Answer 73

Once an STD is cured, reinfection will not occur, although latent organisms can cause recurrence of some of these diseases

Answer 74

With most STDs, when the symptoms go away, one can no longer be considered infectious, so transmission of the disease to a sexual partner is of little concern

Answer 75

The latest estimates indicate that 15 million Americans become newly infected with an STD each year, yet these diseases are one of the most under recognized health threats
