Did you know typhoid fever still exists and is still a very real threat in some areas of the world? The bacterial infection isn't as common as it was in the late 19th/early 20th century, but every once in a while, it rears it's ugly head here. I was awfully surprised to learn this when someone this morning mentioned a new case in San Francisco. I was even more surprised when I found out that I may have been exposed to typhoid because a food handler at a cafe I ate at 12 days ago has it. I have to spend the next two and a half weeks on the look out for symptoms of an infection from a bacteria I thought had been all but eradicated 100 years ago. HOW DOES THIS EVEN HAPPEN?
