Meningitis is caused when the protective membranes surrounding a person’s spinal cord and brain become inflamed. It can be caused by both viruses and bacteria. It is important to know what caused a case of meningitis because it impacts how severe the illness may be and its treatment. Cases caused by a virus are generally less severe and resolve without specific treatment, while cases caused by bacteria can be quite severe; may result in brain damage, hearing loss, or learning disability; and may be treatable with antibiotics.

Vaccines are available for meningococcal meningitis. For more information please visit: http://www.cdc.gov/meningococcal/vaccine-info.html
The Wyoming Department of Health only tracks cases of S. pneumoniae that are considered invasive – this means that the bacteria was isolated from a sterile fluid in a person’s body (i.e. blood, joint fluid, etc.). Invasive cases of S. pneumoniae are also known as Invasive Pneumococcal Disease (IPD). It is important to note that not every case of IPD results in meningitis. Between 2005 and 2015, there were 292 reported cases of IPD in Wyoming, and of these 21 had meningitis (7%).
A vaccine is available for IPD. For more information, please visit: http://www.cdc.gov/vaccines/vpd-vac/pneumo/.
