Question

which of the following statments is true?
you can tell if a person has an sti by looking at them
one may have no symptoms but still have an sti and pass it on
stis go away if left alone
symptoms are always present and noticeable

Explanation:

• STIs (sexually transmitted infections) often have no visible symptoms. So, you cannot tell if a person has an STI just by looking at them.
• Many STIs do not go away on their own. For example, viral STIs like herpes or HIV are lifelong infections (though with treatment, HIV can be managed). Bacterial STIs like chlamydia or gonorrhea need antibiotics to be cured.
• Symptoms of STIs are not always present. Some people can be asymptomatic carriers.

Answer:

one may have no symptoms but still have an STI and pass it on
