Most people who have Japanese encephalitis have either no symptoms or mild, short-lived symptoms that are flu-like in presentation — mild-to-moderate fever, fatigue, headache and sometimes vomiting. As such, it's very difficult to identify most cases of Japanese encephalitis because it either causes no symptoms or mimics most other mild infections.  It's estimated that less than 1% of people infected with the Japanese encephalitis virus (JEV) develop noticeable symptoms.  In people who do develop symptoms, the incubation period (time from initial infection until signs of illness) is typically between five to 15 days. Although most JEV infections produce mild or no symptoms, about 1 in 250 cases result in severe illness, which often starts with a severe fever. A severe fever is a defense mechanism by your body to slow down or stop the production of invading viruses (or bacteria), but when they get much beyond 103 °F (39.4 °C) in adults or 101 °F (38.3 °C) in children, there is a risk of brain damage. The high fever and increased inflammation in the brain caused by JEV trigger other serious and life-threatening symptoms.  Once significant symptoms develop with Japanese encephalitis, usually in children with weakened immune systems, the chances of dying are about 30%.  Mild cases of Japanese encephalitis can increase your temperature by a couple of degrees, but severe cases spike it by five or more degrees. Like other types of infections that affect the brain and/or spinal cord (such as meningitis), a stiff neck can develop with Japanese encephalitis The neck suddenly feels stiff and is difficult to move in all directions, but it generates especially sharp, shooting or electric-like pain with neck flexion (trying to touch your chin to your chest).  When the spinal cord gets inflamed, the muscles closest to the spine get very tight in efforts to protect it, which is called guarding or splinting. As such, the neck muscles will be hard to the touch and feel like they are spasming. Medication, massage or chiropractic care will not resolve a stiff neck from Japanese encephalitis, meningitis or other infections of the central nervous system. Another effect triggered by brain inflammation and a severe fever is mental changes, such as disorientation, confusion, difficulty focusing and even the inability to speak. Behavioral changes are often interrelated and include irritability and/or poor temper control, as well as wanting to be alone and avoiding social contact.  The more serious symptoms of Japanese encephalitis, once they begin, usually only take a few days or so to become significant and serious. The mental and behavioral changes associated with severe JEV infection can mimic a stroke or Alzheimer's disease. The person will change from a healthy, functioning individual to one with severe mental and physical deterioration. Realizing the signs and symptoms and getting prompt treatment are imperative to improving your chances of survival. Once Japanese encephalitis takes a turn for the worse with increasing swelling and high temperatures, the neurons in the brain start to get damaged and die off. Once this happens, neurological symptoms begin to become obvious, such as uncontrollable shaking of body parts (tremors), muscle weakness or paralysis, difficulty walking and grasping things, and reduced coordination (clumsy looking).  Muscle weakness and paralysis usually starts in the limbs (arms and legs) and progressively spreads around the body, but the face can also be affected initially. Of those who survive a severe bout of Japanese encephalitis (which is about 70% of cases), about 1/4 suffer permanent neurological and/or behavioral problems and disabilities. The progression of a severe bout of Japanese encephalitis invariably ends with seizures, which are triggered by brain swelling, high fever and electrical disruption/discharge in the neurons of the brain. The seizures involve collapse, shaking, muscle spasms, jaw clenching and sometimes vomiting or frothing at the mouth.  Seizures triggered by encephalitis can mimic those of epilepsy but can be far more life-threatening due to brain damage. Children with encephalitis are much more likely than adults to have seizures because their smaller brains are more susceptible to pressure and increased temperatures.  Once seizures begin, becoming unconscious and slipping into a coma is not uncommon.

Article: Though any qualified educators can technically teach IB classes, teachers with an IB background will have a leg up when applying to teach at IB schools. Find a university or educational institution near you offering an IB educator certificate program. You can also sign up for online courses to get a certificate remotely.  Visit the International Baccalaureate website at http://ibo.org/globalassets/professional-development/ib-university-directory-2017-en.pdf to get a listing of the universities offering IB educator certificates, as well as detailed outline of what each specific program entails. On average, IB certification takes about 22 weeks to complete. Each educational institution offering an IB educator program has its own entry requirements. You can look up these requirements on the IB directory, or on your program's website.  To look up the requirements in the IB educator certificates directory go to: http://ibo.org/globalassets/professional-development/ib-university-directory-2017-en.pdf. If you do not meet the requirements, look into the requirements for other certificate programs offered online or in your area. The costs associated with getting an IB educator certificate will depend on the unique fee structure of the institution offering it. This may vary greatly depending on the country the institution is located in. Contact the institution of your choice before applying to get this information. The IB offers 4 keys programmes targeting different ages and educational goals. Choose the aim of your certificate training based on your teaching concentration. For instance:   If you want to teach IB classes in an elementary school, choose the Primary Years programme, geared for children aged 3-12. If your goal is to teach IB classed to middle school students, opt for the Middle Years programme, focusing on children aged 11-16. If your career goal is to teach IB classes to older high school students, choose the Diploma program focusing on academically-focused students aged 16-19. You can also decide to study the Career-related programme, which focuses on more career-specific education for ages 16-19. Whether you take courses in person or online, you will have to pass them all to get your certificate. Some institutions will require a minimum grade for each course, and some will set a time limit on how long you can take to complete all the credits. Find out your school's specific requirements to ensure that you obtain your certificate.
