Meningitis is an infection of the meninges, the protective membranes surrounding the brain and spinal cord. Bacteria, viruses, fungi, and other organisms can cause it. Meningitis symptoms in adults are a serious deal, if left untreated, it can lead to severe complications such as deafness, seizures, and death.
The causes are typically associated with a variety of infections.
Bacterial meningitis is most commonly caused by:
Viral meningitis is usually caused by the following:
Fungal meningitis may result from the following:
Other possible causes include chronic meningitis, Lyme disease, HIV infection, and Syphilis.
Meningitis can be classified according to its duration as acute, subacute, or chronic.
Acute meningitis is the most severe form, usually caused by bacteria or viruses. Acute meningitis symptoms in adults generally include:
The condition may progress rapidly and require immediate medical care.
Subacute meningitis is a more persistent form of the disease which lasts for several weeks or months. It is usually caused by bacterial infections such as tuberculosis or fungal infections such as cryptococcal meningitis. Symptoms are similar to those of acute meningitis but not as severe. Treatment typically involves long-term antibiotics or antifungal medications.
Chronic meningitis is a rare form of the disease which persists for at least three weeks and can be caused by various types of bacteria, fungi, or viruses. Symptoms include:
Treatment involves antibiotics or antifungal medications and supportive care to manage the symptoms.
Meningitis can be life-threatening, so it is essential to seek medical attention if you experience any of the signs and symptoms associated with this condition. Early treatment can help prevent more severe complications.
There is often confusion about which meningitis is contagious. Bacterial and viral meningitis can be contagious, depending on the type of organism causing the infection. In some instances, such as Meningococcal meningitis, it is highly infectious. How meningitis spread? This type of bacterial meningitis is transmitted through the exchange of respiratory secretions or saliva between people in close physical contact. Vaccines are available to help protect against some forms of bacteria that cause meningitis.
Viral meningitis can also be transmitted from person to person, but this is rare. It is typically spread through contact with an infected person's bodily fluids, such as nasal secretions or feces. The virus can also be acquired indirectly by drinking contaminated water or eating improperly cooked food.
Fungal meningitis is not contagious and is usually caused by the inhalation of fungal spores. Individuals can also acquire the condition through contact with soil, bird droppings, or other contaminated materials.
Complications can be severe and long-lasting. Meningitis can cause permanent hearing loss, learning disabilities, or even death if left untreated. Other complications include seizures, cerebral palsy, hydrocephalus, visual impairment, and memory problems.
Treatment depends on the type of meningitis and typically involves antibiotics or antifungal medications for bacterial or fungal infections, respectively. Doctors may treat meningitis caused by Lyme disease with antibiotics such as doxycycline or amoxicillin. In some cases, antiviral drugs may also be needed to treat viral meningitis.
In addition to medication, supportive care may also be necessary to help manage symptoms such as fever and headache. In severe cases, hospitalization may be required for monitoring and to provide additional treatment if needed.
The most effective way to prevent meningitis is by getting vaccinated. Vaccines are available for some bacteria that can cause meningitis, including Meningococcal, Hib, and Pneumococcal.
Other prevention methods include proper hygiene, such as handwashing and avoiding contact with people exposed to the virus or bacteria. These measures include avoiding close contact with ill people and washing your hands frequently with soap and water. It is also important to avoid sharing food, drinks, cigarettes, or other items contaminated with saliva or other bodily fluids. Additionally, taking precautions when traveling where meningitis is common is vital.
