In developing countries, where routine vaccination with hib vaccine is not widely available, hib remains a major cause of lower respiratory tract infections in infants flu h sinusitis and children. in the united states, hib disease is not common. it occurs primarily in underimmunized children and in infants too young to have completed the primary immunization series. in 2017, the incidence of invasive h. influenzae disease in children younger than 5 years old was 1. hib: 0. 18 cases per 100,000 2. non-b h. influenzae: 1. 7 cases per 100,000 3. nontypeable h. influenzae: 1. 7 cases per 100,000 nontypeable h. influenzae now causes the majority of invasive h. influenzaedisease in all age groups. in 2017, the incidence of invasive nontypeable h. influenzaedisease was 6. dua cases per 100,000 in adults 65 years of age and older. nontypeable h. influenzaealso causes 30% to 52% of episodes of acute otitis media and sinusitis in children. it can be a common cause of recurrent otitis media. Haemophilus influenzae are gr-negative bacteria that can cause infection in the respiratory tract, which can spread to other organs. infection is spread through sneezing, coughing, or touching. H. influenzae most often cause ear, eye, or sinus infections. they also cause pneumonia. a strain of the bacteria that causes more serious disease is called h. influenzae type b. the type b strain is now rare in the u. s. because of the hib vaccine. The following groups are at increased risk of hib disease: 1. unimmunized children younger than 5 years of age 2. household contacts of a person with hib disease 3. daycare classmates of a person with hib disease in addition, the following groups are at increased risk of h. influenzaedisease: 1. children younger than 5 years of age dua. adults 65 years or older 3. american indians and alaska natives 4. people with any of the following medical conditions 4. 1. sickle cell disease 4. 2. asplenia 4. 3. hiv 4. 4. immunoglobulin and complement component deficiencies 4. lima. malignant neoplasms requiring hematopoietic stem cell transplant, chemotherapy, or radiation therapy.

The epidemiology of invasive h. influenzae disease in the united states has shifted since the introduction of the hib vaccine. the united states began using hib vaccine for children in 1987 and for infants in 1990. since then, the annual incidence of invasive hib disease in children aged younger than 5 years old decreased by 99%. now, nontypeable h. influenzae causes the majority of invasive h. influenzaedisease among all age groups in the united states. in addition: 1. rates of hib disease remain stable among adults dua. rates of hib disease remain higher among alaska natives than for other races. H. influenzae is a pleomorphic gr-negative coccobacillus. h. influenzaemay be either encapsulated (typeable) or unencapsulated (nontypeable). there are 6 encapsulated serotypes (designated a through f) that have distinct capsular polysaccharides.
Haemophilus influenzae are gram-negative bacteria that can cause infection in the respiratory tract, which can spread to other organs. infection is spread through sneezing, coughing, or touching.

Sinusitis is one of the most common conditions treated by primary care physicians. Between tiga% to 6% of hib cases in children are fatal. patients ≥65 years of age with invasive h. influenzaedisease (hib, non-b, and nontypeable) have higher case-fatality ratios than children. up to 20% of patients who survive hib meningitis have permanent hearing loss or other long-term neurological sequelae.
For guidelines on treatment and chemoprophylaxis for invasive hib disease, see the red bookexternal icon. cdc recommends chemoprophylaxis for close contacts of hib cases, but does not have guidelines for other types of h. influenzaedisease.
