False

Explanation:

Diseases that are spread sexually are referred to as a sexually transmitted disease. Most of the sexually transmitted diseases caused by bacteria are curable by antibiotics if detected early during infection but STDs caused by viruses are mainly not curable.

Therefore symptoms of STDs can be detected early or late during infection and some STD's symptoms do not become life-threatening if detected early during infection.

Some curable STDs are syphilis, chlamydia, gonorrhea and some non-curable STDs are HIV, HSV or herpes. Therefore the statement is false.
