Purpose of the Report
The following is a descriptive report of invasive Haemophilus influenzae cases as
reported to the Maricopa County Department of Public, Division of Disease Control,
Office of Epidemiology during the years 2000-2007. The report will encompass the
following:
• A brief overview of the Haemophilus influenzae bacterium and its characteristics
• Methodology
• Case demographics, serotype data, and disease trends
• A discussion addressing data quality and timeliness of reporting
The purpose of this report is twofold: first to define the illness and its trends in Maricopa
County during this time period and second to identify potential areas of improvement in
data quality.

Overview of Haemophilus influenzae
Etiologic Agent
Haemophilus influenzae is a gram negative coccobacilli bacterium which is characterized
as being capsulated or unencapsulated. Among the organisms having a polysaccharide
capsule there are six serotypes designated as a-f with serotype b being the most clinically
significant. Unencapsulated organisms, those not having a polysaccharide capsule, are
categorized as non-typeable.

Clinical Description
Haemophilus influenzae disease manifests within various locations in the body causing
infections such as the more prevalent bacteremia, meningitis, epiglottitis, and pneumonia
to the less prevalent endocarditis. In the United States complications from Haemophilus
influenzae type b (Hib) include fatalities in 3-6% of the cases and as many as 20% of the
cases have permanent hearing damage or other long term health concerns (Centers for
Disease Control and Prevention [CDC], 2008). Symptoms of H. influenzae infections are
generalized and dependent upon where it has manifested in the body. The generalization
of symptoms may present obstacles to diagnosing the disease. Although, Hib is the most
clinically significant, the other serotypes are just as adept at causing illness.
Reservoirs
The reservoir for this organism is the human respiratory tract. During the pre-vaccine
era, the organism could be isolated from the nasopharynx of children that were often
asymptomatic indicating colonization rather than infection. A recent study concluded
that infants who are immunized are less likely to become colonized than those who have
not been immunized. The authors determined that an association existed between levels
of serum antibodies against Hib and the likelihood of being colonized (Fernandez, J.,
Levine, O., Sanchez, J., Balter, S., LaClaire, L., & Feris, J., 2000).
Modes of Transmission
The mode of transmission occurs via person to person through nasopharyngeal droplets
or direct contact with respiratory tract secretions. Entry into uninfected individuals
occurs through the nasopharynx as a result of contact with nasopharyngeal droplets of an
infected person or one who is a carrier. Contact includes the sharing of utensils,
coughing or kissing.

Incubation Period and Period of Communicability
The symptoms of H. influenzae usually occur within one to four days after exposure
(American Academy of Pediatrics, 2006). Conclusive secondary attack rates have not
been established for either household members or children that attend daycare.

5

Epidemiology
The World Health Organization ([WHO], 2005) reports that worldwide Haemophilus
influenzae type b (Hib) is responsible for approximately 3 million cases and 386,000
deaths. These cases primarily occur in developing countries where the disease is not
readily recognized, antibiotic treatment is scarce and a vaccine is not available. WHO
(2008) reports that as of 2007, many African and Asian countries still do not have an
available Hib vaccine.
The vaccine was first used in the United States in 1988. The first vaccine was licensed
for children 18-59 months old and two years later the second vaccine was licensed for use
in infants. During the nine years following the initiation of Hib vaccinations the
incidence in children less than five years old declined by 99% (CDC, 1998) from 34 per
100,000 (CDC, 1998) to the current rate of 1 case per 100,000 in children less than five
years old (CDC, 2008). New standards established in CDC’s Healthy People 2010
indicate that the goal is to eliminate infections in children under the age of five years old
by creating a herd immunity effect.
The Centers for Disease Control and Prevention is monitoring the progress of this goal by
performing enhanced surveillance in ten states representing approximately 36 million
individuals (CDC Active Bacterial Core Surveillance, 2008).
The following is a graph of U. S. Hib rates in children less than five years old for years
2000-2007.

The Centers for Disease Control and Prevention Active Bacterial Core Surveillance
(ABC) projects the number of cases and fatalities for the U.S. based on their
areas of enhanced surveillance. Table 1 below represents past case projections and the
case fatality rates. As a comparison, the actual number of cases reported to the Centers
for Disease Control and Surveillance is presented in Table 2. It should be noted that the
number of reported cases has steadily increased over the years. This increase in reported
cases is likely due to the enhanced active surveillance in the project areas. Although the
number of reported cases has been increased, it is still assumed that many cases are not
being reported and this account for the discrepancy between the reported and the
estimated number of cases.

