Acute inflammation of the brain envelopes or meningitis can develop due to a variety of reasons. Depending on them, the disease is differentiated into primary and secondary.
Causes of primary meningitis
The main cause of primary meningitis is infection with meningococci or viruses. The group of potentially dangerous microorganisms includes:
- streptococci;
- staphylococci;
- pneumococci ;
- Occasionally, pathology is provoked by the penetration of enteroviruses, herpes viruses, group B hepatitis.
Infection occurs as a result of a decrease in the immune barrier. To penetrate the body pathogenic cultures can due to injury, infection by airborne or by domestic route. Some types of bacteria are transferred during sexual intercourse, and are also transmitted from mother to child during childbirth.
However, this does not mean that the carrier of a microorganism necessarily falls ill with meningitis. First of all, the reason for the appearance of meningitis lies in the inability of the body to provide a worthy repulse to the invaders. In this case, getting the infection into the body leads to the transfer of microorganisms by lymph and blood.
Causes of secondary meningitis
The disease can manifest as a complication of another pathology. For example, as a result of facial or cervical furunculosis or pneumonia, pathogenic bacteria are able to penetrate the membranes of the brain. Most often, the first signs of secondary meningitis are manifested due to:
- osteomyelitis of the bones of the skull;
- sinusitis;
- furunculosis ;
- measles;
- chicken pox;
- rubella;
- otitis media;
- frontitis;
- sinusitis;
- abscess of the lung.
Therefore, it is worth taking a closer look at health and not neglecting treatment. Remember that almost any pathology of a viral or bacterial nature can lead to serious complications, including, to meningitis.
