**Household contacts of people with pulmonary tuberculosis are at increased
risk of infection and disease**, and the honest starting point of this report
is that **effective interventions to improve case finding and increase the use
of preventive treatment are lacking.**
A pilot project at six health facilities in Uganda tried a package.
What it produced
| Index patients with TB disease enrolled | 521 |
| Household contacts identified | 1,913 |
| Screened for TB | 90.9% |
| Started preventive treatment | 1,239 |
| Completed it | approximately 95% |
| New TB cases diagnosed | 80 |
Ninety-five per cent completion of a months-long preventive course is a
remarkable number for any health system.
What was in the package
- Home visits
- Chest radiography
- Adherence counselling
- Travel reimbursements
The fourth item is the one worth pausing on. Three of these are clinical; one
is money for a bus fare.
Preventive TB treatment fails at the point where a well person, with no
symptoms, has to keep travelling to a clinic for months to take medicine for a
disease they do not have. The cost of getting there is not a minor
inconvenience in that calculation — it is often the whole of it.
Including travel reimbursement in the intervention treats the barrier as what
it actually is, and the 95% completion rate is the result.
Why it matters beyond Uganda
Progression from untreated latent infection to disease is how most TB cases
happen. **Global scale-up of this household contact approach might help reach
global TB elimination goals** — and the 80 new cases found among contacts show
the case-finding half working alongside the prevention half.
