“Ten Dreaded Diseases Reappear”
We have witnessed a reappearance of many dreaded diseases. Once effective treatment or prevention exists for a disease, the hope is that the disease will fade from public health. But illnesses don’t always go away and can lurk in the shadows only to later re-emerge. Some of these diseases reappear because people fail to get vaccinated while others evolve to become more virulent and resistant to current treatments. Let’s look at 10 diseases that have been making a comeback in recent years. 1) Syphilis. Syphilis used to be a lot less prevalent, but this sexually-transmitted infection (caused by Treponema pallidum) has been on the rise in the 21st century. Fortunately, syphilis is susceptible to treatment with penicillin. 2) Measles. With more parents foregoing vaccination for their children, measles has again reared its ugly head. Just in 2019 so far, 79 cases have already been reported—compared with 63 cases in the entire year of 2010, according to the CDC. 3) Plague. Plague—or the “Black Death” as it was referred to in the Middle Ages—is making a comeback in the developing world and in parts of the United States, including Idaho, California, Arizona, Colorado, and New Mexico.
