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.

"Swine flu" symptoms, fever, nausea, headache, disentery, etc., are similar,
appropriate for concern about these air pollution scenarios.
