Lyme disease on the rise in Montreal, but it's usually contracted elsewhere

The number of Montreal Island residents who were infected with Lyme disease jumped by 84 per cent last year from 2016, say authorities who are bracing for another big increase in the incidence of the tick-borne illness this summer.
However, officials with the Montreal Public Health Department note that only two Montrealers actually contracted Lyme disease on the island last year, with the all the others having been bitten by a tick in other regions of the province, Ontario or the United States.
