Preventive measures urged in treatment of asthma

I was surprised that the article ''State study links asthma to economic circumstances" (Globe North, Sept. 18) did not mention that viruses, including respiratory syncytial virus, are a frequent precipitant for asthma, among those who are genetically predisposed.

Instead, the article seemed to link asthma to poor housecleaning and bad habits. One school nurse commented in the article that ''the home environment is something we're constantly evaluating with the families." I think we should avoid theories that blame parents, who must work hard and have many sleepless nights, keeping their asthmatic children safe.

Ironically, I have also read that asthma is increasing because our houses are too clean, that children's immune systems are not maturing properly as a result, and that we should throw out all those antibacterial soaps and sponges.

The most helpful avenue for physicians and school nurses is to make sure that inhalers and peak flows are being used properly. Many children do not wait a minute between puffs, for instance, or blow too lightly into the meter. Preventatives such as Intal or steroid inhalers make a dramatic difference, virtually eliminating asthma symptoms and susceptibility to triggers such as exercise, pollen, or dust.

Isn't it possible that asthma is being reported more frequently in poorer communities because schools lack funds for school nurses, or because the residents cannot afford health insurance or effective medications?