Social Risk Factors
Social risk factors for Hib include socioeconomic status, household size, and ethnicity.
United States statistics indicate Native Americans and Alaskan Natives are more likely to
be diagnosed with a Hib than the rest of the population (CDC, 2008). This increased
diagnosis rate is likely due to lower vaccination rates among these groups. Finally, the

7

greatest risk factor is age, with most cases being infected under the age of five years old
and a peak age of diagnosis occurring at six to seven months old.

Prevention
There are two manners in which natural immunity can be acquired. First, immunity is
acquired maternally through breastfeeding or the placenta. Second, immunity is thought
to occur as a result of natural exposure to the organism. Today, in developed countries,
immunity to Hib is more commonly acquired through a series of vaccinations. As
historically Hib was the most clinically significant serotype of the bacterium
Haemophilus influenzae currently is the only serotype that is vaccine preventable.
The following table is the current vaccination schedule for Hib as recommended by the
Advisory Committee on Immunization Practices (ACIP) (CDC, 1991).

incompletely immunized household, childcare, or nursery contacts.

Haemophilus influenzae Surveillance in Maricopa County for 2000-2007
As directed by Arizona Administrative Code (AAC) R9-6-333 invasive Haemophilus
influenzae must be reported within five days after diagnosis and case has been
established. A potential case is defined and classified as follows:
Clinical Description
Invasive disease due to Haemophilus influenzae may produce any of several clinical
syndromes including meningitis, bacteriemia, epiglottitis, or pneumonia
Laboratory Criteria for Diagnosis
Isolation of H. influenzae from a normally sterile site
Case Classification
Confirmed: A clinically compatible illness that is culture-confirmed
Probable: A clinically compatible illness with detection of H. influenzae type b antigen in
cerebrospinal fluid.

8

In addition to reporting the case, Arizona Administrative Code mandates that all
Haemophilus influenzae isolates be submitted to the Arizona State Public Health
Laboratory for serotyping.

Case Investigation Methodology
A total of 651 Communicable Disease Reports for H. influenzae were received by the
Maricopa County Department of Public Health during the years 2000-2007. Three
hundred of these reports were ruled out due to one or more of the following reasons:
specimen source not being a sterile site, out of jurisdiction, duplicate report received or
isolate being of a different Haemophilus species. Five cases were identified through
death certificates and eliminated due to an investigation not being completed. The
remaining cases included in the analysis consists of those classified as probable (2) and
confirmed (344) for a total of 346 meeting the case definition during the years 20002007. Graphs 2 and 3 represent the number and rates of cases reported by years.

Cases are typically reported by health care providers, with 81% (280) of cases coming
from providers. Laboratories reported 19% (66) of cases. Graph 4 summarizes the
number of cases received during this time period and the sources of report by year of
disease onset. The modes of reporting used by healthcare providers are summarized in
Graph 5. The graph indicates that the use of mail to report cases is rapidly declining due
to quicker methods such as the use of electronic reporting, telephone, and fax.

Case Investigation Procedure
Once a case is received by the Office of Epidemiology, a Community Health Nursing
(CHN) staff member will begin investigating the case immediately. The investigation
includes confirming the diagnosis, identifying personal contacts, providing
chemoprophylaxis if necessary and implementing control measures as needed. The
following flowchart is a diagram of the steps implemented to complete an investigation.

Twenty-eight cases reported being vaccinated for Haemophilus influenzae serotype b
(Hib) either completing the vaccine series (43.0%) or partially completing the series,
(57.0%). The most common serotype isolated from these twenty-eight cases was
serotype a which made up 43.0% of total cases.
According to the data collected during the investigations, whites were more likely to
report being vaccinated. Table 6 represents the percentage of children reportedly
vaccinated, during the investigation of Haemophilus influenzae cases, by race/ethnicity.

Haemophilus influenzae serotype b
Seventeen cases were diagnosed with Haemophilus influenzae serotype b. Four of the
seventeen cases were diagnosed in children under five years old. CDC estimates that the
national rate of infection for children under five years old is less than 1 per 100,000 and
Maricopa County is similar to that of the rest of U.S with a rate of 0.2 per 100,000. The
following graphs (17, 18 and 19) and Table 7 exemplify demographics specific to these
cases.

