Some 168 students had a blood test at the DU medical centre on Wednesday. Of them, 13 were found infected with dengue, the official said.
However, students have demanded closure of campus and halls fearing the dengue outbreak.
Chhatra Union today handed over a memorandum, containing the demand, to the Vice Chancellor.
Dhaka University Central Students’ Union (DUCSU) Vice-President (VP) Nurul Haque Nur also extend his solidarity to the demand.
