Nova Scotia confirmed its first hospitalized case of swine flu, health officials said on Tuesday, adding that the patient is improving.

The province's total number of documented cases of the H1N1 influenza A virus, which first began circulating in Mexico in April, is 77.

In its statement, the Health Promotion and Protection Department said other cases are mild, and those affected are recovered or recovering.

"Given that more severe cases of H1N1 are being reported in other provinces and outside Canada, it was anticipated that more severe cases would happen here, and staff has prepared to respond appropriately," the statement said.

Four new cases have been reported since June 1.

Officials said it's safe for people to go to work and school, participate in school activities and to socialize if they do not have flu-like symptoms.

But if the symptoms are present, people are asked to stay home and have minimum contact with family members. If symptoms get worse, they should contact a doctor.
