Lyme disease is a bacterial infection transmitted through tick bites. While it is commonly found in parts of the United Kingdom, the United States of America, and Asia, there is no convincing evidence that classic Lyme disease occurs in Australia. Although there are anecdotal reports of a Lyme-like illness in Western Australia, no published scientific literature confirms any cases within this region. The Australian government does not support the diagnosis of locally acquired Lyme disease as the bacteria responsible for Lyme disease, Borrelia burgdorferi, has not been found in Australian ticks.

Lyme disease is not caused by ticks in Western Australia
Lyme disease is a bacterial infection transmitted through tick bites. It is caused by the bacteria Borrelia burgdorferi, which is spread to humans through a tick bite. While Lyme disease is found in parts of the United Kingdom, the United States of America, and Asia, it is important to note that Lyme disease is not caused by ticks in Western Australia.
There is little evidence that classic Lyme disease occurs in Australia, and no evidence that the causative agent, Borrelia burgdorferi, is present in Australian animals or ticks. The Australian Government does not support the diagnosis of locally acquired Lyme disease, as scientists have not found the bacteria that carry Lyme disease in Australian ticks. This is despite growing numbers of patients, their supporters, and some politicians demanding diagnoses and treatment according to the protocols of the "chronic Lyme disease" school of thought.
While there have been over 500 reports of an Australian Lyme-like syndrome in the scientific literature over the last 25 years, the diagnoses of Lyme Borreliosis in these cases have been primarily based on clinical presentation and laboratory results of tentative reliability. The true cause of these illnesses remains unknown, and the potential existence of a Lyme-like disease in Australia remains to be defined.
It is important to note that Lyme disease can be acquired overseas but diagnosed in Australia. Most people presenting with laboratory-confirmed Lyme disease in Australia were infected in Europe. However, the risk of acquiring Lyme disease from a tick bite is considered small if the tick is attached for less than 72 hours.
While Lyme disease is not known to be caused by ticks in Western Australia, it is always important to take precautions to protect yourself from tick bites and to seek medical advice if you believe you have been bitten by a tick or are experiencing any symptoms of concern.

Lyme disease is contracted overseas but diagnosed in Western Australia
Lyme disease is a bacterial infection transmitted through tick bites. It is caused by the bacteria Borrelia burgdorferi, which results in a multi-organ disease with arthritic, cardiac, neurological, and dermatological manifestations. While there is no convincing evidence that classic Lyme disease occurs in Australia, it is possible for individuals to contract Lyme disease overseas and be diagnosed in Western Australia.
Western Australia has reported a novel Borrelia species in Australian ticks, and there are some Australian Ixodes spp. and Haemaphysalis spp. ticks whose geographical distribution matches that of the Australian Lyme-like cases. However, the true cause of these illnesses remains unknown, and there is no evidence that the causative agent, Borrelia burgdorferi, is present in Australian ticks.
The Australian government does not support the diagnosis of locally acquired Lyme disease due to the lack of scientific evidence. Instead, it recognizes that a group of people experience debilitating symptom complexes attributed to ticks (DSCATT). Despite this, growing numbers of patients, their supporters, and some politicians demand diagnoses and treatment according to the protocols of the "chronic Lyme disease" school of thought.
It is important to note that Lyme disease can have serious consequences if left untreated. If you think you have been infected, it is crucial to seek medical attention. Doctors in Western Australia can examine you, consider your travel history, and perform blood tests to confirm a diagnosis and provide appropriate treatment.
While the risk of contracting Lyme disease in Western Australia is considered low, it is always advisable to take precautions when outdoors, such as wearing appropriate clothing and using insect repellents, to reduce the risk of tick bites and potential exposure to Lyme disease or other tick-borne illnesses.

