Lyme disease is a tick-borne illness caused by the Borrelia burgdorferi bacteria. It is commonly found in parts of the United Kingdom, the United States of America, and Asia. While Lyme disease is not endemic in Australia, it can be acquired overseas and diagnosed in Australia. There is no evidence that the Borrelia burgdorferi bacteria is present in Australian ticks, and the Australian government does not support the diagnosis of locally acquired Lyme disease. However, some Australians suffer from chronic debilitating illnesses with symptoms similar to Lyme disease, which they associate with tick bites. This condition is referred to as Debilitating Symptom Complexes Attributed to Ticks (DSCATT).

What You'll Learn
Lyme disease is not endemic to Australia
Lyme disease is a tick-borne illness caused by the bite of an infected tick carrying the Borrelia burgdorferi sensu lato (B. burgdorferi s.l.) bacteria. It is commonly found in parts of the United Kingdom, the United States of America, Europe, and Asia.
Despite several reports of putative cases and discussions across several decades, there is no convincing evidence that classic Lyme disease occurs in Australia. The Australian government does not support the diagnosis of locally acquired Lyme disease. This is because scientists have not found the Borrelia burgdorferi bacteria in Australian ticks or any other Australian insects that could pass the disease to humans (vectors). In 1991, B. burgdorferi s.l. could not be confirmed in any of the 176 tick species examined, and the findings of more recent surveys have also been negative.
While Lyme disease is not endemic to Australia, it can be acquired overseas and diagnosed in Australia. Most people presenting with laboratory-confirmed Lyme disease in Australia were infected in Europe. However, there is a lack of awareness about the risk of acquiring Lyme disease when travelling to endemic areas, and some travellers may not seek medical attention for a tick bite or may not recognise the early symptoms of Lyme disease.
Some Australians suffer from the symptoms of a chronic debilitating illness, which many associate with a tick bite. This group is described as having Debilitating Symptom Complexes Attributed to Ticks (DSCATT). The validity of the term "chronic Lyme disease" remains contentious, and there is a lack of supporting evidence for its existence in Australia.

Lyme disease is caused by the bite of an infected tick
The Australian government does not support the diagnosis of locally acquired Lyme disease as the causative agent, B. burgdorferi, has not been found in Australian ticks or any other insects that could transmit the disease (vectors). However, some Australians suffer from symptoms similar to those of Lyme disease, which has been termed Debilitating Symptom Complexes Attributed to Ticks (DSCATT). This group of patients experiences debilitating symptoms that some attribute to tick bites, but the connection is not yet recognized by the Australian government.
The controversy surrounding Lyme disease in Australia extends beyond the presence of B. burgdorferi s.l. and competent tick vectors. There is also debate about the existence of chronic Lyme disease in the country. Some Australians believe they have chronic Lyme disease, but this diagnosis is disputed due to a lack of supporting evidence. The validity of the term "Lyme disease-like illness" is also questionable as it suggests that chronic Lyme disease is a recognized diagnosis, which it is not.
Despite the lack of evidence for locally acquired Lyme disease in Australia, it is important to take precautions when traveling to areas where ticks are prevalent. Protective measures include wearing long-sleeved shirts and long pants tucked into socks. Additionally, it is crucial to seek medical attention if you experience any symptoms indicative of Lyme disease or other tick-borne illnesses.

