Encephalitis
Pathogen/Cause: What causes the disease (virus, bacteria, fungus, protist, …)?
Encephalitis is a viral infection that has multiple different causes. Encephalitis can be caused by the herpes simplex virus, and although this is rare, this type of encephalitis can cause severe brain damage or even death. Encephalitis can also be caused by animals. If a person were to come into contact with an infected animal (an animal with rabies), or be bitten by one, then the person can contract encephalitis. There is also tick-borne encephalitis and Japanese encephalitis (which are classified under Arboviruses). Tick-borne encephalitis is more common in European countries, and this kind of encephalitis is caused by Lyme disease. Japanese encephalitis is spread by mosquitoes, and is common in Asia. The people who contract this kind of encephalitis are most commonly found on farms.

Primary encephalitis happens when the virus directly infects the brain. This could be caused by a reactivation of a previously inactive virus. Secondary encephalitis is caused by a dysfunctional immune system. This happens when there is another virus in the body, but instead of targeting the virus, the immune system attacks the brain instead. Secondary encephalitis will happen two to three weeks after first contracting the virus. The virus can be diagnosed using a variety of methods. For more mild cases of encephalitis, only physical examinations and/or blood tests are required. However, if a more severe case is suspected, then there are several tests that can be performed. A doctor can perform; a CT (computed tomography) scan, an EEG (Electroencephalography) scan (used to measure brain waves), a spinal tap, or an MRI (magnetic resonance

    Equine Encephalomyelitis, or Equine Encephalitis, is extremely deadly and rare to all equine species, and almost all cases result in death. Equine Encephalitis is an arbovirus, meaning that it is transmitted by mosquitoes, ticks and other insects (Fraser 599). A few symptoms consist of excitable behavior, walking into secured objects, and becoming drowsy (Fraser 600 and Menu and Pavord; pavord). In order to treat Equine Encephalitis you must vaccinate your horse before he/…

    Brazil, there has been a recent outbreak of cases where infants are found to be born with microcephaly. Scientist is building a case whether or not the Zika Virus is the leading cause of why infants are born with microcephaly. Microcephaly is a condition where the head circumference is smaller than normal size and can be caused by genetic mutations from use of drugs and alcohol or from certain virus and toxins that the fetus is exposed to and leads to damaging the developing brain tissue. A airborne virus is currently spreading through the Americas. It is carried by the stealth virus, most often borne on the wings of a ubiquitous predator, is spreading across the Americas.…

    You can even infect another human through air droplets while talking. The sprinkle of droplets when you cough and sneeze can widely spread any infectious disease. For a long time, these infectious agents can travel far distances and remain up in the air. Other bad organisms can also stay on objects (fomite). You might be exposed to bad infection, if you touch a light switch, soon after an infected human has touched it.…

    Acute disseminated encephalomyelitis is a very rare disease that effects only about 0.2 to 0.7 per 100,000 children per year (Kuni, B., Banwell, B., & Till, C. 2012). Commonly misdiagnosed for multiple sclerosis, acute disseminated encephalomyelitis can be fatal to one’s health if not diagnosed in adequate time. Because of this fact, it is important to educate the general public about the symptoms and outcomes of individuals diagnosed with acute disseminated encephalomyelitis. This paper will provide evidence to answer the question: what are the cognitive and biological symptoms and outcomes to individuals diagnosed with acute disseminated encephalomyelitis.

It is the reaction of the body's immune system to infection or invasion, and is often caused by a viral infection or a reaction to a virus or foreign protein. The viruses that cause primary, or viral encephalitis can be epidemic, like Polio, or sporadic, including herpes simplex virus, type 1 (HSV-1), and mumps. It is caused by direct viral infection, whilst secondary encephalitis is caused by an immune reaction to viral infection somewhere else in the…
