NCDs, TB, Air Pollution & Climate-Related Diseases

NCDs, TB, Air Pollution & Climate-Related Diseases

Kenya faces rising health and economic risks from NCDs, TB, air pollution, and climate-linked diseases. While progress exists in TB control and digital health, gaps in funding, data, and infrastructure remain. Scalable solutions include tech-driven community health, clean energy adoption, climate-sensitive surveillance, and innovative financing.

Executive summary 

Noncommunicable diseases (NCDs), tuberculosis and pollution and climate-driven diseases together impose a rising, interconnected burden on Kenya’s health, economy and human capital, with air pollution alone shaving measurable months/years off life expectancy. Existing programmes (eCHIS, TB control, NCD screening, immunization) provide a base, but scaling tech-enabled, data-driven community solutions, climate-sensitive surveillance, clean-energy interventions and blended financing will be required to protect lives and stabilize food systems.

The problem — scale & how these conditions interact

A. Noncommunicable diseases (NCDs)

  • Global and local burden: NCDs (cardiovascular disease, diabetes, cancer, chronic respiratory disease) are the dominant cause of adult mortality worldwide and rising in Kenya; premature NCD mortality is concentrated in low- and middle-income countries.
  • Drivers: urbanization, sedentary lifestyles, unhealthy diets, tobacco and alcohol use, and exposure to ambient & household air pollution increase NCD incidence and severity. 

B. Tuberculosis (TB)

  • Persistent burden: Kenya remains among high-burden TB countries, recent WHO data show annual incidence in the hundreds of thousands and continued challenges with detection and co-infection (HIV/TB). TB control is undermined by poverty, overcrowding and weakened health systems. 

C. Air pollution & climate-driven disease

  • Life-years lost: Air pollution measurably shortens life expectancy, Kenya’s outdoor PM2.5 (particulate matter) levels are above WHO guidelines; globally, reducing PM2.5 to WHO levels adds years of life on average. In Kenya some regions would gain >1 year of life expectancy if WHO limits were met.
  • Climate as multiplier: Climate change increases heat-related mortality, spreads vector borne diseases (malaria, dengue), worsens food insecurity and degrades water/sanitation, all feeding into infectious disease risk, malnutrition and poorer NCD outcomes. 

D. Interaction effects

  • Co-morbid burden: Air pollution increases cardiovascular and respiratory disease risk — raising vulnerability to TB and worsening outcomes for diabetics and hypertensives. Climate shocks (droughts/floods) interrupt care, worsen nutrition and increase infectious disease outbreaks, compounding NCD and TB control challenges. 

What’s already in place (Kenya + global)

  • eCHIS (digital Community Health Information System) — Kenya has rolled out eCHIS to digitize CHW screening, referral and surveillance; it is already used for screening millions for hypertension and diabetes and can be expanded for air-quality and TB contact tracing data.
  • TB control programmes — National TB programmes supported by WHO/Global Fund use active case finding, HIV/TB integrated care and contact tracing, but detection gaps remain.
  • NCD screening & referral — Primary care and community programmes increasingly screen for hypertension and diabetes but need scale and continuity of care to achieve population impact. 

Global guidance & evidence base

  • WHO guidance on climate & health — WHO has spelled out climate threats to health and adaptation priorities (surveillance, essential services, heat action plans).
  • Air quality & health science — AQLI (Air Quality Life Index) and peer-reviewed literature quantify life expectancy losses from PM2.5 exposure and the health gains from meeting WHO guidelines. 

Gaps & constraints

  1. Data fragmentation & weak surveillance — incomplete case detection (TB) and inconsistent NCD registries; limited local air-quality monitoring networks.
  2. Finance shortfalls & misaligned funding — climate/air quality receives a small fraction of health funding relative to burden; NCDs and environmental health are underfunded.
  3. Capacity at community level — CHWs are essential but need tools, training, digital workflows, and referral linkages to sustain chronic care and rapid response to climate shocks.
  4. Energy & infrastructure constraints — many health facilities lack reliable power or cold-chain for diagnostics/vaccines; household reliance on polluting cookstoves persists. 

