Administrators at a Union City elementary school announced Tuesday it has four more confirmed cases of swine flu.

Robert Waters Elementary School had already decided to close for a week following a swine flu confirmation the day earlier.

District officials say all the cases are from the same grade and there are no more suspected cases at the school. Health officials are urging people to stay home if they?re not feeling well. However, they are also telling residents not to worry.

The school is still planning to reopen next Tuesday.
