Quebec's public health department is reassuring parents about sending their children to school amid a potential second wave of the swine flu.

Health officials say rather than close schools, which would simply transfer the problem into the community, children should attend school as long as they don't have any flu-like symptoms.

In school, they'll receive the most education about preventing the illness, said Quebec Director of Public Heath Prevention, Horatio Arruda.

"The benefits of keeping people at school - giving them education and also not being elsewhere, and in daycare centres - is higher than if we stop," said Arruda.

Meanwhile, the province says it could be a while before an H1N1 vaccine arrives in the province.

"We think the first dose will come in November, and (it will take) around four weeks to six weeks to get all we need in Canada, including Quebec," said Arruda.

Health officials are still discussing a policy concerning pregnant women, including teachers, but an existing program called Maternity without Danger would allow preventive leave on a case-by-case basis.
