Summary
To highlight the geographical variation in the human papilloma virus (HPV) type distribution we performed an analysis of data published in international surveys. Changes in the validity of different HPV screening cocktails and estimations of the potential number of cases prevented by HPV specific vaccines were evaluated. Higher than average proportions of type 16 were found in northern Africa, of type 18 in Asia, of type 45 in sub-Saharan Africa and of type 31 in Central/South America. The impact of modifying the number of types in the screening cocktail tests would be small and probably irrelevant for screening programs. A vaccine including types 16 and 18 could potentially prevent 71% of cervical cancers worldwide, but its impact with regard to the percentage of cases potentially prevented would be higher in Asia and Europe/North America. In contrast, a vaccine containing the 7 most common HPV types would prevent about 87% of cervical cancers worldwide, with little regional variation.
Key words:
human papilloma virus – geographical distribution of HPV – prevention of HPV – vaccine – cervical carcinoma
