"So sometimes we do have people who have travelled outside of the Interior and they come back and they are seen by a physician and they believe perhaps they have measles, so we investigate them".
"Some of them said their parents were against vaccination because of unreliable sources of information that they received", Cadesky said.
"That's why we have different laws in every state: so the citizens of that state can decide how they want to run things", Zedler said.
"Action is coming", said Dix.
"I think we need to take steps in the future, but the step we can all take right now is to have children immunized, and that's what I'm encouraging everyone to do", he said.
Vaccinations are sparking debate among communities, after nine confirmed cases of measles in Vancouver and a public state of emergency in Washington State. The other case is unrelated. The disease can also be fatal.More news: Ozil might be in Arsenal comfort zone, says Wenger
Measles symptoms begin with a high fever, cough, runny nose and red eyes, followed by a rash that usually begins at the head and spreads to the rest of the body.
Measles is a highly contagious airborne viral infection that spreads by coughing and sneezing. But some doctors fear that eliminating states' religious exemptions won't adequately address the risk of outbreaks tied to geographic clusters of parents who are opting out of vaccinating their children.
Washington now allows vaccination exemptions for children at public or private schools or licensed day-care centers based on medical, religious and personal or philosophical beliefs. The Immunization of School Pupils Act requires parents or guardians to provide proof of vaccination before their child can attend school.
In hopes of reducing the possibility of future outbreaks, lawmakers in Olympia have proposed two measures to tighten the personal or philosophical exemption used to excuse children from vaccines necessary for school entry.
On Wednesday, B.C. Health Minister Adrian Dix said the province is considering a vaccination registry to better track who is immunized. But medical groups including the American Medical Association (AMA), the American Academy of Family Physicians and the American Academy of Pediatrics have for years opposed vaccine exemptions, except in cases where an allergic reaction or medical condition could make immunization unsafe. Adults born after 1957 who have no history of vaccination are recommended to receive one dose of MMR. Almost all states allow children to attend school even if their parents opt out of vaccines.
"Because the number is very small, I cannot speak to details for privacy reasons, but I can say that we would always monitor these cases closely and be in direct contact with those individuals".
