = 0.59. HIV1 was involved in 97% of patients.The mean TCD4 lymphocyte rate was 156 cell/mm3 with extremes of 7 and 718 cell/mm3.Tuberculosis and digestive mycosis were the most frequently diagnosed opportunistic infections. Opportunistic infection was the circumstance for HIV testing in two patients.She revealed immune restoration syndrome in two other patients.Nineteen patients were already on antiretroviral treatment upon admission to the service.Half of the patients on treatment were in therapeutic failure.The evolution was marked by 26.5% lethality. Conclusion:The frequency of opportunistic infections is high in patients living with HIV.Their prevention requires early detection of HIV infection and antiretroviral treatment.

Purpose: The study aimed at presenting a comparative appraisal of the trends of the two most prevalent infectious diseases bedeviling the region: human immunodeficiency virus (HIV) and tuberculosis (TB). Subject & Methods: Data on fourteen ECOWAS member countries and also fourteen member countries of the SADC bloc. This represents about 93.3% and 87.5% membership of the ECOWAS and SADC blocs respectively. Although the choice of sample size is determined largely by the availability of data, the choices were carefully made to maximize available observation. The data were sourced from World Development Indicators online database published by the World Bank. We use two measures of infectious diseases: the prevalence rate of human immunodeficiency virus and the incidence of tuberculosis. Results: The HIV prevalence rates and incidence of TB were uneven in the two selected trade blocs. The magnitude and the severity of the diseases varied. The burden of both diseases was higher for SADC and lesser for ECOWAS. The average prevalence rate of HIV in the SADC bloc over the study period was 600% of the prevalence rate in ECOWAS (SADC = 12.5%, ECOWAS = 2.1%). Likewise, in the same period, the average TB incidence per 100,000 people was 578.8 and 181.7 respectively in the SADC and ECOWAS blocs. Conclusions: The study finds that the magnitude and severity of the diseases vary widely between the Economic Community of West Africa States (ECOWAS) and the Southern Africa Development Community (SADC) trade blocs. And, while concerted efforts at curbing the diseases have yielded results, there is still much to be done in both blocs.

We study the effects of development and climate change on infectious diseases in Sub-Saharan Africa. Infant mortality and infectious disease are closely related, but there are better data for the former. In an international cross-section, per capita income, literacy, and absolute poverty significantly affect infant mortality. We use scenarios of these three determinants and of climate change to project the future incidence of malaria, assuming it to change proportionally to infant mortality. Malaria deaths will first increase, because of population growth and climate change, but then fall, because of development. This pattern is robust to the choice of scenario, parameters, and starting conditions; and it holds for diarrhoea, schistosomiasis, and dengue fever as well. However, the timing and level of the mortality peak is very sensitive to assumptions. Climate change is important in the medium term, but dominated in the long term by development. As climate can only be changed with a substantial delay, development is the preferred strategy to reduce infectious diseases even if they are exacerbated by climate change. Development can, in particular, support the needed strengthening of disease control programs in the short run and thereby increase the capacity to cope with projected increases in infectious diseases over the medium to long term. This conclusion must, however, be viewed with caution, because development, even of the sort envisioned in the underlying socio-economic scenarios, is by no means certain.

Abstract The trajectory and impact of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic in sub-Saharan Africa are unclear, but they are seemingly varied between different countries, with most reporting low numbers. We use the situation in Zimbabwe to build an argument that the epidemic is likely to be attenuated in some countries with similar socioeconomic and cultural structures. However, even an attenuated epidemic may overwhelm weak health systems, emphasizing the importance of prevention. These prevention strategies should be tailored to the unique social and cultural networks of individual countries, which may facilitate the spread of SARS-CoV-2. It is also equally important to maintain services for the major infectious diseases in the region, such as tuberculosis and malaria. A breakdown of treatment and prevention services for these conditions may even overshadow the projected morbidity and mortality from coronavirus disease 2019 (COVID-19).

Our world is rapidly urbanizing. According to the United Nations, between 1990 and 2015, the percent of the world’s population living in urban areas grew from 43% to 54%. Estimates suggest that this trend will continue and that over 68% of the world’s population will call cities home by 2050, with the majority of urbanization occurring in African countries. This urbanization is already having a profound effect on global health and could significantly impact the epidemiology of infectious diseases. A better understanding of infectious disease risk factors specific to urban settings is needed to plan for and mitigate against future urban outbreaks. We conducted a systematic literature review of the Web of Science and PubMed databases to assess the risk factors for infectious diseases in the urban environments of sub-Saharan Africa. A search combining keywords associated with cities, migration, African countries, infectious disease, and risk were used to identify relevant studies. Original research and meta-analyses published between 2004 and 2019 investigating geographical and behavioral risk factors, changing disease distributions, or control programs were included in the study. The search yielded 3610 papers, and 106 met the criteria for inclusion in the analysis. Papers were categorized according to risk factors, geographic area, and study type. The papers covered 31 countries in sub-Saharan Africa with East Africa being the most represented sub-region. Malaria and HIV were the most frequent disease focuses of the studies. The results of this work can inform public health policy as it relates to capacity building and health systems strengthening in rapidly urbanizing areas, as well as highlight knowledge gaps that warrant additional research.
