Each week The Pulse showcases topical stories from around the world and from laboratories working on new cures, vaccines and treatments.

Anti-retroviral drugs

The Pulse travels to Bolivia to see how
 insecticides are being used to control Chagas
The World Health Organisation says there has been significant progress in getting anti-Aids treatment to people with advanced HIV infection in low and middle-income countries.

In 2006 there were over two million people living with HIV/Aids who received anti-retroviral treatment, a 50 per cent increase on the year before.

We visit Zambia to meet a patient whose life has improved after receiving the drugs.

Dr Harold Jaffe is in the studio to talk about the sustainability of these treatment programmes.


Chagas is a parasitic disease found in Latin America and spread by insects. It is estimated that 11 million people living in Mexico, Central and South America are infected without knowing it and it can remain symptom-less for decades. Eventually 30 per cent of people develop serious cardiac and intestinal problems. There is no cure.

We travel to Bolivia to see how health workers are using insecticides to control its spread and also how the disease has affected national blood supplies.
