The Ugandan government says effort to eliminate river blindness
(onchocerciasis) have suffered setbacks from recurrent cross-border
transmissions from neighboring South Sudan and the Democratic Republic
of Congo.

Addressing a meeting held to evaluate progress towards the elimination
of river blindness in Kampala recently, Uganda Onchocerciasis
Elimination Expert Advisory Committee head Dr Edridah Muheki said
long-running conflicts in her neighbors have complicated Uganda's
disease control efforts.

"The Uganda (river blindness control) programme has been active for a
long time and we are headed for elimination of the disease.

"However, South Sudan and DR Congo have not had stable disease control
programmes for years. There have been cross-border transmissions and
that affects progress in Uganda. We are strengthening cross-border
collaborations to enhance disease control," Dr Muheki said.

Civil wars, banditry and militia activity in the DR Congo and South
Sudan have stalled government epidemiological studies to establish the
prevalence of river blindness.

Health Minister Dr Ruth Aceh said it is critical for Uganda to work
with her conflict-ridden neighbours to control river blindness, which
remains prevalent along the common borders.

To fill up the epidemiological data gaps, the World Health
Organization (WHO), Uganda, DR Congo and South Sudan are undertaking a
mapping exercise to establish disease prevalence.

Among other uses, the findings will help inform a government mass drug
administration program that is due to be rolled out in endemic areas.

River blindness is spread by the black fly which inhabits and
reproduces in fast-flowing water bodies and humid forests. An
estimated 90 percent of the annual cases occur in Africa.

[Onchocerciasis -- African river blindness -- is caused by infection
with the nematode _Onchocerca volvulus_, transmitted by black flies,
_Simulium_ spp. Control programs have used insecticide spraying and
mass treatment with ivermectin every 6 months. Ivermectin reduces the
microfilaria load in the skin and treatment of all refugees arriving
into Uganda would probably be the best method to handle an influx of
cases.
