What is encephalitis eastern horses?

encephalitis Eastern horses (EEE) is a rare viral disease transmitted by the bite of an infected mosquito. In most cases there are no symptoms. Severe EEE cases can lead to encephalitis, brain inflammation that is most common. People aged 15 and 50 are the most susceptible.

Encephalitis of eastern horses is carried by Member, Arbovirus, illness, which means that in this case a mosquito is a contractual arthropod by rushing blood. The virus usually comes from a mosquito cycle, which includes mosquito types culiset melanura . The virus sometimes spreads to horses and people through Coquillettidia perbans or more common types of aedes canadensis .

Eastern horse encephalitis is divided into two variants, northern and South American. Eee is most common in these countries east of the Mississippi River, especially in areas nearby or containing large supply of freshwater water, swamps and marshes surrounded by wooded areas.Outside the US, Eastern horse encephalitis was also found in the coastal areas of the Gulf. Mosquitoes who transmit the virus from birds usually die in the winter months and limit the extent of infections to the autumn and summer season.

The spread of encephalitis Eastern horses is dependent on arthropods and is therefore very limited to geographical extent. No substantial amount of virus is transmitted after infection. As a result, it is very unlikely that another mosquito could close the disease from a horse or a person who has been infected.

The first symptoms of eastern horses are high fever, usually 103 ° F to 106 ° F (39.5 ° C to 41.11 ° C), headache, nausea and diarrhea, each of which occurs five to ten days after infection, but not always at the same time. The lack of specific early symptoms makes it difficult to diagnose EEE. The disease progresses rapidly to the disfunction and death of the central nervous system.

mostThe more serious and serious development that occurs as a result of EEE is the advent of encephalitis. The first symptoms of this do not differ much from the first symptoms and manifest themselves as headaches, fever, confusion, drowsiness and fatigue. As encephalitis progresses, symptoms can be expanded to include seizures, about 50% infected and tremor, hallucinations, photophobia and memory problems.

There is no known medicine or treatment of east horses encephalitis. The mortality rate is estimated to be 30%-70%. Morbidity is around 90%, with most survivors are permanently affected. Only 10% of the infected recover completely. Since 1964, only 163 have been confirmed by EEE cases, with most years of less than five cases.

diseases can be prevented. To ensure the total is fully dressed and the use of repellent insects is the most famous preventive measure. One should also remain in the interior between dusk and dawn hours when mosquitoes are most active in the summer months.
