I cant find this one zombie movie I saw when i was younger

I can’t remember much of the movie but I remember a scene where a member of the group is handcuffed to a pipe or radiator or something and left there(cant remember the reason) and when they come back they find he turned because of a mosquito bite(so mosquitos transmit the zombie virus). Not sure if im blending movies in together but I think the group were military and they were trying to find the patient zero of the zombie outbreak. Movie should be at least 8-10 years old maybe even older.
