　「If you consider risky sexual behavior a nonissue, remember this: Over one million people around the world acquire a sexually transmitted disease (STD) every day. '…We often hear the words herpes, gonorrhea, and chlamydia in a comedic context, but anyone who has an STD knows it's no laughing matter,' Superdrug explained. 'It's something you may have to live with for the rest of your life. It's scary. It's embarrassing. It's often confusing. But if you're one of those people, you're not alone. Not even close.' 」

　「One in two sexually active persons will contract an STI by age 25. …Researchers estimate that at least 80% of sexually active people will have an HPV infection at some point in their lifetime. CDC data for 2013–2014 show that about 42% of men and 40% of women aged 18-59 had genital HPV at that time. …About 1 in 8 people aged 14-49 in the U.S. has genital herpes. …Symptoms of genital herpes often go unnoticed. Most people with genital herpes—close to 90%—don't know they have the infection. Globally, researchers estimate that about two-thirds of the population under age 50—more than 3.7 billion people—are infected with HSV-1. Some 140 million people aged 15-49 are infected with genital HSV-1, primarily in the Americas, Europe and Western Pacific. …In 2015, rates of the three most common reportable STIs—chlamydia, gonorrhea and syphilis—reached a record high level. The approximately 1.5 million reported cases of chlamydia represent the highest number of annual cases of any condition ever reported to CDC. …Young people ages 15 to 24 years old accounted for 65% of chlamydia diagnoses and 50% of gonorrhea diagnoses in 2015.」And so on.
