There are about 130 known types of human papilloma viruses.

The finding involves papilloma viruses, best known for causing harmless warts.

Some experts believe genital infections with papilloma viruses are increasing at an alarming rate today.

There are no vaccines against human papilloma viruses.

There are 70 types of human papilloma viruses, but only 6 are associated with cervical cancer.

The papilloma viruses generally infect the mucous membranes during sexual intercourse.

While few scientists will say flatly that papilloma viruses do cause cancer, many see the evidence as suggesting strongly that they are a factor.

Currently, most women are not tested for papilloma viruses, Dr. Schoolnik said.

One of the most startling recent developments in the research has been the almost explosive increase in the known number of different papilloma viruses.

Dozens of Types Found in 80's The existence of human papilloma viruses has been known for many years.

Scientists who study papilloma viruses stress that the increasingly strong evidence has not proved that the viruses are sufficient by themselves to cause cancer.

Papilloma viruses are naturally widespread in the human population, and most such infections appear to have no serious consequences but eventually subside of their own accord.

The group estimates that the presence of papilloma viruses can be detected in at least 80 percent of biopsies of cervical cancer.

Instead, knowing that cancer is a complex, multistep process, they suspect that the papilloma viruses are important contributors to the deadly progression.

Federal scientists at the Centers for Disease Control in Atlanta say reported cases of genital infections with papilloma viruses have become increasingly common.

One area of particular interest is the study of human papilloma viruses (HPV) and their role in cervical cancers.

The vapor emitted as the wart tissue is destroyed is likely to contain material from the papilloma viruses that cause warts.

The hepatitis and AIDS viruses are considered far less likely than papilloma viruses to invade through the skin.

The scientists tested vapor emitted during laser surgery in animal tissues infected with papilloma viruses and in seven patients treated for warts.

Dr. Versteegen said the samples are washed carefully, so that the probes that remain are stuck onto papilloma viruses.

Dr. McDonnell said there was a nationwide epidemic of genital infections from several types of papilloma viruses.

Genital warts have been recognized as a sexually transmitted disease since ancient Greek and Roman times, but papilloma viruses were not actually identified until the 1930's.

Dr. Howley heads the cancer institute's laboratory of tumor virus biology, devoted mainly to the study of papilloma viruses and their role in human cancers.

Researchers found the thickener, carrageenan prevented human papilloma viruses (HPV) from attaching to cells in laboratory tests.
