On June 4th, 1988, Health and Welfare Canada reported: (please see pictures above)
'Transplacental transmission of B. Burgdorferi(Lyme) has been documented and may be associated with an increased risk of adverse pregnancy outcomes.'
We are deeply concerned that this serious alternate mode of transmission of Lyme disease and potentially other co-infections has not been adequately addressed since this report. It has been 29 years since this report was published and yet most physicians and general public are completely unaware of the potential for mother to child transmission of Lyme disease. We know of many families whereby all the children have Lyme disease and the parents are concerned it was passed through pregnancy. We believe mother to child transmission to be an urgent research priority.
This same report can be found in: Lyme disease in Canada. Epidemiologic Report. CMAJ Vol. 139, Aug 1, 1988.
