Hib was a leading cause of bacterial meningitis, mainly in children aged under 5 years. If two or more children in a nursery or day care center have Haemophilus influenzae type b infection within a 60-day period, adults and children who were in contact with them should be given an antibiotic. Invasive Haemophilus influenzae (Hi) is treated with antibiotics. Haemophilus influenzae is a small, non-motile, non-spore-forming gram-negative coccobacillus isolated exclusively from humans.

Haemophilus influenzae treatment and symptoms. The vaccine has greatly reduced the number of serious Haemophilus influenzae type b infections, such as meningitis, epiglottitis, and bacteremia. The organism is differentiated into 6 capsulated serotypes (Hia to Hif) and non-encapsulated (ncHi) strains. We use cookies to collect information about how you use GOV.UK. Breathing support 2. One species causes chancroid, a sexually transmitted disease.

We’ll send you a link to a feedback form. It does, however, cause bacterial infections such as pneumonia.

This may be important in developing countries where the intravenous route may not be possible.

Treatment includes antibiotics, usually in hospital. The Manual was first published as the Merck Manual in 1899 as a service to the community. PHE also identifies cases reported through the NHS hospital microbiology electronic laboratory reporting system, LabBase2.
The species responsible for the most infections is Haemophilus influenzae. After the bacteria are identified, they may be tested to see which antibiotics are effective (a process called susceptibility testing). An antibiotic, such as ceftriaxone, cefotaxime, or cefuroxime, is given. Children are routinely vaccinated against Haemophilus influenzae type b (see Table: Routine Vaccinations for Infants, Children, and Adolescents). The most prevalent strain is type b (Hib). Six serotypes, based on capsular polysaccharide, have been identified (serotypes a through f). Please confirm that you are not located inside the Russian Federation. Haemophilus influenzae type b (Hib)—not to be confused with seasonal influenza—is a vaccine-preventable disease that is particularly dangerous for young children. Other species cause infections of heart valves (endocarditis) and, rarely, collections of pus (abscesses) in the brain, lungs, and liver. Epiglottitis must also be treated as soon as possible.

In Malawi, Africa, intramuscular ceftriaxone was compared with intravenous ceftriaxone and was not found to increase the mortality rate. Centers for Disease Control and Prevention: Haemophilus influenzae. Following the decline in invasive Hib disease, PHE extended its enhanced surveillance to include all cases of invasive Haemophilus influenzae infections across all age groups in England and Wales (January 2009 onward). Even with treatment, about 5% of children (1 in 20) with Haemophilus influenzae type b (Hib) meningitis will not survive. No other natural host is known. are available from the Health Protection Report archive. Haemophilus influenzae type b (Hib) is a bacterium that causes a life-threatening infection that can lead to serious illness, especially in children. Invasive Haemophilus influenzae (Hi) is diagnosed based on symptoms and laboratory tests. INTRODUCTION. The H. influenzae species is divided into typeable (encapsulated) and nontypeable (unencapsulated) strains.. Among those who live, about 33% (1 in 3) has permanent brain damage. Haemophilus influenzae is a Gram-negative coccobacillus that can cause serious invasive disease in children and adults. We use this information to make the website work as well as possible and improve government services. Which ones are used depends on the severity and location of the infection and results of susceptibility tests. Merck and Co., Inc., Kenilworth, NJ, USA (known as MSD outside of the US and Canada) is a global healthcare leader working to help the world be well.

Haemophilus influenzae is a Gram-negative, coccobacillary, facultatively anaerobic capnophilic pathogenic bacterium of the family Pasteurellaceae. Haemophilus influenzae infections are treated with antibiotics. Symptoms include fever and a severe headache. Type b strains cause invasive disease, most commonly meningitis, predominantly in infants. An artificial airway, such as a breathing tube, may be inserted or, rarely, an opening may be made in the windpipe (a procedure called tracheostomy). Haemophilus influenzae – a small Gram negative coccobacillus isolated primarily from the human respiratory tract 1. Among those who live, about 33% (1 in 3) has permanent brain damage. Depending on how serious the infection is, people with H. influenzae infection may need care in a hospital. If children have a serious infection, they are hospitalized and kept in isolation to prevent other people from being exposed to infected droplets in the air (called respiratory isolation) for 24 hours after antibiotics are started. Only your health care provider can diagnose the disease by using laboratory test results and examining your physical symptoms. H. influenzae is responsible for a wide range of localized a A case of H. influenzae infection is considered invasive if the organism was isolated from a normally sterile site, such as blood culture, cerebrospinal fluid (CSF), joint fluid, pleural fluid, or similar.

Among typeable strains, H. influenzae serotype b (Hib) is the most virulent. Some strains cause infection of the middle ear in children, the sinuses in children and adults, and the lungs in adults, especially those with chronic obstructive pulmonary disease (COPD) or AIDS. Learn more about our commitment to Global Medical Knowledge. Advanced infections can cause potentially serious complications like meningitis, pneumonia, and sepsis. Corticosteroids may help prevent brain damage.

The legacy of this great resource continues as the MSD Manual outside of North America. Figures for laboratory confirmed Hib cases from 2013 and earlier are available from the Health Protection Report archive. Haemophilus ducreyi is a sexually transmitted disease pathogen causing genital ulcers in humans. Its role in human disease is unclear. If people have symptoms of meningitis, doctors do a spinal tap (lumbar puncture) to obtain a sample of the fluid that surrounds the brain and spinal cord (cerebrospinal fluid). It will take only 2 minutes to fill in. These are the mainstays of treatment. The link you have selected will take you to a third-party website. Many species of Haemophilus normally reside in the upper airways of children and adults and rarely cause disease. Hib can affect people of all ages, but can be prevented with vaccination. Haemophilus influenzae are pleomorphic gram-negative rods that commonly colonize and infect the human respiratory tract. Infections are treated with antibiotics given by mouth or, for serious infections, intravenously. You can change your cookie settings at any time. To diagnose the infection, doctors take a sample of blood, pus, or other body fluids and send it to a laboratory to grow (culture) the bacteria.

Medication to treat low blood pressure 3. Conditions such as meningitis (inflammation of the membranes covering the brain), epiglottitis (inflammation of the flap and the top of the windpipe) and pneumonia can develop very quickly and may require urgent medical attention. Prior to routine immunisation, H. influenzae serotype b (Hib) accounted for more than 80% of invasive H. influenzae disease. The bacteria may cause two severe, often fatal infections: Epiglottitis (infection of the flap of tissue over the voice box). Haemophilus influenzae can cause infections in children and sometimes in adults. Your health care provider must report all cases of invasive Hi to your local health authority.
