ExpandEbola Information for Health Care Professionals

Clinicians should be reminded that although the risk is extremely low Ebola virus disease (EVD) should be considered in the differential diagnosis of febrile persons who have returned from endemic regions or specific local areas of Ebola-affected countries as identified by the  Public Health Agency of Canada.

For the most up to date information on infection prevention and control, lab testing and initial assessment and management of the returning traveller visit the PHO EVD webpage.

Provincial directives, including the Directive for Primary Care, as well as an EVD Screening Tool for Primary Care Settingscan be found at Ministry of Health and Long Term Care EVD page

Toronto Public Health (TPH) has set up an Ebola Information Line for Health Care Professionals at 416-392-5311. The line is staffed during regular business hours Monday - Friday, 8:30 am to 4:30 pm. After hours, please call 311 and your call will be redirected to the After-hours Manager. 

ExpandLead in Consumer Products

recent case of lead toxicity in Ontario has been linked to the use of an Ayurvedic medicinal product purchased online. Health Canada posted a related alert regarding Ayurvedic products with high levels of lead, arsenic, and mercury.

Toronto Public Health recently investigated elevated blood lead levels in a group of family members. Spices (turmeric, red chili powder, coriander) brought over from Bangladesh by the family (un-labelled bags ground and purchased at a market) were identified as the likely source of the elevated blood lead levels.

Although exposure to lead among Canadians has declined significantly over the past few decades, health professionals are reminded that imported consumer products may be a source of lead and other heavy metals

Important information for health professionals:

  • Health professionals should consider testing BLLs in patients who are symptomatic (e.g. abdominal pain, anemia, tremor), and screening in children at risk (see Rourke Baby Record).
  • Blood lead levels (BLL) <10 ug/dL can have harmful effects on cognitive, cardiovascular, immunological and endocrine function.
  • At BLLs >10 ug/dL, the exposure source (such as imported consumer products) should be identified and removed, and BLLs repeated within 3 months.
  • Higher BLLs (>20 ug/dL) should prompt specialist referral for further assessment.
  • For further assistance with investigating potential sources of lead exposure where BLLs are >10 ug/dL, contact TPH at 416-338-7600.
