Second Edition.Sexually Transmitted Diseases Concern Everyone Centers for Disease Control (CDC) estimates about 65 million Americans are living with a sexually transmitted disease (STD). About half of all people will be infected by an STD sometime in their lifetimes. More than 19 million new cases occur each year In the United States, almost half of them among young people aged 15 to 24. Each year, one in four teens contracts an STD. As many as one in four Americans have Genital Herpes, and up to 90% are unaware that they have it. Each year in the United States, more than $13 billion is spent on major STDs including human immunodeficiency virus (HIV). All STDs can be improved by treatment, and some can be cured, but many people who are infected don't recognize the symptoms. This book gives information primarily from official government medical sources on the most common STDs extant in the United States, including description of symptoms, more than 70 figures and photographs, what to do to reduce risk of exposure, and what to do if you think you might have been exposed. If you are concerned, then do something. Inactivity and ignoring information will not make it better. Buy this book and share it with your friends. Illnesses like STDs will only thrive in darkness and ignorance.
