Which genotype of Human Papillomavirus is strongly linked to cervical carcinoma? _____________?
Show answer Hide answer
Answer: B. 16,18,31
Explanation
Human Papillomavirus genotypes 16, 18, and 31 are classified as high risk oncogenic types. Persistent infections with these specific viral genotypes are strongly associated with cervical carcinomas. Viral oncoproteins produced by these strains disrupt normal cell cycle regulation in host tissues. Oncogenic human papillomaviruses integrate their DNA into the host genome during malignant transformation. Cervical cancer is one of the most common malignancies affecting women worldwide globally. Prophylactic vaccines target these high risk viral types to prevent premalignant cellular changes.
Routine cervical screening programs utilize molecular testing to detect high risk viral genotypes early. Vaccination campaigns successfully reduce the incidence of cervical precancerous lesions in young adults. Gynecologists monitor persistent infections closely to prevent progression to invasive malignant tumors. Types 6, 12, and 18 group mixed low risk and high risk strains incorrectly. Types 6, 8, and 11 are typically associated with benign genital warts rather than carcinomas. Types 3, 10, and 19 represent lower risk strains rarely linked to invasive cervical cancers.
