Summary of the Article: Resurgence of Measles and Rise in Congenital Syphilis in Canada
This article details the recent resurgence of measles and the increasing rates of congenital syphilis in Canada, particularly in Quebec.Here’s a breakdown of the key points:
Measles:
* Historical Context: Measles has a long history, first documented in the 10th century, and arrived in America in the 19th. Canada declared it a reportable disease in 1924.
* Elimination & Re-emergence: Canada successfully eliminated endemic measles transmission in 1998 thanks to widespread vaccination. However, outbreaks in 2023, especially in Alberta and Ontario (over 2000 cases), have led to the loss of this status.
* Vaccination is Key: Dr. Quach-Thanh emphasizes that 95% vaccination coverage is needed for collective immunity. Current coverage in quebec varies, with some regions falling below this threshold (as low as 83%).Imported cases can spread locally when vaccination rates decline.
syphilis:
* Uncertain Origins: The origins of syphilis are debated, with theories linking it to Columbus’s voyages.
* Rising Cases: Syphilis is increasing in Quebec, with 1,258 cases reported in 2022 (nearly 700 in Montreal) and 14 cases of congenital syphilis.2023 data is expected in 2026.
* Disproportionate Impact & Growing Concern: while syphilis disproportionately affects gay men, cases are rising in the heterosexual population, particularly among women of childbearing age. The increase in congenital syphilis – babies born with the infection – is particularly alarming, as its preventable with maternal testing and treatment. Dr. Quach-Thanh highlights the concern that mothers are not receiving adequate care or testing during pregnancy.
In essence, the article highlights the importance of vaccination for measles prevention and the need for improved access to prenatal care and STI testing to combat the rise in congenital syphilis.
