Haemophilus influenzae, neisseria meningitidis

Meningitis

What is meningitis? Meningitis is an inflammation of the membranes covering the brain and spinal cord


. This may be caused by a number of infectious agents, including


viruses and bacteria. The type of meningitis and its cause can only be determined by your doctor


using the results of laboratory tests. Viral meningitis (also called aseptic meningitis) is the most common type


meningitis and less serious than bacterial meningitis. In Illinois


on average 600 cases of aseptic meningitis annually, with most


occur in late summer and early autumn. In most cases of aseptic meningitis caused by viruses


called enteroviruses that can infect >> << stomach and small intestine. A small number of cases caused by different viruses


which can be transferred to an infected mosquito, called arbovirusov. Fatal cases of viral meningitis are rare and complete recovery is the rule. Bacterial meningitis is often heavier than aseptic meningitis


, especially in infants and the elderly. Before antibiotics


widely used, 70 percent or more of bacterial meningitis cases with fatal consequences, with


antibiotics, mortality decreased by 15 percent or less. Bacterial meningitis is most common in winter and spring. Three bacteria


cause most cases:



Haemophilus influenzae, Neisseria meningitidis


or pneumococcus. Haemophilus meningitis is often caused by Haemophilus


infection type B, also known as Hib. Before effective vaccines were available


and widely available, Hib was the most common cause of bacterial meningitis


children aged 5 years and younger. In Illinois, the average


230 cases annually. However, from 1985 to 1996 by 82 percent



reducing Haemophilus influenzae meningitis. Now


. averages 50 cases per year, mortality is about 5 percent. This is a >> << a significant reduction is due to the routine use of vaccines against Hib. Meningococcal meningitis caused by


Neisseria meningitidis, is primarily a disease


infants, with incidence decreasing in


those older than 1 year. The disease is most common during winter and spring


In some people, the bacteria can cause severe blood infection called


meninhokokkemiya. Illinois average of 115 cases of meningococcal disease in the year;


about 10 percent are fatal. Pneumococcal meningitis caused by pneumococcus


(pneumococcus), usually affects children, the elderly and people with


certain chronic diseases. On average 100 cases are in Illinois


year. Overall, 5 percent to 10 percent of cases lead to death, but in


persons with significant underlying disease mortality can be 20 percent of the


to 40 percent. How it spreads? Meningitis is very contagious. Both viral meningitis and bacterial meningitis >> << can spread by direct contact with nose and throat.


Healthy people who have no signs of the disease may have the bacteria


in the nose or throat, and distribute them to others. Share a glass


cup or eating utensils, coughing or sneezing in the face of another person, or


sharing cigarettes are examples of how contact with alien


respiratory secretions may occur. Viral meningitis can be transmitted fecal pollution (


. except respiratory), when the infected person or canopies highlights


virus in his / her chair. What are the symptoms of meningitis? Meningitis can produce mild symptoms such as headache, low-grade fever and fatigue


takes two to three days in some patients. In other >> << patients, symptoms can be severe and begin suddenly with fever, headache


and stiff neck accompanied by some combination of other symptoms: loss


appetite, nausea, vomiting, sensitivity to bright light, confusion and sleepiness


In newborns and infants, the classic results of fever, headache and stiff neck >> << may or may not be present. A child may be no symptoms other than being


sluggish, irritable and sleepy, not having sufficient interest in nursing and possibly


vomiting. Purple-red rash may appear with meningococcal meningitis. As meningitis diagnosed? Cerebrospinal fluid can be tested to determine the type of meningitis


causing symptoms. This definition is an important factor in choosing an effective antibiotic for treatment >> << bacterial meningitis. As meningitis treated? Treatment of individuals with viral (or aseptic) meningitis is usually


is to reduce fever and making sure they take plenty of fluids. All >> << three forms of bacterial meningitis, however, require immediate medical attention >> << doctor and can be treated with some antibiotics. Appropriate antibiotic treatment of most common types of bacterial meningitis >> << to reduce mortality by about 10 percent, while


mortality is higher in children, the elderly and persons with certain concomitant diseases >> << . How to prevent meningitis? Transmission of viral and bacterial meningitis can be prevented by


improve care among persons at risk of infection among those >> << that could spread disease. Of paramount importance is the proper hand washing techniques


. Wet your hands with soap and warm water. Rub hands for 10 to 20 seconds


sure you clean under the nails. Rinse under warm running water. Dry >> << hand paper towel or your own clean towel. If paper towels


possible, use paper towel to turn off the tap and throw the towel >> << away. Individuals should cover nose and mouth while sneezing or coughing and


refuse used tissues in no time. Wash your hands after contact with respiratory


, including treatment of contaminated tissues and handkerchiefs. Individuals must not share straws, cups, glasses, water bottles used during sports or recreation


, cutlery, cigarettes, etc. Eating and drinking utensils



should be general and should be used only after the other, is


washed. Confuse people kissing the child, baby or child on


mouth can also help prevent the spread of disease. Prevention of viral meningitis also requires proper hand washing to remove faeces >> << contamination after using the toilet, changing diapers, helping kids with toilet >> << and so on. For meningococcal meningitis, household and other contacts who had


close personal contact with infected people recommended to receive prophylactic antibiotics


often rifampicin, which kills the bacteria that live in the nose and secrets


throat. To contact specific case


Haemophilus influenza meningitis, rifampicin and may be recommended. The disease rarely


is in close contact with


, pneumococcus meningitis. C >> << recommends the use of rifampicin and other prophylactic antibiotics differ


depending on the particular situation, it is best to consult a doctor or


local health department for recommendations. Even purchase strattera if rifampicin or other >> << prophylactic antibiotics taken, close contacts should be observed for any >> << symptoms and should be immediately evaluated by a doctor if symptoms. American Academy of Pediatrics and the Advisory Committee on Immunization Practices
