Step-by-step explanation:
The odds of contracting a sexually transmitted disease (STD) in a lifetime can vary depending on various factors such as sexual behavior, the use of protection, and the prevalence of STDs in a particular population.
According to the CDC, in the United States, there are millions of new cases of STDs each year. Chlamydia and gonorrhea, for example, are two common bacterial STDs with a high number of reported cases. In 2014, the incidence of chlamydia was about 1.44 million cases, while the incidence of gonorrhea was about 350,000 cases.
It's important to note that the actual odds of contracting an STD in a lifetime can vary for individuals depending on their sexual behavior and other factors, so it's always important to practice safe sex and get tested regularly.
