1. Hepatitis C Infection in Children
Steven Wiersma, MD, MPH, Deputy State Epidemiologist
Some very good questions were raised at the Annual Statewide Epidemiology Seminar about
the natural history of hepatitis C (HCV) infection in children and the role of vertical
transmission. A recent paper in the New England Journal of Medicine by Vogt et. al. and an
editorial by Jonas summarize some important new information on this topic (NEJM 1999;
341:866-870, 912-913). This study was done in Germany looking at 458 patients who
underwent cardiac surgery prior to 1991 (mean age of 2.8 years at first surgery) and 458
matched non-exposed children.
It appears that a much lower percentage of persons infected with HCV during childhood
(55%) have detectable HCV RNA in their blood than normally seen with adult infections.
This also contrasts with hepatitis B (HBV) infections where we see a high percentage of
those infected at a young age going on to develop chronic HBV infection compared to a very
low percentage of those infected as adults.
The second important finding was that the clinical illness of those infected at a young
age was less severe than those infected as adults.
Jonas, in her editorial, states:
With the implementation
of blood-donor screening, new HCV infections in children will be acquired primarily
through mother-to-infant transmission. The risk of perinatal transmission from mothers
with detectable serum HCV RNA may be as high as 5 to 10 percent. Given the number of women
of childbearing age with chronic HCV infection, there may be a considerable number of
infections by this route in newborns. There are currently no recommendations to screen
women for HCV infection either before or during pregnancy. One reason is that no effective
means has been identified to decrease the likelihood of perinatal HCV transmission from
women with the virus. The infants of women known to be infected with HCV should be
evaluated at 12 to 15 months of age, when maternal antibodies transferred through the
placenta will no longer confound the results of serologic testing.
The findings of Vogt et al. and other studies suggest that
HCV infection acquired by transfusion in early childhood may resolve without treatment
more commonly than infection acquired later in life. In the children in whom infection
does persist, hepatic injury seems to progress slowly and is typically mild within the
first 20 years after infection. Does this mean that early-onset HCV infection is always a
benign disease? Histologic studies of children with HCV infection confirm that some have
fibrosis; the fibrosis progresses with increasing age and duration of infection. Even in
the prospective studies of adults in which few symptoms and limited morbidity were noted
for up to two decades after initial infection, some patients eventually had substantial
morbidity. We do not know whether more serious manifestations of liver disease will appear
30 or 40 years after infection. Thus, it is important to screen and follow patients who
are at risk for hepatitis C and to do more than simply reassure infected children and
their families.
Unfortunately, many of those found to be HCV positive are given little more than
assurances of dubious value. We continue to develop a prevention and control program that
will inform medical professionals and the public about prevention and control of this
disease and to begin providing services through our public health infrastructure to become
leaders in hepatitis prevention and control.
2. Communicable Disease Epidemiology Training Scheduled for the Florida
Panhandle
The first regional training session this year is scheduled for November 3rd
and 4th in Fort Walton Beach. Future training sessions will be held at other
locations throughout the state. A memorandum regarding the training was mailed to all
county health department administrators/directors the week of October 5th. The
text of the memorandum is included below. The agenda for the panhandle training session is
attached.
INTEROFFICE
MEMORANDUM
DATE: October 5, 1999
TO: County Health Department
Directors/Administrators
County Epidemiologists
FROM: Richard S. Hopkins, M.D., M.S.P.H.
State Epidemiologist
SUBJECT: Communicable Disease Epidemiology Regional
Training
ACTION
REQUIRED: Information DUE DATE:
On behalf of the Bureau of Epidemiology, I am pleased to
announce the resumption of the Bureaus on-site regional epidemiology training
programs for county health department staff members. This action is in response to
expressions of need from the counties as well as our own assessment. We intend to offer
training programs in five regions of the state (northwest, northeast, central, southeast
and southwest) starting this coming November. County health department directors and
administrators will determine which areas are appropriate for their staff members. The
first session will be held in Okaloosa county on November 3rd and 4th,
1999. An agenda will be forwarded to all counties on the week of October 11. Additional
details will be provided as they become available and will be posted periodically in the
Epi-Update.
In the one-and one-half day program, Bureau of Epidemiology
staff and some visiting faculty (primarily county health department epidemiologists) will
provide an overview of epidemiologic principles such as disease surveillance and case and
outbreak investigation. The group will also address specific topics that health
departments have determined to be important to them including rabies management, case
reporting procedures, use of the Epi-Info software, and others. The focus of these
sessions will be epidemiology "for the county health departments." There will be
ample time for interaction about specific issues.
The target audiences for the regional epidemiology training
programs are county health department staff members who are involved in epidemiology.
County health directors and administrators are certainly welcome to attend.
John Werth, the Education and Training Coordinator for the
Bureau of Epidemiology will be managing this activity. He will be periodically contacting
county health directors and administrators to provide updated information and to ask for
assistance in obtaining meeting rooms and for other logistical support. Please feel free
to contact Mr. Werth (Suncom 994-1684) if you are interested in hosting one of the
training sessions or for answers to related questions.
We are truly excited about this renewed effort and the
potential it offers for improving disease prevention in Florida.

