Entry category: New metric
Entry description:

Data showing reported numbers of Ixodes ricinus ticks is now available.

The dashboard now shows data of tick records received yearly, monthly and the monthly average.

The data comes from the Tick Surveillance Scheme (TSS), set up in 2005 to map and monitor tick distribution. Data collected from the TSS informs UKHSA’s assessments of the public health impact of ticks.

Globally, ticks are one of the most significant disease vectors. A vector is a living organism, such as ticks or mosquitoes, that can transmit infections between animal or human hosts.
