Public health data analysis

Poverty, sex work and infectious disease in Nigeria

How deprivation and unequal access to prevention services shape the burden of HIV and other infections. The first half uses published surveillance figures. The second half is a transparent what-if model you can adjust.

How to read this. These are associations, not proof that one thing causes another. Sex work does not by itself cause disease: risk is driven by how often condoms are used, access to testing, treatment and PrEP, violence, stigma, criminalisation and poverty that pushes people to accept unsafe terms. Figures come from different surveys and years, so comparisons are indicative.

Part 1 · What the published data shows

HIV prevalence by population (%)

Adults from the 2018 national household survey; key populations from the 2020 biological and behavioural survey.

Multidimensional poverty (% of people poor)

National MPI 2022: health, education, living standards, work and security.

Poverty pathway

  • High deprivation in sanitation, time to healthcare, food insecurity and housing (NBS 2022)
  • Poor sanitation and crowding raise the risk of water-borne and respiratory infections such as cholera and tuberculosis
  • Late care-seeking turns treatable infections into serious ones

Sex-work risk pathway

  • Surveillance finds many partners and low consistent condom use, especially with regular partners
  • HIV testing coverage targets were missed among key populations in 2020
  • Stigma, violence and criminalisation keep people away from clinics

Where they overlap

  • Economic need can lead to accepting condomless sex for higher pay
  • Untreated STIs raise HIV risk, and HIV raises vulnerability to TB
  • Cash support, free testing, PrEP and treatment attack both pathways at once

Part 2 · Intervention scenario model

A simple closed-cohort model of 1,000 female sex workers followed for 5 years, starting at the 2020 survey HIV prevalence of 15.5%. Move the sliders to see how prevention coverage changes new infections. This is an illustration of the logic, not a forecast.

Model assumptions: starting prevalence 15.5% (UNAIDS, 2020); baseline new infections of 4 per 100 person-years among HIV-negative people is an assumption chosen for illustration; no turnover, deaths or migration; effects of the four levers are multiplied. Change the code to test other values.

What I can do for you

Services

From a first website to a dashboard that answers your business questions.

Business websites

Fast, mobile-first sites for shops, workshops, churches and agencies, with contact forms and WhatsApp links that bring in enquiries.

Web apps

Sign-in, member areas, booking flows and admin pages, using Node.js, PHP or Firebase depending on what the project needs.

Dashboards & analytics

Clean your spreadsheets, find the patterns and present them as interactive charts your team can actually read.

Redesign & UI/UX

Give an old site a modern layout, better speed and clearer calls to action without losing the content you already have.

Before you ask

Frequently asked questions

What do you build?
Business websites, web apps with sign-in and booking, e-commerce storefronts, and data dashboards. If it runs in a browser, I can probably build it.
How long does a website take?
A focused business site usually takes one to two weeks once I have your content. Web apps with accounts or databases take longer, and I give you a timeline after our first call.
How much does it cost?
It depends on scope: pages, features and how much content is ready. Pick a budget range in the project form below and I will reply with a clear quote and what it includes.
Will it work on phones?
Yes. Everything I build is mobile-first and tested on small screens, because most of your visitors will be on a phone.
Do you help with hosting and domains?
Yes. I deploy to fast hosts such as Netlify or GitHub Pages, connect your domain, and show you how to make simple updates yourself.
Can you analyse my business data?
Yes. Send me a spreadsheet or export, and I will clean it, find the trends and build a dashboard like the one above, or a short written report.
How do we get started?
Fill in the project form or message me on WhatsApp. Tell me what you need and when, and I will reply with next steps.
