What would cause reoccuring sickness in child: high fever, nasal/chest cong. seems to come on about every 6wks. neg for strep/flu. seasonal allergies?

Not allergies: Allergies would not cause fever. I would want to know the following: how old is the child? How long has this been going on? Any other lab work, specifically a blood count? Any other symptoms, such as swollen glands, sores in the mouth, rashes, joint swelling? How high is the fever? Recurrent fevers of unknown origin are sometimes referred to pediatric infectious disease specialists.

Dr Ali and another doctor agreed

Not likely: While allergies can cause nasal and chest congestion, they typically do not cause high fever. These symptoms are more likely the result of recurrent viral-type infections, especially if self-limited and resolving within 7-10 days of onset without intervention.

Dr Rhoads agreed

Viral infections: Allergies cause congestion, but do not cause fever. Viral infections (i.e. Common cold) are likely. Most kids get 4-12 colds each year. Symptoms may last a couple days to 2 weeks. Thus, some normal kids may be sick for half the year (2 weeks out of every 12 months)! if a child has siblings or goes to school/day care, they are more likely to get more infections. Talk with your doctor for more info.
