# Eastern Equine Encephalitis: A Deadly Mosquito-Borne Disease ## What is Eastern Equine Encephalitis (EEE)? Eastern Equine Encephalitis (EEE) is a rare but deadly mosquito-borne disease that affects the brain. It is caused by the EEE virus, which is transmitted to humans through the bite of an infected mosquito. EEE is most commonly found in the eastern United States, but cases have been reported in other parts of the country as well. ## Symptoms of EEE The symptoms of EEE can vary depending on the severity of the infection. Mild cases may cause only a fever and headache, while more severe cases can lead to seizures, coma, and even death. The most common symptoms of EEE include: * Fever * Headache * Chills * Weakness * Muscle aches * Nausea * Vomiting * Confusion * Seizures * Coma ## Diagnosis of EEE EEE is diagnosed based on the patient's symptoms and a blood test that can detect the EEE virus. A spinal tap may also be performed to rule out other causes of the patient's symptoms. ## Treatment of EEE There is no specific treatment for EEE, but supportive care can help to improve the patient's chances of survival. Treatment may include: * Intravenous fluids * Electrolytes * Antibiotics (if a bacterial infection is present) * Antiviral medications * Respiratory support * Seizure medications ## Prevention of EEE The best way to prevent EEE is to avoid mosquito bites. This can be done by: * Using insect repellent * Wearing long sleeves and pants when outdoors * Staying indoors at dawn and dusk when mosquitoes are most active * Eliminating standing water around your home, where mosquitoes can breed ## Outlook for EEE The outlook for EEE depends on the severity of the infection. Mild cases may resolve on their own within a few weeks, while more severe cases can be fatal. The overall mortality rate for EEE is about 30%. ## Resources * [Centers for Disease Control and Prevention: Eastern Equine Encephalitis (EEE)](https://www.cdc.gov/easternequineencephalitis/index.html) * [National Institutes of Health: Eastern Equine Encephalitis](https://www.nichd.nih.gov/health/topics/encephalitis/conditioninfo/Pages/default.aspx) * [Mayo Clinic: Eastern Equine Encephalitis](https://www.mayoclinic.org/diseases-conditions/eastern-equine-encephalitis/symptoms-causes/syc-20353140)
