What about other HPV-related diseases?

About 360,000 people in the United States get genital warts each year. Most of these cases are caused by HPV-6 or HPV-11.

Recurrent respiratory papillomatosis (RRP) causes warts to grow in the breathing tubes (trachea and bronchi) and lungs. It’s very rare, but can happen when a pregnant woman with genital HPV passes HPV to her baby during delivery. RRP occurs in less than 820 infants and children in the US every year. It may lead to breathing problems, a hoarse voice (caused by laryngeal papillomatosis – when the warts grow in the larynx or voice box), or may rarely progress to cancer of the larynx. It is most often linked with HPV types 6 and 11.
