As with a lot of Android malware, you generally have to go to a third-party store to get these corrupted apps. You'll likely be fine if you stick to Google Play. Lookout says it spotted over 20,000 modified apps, however, and some of the highest infection rates are in Google Play-friendly countries like Germany and the US. In other words, this isn't simply an issue in those regions where third-party stores are the only real sources for apps -- it's a global issue. These exploits take advantage of the same security holes that many people use to root their devices, so as long as those exist the problem may also continue. For now, the best bet is for people to be more cautious with their downloads.
