Anogenital warts (condylomas) are caused by human papillomavirus (HPV) with >90% of the lesions caused by genotypes 6 & 11.
Patients who present with visible warts may also be infected with high-risk HPVs (eg types 16 & 18) which can cause subclinical lesions that are associated with intraepithelial neoplasia, cervical cancer and anogenital cancer.
Many HPV infections are subclinical, transient, and clear spontaneously within 12 months but may also remain latent and reactivate after several years.
Results of a study conducted by the Chinese University of Hong Kong (CUHK) revealed that patients who recovered from hepatitis B virus (HBV) infection are still at risk for hepatocellular carcinoma (HCC).
A US study suggests that expanding HIV screening to reduce undiagnosed infections and increasing access to care and treatment to achieve viral suppression are important to lessen HIV transmission. It is also imperative that prevention methods, such as condoms and pre-exposure prophylaxis, be easily accessed, particularly among young men who have sex with men (MSM) and MSM of colour.
