Presentation
Hib, for example may present as epiglottitis (severe swelling in the throat) or pneumonia. [immune.org.nz]
The most common presentation is pneumonia, which presents as high-grade fever, chills, productive purulent cough, shortness of breath, chest pain, lethargy, and generalized body aches. [ncbi.nlm.nih.gov]
Severe cases may present with convulsions and coma. Infants often present with less characteristic symptoms such as, vomiting, refusal to feed and irritability. [ecdc.europa.eu]
Signs of increased ICP are especially likely to be found in children with a fulminant history and those who are moribund on presentation. [emedicine.medscape.com]

The most significant findings included a positive gram stain, decreased absolute CSF glucose or CSF–serum glucose ratio, increased CSF protein, and an increased band count on CBC. Table 4. [jamanetwork.com]
Treatment
Some people with certain medical conditions have an increased risk of infection, for example, those without a functioning spleen, and those who are immune compromised from a disease or treatment of a disease. [immune.org.nz]
Management and Treatment How is Haemophilus influenzae treated? Haemophilus influenzae treatment depends on the type of infection or disease. Treatment usually includes the use of antibiotics to fight the infection. [my.clevelandclinic.org]
Treatment The primary treatment for Hib is appropriate antibiotics. Intravenous antibiotics, (cefotaxime and ceftriaxone are preferred) are often required but depending on illness, oral administration may follow for 7-10 days. [bu.edu]
Information about a therapy, service, product or treatment does not in any way endorse or support such therapy, service, product or treatment and is not intended to replace advice from your doctor or other registered health professional. [betterhealth.vic.gov.au]
Because it is a bacterial disease, the primary method of treatment for Haemophilus meningitis is anti-bacterial therapy. [en.wikipedia.org]
Prognosis
Prognosis Early diagnosis and treatment of meningitis ensure a good prognosis. Timely initiation of empiric antibiotics and blood culture specimens to help direct management is the best approach to control the disease. [ncbi.nlm.nih.gov]
Outlook / Prognosis What can I expect if my child has a Haemophilus influenzae disease? The outlook (prognosis) for H. influenzae infections depends on the type and severity of your child’s condition. [my.clevelandclinic.org]
Such people include: Household members Roommates in dormitories Those who come into close contact with an infected person Outlook (Prognosis) Meningitis is a dangerous infection and it can be deadly. [ufhealth.org]
[citation needed] Prognosis[edit] Survivors of Haemophilus meningitis may experience permanent damage caused by inflammation around the brain, mostly involving neurological disorders. [en.wikipedia.org]
Etiology
Etiologic agent Clinical features Sequelae Transmission Risk groups Trends Incidence Treatment and chemoprophylaxis Immunization Reporting References Etiologic agent Haemophilus influenzae is a pleomorphic gram-negative coccobacillus. [cdc.gov]

Rates of Hib meningitis and probable bacterial meningitis with no determined etiology declined by 13 and 17 cases per 100 000, respectively. [scielosp.org]
This may include an increased frequency of etiologic agents less common to determined age groups, different CSF characteristics and worse progression. [scielo.br]
All of the serotypes, particularly type b, are common etiological agents in lower respiratory tract infections such as pneumonia. [ncbi.nlm.nih.gov]