3. Bureau of Epidemiology Announces Positions for Bioterrorism
Surveillance
Don Ward, Surveillance Section Administrator
This week, the Bureau of Epidemiology posted notices of anticipated vacancies in its
surveillance section for two career service positions to coordinate and conduct disease
and laboratory surveillance programs to identify potential bioterrorist events. The person
selected for one of the positions (biological scientist IV) will coordinate the state's
bioterrorism surveillance programs. The other position is dedicated to the development of
special surveillance projects such as mortality and syndromic surveillance (health
services and facilities consultant). I
Both positions will be located in Leon County. For additional information
contact Don Ward.
4. Employment Opportunity (Bureau of Epidemiology Webmaster)
The Florida Department of Health is looking for a webmaster for the Bureau of
Epidemiology web site. You will be responsible for the design, development and maintenance
of the premier web site for communicable and chronic disease information in the state. The
position is currently part-time, up to 30 hours per week. We're interested in making
our site the most attractive, easiest to use, most current and helpful health site in
Florida. If you have the skills, interest and desire we need you. Contact Don Ward
in Tallahassee at (850) 410-3319, or Jill Parker at (850) 414-5654.

6. Florida Past - Diseased Teeth Declared A Menace to Health
William J Bigler, PhD
Early in 1929, Dr. Henry Hanson, who had already completed a stint as
Director of the State Board of Health Laboratories, was serving as a district health
inspector in the panhandle region of the state. Later that year, upon the retirement of
Dr. B. L. Arms, he became the State Health Officer, serving until 1935. He also served a
second term as State Health Officer during WW II (1942-45). Apparently, somewhat
frustrated after conducting examinations of school children, he decided to share his
findings with the press. The following excerpts are from an article in the Pensacola
Journal, January 27, 1929 entitled "Doctor Finds Students Have Diseased Teeth - Real
Menace to Health Says Inspector For State After Exams. "
"A
large number of children will be wearing false teeth before they are 20 unless they learn
the error of their ways soon. Some children in the city between the ages of 10 and 14 need
false teeth now." Dr. Henry Hansen, State Board of Health Inspector, is authority for
these statements. He made them after having examined more than 1000 city school children
in connection with standardization of schools.
Starts By Neglect
"It is surprising the number of
parents who allow children to neglect their teeth," Dr. Hansen said. "I make a
partial physical examination for the State Board covering skin, mouth, and throat and
general conditions. I find more trouble with teeth than all of the other portions of the
anatomy combined."
The danger of bad teeth, according to Dr.
Hansen, is not alone the possibility of having to wear false teeth at an early age, but of
having the entire system upset and poisoned.
"Diseased teeth can bring on such
diseases as rheumatism, for instance," the inspector said. "They can lead to a
number of other complications. And the pity of it all is that they could prevented so
easily."
Cards Tell Story
After each examination, the childs
medical history is kept on a card and the parents notified.
"If the parents would take the
precautions and advice offered by this free medical service, these examinations could do a
lot of good," Dr. Hansen said. "Most of the time, however, parents think they
know more about how to take care of the child than anybody else, and simply neglect to
have diseased conditions remedied."

1 Haemophilus influenzae can be the agent responsible for disease under
three of the reportable conditions listed-: "Haemophilus influenzae,
invasive" and under "Encephalitis, post infectious." Cases of Haemophilus
influenzae meningitis are reported under "Meningitis, H. influenzae."
2 The reportable disease rule was revised in July, 1999. Kawasaki Disease,
Histoplasmosis, Reye Syndrome, and Typhus were deleted from the weekly disease table since
cases are no longer reportable as of July 4, 1999. Hepatitis C; perinatal hepatitis B;
hepatitis B +HbsAg, pregnant woman; listeriosis; smallpox, S. aureus (GISA/VISA)
and S. aureus (GRSA/VRSA) were added to the reporting requirements as of July 4,
1999. Paralytic shellfish poisoning is now referred to as neurotoxic shellfish poisoning.
