Host evidence

Counts of nucleotide records annotated with that host. Evidence of provenance, not a statement of host range.

Where it occurs

Not searched yet. No country-level occurrence data has been curated for this virus. The WHO reported-case data on this site covers a limited set of diseases; a virus outside it gets no map rather than an empty one.

FINDINGS: Globally in 2020, there were an estimated 604 127 cervical cancer cases and 341 831 deaths, with a corresponding age-standardised incidence of 13·3 cases per 100 000 women-years (95% CI 13·3-13·3) and mortality rate of 7·2 deaths per 100 000 women-years (95% CI 7·2-7·3).

Lowest and highest vaccine effectiveness reported: 17% (FUTURE II Study Group 2007 N Engl J Med; All high-grade cervical lesions regardless of HPV type, 15 to 26 years) to 100% (Lehtinen M 2012 Lancet Oncol; CIN3+ associated with HPV-16/18, 15 to 25 years). Two of 38 estimates, each from its own study; not a summary figure.

Type 16 is the cause of approximately 50% of cervical cancers worldwide, and types 16 and 18 together account for about 66% of cervical cancers.

women diagnosed with CIN3 in 1955-76 (adult), New Zealand; vs women whose initial CIN3 treatment was adequate (0.7% at 30 years)
quote
In 143 women managed only by punch or wedge biopsy, cumulative incidence of invasive cancer of the cervix or vaginal vault was 31.3% (95% CI 22.7-42.3) at 30 years, and 50.3% (37.3-64.9) in the subset of 92 such women who had persistent disease within 24 months.

New cancer cases attributable to HPV

all ages, global; vs cancers not attributable to infection
quote
The largest number of cases was attributable to H pylori (n=760 000, PAF 4%), followed by HPV (n=750 000, 4%), HBV (n=360 000, 2%), EBV (n=260 000, 1%), and HCV (n=160 000, <1%).

When problems appear: after the infection, and after the vaccine

Two separate clocks on the same logarithmic scale. The first starts at the infection and shows when its sequelae are described as beginning; the second starts at the dose and shows when the vaccine's adverse events are described as beginning. Each bar is one source's printed window, not a synthesis; hover for the source.
