- CSIRO, University of Sydney, ANU, and University of Melbourne are actively studying tick-related diseases
Ticks are more than just a nuisance – they can pose serious health risks. While most tick bites are harmless, some can lead to allergic reactions and disease. Research is uncovering the connections between ticks and human health. In this article, we’ll explore common tick-borne illnesses in Australia, and the exciting developments being made in the world of science.
Tick-Related Illnesses in Australia
The good news is that tick-borne diseases are less common in Australia than other parts of the world. However, there are diseases linked to tick bites in Australia, mostly caused by the paralysis tick – It’s the most common culprit for tick-related health issues. So, what are the most concerning tick-related illnesses in Australia?
- Allergic Reactions & Anaphylaxis – Tick saliva contains proteins that can trigger severe allergic reactions, leading to anaphylaxis
- Mammalian Meat Allergy (Alpha-Gal Syndrome) – This emerging condition is triggered by tick bites, causing an allergy to red meat
- DSCATT (Debilitating Symptom Complex Attributed to Ticks) – A condition characterised by chronic fatigue, pain, and neurological symptoms, though its exact cause remains unclear
- Candidatus Neoehrlichia australis Infection – A newly identified bacterial infection in Australia that affects the immune system
- Tick Paralysis – Caused by Ixodes holocyclus, this condition results from a neurotoxin that can cause paralysis, particularly in pets and children
Factors That Increase Your Risk of Disease Transmission
While prevention is key, ticks can still find a way to bite despite our best efforts. But don’t worry – there are steps you can take to lower your risk of potential illness! So, familiarise yourself with the factors that influence the likelihood of tick-related disease transmission:
- Tick Removal Method – Incorrect removal (e.g., squeezing the tick) can increase the risk of toxin or allergen release
- Tick Species – Some ticks carry more potent toxins or bacteria than others
- Location of the Bite – Bites near the head and neck may cause stronger reactions
- Underlying Health Conditions – People with immune system disorders may be more susceptible to tick-related illnesses
- Duration of Attachment – The longer a tick remains attached, the greater the potential for toxin exposure
Breakthroughs in Tick-Related Disease Research
Exciting advancements are being made in Australia’s research. Scientists are uncovering new insights into tick-borne illnesses, leading to more effective treatments and prevention measures. With innovative breakthroughs on the horizon, there’s growing hope for better health management. Scientists are currently exploring:
- The role of tick saliva proteins in allergic reactions
- New potential pathogens in Australian ticks
- Effective tick bite prevention methods, including repellents and vaccines
- The genetic factors that may predispose individuals to tick-related conditions
Leading research institutions are actively exploring tick-related illnesses, driving progress and innovation in the fight against diseases. These include:
- CSIRO – Leading research into DSCATT and tick-borne immune reactions
- University of Sydney – Investigating tick paralysis and allergic reactions
- Australian National University (ANU) – Studying potential tick-borne bacterial infections
- University of Melbourne – Examining tick saliva proteins and their effects on human health
Now, let’s explore 3 common and emerging tick-related diseases in Australia
1. Alpha-Gal Syndrome
Alpha-gal syndrome (AGS) is an allergic reaction to mammalian meat, triggered by tick bites. The paralysis tick has been linked to this condition in Australia. Symptoms range from mild hives to severe anaphylaxis and typically occur hours after consuming red meat. Avoiding tick bites and red meat is the primary management strategy.
2. DSCATT (Debilitating Symptom Complex Attributed to Ticks)
DSCATT is not fully understood in Australia, but it is linked to tick bites. Symptoms include persistent fatigue, muscle pain, headaches, and cognitive issues. Unlike Lyme disease (which is not present in Australia), DSCATT currently lacks a known bacterial cause.
The CSIRO has been conducting research into DSCATT to determine its causes and affects. Studies suggest that while DSCATT is linked to tick bites, it may result from immune system reactions rather than an infectious agent. Ongoing studies aim to clarify its mechanisms and to better understand its origins and impact.
3. A Bug with a Big Name: Candidatus Neoehrlichia australis
Candidatus Neoehrlichia australis is a recently identified bacterial infection in Australia. It belongs to the Ehrlichia family, known to infect white blood cells. Symptoms include fever, fatigue, and immune system suppression. This infection is rare and can be serious for immunocompromised people. More research is needed to determine its prevalence and transmission patterns.
FAQs
Q1: Can ticks in Australia transmit Lyme disease?
No, there is no scientific evidence that Australian ticks carry Lyme disease-causing bacteria.
Q2: What should I do if I am bitten by a tick?
Use fine-tipped tweezers to carefully remove the tick without squeezing it. Do not apply chemicals or irritants.
Q3: Are tick-borne diseases common in Australia?
No, but allergic reactions and conditions like DSCATT and Alpha-Gal Syndrome are increasingly recognised.
Q4: Can ticks cause paralysis in humans?
Yes, ticks can cause paralysis in humans, but it more commonly affects pets.
