As reported in the Ottawa Citizen, syphilis has seen a 400 percent increase over the past five years. In Ottawa, cases increased from 30 in 2013 to 159 in 2018. As recently as 2000, there was only one case in the city.

It was once so rare that many health providers working today have never seen a case of syphilis.

Syphilis is a sexually transmitted infection (STI) caused by the bacterium, Treponema pallidum. The most common way to get syphilis is by having sexual contact (oral, genital or anal) with an infected person. The secondary lesions are also infective and contact with them could transmit the bacteria. It can also be transmitted from an infected mother to her baby (congenital transmission).
