Quycy Day Care will be closed on Monday after a student was diagnosed with typhoid earlier this week, the daycare operator said, but could start later in the week.
"We can hire replacement teachers for the kids," said Bridget Perry, a Bright Horizons spokeswoman.
The daycare was not closed by any state authority. Instead, it was closed because both teachers and students have to go through a long test process before they can return.
"It's a staffing problem, which is why we're not open," Perry said.
Childcare facilities are being provided to students in other North Quincy Bright Horizons classrooms who are not potentially exposed to typhus, she said. The children in the daycare range from toddlers to five-year-olds.
After the student was diagnosed at the beginning of the week, the administrators closed the center. All the teachers who came into contact with the student must be tested, as well as all the children who were in the same classroom.
Before returning, students and teachers must pass three separate 48-hour typhoid tests. The test process is lengthy because bacteria take several days to grow in the body.
"Testing will take a while," said Ann Scales, a public health spokeswoman.
Typhoid fever can cause temperatures of up to 1
Massachusetts saw 20 cases last year, Skales said.
Typhoid fever is usually contracted overseas, and is more common in areas where sewage can contaminate the water supply centers for disease control and prevention. The disease is generally transmitted through food or water and can be treated with antibiotics.
