This week is National Influenza Vaccination Week (is there a Hallmark card for that?), which got me wondering whether urban dwellers have better immune systems because they’re exposed to so many people–and germs. After all, a subway car is not too dissimilar to a daycare center: uncovered coughs, shoving, and issues with sharing abound. And we know that in the long term, kids in daycare have stronger immune systems.
Without spending too much time researching this question, I came across an interesting National Geographic piece that illustrated the impact ancient cities have had on bolstering present-day immunity. At the same time, however, a quick glance at this Google Map tracking the spread of H1N1 reminds us that urban areas were particularly hard-hit.
