businessinsider.com: Infectious diseases seem to come and go, sometimes causing scary outbreaks, while other times seeming to disappear. But some infectious pathogens are always with us, lurking just below the surface of society.
Sexually transmitted diseases are one major group of diseases that make for ongoing hidden epidemics: In the United States alone, there are nearly 20 million cases of new sexually transmitted infections yearly, from just eight viruses and bacteria, according to data from the Centers for Disease Control and Prevention (CDC).
Perhaps 20 million new cases sounds like a high number. But because infections can persist for a long time, especially in people who aren’t aware they are infected, the number of existing infections at any given time is even higher, at 110 million, according to CDC researchers.
The eight most common STDs in the U.S. are chlamydia, gonorrhea, hepatitis B virus (HBV), genital herpes, HIV, human papillomavirus (HPV), syphilis and trichomoniasis. About 50.5 million of these current infections are in men, and 59.5 million are in women, according to the CDC’s 2013 report, in which the researchers looked at 2008 data.

People are often surprised to learn how common genital herpes (HSV-2) is. And looking at the data, about 42 million Americans would be in for a more personal “surprise” if they got tested for it today. To what extent is herpes common? Read on for genital herpes statistics that may surprise you. Fortunately, herpes is highly manageable and people who get it can still have healthy love and sex lives, as the data also shows. These numbers focus mainly on United States genital herpes statistics. Please also keep in mind that these statistics only account for genital herpes caused by the HSV-2 strain!

The human immunodeficiency virus (HIV), which causes AIDS, varies in prevalence from nation to nation. Listed here are the prevalence rates among adults in various countries, based on data from various sources, largely the CIA World Factbook.[1][2][3] As of 2009, it is estimated that there are 33.3 million people worldwide infected with HIV.[4]
Africa leads the world with respect to both HIV prevalence and total number of cases, with more than 24.5 million cases comprising more than 60% of the world’s HIV-positive people. The 19 countries worldwide with the highest prevalence of reported infections are all in Africa. South Africa is reported to have the largest population living with the disease, at well over 5 million people infected, followed by Nigeria in second place. India comes in third, with more than 2 million cases. This, however, is not due to a high prevalence rate, but to India’s large overall population. The prevalence rate of HIV in India is 0.3%, which is much lower than that of countries such as the United States (0.6%) and South Africa (18.10%).[1]
