GAINESVILLE, Fla. (AP) - The University of Florida is restricting student travel to Haiti because of a cholera outbreak in the Caribbean country.

In a memo released Sunday, Provost Joe Glover wrote that undergraduates may not travel to Haiti until public health conditions improve. Faculty and graduate students are discouraged from traveling to Haiti but may do so with university approval and if they carry personal rehydration kits.

The university banned travel to Haiti after an earthquake devastated the country in January. The policy was relaxed for faculty and graduate students in July, with some limits.

United Nations officials confirmed Tuesday more than 420 new cholera cases and 25 new deaths, bringing the total number of deaths to 284.
