Diseases, Conditions, Syndromes (Medical Xpress) -- The incidence of condyloma
or genital warts (GW) is significantly declining in young women, according to a
novel register study from Karolinska Institutet. The researchers suggest that
this recent development may be explained by the introduction of the national
HPV vaccine program in Sweden .

to as anogenital warts or condyloma acuminate, are highly infectious and
transmitted sexually primarily through skin-to-skin contact. Over 90 percent of
GW are caused by Human papillomavirus (HPV) types 6 and 11. The introduction of
HPV vaccines have made the estimation of population-based incidence of
condyloma immediately prior to and following vaccination uptake necessary for
the evaluation of vaccine programme effectiveness. In the current study, which
is published in the Journal of Infectious Diseases, incidence proportions were
calculated using the entire population of men and women living in Sweden
between 2006-2010 ages 10-44. To define episodes of GW the drug prescription
and patient registers were used. The results show that women ages 17 and 18
years had over a 25 percent decline in GW rates when comparing 2006 with 2010,
with significant decreases through age 25. Incidence among men did not decline,
indicating no possible herd immunity effects during this period. More
