Short answer

Passive surveillance collects ticks or reports submitted through routine encounters, such as specimens from the public, clinics, veterinarians or partner organisations.

At a glance

It can cover wide areas efficiently but is strongly shaped by who notices, submits and identifies ticks.

Key takeaways

• Submissions are not a random sample.

• Public participation can reveal unusual records.

• Metadata quality determines usefulness.

Information generated by encounters

Passive systems can gather many records without running continuous field collections. They are useful for public engagement and signals of changing distribution.

Interpretation needs caution

Areas with more awareness or easier submission may appear to have more ticks even when exposure is similar. Analysts should describe these biases and avoid treating raw submission totals as population density.
