Hansen's Bacillus



The most ancient Hindu legends speak of this disease. Several characters from the Bible were afflicted by this same disease which was perceived with terror. In one of its books, Leviticus, Chapter XIII, Moses speaks of the disease in great detail stating that it spared no one: men, women or children.

Leprosy's scientific name is mycobacterium leprae humanum. It is also named "Hansen's disease" after its discoverer, G-A Hansen, a Norwegian researcher. He discovered the leprosy bacillus in 1873. It is a slowly developing cutaneous infection that is not very contagious. There are two kinds of leprosy: "the tuberculoid and the lepromatous". The first kind is its most common form.

How does leprosy spread? According to Father Damien de Veuster, ss. cc (1840-1889), having himself died from this disease, believed that "leprosy is contracted via respiration and inoculation. It is not contagious, but infectious. This can occur in different ways, for example : vaccination, contact of the bacteria with a wound, a scratch, wearing the same clothes worn by the lepers, sleeping in their beds, smoking the same pipe or using the same tools as the lepers." A noteworthy fact, the Religious Hospitallers of Saint Joseph took care of the lepers from 1868 to 1965, not one of these nuns ever contracted leprosy.

Beginning of the leprosy in New Brunswick

The most plausible theory that explains the appearance of leprosy in New Brunswick seems to be linked to two Norwegian men. La Florida, a schooner, was sailing between Caraquet and Quebec. Circa 1817, during one of its voyages, two Europeans got unboard to reach Chaleur Bay. As the trip progressed, the captain noticed that both travelers were covered in ulcers and emitted a putrid odour. The captain warned his crew to avoid them as he did not know which sickness had infected them.
The two travelers disembarked in Maisonnette. They had reached the region of Tracadie a few days later. Obviously, they stayed with Acadian families. Amongst these families, a woman named Scholastique Ursule Landry became infected and died of leprosy in 1828. Her husband also became infected and died in 1834. Her sisters, Isabelle and Françoise, as well as others, all died of this disease in their own homes before 1844. This oral tradition, also speaks of two Norwegian travelers that had escaped from a lazaretto in their homeland.

Acknowledgement of the disease by the Province of New Brunswick

Father Lafrance arrived in Tracadie in early 1842. He immediately noticed that a large number of people suffered from a strange disease that they called the "sickness" or "la maladie". He had himself studied medicine before joining the priesthood. He decided to inform the provincial government about the dangerous state of the disease that was taking hold of his parish. At the request of the government, he wrote a report to the province's Lieutenant-Governor in which he stated that this disease was similar to leprosy tuberculosis which had spread rampantly through Europe in the 18th century. Lazarettos had been constructed to stop the disease; hence, he suggested that a lazaretto be built in Tracadie and that an annual subsidy be granted for its upkeep.
He also asked that a committee be named with the authority to quarantine the sick suffering from leprosy. He obtained that which he seeked in the creation of a "Bureau of Health" which was the first of its kind in the province and in Lower Canada. Its members, Joseph Cunard, president, Francois Xavier S. Lafrance, chaplain and Charles J. Peters, received the authority to find a site that could welcome the sick of the region.
