Abstract: According to embodiments, retrieved weather and environmental data from the various categories; AIR (Air Quality, Pollen) TEMP/HUM., WIND (Speed, Direction), and OUTLOOK (Cloud Cover, UV Index, and Barometric Pressure) is applied against evidence-based algorithms for estimating the increase in relative risk of onset symptoms for allergy sufferers or breathing difficulty for asthma patients based on the evidence indicating increased incidences of severe allergy impacts and asthma attacks or resultant ER visits or hospitalizations. These embodiments generate a risk index and specific impact summaries based on the increased relative risk reflected in an adjustment to the AQI and Pollen Count, which represent an estimate of the severity of the exposure, rather than the actual risk based on the patient condition.
