Tick-Borne Encephalitis Vaccination Oxford

Frequently Asked Questions

What is Tick-borne encephalitis?

Tick-borne encephalitis (TBE) is a viral disease caused by the tick-borne encephalitis virus (TBEV). It is primarily transmitted to humans through the bite of infected ticks. TBE can lead to inflammation of the brain (encephalitis) and can result in a range of symptoms including fever, headache, muscle aches, and neurological complications. The disease is prevalent in certain regions of Europe and Asia, particularly in forested areas where ticks are abundant. Vaccination is available to protect against TBE for individuals at risk of exposure.

How can you contract Tick-borne encephalitis?

Tick-borne encephalitis (TBE) is contracted through the bite of infected ticks. When a person is bitten by a tick carrying the tick-borne encephalitis virus (TBEV), the virus can enter their bloodstream and cause infection. Ticks become infected with TBEV by feeding on infected animals, such as small mammals or birds, which serve as reservoir hosts for the virus.

Ticks are most active in wooded and grassy areas, particularly during the spring and summer months. Humans can contract TBE by spending time outdoors in areas where infected ticks are present, such as forests, fields, or meadows. It's important to note that not all tick species carry TBEV, and the risk of contracting the virus varies depending on the geographical location.

Preventing tick bites is crucial in reducing the risk of contracting tick-borne encephalitis. This can be done by taking precautions such as wearing protective clothing (long sleeves, long pants), using insect repellents containing DEET on exposed skin, avoiding tick-infested areas whenever possible, and conducting thorough tick checks after spending time outdoors. Vaccination against tick-borne encephalitis is also available in some regions for individuals at risk of exposure. 

Symptoms of Tick-borne encephalitis

The symptoms of tick-borne encephalitis (TBE) can vary depending on the individual and the severity of the infection. In some cases, TBE infection may not cause any noticeable symptoms. However, when symptoms do occur, they typically manifest in two phases:

Initial phase: After an incubation period of 7 to 14 days, the initial phase of TBE may involve flu-like symptoms such as fever, headache, fatigue, muscle aches, and nausea. Some individuals may also experience a rash at the site of the tick bite.

Neurological phase: In more severe cases, the infection can progress to the neurological phase. This phase is characterised by symptoms such as high fever, severe headaches, neck stiffness, confusion, tremors, muscle weakness, and in some cases, paralysis. Neurological symptoms can vary in severity and may lead to long-term complications or even death.

It's important to note that not all individuals infected with tick-borne encephalitis will develop neurological symptoms. Some may experience a milder form of the disease with flu-like symptoms that resolve on their own. However, for those who do develop neurological symptoms, medical attention should be sought immediately as TBE can be a serious and potentially life-threatening condition.

How is Tick-borne encephalitis treated?

There is no specific antiviral treatment for tick-borne encephalitis (TBE). The treatment primarily focuses on managing the symptoms and providing supportive care. This may include:

• Hospitalisation: Severe cases of TBE may require hospitalisation for close monitoring and supportive treatment.

• Symptom management: Medications can be prescribed to relieve fever, pain, and other symptoms. Bed rest, proper hydration, and a balanced diet are also important.

• Supportive care: In cases where there are neurological complications or symptoms, additional care may be needed. This can involve measures such as physical therapy, speech therapy, or occupational therapy to help manage and improve any resulting movement or cognitive issues.
   

Prevention is key when it comes to tick-borne encephalitis. Vaccination is available in some regions where TBE is prevalent and is recommended for individuals at risk of exposure. It's important to take precautions to avoid tick bites, such as using insect repellents, wearing protective clothing, and performing regular tick checks after spending time in areas where ticks are prevalent.

How to prevent Tick-borne encephalitis?

To prevent tick-borne encephalitis (TBE), you can take the following measures:

​

1. Vaccination: In regions where TBE is prevalent, getting vaccinated is the most effective way to prevent the disease. Consult with your healthcare provider or travel clinic to check if TBE vaccination is recommended for your specific situation.
    

2. Avoid tick-infested areas: If you are in an area where ticks are common, try to avoid tall grasses, shrubs, and wooded areas where ticks are more likely to be present. Stick to well-maintained paths and trails.
    

3. Wear protective clothing: When visiting tick-prone areas, wear long-sleeved shirts, long pants, and closed-toe shoes. Tuck your pants into your socks or boots to prevent ticks from crawling up your legs. Light-coloured clothing can make it easier to spot ticks.
    

4. Use insect repellents: Apply an approved insect repellent on exposed skin and clothing. Look for repellents containing DEET. Follow the instructions on the product label and reapply as needed.
    

5. Perform tick checks: After spending time in areas where ticks are present, thoroughly check your body, clothing, and gear for ticks. Pay close attention to areas such as the scalp, behind the ears, armpits, groin, and behind the knees. Promptly remove any attached ticks using tweezers.
    

6. Remove ticks properly: If you find an attached tick, use fine-tipped tweezers to grasp it as close to the skin's surface as possible. Gently and steadily pull the tick upward without twisting or jerking. Clean the bite area with antiseptic.
    

7. Protect pets and livestock: Apply tick preventive treatments to your pets, and regularly check them for ticks. If you live in a tick-endemic area, consider talking to a veterinarian about tick control measures for your pets.
    

Remember to consult with healthcare professionals or local health authorities for specific prevention recommendations based on your geographical location and risk factors.