Anecdotal reports of Lyme-like illness in Western Australia
Lyme disease is a tick-borne bacterial infection that is not believed to exist in Australia. The Australian government does not support the diagnosis of locally acquired Lyme disease as the causative pathogen, Borrelia burgdorferi, has not been found in Australian ticks.
However, there have been anecdotal reports of Lyme-like illness in Western Australia. While no cases have been published in the scientific literature, some people believe that a form of "chronic Lyme disease" exists in the region. This diagnosis is disputed due to a lack of supporting evidence.
In the last 25 years, there have been over 500 reports of an Australian Lyme-like syndrome in the scientific literature. However, these diagnoses have been primarily based on clinical presentation and laboratory results of tentative reliability, and the true cause of these illnesses remains unknown.
Four published studies have searched for Borrelia in Australian ticks, with contradicting results. While some Australian ticks have a geographical distribution that matches that of Australian Lyme-like cases, the main ticks that transmit Lyme Borreliosis in the Northern Hemisphere (black-legged ticks) are not found in Australia.
Western Australian researchers have recently described a novel Borrelia species in Australian ticks, which has piqued the interest of the "Lyme disease" community. However, until there is strong evidence from well-performed clinical studies, the existence of Lyme disease in Western Australia remains speculative.

Western Australia researchers found a novel Borrelia species in ticks
Lyme disease is a tick-borne illness caused by the bacterium Borrelia burgdorferi, which is common in the Northern Hemisphere. There is no evidence that classic Lyme disease occurs in Australia, and the Borrelia burgdorferi bacterium has not been found in Australian animals or ticks. However, there have been over 500 reports of an Australian Lyme-like syndrome in the scientific literature, and growing numbers of patients, their supporters, and some politicians are demanding diagnoses and treatment for this illness.
In 2016, researchers from Murdoch University in Perth, Western Australia, published a discovery of a novel species of Borrelia bacteria in ticks on echidnas. This species is related to the relapsing fever group of Borrelia and was identified in 38 out of 97 ticks pulled from echidnas in Queensland and New South Wales, but not in any ticks from Victoria. The discovery has excited Lyme disease activists in Australia, as it suggests that Australian ticks may be responsible for a Lyme-like illness in thousands of Australians. However, it is unknown whether this novel species can be transmitted to humans or cause disease.
The study was prompted by the discovery of a Borrelia species in a single Ixodes holocyclus tick removed from an echidna in the previous year. The researchers investigated the presence of Borrelia in 97 Bothriocroton concolor ticks parasitizing echidnas in Queensland, New South Wales, and Victoria, using nested PCR with Borrelia-specific primers targeting the 16S rRNA (16S) and flaB genes. The Borrelia-specific PCR assays confirmed the presence of a novel Borrelia species related to the relapsing fever and reptile-associated (REP) spirochaetes in 38% of the B. concolor ticks. This novel species was identified in 41% of the ticks in Queensland and New South Wales but was absent in ticks from Victoria.
The discovery of this novel Borrelia species in Australian ticks adds to the growing evidence of a potential Lyme-like disease in Australia. However, further research is needed to determine whether this novel species can cause illness in humans and to fully understand its significance for public health in Australia.

Lyme disease symptoms are similar to neurological disorders
There is no convincing evidence that classic Lyme disease occurs in Australia. However, Lyme disease can be acquired overseas and diagnosed in Australia. In fact, most people presenting with laboratory-confirmed Lyme disease in Australia were infected in Europe.
Lyme disease is caused by the bacterium Borrelia burgdorferi and is transmitted to humans through the bite of an infected tick. Lyme disease can be challenging to diagnose because it can have many nonspecific symptoms that are similar to symptoms of other conditions. Neurological Lyme disease occurs when Lyme disease bacteria invade and affect the nervous system. This can lead to a range of neurological symptoms, including numbness, pain, facial droop, neck pain, vision changes, and more. Neurological symptoms often occur early in the course of Lyme disease, typically 3-5 weeks after the initial bite.
Neurological Lyme disease can resemble and be mistaken for many other conditions, including neurological disorders such as multiple sclerosis (MS). When Lyme disease affects the central nervous system, the symptoms can be very similar to MS, making it difficult for untrained individuals to distinguish between the two. Doctors who are generalists may not be specially trained to diagnose either disease, so it is important for a healthcare professional to make a correct diagnosis.
In addition to MS, Lyme disease has also been associated with other neurological disorders. Some patients initially diagnosed with neurological disorders such as motor neurone disease, Parkinson's disease, and Alzheimer's disease claim that these chronic neurological conditions are caused by Lyme borreliosis.
The diagnosis of neurological Lyme disease typically involves blood tests and physical exams. The Centers for Disease Control and Prevention (CDC) recommends a two-step testing process. The first test checks for Borrelia antibodies in the blood, and if this test is positive, a healthcare professional will perform a Western blot test to confirm the diagnosis.
