11. What is TRUE about bacterial STIs? Modern antibiotics have almost eliminated these infections. The body's immune system can cure these infections if given enough time. These infections are becoming increasingly common in 15-to -29-year-olds in the U.S. These infections are manageable, but not curable.

## Step 1<br />The problem presents four statements about bacterial sexually transmitted infections (STIs). We need to determine which of these statements is true.<br /><br />## Step 2<br />The first statement suggests that modern antibiotics have almost eliminated these infections. This is not true because while antibiotics can effectively treat bacterial STIs, they have not completely eradicated them.<br /><br />## Step 3<br />The second statement suggests that the body's immune system can cure these infections if given enough time. This is also not true because while the immune system can fight off the infection, it does not guarantee a complete cure.<br /><br />## Step 4<br />The third statement suggests that these infections are becoming increasingly common in 15:to -29-year-olds in the U.S. This statement is true as the incidence of STIs, including bacterial ones, has been increasing in this age group.<br /><br />## Step 5<br />The fourth statement suggests that these infections are manageable, but not curable. This is not true because while bacterial STIs can be managed with treatment, they can be cured with the right antibiotics.
