Did you know these Facts about Tick-borne Encephalitis?


Tick-borne encephalitis or TBE is a viral infectious disease affecting the central nervous system. It is caused by the TBEV or Tick-borne encephalitis virus (TBEV). It was originally isolated in 1937. There are three virus subtypes. They are -

●     European or Western tick-borne encephalitis virus
●     Siberian tick-borne encephalitis virus
●     Far eastern Tick-borne encephalitis virus

What is tick-borne encephalitis (TBE)?
Tick-borne encephalitis (TBE) is a severe disease caused by a virus spread through the tick bites. You can also get TBE by eating or drinking unpasteurized dairy products like milk and cheese from infected cows, sheep, or goats.

What are the symptoms of TBE?
The symptoms of TBE include,
●     Fever
●     Achiness
●     Loss of appetite
●     A headache
●     Nausea
●     Vomiting

In 20-30% patients infected with TBE suffer from swelling of the brain and spinal cord, sensory disturbances and confusion. Around 1% people die from TBE.

Who is at risk?
TBE is found in many parts of Asia and Europe (from eastern France to northern Japan and from north Russia to Albania). Thousands of cases are reported every year, but there are plausibly many other cases which do not get reported. The highest number of TBE cases occurs in Russia. Other countries with high risk for TBE disease are Estonia, Czech Republic, Latvia, Germany, Hungary, Lithuania, Poland, Switzerland, Slovenia, Sweden, Japan, China, South Korea and Mongolia. Travellers are more likely to get TBE in mostly in early and late summer from April through November. If you are travelling through the forested areas where ticks are prevalent, the chances of getting TBE are high.

Signs and Symptoms
●     The incubation period of Tick-borne encephalitis is usually between 7-14 days and is asymptomatic.
●     In contrast to the far-eastern TBE, European TBE is more critical in adults than in children where meningitis is more commonly observed.
●     In approximately two-thirds of individuals infected with the European TBE virus, only an early (viremic) phase is endured. Its symptoms are nonspecific and may involve malaise, fever, muscle aches, anorexia, nausea, headache, and vomiting.
●     After about 8-9 days of remission, the second stage of disease occurs in 20 - 30% of patients. Such patients might experience an illness which involves the central nervous system with symptoms of meningitis, meningoencephalitis or encephalitis.
●     The recovery period can be prolonged, and the incidence of sequelae may vary with long-term or the permanent neurologic symptoms.

Treatment
There is no precise drug therapy for TBE. Meningitis, encephalitis, or meningoencephalitis needs immediate hospitalisation and better medical care based on the severity of the symptoms. Anti-inflammatory drugs, like as corticosteroids, may be considered under special circumstances for symptomatic relief. You should consult with your doctor and get the necessary medicines from any travel health clinic Northampton. Early diagnosis and good medical care can help to counter the TBE.

Are you searching for a lasting solution to your facial wrinkles? then you're on the right article. Research has it that there are processes that facilitate wrinkle formation, thereby contributing to making us have a much older appearance and they include:  our everyday facial expression and loss of skin elasticity. Loss of skin elasticity happens alongside the loss of volume and it gives the long-term effect of sagging; it gives the feel of loose muscles, making them lack the firmness they normally should have.  Also, our everyday facial expressions refer to how we use our facial muscles. There are typical facial wrinkles with negative connotations and they are frown lines or furrows between the eyes which makes us look like we are intensely worried or negative. Dealing with wrinkles should not be so much of a problem because there are now medically acceptable ways to deal with it, they are called anti-wrinkle treatment. Anti-wrinkle treatments are available in dif...

What are the symptoms of Japanese Encephalitis?

Japanese Encephalitis is inflammation in the brain caused by a virus called Japanese encephalitis virus (JEV). South Asia is the common grounds to get this disease. The virus is spread from the bite of the infected mosquito. The virus enters the mosquitoes from pigs and birds. Fortunately is not contagious from human to human. Agricultural fields and rural areas are common places where this disease is seen. 90% of the patients are asymptomatic in the first phase. Flu and diarrhoea are seen in the first two days. Headaches, vomiting, raised tones, intracranial pressures increase and seizures are seen in phase 2.  Clinical findings are used to diagnose Japanese Encephalitis.  Lymphocytosis is seen in the blood. Lumbar puncture is done to examine the cerebrospinal fluid. This disease has no cure. Therefore one can only rely on the available vaccine for prevention of the Japanese Encephalitis. Only the symptoms are treated by admitting the patient to a hospital and administe...
