Disease Transmission

Here we provide details on the circumstances where Lyme borreliosis (Lyme disease) is reportable.

England & Wales

Lyme borreliosis is monitored in England and Wales through:

  • Passive surveillance. Cases of Lyme borreliosis are not statutorily notifiable by medical practitioners in England, Wales and Northern Ireland. However, since October 2010, under the Health Protection (Notification) Regulations 2010, every microbiology laboratory (including those in the private sector) in England is required to notify all laboratory diagnoses of Lyme borreliosis to the Zoonoses Surveillance Unit at the National Public Health Service (NPHS), Wales. Previously, reporting by laboratories was on a voluntary basis.
  • Enhanced surveillance. This was introduced in late 1996 as a means to collect additional clinical and epidemiological data and improve reporting levels. Since August 2000, a single reference laboratory has existed for England and Wales which provides specialised tests for Lyme borreliosis. These tests were previously provided by the Health Protection Agency (HPA) Lyme Borreliosis Unit (LBU) but are now provided by Public Health England's Rare and Imported Pathogens Laboratory (RIPL). The RIPL reports all laboratory-confirmed cases directly to the Zoonoses Surveillance Unit at the National Public Health Service (NPHS), Wales.Between 1997 and 2003, the HPA LBU sent questionnaires to clinicians requesting additional data on laboratory-confirmed cases. The data collected helped to enhance knowledge of the disease in the United Kingdom.

Public Health England states that, "Reporting levels have improved, but the data remain incomplete because they do not include cases diagnosed and treated on the basis of clinical features such as erythema migrans (the early rash of Lyme borreliosis), without laboratory tests. It is estimated that between 1,000 and 2,000 additional cases of LB occur each year in England and Wales".

Scotland

In Scotland, cases are New window: notifiable by diagnostic laboratories. Health Protection Scotland states that, "The true incidence of the disease is unknown due to incomplete detection and reporting of cases".

Northern Ireland

In Northern Ireland, voluntary reporting is made to the Public Health Agency. The annual incidence according to reported cases is low but, as with other voluntary surveillance systems, the Public Health Agency recognises that cases are likely to be under recorded.

The Republic of Ireland

From September 2011, Lyme disease was listed as a New window: notifable disease in the Republic of Ireland, where clinicians should notify cases to the Director of Public Health/Medical Officer of Health for the area of residence of the patient. Prior to it becoming a notifiable illness, there was no voluntary surveillance scheme and therefore the annual number of cases have been unknown.

The Health Protection Surveillance Centre (HPSC), Ireland, states that although the true incidence of Lyme disease is not known, it is likely that there are at least 50 – 100 cases in Ireland every year.

Occupational-acquired disease

Occupationally-acquired cases of Lyme borreliosis and other associated tick-borne infections should also be notified to the Health and Safety Executive (HSE). New window: The Reporting of Injuries Disease and Dangerous Occurrences Regulations 1995 (RIDDOR) apply to England, Scotland and Wales. These regulations require work-related accidents, disease and dangerous occurrences to be reported and this includes all work activities. It is the responsibility of employers and the self-employed to submit a report to health and safety enforcing authorities.

Occupationally-acquired Borreliosis is seldom reported (perhaps through lack of awareness of the regulations and through lack of diagnosis / misdiagnosis) but the majority of these cases occur in zookeepers, forestry workers, farmers, deer handlers and gamekeepers. Lyme borreliosis is also a reportable condition for those serving in the British Armed Forces.

The Social Security (Industrial Injuries) (Prescribed Diseases) Amendment Regulations 2005 include Borreliosis in the list of prescribed diseases. Evidence indicates that there is a greater than doubled risk of contracting Borreliosis in certain groups of workers who are exposed to Borrelia bacteria.

DACTARI

New window: DACTARI (Dog and Cat Risk Information), is part of DEFRA's (Department for Environment Food and Rural Affairs) ten-year veterinary surveillance strategy which aims to quantify the occurrence of exotic diseases in imported or native pet animals in Britain. This will thereby monitor the risks of these diseases spreading in the UK, and the potential consequences for animal health should this occur.

Under the DACTARI scheme, veterinary surgeons can voluntarily report suspected or confirmed cases of exotic disease in dogs and cats. Although any exotic disease can be reported under DACTARI, it specifically targets Babesiosis, Anaplasmosis / Ehrlichiosis, along with Dirofilariasis and Leishmaniasis. These diseases are carried and transmitted by ticks, sandflies or mosquitoes, and therefore occur more commonly in warmer climates that favour vector survival. It also highlights that the diagnosis of these diseases can be difficult for various reasons, such as dual infection, sub-clinical infection and non-specific clinical signs.
