It's often said--not without reason--that technology is the solution to infectious disease.
However, microbes can exploit that very technology to find routes into the body. Witness prosthetic joint infections, for example.
The fact is that just as we use technology to enhance our lives, so do microbes.
Case in point: the exploitation of hook-up apps by syphilis. By facilitating sexual encounters such apps also facilitate syphilis transmission.
Talk about a 21st century problem.
