Final answer:
HPV types 6 and 11 are the subtypes associated with genital warts, whereas HPV types 16 and 18 are associated with a higher risk of cervical cancer.
Step-by-step explanation:
The subtypes of HPV associated with genital warts are HPV 6 and 11. While HPV includes more than 200 different strains, HPV 6 and 11 are specifically known to cause genital warts in infected individuals. Genital warts are caused by these specific HPV strains, which are categorized as low-risk types. These strains do not typically cause cancer, but they can lead to the development of genital warts. These types are considered low-risk for cancer. In comparison, HPV 16 and 18 are high-risk cancerous strains associated with cervical cancer and other types of cancers. The Gardasil vaccine includes HPV types 6, 11, 16, and 18; types 6 and 11 cover about 90% of genital wart infections, whereas 16 and 18 are responsible for about 70% of cervical cancers.
