Meningitis is an inflammation of the fluid and membranes (meninges) surrounding your brain and spinal cord. • The swelling from meningitis typically triggers signs and symptoms such as headache, fever and a stiff neck. • Most cases of meningitis in the United States are caused by a viral infection, but bacterial, parasitic and fungal infections are other causes. Some cases of meningitis improve without treatment in a few weeks. Others can be life-threatening and require emergency antibiotic treatment. • Seek immediate medical care if you suspect that someone has meningitis. Early treatment of bacterial meningitis can prevent serious complications. • Symptoms • Early meningitis symptoms may mimic the flu (influenza). Symptoms may develop over several hours or over a few days. • Possible signs and symptoms in anyone older than the age of 2 include: • Sudden high fever • Stiff neck • Severe headache that seems different from normal • Headache with nausea or vomiting • Confusion or difficulty concentrating • Seizures • Sleepiness or difficulty waking • Sensitivity to light • No appetite or thirst • Skin rash (sometimes, such as in meningococcal meningitis) • When to see a doctor • Seek immediate medical care if you or someone in your family has meningitis signs or symptoms, such as: • Fever • Severe, unrelenting headache • Confusion • Vomiting • Stiff neck • Bacterial meningitis is serious and can be fatal within days without prompt antibiotic treatment. Delayed treatment increases the risk of permanent brain damage or death. • It's also important to talk to your doctor if a family member or someone you live or work with has meningitis. You may need to take medications to prevent getting the infection. • Causes • Meningitis • MeningitisOpen pop-up dialog box • Viral infections are the most common cause of meningitis, followed by bacterial infections and, rarely, fungal and parasitic infections. Because bacterial infections can be life-threatening, identifying the cause is essential. • Bacterial meningitis • Bacteria that enter the bloodstream and travel to the brain and spinal cord cause acute bacterial meningitis. But it can also occur when bacteria directly invade the meninges. This may be caused by an ear or sinus infection, a skull fracture, or — rarely — some surgeries. • Several strains of bacteria can cause acute bacterial meningitis, most commonly: • Streptococcus pneumoniae (pneumococcus). This bacterium is the most common cause of bacterial meningitis in infants, young children and adults in the United States. It more commonly causes pneumonia or ear or sinus infections. A vaccine can help prevent this infection. • Neisseria meningitidis (meningococcus). This bacterium is another leading cause of bacterial meningitis. These bacteria commonly cause an upper respiratory infection but can cause meningococcal meningitis when they enter the bloodstream. This is a highly contagious infection that affects mainly teenagers and young adults. It may cause local epidemics in college dormitories, boarding schools and military bases. A vaccine can help prevent infection. Even if vaccinated, anybody who has been in close contact with a person with meningococcal meningitis should receive an oral antibiotic to prevent the disease. • Haemophilus influenzae (haemophilus). Haemophilus influenzae type b (Hib) bacterium was once the leading cause of bacterial meningitis in children. But new Hib vaccines have greatly reduced the number of cases of this type of meningitis. • Listeria monocytogenes (listeria). These bacteria can be found in unpasteurized cheeses, hot dogs and lunchmeats. Pregnant women, newborns, older adults and people with weakened immune systems are most susceptible. Listeria can cross the placental barrier, and infections in late pregnancy may be fatal to the baby. • l • Fungal meningitis • Fungal meningitis is relatively uncommon in the United States. It may mimic acute bacterial meningitis. It's often contracted by breathing in fungal spores that may be found in soil, decaying wood and bird droppings. Fungal meningitis isn't contagious from person to person. Cryptococcal meningitis is a common fungal form of the disease that affects people with immune deficiencies, such as AIDS. It's life-threatening if not treated with an antifungal medication. Even with treatment, fungal meningitis may recur. • Parasitic meningitis • Parasites can cause a rare type of meningitis called eosinophilic meningitis. Parasitic meningitis can also be caused by a tapeworm infection in the brain (cysticercosis) or cerebral malaria. Amoebic meningitis is a rare type that is sometimes contracted through swimming in fresh water and can quickly become life-threatening. The main parasites that cause meningitis typically infect animals. People are usually infected by eating foods contaminated with these parasites. Parasitic meningitis isn't spread between people. • hashtags.. • #meningitis #medical #animation #video #brain #disease #medical #prevention
