La Paz, Aug 6 (EFE) A doctor has died from influenza A (H1N1), better known as swine flu, raising the death toll from the disease in Bolivia to 12, the health ministry said.

The physician was treated for more than three weeks but did not recover, health officials said Wednesday.

The doctor died in La Paz, but she caught the flu while treating patients at a hospital in the Andean city of Oruro, health ministry epidemiology director Eddy Martinez told EFE.

The physician was taken from Oruro to La Paz July 16 for treatment, Martinez said, adding that she might not have sought medical care in time and the case was under investigation.
