Preva AI is an AI-powered health intelligence platform built for Africa. It turns every NCD screening — blood pressure, blood sugar, kidney function, cardiovascular risk — into a decision that prevents stroke, diabetes and hospital emergencies.

Who does Preva AI serve?

Preva AI serves four audiences: Governments and Ministries of Health for policy planning, Insurers and HMOs for risk-adjusted underwriting, Corporate partners for ESG and wellness programs, and Citizens for personal health tracking.

Is Preva AI compliant with Ghana's Data Protection Act?

Yes. Preva AI is registered with Ghana's Data Protection Commission and fully compliant with the Data Protection Act (2012, Act 843). Data is stored on Ghanaian sovereign cloud infrastructure with AES-256 encryption.

How does Preva AI protect health data?

Preva AI uses end-to-end AES-256 encryption, TLS 1.3 in transit, de-identification by default, and consent-based data handling. All data remains on Ghanaian sovereign infrastructure.

What are NCDs and why do they matter in Africa?

Non-Communicable Diseases (NCDs) like stroke, diabetes, hypertension and kidney failure account for 71% of global deaths, with 82% occurring in low and middle-income countries. In many African nations, NCDs now kill more people than malaria, HIV and TB combined.

The Crisis

NCDs are the silent epidemic Africa didn't see coming.

Stroke, diabetes, hypertension, and kidney failure now kill more people than malaria, HIV, and TB combined in many African countries. Yet no predictive system exists to anticipate the next wave.

Of all deaths worldwide, 71% come from non-communicable diseases.

Cost of treatment vs. prevention

Every dollar on screening averts five in hospitalisation.

Three gaps define the crisis.

Preva AI closes all three — at population scale, on infrastructure that works from a Korle-Bu ward to a rural clinic in Bolgatanga.

Fragmented screening data

NGOs, churches, corporate wellness, district hospitals — all collect vitals. The data dies in notebooks and spreadsheets. Never aggregated. Never analyzed.

No predictive layer

A 42-year-old with BP 158/98, sugar 6.9, and family history of stroke is a walking emergency. Nothing in the current system flags him — until he arrives in a ward.

No feedback to citizens

People whose data is collected never hear back. They don't know their risk, their trajectory, or what to do next. Prevention fails at the last mile.

The Platform

Four integrated layers. One intelligence.

A nationwide data aggregation network, a governance and compliance engine, a purpose-built clinical form system, and an AI risk layer — engineered to work anywhere in Ghana.

Layer 01 · Preva Core

The command center for national health.

Governance and orchestration, operated in partnership with the national health authority. Vet and onboard aggregators, run KYC and ethical compliance, publish intelligence to MoH, WHO, and donors.

Behind every score, a life.

From a nurse in Tamale capturing vitals via USSD, to a daughter in Kumasi checking her father's risk on her phone — Preva AI exists because these moments matter. And because "knowing early" has a face.

Security & Ethics

Trust, engineered in. Not bolted on.

Preva AI is registered with Ghana's Data Protection Commission and engineered for full compliance with the Data Protection Act (2012, Act 843). Data lives on Ghanaian soil. Consent is explicit and revocable. De-identification is the default, not the exception.

Act 843

DPC Registered & Certified

Ghana Data Protection Act compliance from day one.

Residency

Ghanaian sovereign cloud

Data never leaves local jurisdiction or infrastructure.

Encryption

AES-256 · End-to-end

TLS 1.3 in transit · encrypted at rest · key rotation.

Audit

SOC 2 Type II · Ready

Continuous audit with independent third-party review.

Consent as a living contract

Every data subject gives explicit, granular, revocable consent — captured in Preva Forms, mirrored in USSD, auditable in Core. We don't repurpose. We don't re-share. We don't ask forgiveness.

De-identify at the edge

PII is stripped the moment a form syncs from device to server. Re-identification keys are held separately, encrypted, and released only to return results to the individual — under audit.

Sovereignty by design

Ghanaian data remains on Ghanaian infrastructure. Redundant. Resilient. Under local legal jurisdiction. No foreign sub-processors without explicit, disclosed approval.

AI-powered health intelligence for Africa.
