This resulted in 236,000 deaths, down from 433,000 deaths in 1990. With appropriate treatment, the risk of death in bacterial meningitis is less than 15%. Outbreaks of bacterial meningitis occur between December and June each year in an area of sub-Saharan Africa known as the meningitis belt. Smaller outbreaks may also occur in other areas of the world. The word meningitis comes from the Greek μῆνιγξ meninx, "membrane", and the medical suffix -itis, "inflammation". Signs and symptoms
Clinical features
In adults, the most common symptom of meningitis is a severe headache, occurring in almost 90% of cases of bacterial meningitis, followed by neck stiffness (the inability to flex the neck forward passively due to increased neck muscle tone and stiffness). The classic triad of diagnostic signs consists of neck stiffness, sudden high fever, and altered mental status; however, all three features are present in only 44–46% of bacterial meningitis cases. If none of the three signs are present, acute meningitis is extremely unlikely. Other signs commonly associated with meningitis include photophobia (intolerance to bright light) and phonophobia (intolerance to loud noises). Small children often do not exhibit the aforementioned symptoms, and may only be irritable and look unwell. The fontanelle (the soft spot on the top of a babys head) can bulge in infants aged up to 6 months. Other features that distinguish meningitis from less severe illnesses in young children are leg pain, cold extremities, and an abnormal skin color.Nuchal rigidity occurs in 70% of bacterial meningitis in adults.
Its eye was in the center of the forehead and there was no developed nose to be found. The small cat died shortly after it was born. It was nicknamed Cleyed the Cyclops. On May 10, 2017, in Assam, India, a black goat was born with one eye and other cyclopia-related facial abnormalities. It was reported to still be alive over a week later, which is unusual for this condition. On September 13, 2018, in Mandailing Natal, North Sumatera, Indonesia, a baby with cyclopia was born without a nose and one eye with the weight of 2.4 kg (5.3 lb) and heart rate under 100 bpm. The child died seven hours after birth. Cultural significance
The Islamic State of Iraq and the Levant used photos of babies born with cyclopia in its recruitment campaign. ISIL claimed the photos depicted Masih ad-Dajjal, who according to the Hadith, would have only one eye. Mainstream Islamic scholars consider the prophecy as referring to a one-eyed man, not a cyclops. See also
