Flu season is at its peak, and with the polar weather showing no signs of taking a mild turn, people across North America are feelings its effects.

Just take a look at the Flu Near You map, which showed a spike in flu-activity for the week ending of January 14. The multicolored dots represent the more than 50,000 participants reporting flu-symptoms or illness, allowing the site to generate a crowd-sourced chart of the disease.

With the handy smartphone application, you can now track flu activity—and your own personal health—while you’re traveling or on the go.

Flu Near You is an offshoot of the HealthMap, which tracks infectious diseases across the globe. And if you’re still planning your winter getaway, it doesn’t hurt to take a peek. What could be a better way to keep a bad bug from ruining your trip than a little flu-foresight?

If you’re hopping across the pond, Influenzanet tracks the spread of the flu across ten major European countries.
