Multinational pharmaceutical company MSD recently paid homage to Nobel laureate Dr. William Campbell for his groundbreaking work in identifying a new treatment for parasitic infections. Dr.
Campbell’s discovery has helped to alleviate the suffering of millions of people around the world.
Background
Parasitic infections are a major public health issue in many developing countries. They can cause a wide range of debilitating and potentially fatal conditions, including river blindness, African sleeping sickness, and elephantiasis.
Dr. Campbell began his research in the 1970s while working at the Merck Institute for Therapeutic research. He was tasked with finding a treatment for river blindness, which is caused by infection with the parasitic worm Onchocerca volvulus.
The Discovery
Dr. Campbell’s research team discovered a new class of compounds called avermectins, which were found to be highly effective against parasitic infections.
The researchers focused on one particular avermectin called ivermectin, which was found to be particularly effective against river blindness.
The discovery of ivermectin revolutionized the treatment of parasitic infections. It was highly effective against a wide range of parasitic worms and could be administered in a single dose, making it much easier to use than previous treatments.
The Impact
The impact of Dr. Campbell’s discovery has been immense. According to the World Health Organization, over 210 million people have been treated with ivermectin since its introduction in 1987.
This has helped to significantly reduce the incidence of parasitic infections in many parts of the world.
In addition to its role in treating parasitic infections, ivermectin has also been used to treat a range of other conditions, including scabies and head lice. It has also been used in veterinary medicine to treat parasitic infections in livestock.
