CASE # 4: ABOUT INFECTIOUS DISEASE PREVENTION AND CONTROL
Hilary S. is a nurse health inspector at the county health department. Nurse Hilary visits businesses in
the community that have the potential to spread infectious diseases to large and/or vulnerable
populations. Today, Nurse Hilary will visit the We Love Kids daycare center and a nearby seafood
restaurant.
The daycare center cares for children ages 1 month to 6 years. To enroll a child in daycare, parents must
show proof that the child is up-to-date on all age-appropriate immunizations or must show proof of
medical or religious exemption. Nurse Hilary finds the records in the office area and confirms that all
children have received the necessary immunizations. She observes that employees use gloves when
changing diapers, cleaning a baby’s spit-up, and tending to a scratched knee from a playground accident.
Employees also wash their hands after each of these events, before and after giving a baby his bottle,
and before entering the 1- to 6-month-old room after leaving the 2- to 3-year-old room. Nurse Hilary
also notices a flyer posted in the employee break room that informs staff of the upcoming mandatory in-
service that will be held to discuss the importance of checking bottles, especially those that contain
breast milk, for the correct name before feeding a child.
The seafood restaurant is a chain restaurant that has become less popular over the past couple of years.
Many customers have complained about the quality of the food. Recently, 20 cases of severe diarrhea
were reported to the health department by people who had just eaten at the restaurant. Nurse Hilary
observes the cooks in the kitchen. The refrigerator and the freezer are kept at appropriate temperatures
for storing food. Food is stored in airtight, plastic containers. Nurse Hilary watches as the cook who is
preparing the chicken for broiling is also in charge of prepping the plates that are going out to the
customers. Upon cutting into a piece of chicken about to go out to the dining room, Nurse Hilary notes
that the center looks pink and undercooked. Pieces of wilted lettuce are scattered on the countertops.
During her 2-hour visit, the main chef washes his hands twice, although he leaves the kitchen four times
for a smoking break.
Questions
1. How is the daycare center providing infectious disease control?
Based on Nurse Hilary's observations, it seems that the We Love Kids daycare center is
following proper hygiene protocols to prevent the spread of infectious diseases. The
center has up-to-date immunization records for all children, and employees are using
gloves and washing their hands frequently. The upcoming mandatory in-service on bottle
checking also shows that the center takes its responsibilities seriously.
However, the seafood restaurant appears to have several hygiene issues that could be
contributing to the recent outbreak of diarrhea among customers. The undercooked
chicken and scattered lettuce suggest a lack of attention to food safety, which could put
customers at risk for foodborne illnesses. Additionally, the main chef's frequent smoking
breaks without adequate handwashing could potentially spread germs to the food he is
preparing.
Nurse Hilary's role as a nurse health inspector is to identify potential health hazards and
work with the businesses to implement corrective measures. In this case, she could
recommend that the seafood restaurant improve its food safety protocols, such as by
implementing stricter handwashing policies, training staff on proper cooking
temperatures and techniques, and increasing supervision in the kitchen. Nurse Hilary
could also follow up with the restaurant after a certain period to ensure that the corrective
measures have been implemented.

practices and emphasize the importance of continuing to maintain high standards of
hygiene. She could also offer any additional recommendations or resources that could
help the center further improve its infection prevention protocols.
Based on Nurse Hilary's observations, the daycare center is providing infectious disease
control in several ways. First, the center requires parents to provide proof of age-
appropriate immunizations or a medical or religious exemption before enrolling their
child. This policy helps ensure that all children at the center are protected against
vaccine-preventable diseases, which can spread quickly in group settings like daycare
centers.
In addition, the employees at the center use gloves when changing diapers, cleaning up
after a baby, and tending to a child's injuries. They also wash their hands frequently,
including before and after feeding a baby, and before entering the room for the youngest
infants. These practices help prevent the spread of germs and infections between children
and staff.
Furthermore, the center has a flyer posted in the employee break room that announces an
upcoming mandatory in-service to discuss the importance of checking bottles before
feeding a child, especially those containing breast milk. This shows that the center is
taking steps to educate its staff on proper hygiene protocols and is committed to
maintaining a safe and healthy environment for the children in its care.

medication administration.
Overall, effective infectious disease control in a daycare setting requires a multifaceted
approach that involves a range of policies, procedures, and practices. By implementing
such measures, the daycare center is helping to protect the health and well-being of its
staff, children, and the wider community.
It's worth noting that the effectiveness of infectious disease control measures in a daycare
center will depend on a number of factors, including the specific infectious diseases that
are prevalent in the community and the demographics of the children served by the
center. For example, a center that serves a high proportion of immunocompromised
children may need to take additional precautions to prevent the spread of infectious
diseases.
To ensure that infectious disease control measures are effective, the center may need to
engage in ongoing monitoring and evaluation. This could involve tracking illness rates,
conducting regular assessments of hygiene and infection prevention practices, and
gathering feedback from parents and staff members about the effectiveness of current
policies and procedures.
Finally, it's important to note that infectious disease control is an ongoing process that
requires ongoing attention and adaptation. As new infectious diseases emerge and evolve,
and as new information becomes available about effective prevention and control

2. Describe the outbreak of diarrhea.
A. Endemic
B. Epidemic
C. Pandemic
Based on the given information, the outbreak of severe diarrhea reported by 20 people who had
eaten at the seafood restaurant is most likely an epidemic.
An endemic is a disease that is regularly found in a particular geographic area or population. It is
essentially the "baseline" level of a disease that is always present to some degree.
A pandemic is an outbreak of a disease that spreads across a wide geographic area and affects a
large number of people, often across multiple countries or continents.
An epidemic, on the other hand, is a sudden increase in the number of cases of a particular
disease above what is normally expected in a particular population or geographic area. In this
case, the sudden increase in severe diarrhea cases reported by people who had eaten at the
seafood restaurant suggests that there was an outbreak of a foodborne illness, which would be
considered an epidemic.
It is important to note that the term "epidemic" can also refer to the spread of a disease in a
specific population or group, such as an outbreak of a sexually transmitted infection among a
particular community. However, based on the given information, it seems that the outbreak of

3. Which of the five keys to safer food does the restaurant not follow?
The restaurant does not follow the fourth key to safer food, which is to cook food thoroughly.
The undercooked chicken observed by Nurse Hilary indicates that the restaurant is not properly
cooking their food to the recommended temperature to kill harmful bacteria, which can lead to
foodborne illness. Additionally, the fact that the chef leaves the kitchen frequently for smoking
breaks without properly washing his hands each time also violates the second key to safer food,
which is to separate raw and cooked foods to prevent cross-contamination.
Cross-contamination occurs when harmful bacteria from one food item is transferred to another
food item, either directly or through contaminated surfaces or utensils. This can occur when raw
and cooked foods are stored or prepared together, or when utensils used to handle raw food are
not properly cleaned and sanitized before being used on cooked food.
In this case, the fact that the same chef who is handling raw chicken is also in charge of prepping
the plates that are going out to the customers suggests that there is a risk of cross-contamination.
Additionally, the presence of wilted lettuce scattered on the countertops suggests that proper
cleaning and sanitation protocols may not be in place to prevent the spread of harmful bacteria.
Overall, it is clear that the restaurant is not following the recommended food safety practices to
prevent the spread of infectious diseases. As a health inspector, Nurse Hilary has an important
role to play in ensuring that the restaurant takes the necessary steps to correct these issues and
