Outbreaks of asthma attacks and meteorologic parameters in Bahia Blanca, Argentina.

Although Bahia Blanca is a relatively small city, the large daily number of asthmatic patients treated is comparable with cities at least ten times its population. A 1-year study of correlation between the daily cases treated and various meteorologic parameters is presented. Asthmatic outbreaks are normally associated with a dramatic decrease in temperature, humidity, and pressure. This condition may favor the activity of airborne allergenics transported mainly by continental winds.
