Encephalitis, tick-borne, inactivated, whole virus is a vaccine used to prevent tick-borne encephalitis (TBE), a viral infection of the brain caused by the bite of an infected tick. The vaccine is made from inactivated (killed) whole virus particles, which are injected into the body to stimulate the production of protective antibodies against the virus. The vaccine is most effective when given in two doses, 3-6 months apart. Side effects are usually mild and may include redness, swelling, and pain at the injection site, as well as fever and headache.
Encephalitis, tick-borne (TBE) is a viral infection that inflames the brain and spinal cord. It's a serious condition transmitted by ticks. Here's a breakdown of the key points about TBE:
Cause: TBE is caused by tick-borne encephalitis virus (TBEV), which has several subtypes. Different subtypes are found in Europe, Asia, and parts of Russia.
Transmission: TBE is primarily transmitted through the bite of an infected tick. Ticks acquire the virus by feeding on infected animals like rodents or deer. Transmission can also occur, in rare cases, through consuming unpasteurized dairy products from infected animals or through organ transplantation.
Symptoms: TBE can cause a range of symptoms, and the severity can vary. In some cases, there may be no symptoms at all (especially in children). Here's a general progression:
- Initial stage (2-7 days after tick bite): Flu-like symptoms like fever, headache, muscle aches, fatigue, nausea, and vomiting are common.
- Second stage (after a brief period of improvement): In some cases, the virus infects the brain and spinal cord, leading to more severe symptoms like severe headache, confusion, disorientation, seizures, and weakness or paralysis in limbs.
Diagnosis: Diagnosis of TBE involves a combination of factors, including the person's symptoms, travel history, and potential tick exposure. Blood tests can detect the virus or antibodies against it.
Treatment: There is no specific antiviral medication for TBE. Treatment focuses on supportive care to manage symptoms, such as pain relievers, fever reducers, and medications to control inflammation. In severe cases, hospitalization and intensive care may be needed.
Prevention:
- Vaccination: The most effective way to prevent TBE is vaccination, which is recommended for people who live in or travel to areas where the virus is found.
- Tick avoidance: Measures to prevent tick bites are also crucial. This includes using insect repellents containing DEET, wearing long clothing and tucking pants into socks when venturing into tick-infested areas, and performing daily tick checks.
