                 A83. 2 Eastern equine encephalitis



Eastern equine encephalitis (Triple E) is an illness caused by a virus that comes from an infected mosquito bite. Most people who are infected have no symptoms, but some may develop fever, headaches, and vomiting. Symptoms occur within 4-10 days of being infected and most recover in 1-2 weeks. A small number will develop swelling of the brain and severe neurological symptoms that can be permanent. Triple E can also lead to coma and death. This condition is caused by a type of arbovirus and is transmitted by a mosquito which has bitten an infected bird or reptile. Diagnosis is based on the symptoms, specific findings in the blood, and occasionally by an MRI of the brain. There is no specific treatment for Triple E. It is managed by taking care of the symptoms. Prevention includes avoiding mosquito bites and controlling mosquito populations.



Symptoms

The following list includes the most common signs and symptoms in people with eastern equine encephalitis (Triple E) virus infections. These features may be different from person to person. Some people may have more symptoms than others and symptoms can range from mild to severe. This list also does not include every symptom or feature that has been described in this condition.

  • Fever
  • Chills
  • Fatigue
  • Vomiting
  • Focal neurological signs
  • Cranial nerve palsies (weakness or loss of function of a large nerve)
  • Coma.

Most people who are infected with the Triple E virus do not get sick. Some develop flu-like symptoms (fever, chills, vomiting) within 4-10 days after being infected. If the infection reaches the brain it can lead to seizures, coma and sometimes, death. Some people may have brain damage that leads to paralysis,  or changes in behavior or personality

Causes

Eastern equine encephalitis (Triple E) is caused by a type of called virus an arbovirus.  Humans catch this virus through a bite from certain types of mosquitos

Treatment

Eastern equine encephalitis (Triple E) is diagnosed in someone who is sick through tests that look for evidence of the triple E virus in blood, tissue or other body fluids.  Sometimes Imaging studies, such as an  MRI or C T scan can be helpful

Eastern equine encephalitis virus (EEE) is transmitted to humans by the bite of an infected mosquito. Eastern equine encephalitis (EEE) is a rare illness in humans, and only a few cases are reported in the United States each year. Most cases occur in the Atlantic and Gulf Coast states. Most persons infected with EEE have no apparent illness. Severe cases of EEE (involving encephalitis, an inflammation of the brain) begin with the sudden onset of headache, high fever, chills, and vomiting. The illness may then progress into disorientation, seizures, or coma. EEE is one of the most severe mosquito-transmitted diseases in the United States with approximately 33% mortality and significant brain damage in most survivors. There is no specific treatment for EEE; care is based on symptoms. You can reduce your risk of being infected with EEE by using insect repellent, wearing protective clothing, and staying indoors while mosquitoes are most active. If you think you or a family member may have EEE, it is important to consult your healthcare provider for proper diagnosis.

                     A40.   9   Streptococcal sepsis, unspecified Sepsis is a potentially life-threatening condition that occurs when the body's response to an infection damages its own tissues. When the infection-fighting processes turn on the body, they cause organs to function poorly and abnormally. Sepsis may progress to septic shock. This is a dramatic drop in blood pressure that can lead to severe organ problems and death. Early treatment with antibiotics and intravenous fluids improves chances for survival. Causes While any type of infection — bacterial, viral or fungal — can lead to sepsis, infections that more commonly result in sepsis include infections of: Lungs, such as pneumonia Kidney, bladder and other parts of the urinary system Digestive system Bloodstream (bacteremia) Catheter sites Wounds or burns Risk factors Several factors increase the risk of sepsis, including: Older age Infancy Compromised immune sy...

M12.10 Kaschin-beck disease unspecified site   Kashin-Beck disease  (KBD) is an endemic chronic osteochondral disease, which has a high prevalence and morbidity in the Eastern Siberia of Russia, and in the broad diagonal, northern-east to southern-west belt in China and North Korea. In 1990's, it was estimated that in China 1–3 million people had some degree of symptoms of the disease, although even higher estimates have been presented. In China, the extensive prevalence peaked in the late 1950's, but since then, in contrast to the global trend of the  osteoarthritis  (OA), the number of cases has been dramatically falling. Up to 2013, there are 0.64 millions patients with the KBD and 1.16 millions at risk in 377 counties of 13 provinces or autonomous regions. This is obviously thanks to the preventive efforts carried out, which include providing millions of people with dietary supplements and clean water, as well as relocation of whole villages in China. However, re...

                        A28.9 Zoonotic bacterial diseases unspecified Most humans are in contact with animals in a way or another. A zoonotic dise   ase is a disease or infection that can be transmitted naturally from vertebrate animals to humans or from humans to vertebrate animals. More than 60% of human pathogens are zoonotic in origin. This includes a wide variety of bacteria, viruses, fungi, protozoa, parasites, and other pathogens. Factors such as climate change, urbanization, animal migration and trade, travel and tourism, vector biology, anthropogenic factors, and natural factors have greatly influenced the emergence, re-emergence, distribution, and patterns of zoonoses. As time goes on, there are more emerging and re-emerging zoonotic diseases. In this review, we reviewed the etiology of major zoonotic diseases, their impact on human health, and control measures for better management. We also highlighted COVID-19,...
