Germ Tracker culls symptom data from social media platforms and tracks the virus, via a map, as it spreads. Upon publication of this post, the site was "experiencing heavy user traffic" and politely excused any potential delays.
Help, I Have the Flu, developed by pharmaceutical start-up Help Remedies, is an app that scans your friends' Facebook statuses for references to "sneezes," "coughs" or "flu." If someone in your network is sick, you'll receive an alert that lets you know you might want to avoid contact with them for a few days.
Google's Flu Trends tracker is another data heavy site that, besides showing a spike in flu related searches, also shows that a majority of the U.S. is experiencing intense activity in reported flu cases. The Center for Disease Control's (CDC) map shows similar "widespread" flu activity across the U.S.
Fortunately, the CDC shows the District of Columbia - where I live - as having a "local" level of severity, which is the lowest in the country. However, I haven't got my flu shot yet and I just got done nursing my girlfriend back from a 5-day flu, so I'm playing with fire. Here's hoping all those vitamins and immunity boosters I've been downing do their trick.