Recommended solutions (for Ministries, WHO, Govt, donors, local communities)

A. National policy & financing 

  1. Make climate-health an explicit health sector priority: Integrate climate risk assessment into all national health planning; create a Health-Climate Unit within MoH that coordinates with environment and disaster agencies.
  2. Scale blended finance for air quality & health resilience: Mobilize blended finance (government seed, Green Climate Fund grants, Multilateral Development Bank-MDB concessional loans, private impact capital) to fund clean energy for health facilities, community cookstove subsidy programs, and air-quality monitoring networks.
  3. Invest in national air-quality monitoring & public alerts: Expand fixed monitors in cities and regional hubs and deploy low-cost sensors linked to a public AQI dashboard and early warning for vulnerable populations.
  4. Mainstream NCD & TB continuity funding: Allocating and protecting specific budgets to guarantee uninterrupted access to medicines for chronic diseases, and to strengthen proactive TB detection efforts in communities and digital CHW systems (e.g., eCHIS scale-up).

B. Health system & service delivery 

  1. Scale community digital platforms (e.g., eCHIS + ICHH model): Expand CHW apps (screening, referral, adherence reminders) to capture NCD vitals, TB symptom screening/contact tracing, household air-quality readings, and nutrition metrics. Use these data to trigger referrals and micro-targeted interventions.
  2. Deploy community-level preventive packages: Package includes: NCD screening + lifestyle counselling, TB symptom screening + rapid referral, clean cookstove subsidy or PAYG clean-stove option, air-quality education and household monitors for the highest exposure homes.
  3. Strengthen TB detection with digital tools: Use CHW apps for symptom screening, digital chest X-ray triage (AI assist where available), SMS follow-up for test results, and home tracing for contacts. Ensure linkage to shorter TB regimens and social support.
  4. Heat early-warning & hospital preparedness: Develop heat-health action plans integrated with weather alerts and CHW reporting. Stockpile supplies for surge response after floods/droughts.

C. Community & technology (implementable by counties, NGOs, private sector)

  1. Integrated Community Health Hub (ICHH) — scale a CHW app + dashboard model: Use CHWs to screen for NCDs (BP, glucose), TB symptoms, nutrition and household PM2.5 via low-cost monitors. Automate referrals, medication reminders and teleconsultation links to clinics.
  2. Clean Energy & Respiratory Health Initiative (CERHI): Subsidized/financed smart clean cookstoves (PAYG or micro-loan) plus indoor air monitors. Partner with energy ministry for subsidies and carbon financing for scale.
  3. Digital Nutrition & Wellness Platform (DNWP) & lifestyle nudges: Mobile-first personalized nutrition/physical activity programme, gamified incentives, and tele-nutrition consults for chronic disease management (hypertension, diabetes). Link to local markets for healthy-food discounts.
  4. Digital Sexual Health & STI Management System (DSHS): Confidential chatbot-based STI risk assessment, anonymous partner notification, and QR referral for syndromic care — integrated with NASCOP (National AIDS and STI Control Programme) and youth outreach.

D. Environment & energy 

  1. Promote clean household energy at scale: National subsidy + PAYG delivery model for clean cookstoves and LPG where feasible; incentivize local manufacturing of low-cost clean stoves.
  2. Green health facilities: Prioritize solar + battery for primary health centers to power diagnostics and cold chain; include air filtration in high-risk hospitals. Finance via blended grants + concessional loans.

Governance, partnerships & financing (WHO, donors, counties)

  1. Cross-sectoral coordinating body — a national Health-Environment Steering Group (MoH, Environment, Energy, Treasury, WHO, civil society) to operationalize the plan and unlock blended finance.
  2. Use existing mechanisms — leverage Global Fund (TB/HIV), Gavi (immunization resilience), Green Climate Fund (health resilience grants), MDBs (PPPs, MDB guarantees) for blended pipelines.
  3. Data governance & open dashboards — publish anonymized community health & air-quality data to mobilize civil society, researchers and investors. 

Risks & mitigation

  • Risk: insufficient funding → Mitigation: staged pilots + blended finance to demonstrate results and crowd in private capital.
  • Risk: CHW burnout/data overload → Mitigation: simple UX (User Experience), real-time dashboards and task shifting; incentives for CHWs.
  • Risk: basis risk in sensor data / cookstove adoption → Mitigation: combine objective monitoring with behavior change campaigns and subsidy models.
