A division bench of the Gujarat high court on Tuesday asked an expert committee to come up with suggestions to curb spread of malaria and dengue in the city.

The order came after government authorities filed an affidavit showing that cases of malaria had increased from 5,504 last year to 13,480 this year. The cases of dengue registered till August last year were 283, but against this, 439 cases have been registered this year.
