Significant increases in LGV in gay men from 2017 to 2019: latest PHE report
Simon Collins, HIV i-Base
Between 2018 and 2019 the number of clinical cases increased by 56% and laboratory diagnoses increased by 32%. This continues a similar trend from 2017 to 2018.
Although the number of tests also increased by 20% from about 10,500 to 12,600 (to include HIV negative men who were asymptomatic), the proportion of test with positive results also increased from 8.2% to 9.0% suggestion a real increase in transmission.
The report includes more detail on annual rates since 2011, age, HIV status, STI history, UK region and country of birth. It also notes that similar increases have been reported in other European countries including the Netherlands, France and Italy.
Although referring to social changes including reduced use of condoms and more frequent STI testing the report also refers to studies from 2016 and 2020 that suggest continued transmission might be explained by undiagnosed asymptomatic LGV infection. [2, 3]
