Is meningitis (brain fever) a contagious disease?
(02.21.2008)

Yes. Some bacterial meningitis is contagious. Bacteria are usually spread through secretions of the airway and nasopharynx (for example, by coughing and kissing). Fortunately, no other bacteria have as strong an infectivity as influenza (flu) or SARS. Common contact or only inhaling air breathed by meningitis patients cannot lead to infection. But it must be taken seriously, because sometimes close contact or contact over a long period with a meningitis patient can lead to the infection of others.

Influence (flu) is a contagious disease spread mainly through droplets in the air. Its in vitro viability is very weak so the chances of contact by daily articles of use are very small. Diplococcus meningitis usually parasitizes in the mucosa of the nose and pharynx of patients or the disease carriers. When they cough, speak or sneeze, droplets with large amount of germs are sprayed forth and the air becomes contaminated; once healthy people inhale this same air, under the circumstances of immunity and disease resistance decreasing, diplococcus meningitis will invade the blood through the airways, then into the head and cause inflammatory changes, thus resulting in meningitis and a series of clinical symptoms.

The people who work with patients in one room, a nursery or have direct contact via secretions of the mouth (such as kissing) are regarded as being in the susceptible high risk category.
