Alberta’s chief medical officer of health says he has been made aware of additional daycare sites in Calgary where children have tested positive for E. coli.

Dr. Mark Joffe (pictured) has issued a statement saying out of an abundance of caution, the additional facilities will be closed.

He says the sites will be required to be cleaned and sanitized and all children will be tested to confirm their negative status before returning to the centre.

The statement notes some of the children who have tested positive at the added centres are connected to daycares from the original outbreak.
