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.
A trial vaccine for the prevention of COVID-19 is underway with the first US participants being dosed in the Phase 1/2 clinical trial. Known as the BNT162 vaccine programme, the trials are a collaboration between Pfizer Inc. and BioNTech SE, and is part of a global development programme with Germany and the US taking the lead in having the first cohorts to be vaccinated. Germany started the study 1 week earlier.
Rinsing with mouthwash that contains povidone-iodine (PI) or cetylpyridinium chloride (CPC) helps reduce SARS-CoV-2 levels in the saliva of COVID-19 patients, with the effect persisting for up to 6 hours, as shown in a study from Singapore.
