I obviously have too much spare time – but a welcome break from working on a Friday afternoon.
Preserve the bats! - the risk is insignificant. Culling the local population probably wouldn’t make a difference anyway.
The most recent case of rabies in a bat in Great Britain was in September 2017. This brings the total to 14 cases in over 15,000 tests since 1986.
I suggest that the prevalence of rabies in the UK bat population is so low, (<0.1%) that culling a local population will not have any significant effect on the overall risk to humans. Bat handlers should of course take precautions to prevent being bitten or otherwise coming into contact with bat saliva etc.
Perhaps of greater concern are wild deer. Deer cause numerous road traffic accidents each year. The AA website has a page on deer collisions and suggests deer cause 400 injuries per year. Although there are no accurate figures for road deaths caused by deer, the deer collisions project (yes there is a website - http://www.deercollisions.co.uk ) reports:
“ (deer) pose a safety hazard to road users, and lead to substantial damage to cars and numerous human injuries as well as a number of human fatalities in most years.”
This statement is apparently based on the number of collisions per year in the UK and comparison with German data on fatal injuries from deer collisions.
So, based on that information, clearly deer are deadlier than bats.
DEFRA’s guidance (Rabies Disease Control Strategy 2011) considers and dismisses the risk of infection from or transmission of the disease by bats. The guidance states: -
“European bat lyssavirus (EBLV) 2 has been detected at a low prevalence in Daubenton’s bats in the UK.”
“Bat Lyssaviruses: European Bat Lyssaviruses have, very occasionally, been confirmed in bats in the UK. However, the small likelihood of contact between people and bats (apart from bat handlers) make the human risk from this disease negligible. There are no known incidences of bat lyssaviruses becoming established in other, more risk-associated animal populations.”
“Bats: The risk of rabies passing between other mammals and bats is extremely low. Bat populations would continue to be monitored by a passive surveillance programme during a rabies outbreak”.
The gov.uk website https://www.gov.uk/guidance/rabies-in-bats updated last week also states the risk is very low.