Haemophilus influenzae Data Quality in Maricopa County,
2000-2007
Case data are collected from health care provider and laboratory reports and subsequent
county investigations. The quality of disease surveillance is determined by the quality of
the collected data. One method for assessing data quality is to measure the number of
cases with missing or incomplete data that are present in the database. The following
table exemplifies the number of Haemophilus influenzae cases that have missing or
incomplete data for selected variables. Table 8 shows that basic patient demographic
information is being obtained which enables the county’s community health nurses to
begin an investigation. The table also illustrates that the ever important information
regarding pregnancy is being obtained 97.7% of the time for females between the ages of
14-55 years old. Finally, the serotype was identified for 87.0% of the cases.

Investigation Timeliness in Maricopa County, 2000-2007
Ideally, infectious disease cases should be reported and the investigation completed
before the end of the known incubation period so that further spread of the disease can be
avoided. Unfortunately, this is not always possible. Nevertheless, it is still important for
the case to be reported and the investigation to occur in a timely manner. The following
graph represents the median number of days for each step of the case identification and
investigation for the years 2000-2007. Cases for which a definite end or beginning of
investigation could not be determined or cases missing other pertinent dates such as onset
of disease were omitted from the analysis, 103 (30%) cases. The remaining cases used
for this analysis represented 70% (243) of the confirmed cases.
Graph20. Median Length of Days from Onset of Disease to Completion of Case
Investigation for Maricopa County Haemophilus influenzae Cases for Years 20002007 (N=243)

Current and future research
Current literature illustrates that although strides have been made in the developed world
to effectively decrease Hib there are still unresolved issues. For instance, In the United
States the incidence rate has dropped significantly due to the inception of the vaccine
(Centers for Disease Control and Prevention, 2008) yet this period of enjoyment could be

25

short-lived due to a genetic adaptation of the organism allowing it become more virulent
and causing vaccine failures (Cerquetti et al, 2005).
Such issues also include the rise in the number of the unencapsulated, non-typeable, form
of the bacteria isolated from sterile sites. In a study researchers, using data from several
states, determined that non-typeable serotypes were more commonly isolated from sterile
sites than any other serotype (Dworkin, Park, & Borchardt, 2007). Although Maricopa
County’s data was not apart of this study the results are consistent with data presented in
previous sections of this summary. Future studies should determine if the unencapsulated
organism has adapted to be more virulent or was its magnitude overlooked in the
beginning. An intriguing question for future consideration is now that H. influenzae
serotype b is somewhat contained in the United States will it become necessary to
increase surveillance and create a vaccine for the emerging unencapsulated form of H.
influenzae.
As the data for Maricopa County and past studies have shown African Americans and
Native Americans/Alaskan Natives are disproportionately affected by H. influenzae
primarily type b. Two thoughts abound as to the cause one is that African Americans and
Native Americans/Alaskan Natives are genetically more susceptible and the other is that
both groups are typically in lower socioeconomic strata causing them to reside in close
confined areas (Rust & Cavaliere, 2006). Studies have yet proved, sufficiently, either
thought therefore more research is needed in this area to find the cause.

Conclusions
1. The rate of children less than five years old diagnosed in Maricopa County
between the years 2000-2007 with Haemophilus influenzae type b was less than
the US national rate for the same age group and time period. In fact, Maricopa
County’s rate is close to the U.S. Healthy People 2010 goal.
2. The majority of Haemophilus infections presented as bacteremia/sepsis
3. The majority of infections that are caused by Haemophilus influenzae were nontypeable, these organisms were responsible for more deaths than any other
serotype.
4. Individuals most commonly infected with Haemophilus influenzae, all serotypes
and non-typeable, were over the age of sixty-five and those less than five years
old.
Future actions should include:
•

Increasing the quantity and quality of investigations by the Maricopa County
Health Department

26
•

Encouraging clinical laboratories to send more isolates to the Arizona State Public
Health Laboratory for serotyping thereby decreasing the number of unknown
serotype

•

Investigating the rising number of non-typeable isolates

•

Investigating the causes for the disproportionate number of cases among African
Americans and Native Americans
