I would like comments on my environmental study of "Swine flu", presented here. NYC (my home town) is the US epicenter. I'm considering the recent time period of 4/22 - 4/29/2009 Two main epicenters listed for NYC are reviewed below. Epicenter #1 Google map keywords: "St. Francis Preparatory School" Queens Note (satellite view) strictly adjacent are three expressways and traffic loops and NW is the La Guardia main take-off lane directly in line. Epicenter #2 Google map keywords: "Rye School" Westchester Note (satellite view) strictly adjacent are two expressways and loops. Weather conditions for Queens In the week of the emerging "Swine Flu" epidemic, note that on April 22nd wind moved to zero mph, stayed slow and then again to zero mph on 24th, the day when many students "suddently lined up at the nurse's station with nausea", etc. Usuallly, wind averages are closer to 10mph. Air pollution could not disperse away from school, and would concentrations would increase from vehicular exhaust. Temperature is very high, and high temperature defeats exhaust convection, leading to higher ground-level pollution. Wind direction is from the three adjacent expressways. Examples Misc Other epicenters mentioned in the media are "Mexico City", "New Jersey", "Austin Texas", which if looked into (weather and location) may find similar environmental causations. Symptoms "Swine flu" symptoms, fever, nausea, headache, disentery, etc., are similar, appropriate for concern about these air pollution scenarios.
