HIV/AIDS And Tuberculosis: Two Closely Related Diseases by Luz Calvo & Juan F. Gómez Celis

People living with HIV are around 20% times more likely to develop Tuberculosis than persons without this disease. Tuberculosis is the most common illness among people living with HIV, including those who are taking an antiretroviral treatment. Also it is the major cause of HIV-related deaths. Sub-Saharan Africa bears the brunt of the dual epidemic, accounting for approximately 86% of all deaths from HIV-associated TB in 2016. These numbers aim to create a collaboration between tuberculosis and HIV programmes, trying to reduce the burden of patients among people living with HIV and the burden of HIV among TB patients.

Through this micro visualisation, it is intended to explore certain aspects of the relationship of these diseases over time. We have used a line representation that plays with three different variables: slope, width and color.

For the lines with the blue scale: tuberculosis patients with known HIV status (%), Tested tuberculosis patients HIV positive (%) and HIV-positive tuberculosis patients on ART ( antiretroviral therapy) (%).
For the ocher scale, three other variables are analysed:
Incidence of tuberculosis (per 100.000 population), Tuberculosis treatment coverage (%), and number of deaths due to tuberculosis among HIV negative patients (per 100.000 population).
The trends of these two groups of variables are compared based on: a) A global view. b) Depending on the geographic area for the regions contemplated by World Health Organisation: Africa, America, Europe, South-east Asia, Eastern Mediterranean, and Western Pacific. c) and the third one, in which we also compare the trend based on their income level.
The visualisation uses three different graphic resources: Height or slope(y), width of the line and its color gradient, which are explained in the legend (see attached image).
