Overview
Meningitis is the inflammation of the membranes that outline yourbrain and spinal cord. These membranes are calledmeninges, giving the illness its name: “meningitis.” Meningitis can be bacterial or viral, though there are also fungal forms of the disease. Viral meningitis is the most common form. Bacterial meningitis is the most serious form. Without treatment, bacterial meningitis can causeparalysis,stroke,seizures,sepsis, and even death.
The hallmark symptoms of bacterial meningitis are:
If you develop the disease, you may also experience:
- nausea
- vomiting
- sensitivity to bright light
- confusion
- arashof purple discoloration
Parents of babies and toddlers under the age of 2 should closely monitor any lingering irritability or lack of interest in eating, as these can also be symptoms of meningitis.
Symptoms can begin quickly, sometimes in just a couple hours, or they can progress over a day or two. Seek immediate medical attention if you show symptoms of bacterial meningitis. Your doctor will treat the condition as soon as possible, most likely withantibiotics.
Bacterial meningitis is caused by several different types of bacteria, including:
- Streptococcus pneumoniae, also called pneumococcus
- Neisseria meningitidis, also called meningococcus
- Haemophilus influenzae, also called Hib
- Listeria monocytogenes
- group B strep
- E. coli
细菌引起脑膜炎可以生活在你的老板dy and the environment around you. In many cases they are harmless. Bacterial meningitis occurs when these bacteria get in your bloodstream and travel to your brain and spinal cord to start an infection.
Most bacteria that cause this form of infection are spread through close personal contact, such as:
An infected person’s throat secretions, like phlegm and saliva, contain bacteria. When that person coughs or sneezes the bacteria travel through the air. But most of the germs that can lead to bacterial meningitis aren’t contagious. In fact, the bacteria that cause meningitis are less contagious than viruses that cause the cold or flu.
Not all bacteria that cause meningitis are spread from one person to another. You can also develop bacterial meningitis after eating certain foods containing theListeriabacterium, such as:
- soft cheeses
- hot dogs
- sandwich meats
Problems due toListeriaare more common in:
- pregnant women
- the elderly
- babies
Meningitis-causing bacteria are more likely to attack the membranes of your brain after a trauma such as:
- ahead fracture
- surgery
- asinus infection
These conditions lower your immunity and disrupt your body’s natural barriers, leaving your body open to infection of any kind, including bacterial meningitis.
Additionally, babies and people with weak immune systems are more likely to develop bacterial meningitis. It’s important to note that the cause of an infection can be hard to pinpoint.
Some types of bacterial meningitis can be prevented throughimmunizations. There are vaccines that protect against pneumococcus, meningococcus, and Hib, all of which cause meningitis. Vaccinations are key to the prevention of meningitis. See your doctor to make sure your vaccinations, and those of your children, are up-to-date.
Bacterial meningitis can lead to severe health complications, such as stroke andbrain damage. It can even be fatal. Complications of the disease are often permanent. Other serious possible complications include:
- memory problems
- hearing loss
- paralysis
- kidney failure
- body-wide infection and shock, calledsepticemia
- movement problems, such as difficulty walking
- learning disabilities
- headaches
- seizures
如果你正在经历的症状s of bacterial meningitis, seek medical care immediately. The disease can usually be treated with antibiotics. If meningitis is caught early enough a patient can make a full recovery with few or no lingering effects. But the best way to combat meningitis is to prevent it through vaccination and sound health practices. Understanding the causes of meningitis and how it spreads will help you stay healthy and keep you from experiencing this dangerous disease.
