Infection with which two high-risk HPV strains has been linked to more than 70 percent of all cervical cancer diagnoses?
- HPV 6 or HPV 11
- HPV 31 or HPV 33
- HPV 16 or HPV 18
- HPV 45 or HPV 52
Show answer and solution
Correct answer: C. HPV 16 or HPV 18
1. Most HPV infections do not cause disease, but certain high-risk strains can cause precancerous cervical changes.
2. Among the many HPV strains, only a couple are responsible for the large majority of cervical cancer cases.
3. These two variants directly.
4. HPV 6 or HPV 11 and HPV 31 or HPV 33 are both different figures a reader might guess from memory, but neither matches the specific figure given here.
5. HPV 45 or HPV 52 is also incorrect for the same reason: it does not match the specific figure given here.
6. They are HPV 16 and HPV 18, together linked to over 70 percent of cervical cancer diagnoses.