Lyme disease can be acquired overseas and diagnosed in Australia
Lyme disease is a tick-borne illness caused by the Borrelia burgdorferi sensu lato (B. burgdorferi s.l.) complex, a group of four types of bacteria. It is transmitted when an infected tick bites a human and can lead to serious symptoms if left untreated. While Lyme disease is commonly found in parts of the United Kingdom, the United States of America, Europe, and Asia, it is important to note that the disease is not endemic in Australia.
In Australia, there is no convincing evidence of the presence of classic Lyme disease, and the Australian government does not support the diagnosis of locally acquired Lyme disease. The causative agent, Borrelia burgdorferi, has not been found in Australian ticks or any other insects that could transmit the disease to humans. However, this does not mean that Australians cannot acquire Lyme disease.
It is possible for Australians to contract Lyme disease while travelling overseas to endemic areas and then be diagnosed back in Australia. In fact, most people presenting with laboratory-confirmed Lyme disease in Australia were infected in Europe. Therefore, if you are an Australian planning to travel to areas where ticks are prevalent, it is essential to take precautions to protect yourself from tick bites. This includes wearing appropriate clothing, such as long-sleeved shirts and long pants tucked into socks.
If you suspect that you or someone you know may have Lyme disease, it is crucial to seek medical attention. Australian healthcare providers are equipped to diagnose and treat Lyme disease. Testing for Lyme disease should be performed by an Australian laboratory accredited by the National Association of Testing Authorities, Australia (NATA). While there is currently no vaccine available to prevent Lyme disease, confirmed cases can be effectively treated with a short course of commonly available antibiotics.

There is no vaccine to protect against Lyme disease
Lyme disease is a bacterial infection transmitted through tick bites. It is caused by the bacterium Borrelia burgdorferi, which is spread to people by the bite of an infected black-legged tick. The risk of Lyme disease increases the longer a tick remains attached to a person, with the risk considered small if the tick is attached for less than 72 hours.
While Lyme disease is commonly found in parts of the United Kingdom, the United States of America, and Asia, it is not recognised as being locally acquired in Australia. The Australian Government does not support the diagnosis of locally acquired Lyme disease as the Borrelia burgdorferi bacterium has not been found in Australian ticks or any other Australian insect that could pass the disease to humans. However, some people in Australia believe that a form of 'chronic Lyme disease' exists in the country, and it is possible for visitors to Australia to contract Lyme disease abroad and return with it.
Currently, there is no vaccine to protect against Lyme disease. The only vaccine previously marketed, LYMErix, was discontinued by the manufacturer in 2002 due to insufficient consumer demand. LYMErix was only about 75% effective in blocking the disease, required three doses for full protection, and was only effective against the predominant North American Borrelia strain. Furthermore, protection from the vaccine decreased over time, leaving previously vaccinated individuals unprotected against Lyme disease.
Despite these drawbacks, the development of a Lyme disease vaccine is still being pursued. Clinical trials of new vaccines are currently underway, with a vaccine candidate, VLA15, developed by Valneva and Pfizer, currently in Phase 3 human trials. VLA15 is designed to protect against North American and European strains of the Lyme disease bacterium. In addition, the University of Massachusetts Medical School's MassBiologics has developed a human monoclonal antibody designed to be used as pre-exposure prophylaxis for Lyme disease. Researchers at the Yale School of Medicine are also reporting promising results from animal studies with a vaccine that teaches the body to recognize tick saliva and send an immune response to the site of a bite before the bacterium is transmitted.

Lyme disease is also known as Lyme Borreliosis
Lyme disease, also known as Lyme Borreliosis, is a bacterial illness transmitted to humans through the bite of infected ticks. The disease is caused by bacteria in the family Borreliaceae, particularly Borrelia (Borreliella) burgdorferi s.l. Ticks become infected by feeding on animals that carry the bacteria in their blood.
The Borrelia burgdorferi sensu lato group includes four types of bacteria that predominantly cause Lyme disease. The bacteria are transmitted to humans through the bite of an infected black-legged tick. The longer a tick is attached, the higher the likelihood of contracting Lyme disease. If a tick is attached for less than 72 hours, the risk of infection is considered small.
Lyme disease is commonly found in parts of the United Kingdom, the United States of America, and Asia. Visitors to these areas can become infected and return to Australia with Lyme disease. However, the Australian government does not support the diagnosis of locally acquired Lyme disease. This is because the Borrelia burgdorferi bacteria has not been found in Australian ticks or any other Australian insects that could transmit the disease to humans (vectors).
Instead, the Australian government recognises that some individuals experience debilitating symptom complexes attributed to ticks (DSCATT). While Lyme disease is not recognised as locally acquired in Australia, Australian healthcare providers can readily diagnose and treat the disease in individuals who may have been infected elsewhere.
