Chapter 1: Importance of Infection
Richard P. Wenzel, MD, MSc
Health is a high priority for any society, and infections remain
a leading cause of disease globally. Infections that occur among
hospitalized patients and become manifest only after 48 hours of
stay are called "nosocomial."
Chapter 2: Organization
Richard P. Wenzel, MD, MSc
A necessary feature for a successful program in infection control
is dedicated leadership that creates a culture for excellence.
Chapter 3: Role of the Microbiology Laboratory in Infection Control
Mohamed Benbachir, PhD
The microbiology laboratory plays an important role in the surveillance,
treatment, control, and prevention of nosocomial infections.
Chapter 4: The Hospital Environment
William A. Rutala, PhD, MPH and David J. Weber, MD, MPH
In the last 25 years, accumulating evidence shows that enviornmental
sources within the hospital are the primary reservoirs of nosocomial
pathogens for hospitalized patients.
Chapter 5: Waste Management
Mussaret Zaidi, MD
Infectious waste requires special procedures for handling, transport,
and storage in order to prevent disease transmission to health care
workers, waste management workers and the community.
Chapter 6: Reuse of Disposable Waste
Samuel Ponce de Leon R. MD, MSc
Reutilization of disposable devices is a common practice in most
hospitals, but there are no well-founded standard guidelines to
assure the quality and the safety of these procedures.
Chapter 7: Hand Hygiene
Professor Didier Pittet, MD, MS
Hand hygiene is the cornerstone of infection. Health-care workers'
compliance with hand hygiene practices remains low. Enhanced compliance
is associated with decreased transmission of infections.
Chapter 8: Isolation of Communicable Diseases
Bart Gordts, MD, MBA
The combination of standard precautions and isolation procedures
represents an effective strategy in the fight against nosocomial
transmission of infectious agents.
Chapter 9: Sterilization
Constanze Wendt, MD, MS
Critical medical devices must be sterilized and kept from being
contaminated before use to avoid infections in patients exposed
Chapter 10: Sterilization and Use of Sterile Products
Mussaret Zaidi, MD
Improperly disinfected medical equipment and devices can harbor
microorganisms that cause infection. Environmental surfaces have
been implicated in endemic as well as epidemic nosocomial infections.
Chapter 11: Is the Health Care Worker a Source of Transmission?
Margreet C. Vos, MD, Phd
Within the hospital, health care workers (HCWs) are often exposed
to infections. Any transmissible disease can occur in the hospital
setting and may affect HCWs. HCWs are not only at risk of acquiring
infections but also of being a source of infection to patients.
Therefore, both the patient and the HCW need to be protected from
contracting or transmitting nosocomial infections by using recommended
infection control measures.
Chapter 12: Antibiotic Resistance
Richard P. Wenzel, MD, MSc
Begun in the 1940's, the antibiotic era is only 60 years old, yet
now is challenged by the worldwide incidence of resistance by microorganisms.
Chapter 13: Managing Antibiotic Resistance: What Works in the
Atef M. Shibl, MRCPath, PhD, and Ziad A. Memish, MD, CIC, FRCPC,
Managing antibiotic resistance in hospitals requires a multifaceted
prevention and control strategy. Antibiotic resistance is a primary
concern for infectious diseases and infection control specialists
and clinicians in hospitals around the world.
Chapter 14: Organizing and Recording Problems Including Epidemics
R. Samuel Ponce de Leon, MD, MSc
Surveillance is the foundation for organizing and maintaining an
infection control program.
Chapter 15: Keeping the Environment Safe with Limited Resources

services have resulted in an overall deterioration in hospital hygiene
practices in health-care facilities of many developing countries.
Chapter 16: Patient Areas
Constanze Wendt, MD, MS
The patient environment harbors a number of potential reservoirs
Chapter 17: Food
Frederick James Bolton, PhD, FRCPath
Outbreaks of foodborne infection continue to be a problem in healthcare
settings, but they are preventable if all food handlers are trained
to understand the sources and transmission routes of food-related
pathogens and practice the basic principles of food hygiene from
preparation to final serving of meals.
Chapter 18: Water
M. Sigfrido Rangel-Frausto, MD, MSc
Despite the fact that hospital water is not sterile, water sources
are an uncommon source of nosocomial outbreaks.
Chapter 19: Laboratory Areas
Andreas Voss, MD, PhD, and Eric Nulens, MD

A pharmacist can play a pivotal role in reducing infection throughout
Chapter 21: Operating Room
Marie-Claude Roy, MD, MSc
Surgical site infections (SSIs) continue to burden surgical patients
with important morbidity, mortality and immense cost. Because SSIs
are primarily acquired during the surgical procedure while the woulnd
is opened, a number of infection control practices in the operating
room merit scrutiny.
Chapter 22: Emergency Room and Receiving Areas
Heike von Baum, M,D and Richard P. Wenzel, MD, MSc
Health care workers in emergency rooms and receiving areas need
to protect themselves from bloodborne infections and also recognize
and attempt to isolate quickly all patients with infections posing
a risk to nearby personnel, patients, and visitors.
Chapter 23: HIV Infection and AIDS in Developing Countries
Philippe Van de Perre, MD, PhD
Fewer thatn 20 years after it was first recognized in Africa, HIV
infection is already the leading cause of adult deaths in many cities
in developing countries and has significantly increased childhood
mortality. Despite considerable efforts to control the epidemic,
HIV continues to spread at a rapid pace in developing countries.
Out of an estimated 42 million people infected with HIV worldwide
as of December 2002, 70% of the adults and 90% of the children were
living in developing countries.
Chapter 24: Tuberculosis

patients, health care workers, and visitors. Recognizing the risk
factors, surveillance, and initiation of prompt infection control
management practices will reduce the morbidity and mortality these
Chapter 26: Skin and Soft Tissue Infections
Antoni Trilla, MD, MSc
Skin and soft tissue (SST) infections are not uncommon in the hospital
setting. In addition to localized complications, SST infections
may cause life-threatening bacteremias or a sepsis syndrome.
Chapter 27: Bloodstream Infections
K Marhoum El Filali, and H. Himmich
Hospital acquired bloodstream infections (BSIs) are related to the
underlying diagnoses and therapeutic invasive procedures. BSIs have
been divided into two groups: primary BSIs, which occur without
any other infectious site with the same organism at the time of
BSI diagnosis (positive blood culture), and the secondary BSIs,
which are subsequent to bacteremia from another infectious site.
Chapter 28: Managing Vascular Catheters
Andreas Widmer, MD, MS
Intravascular catheters are frequent sources of bloodstream infections.
The prevention of these infections should be part of any infection
control program. Surveillance for catheter-related bloodstream infections
requires few resources compared to other nosomial infections, but
has an important impact on the prevention of this most serious type
of nosocomial infection.
Chapter 29: Hospital-Acquired Urinary Tract Infections
Emanuele Nicastri MD, PhD
"The decision to use the urinary catheter should be made with
the knowledge that it involves risk of producing a serious disease."
Even though this statement was made by Paul Beeson about fifty years
ago, it is still relevant for both patients and health care workers.
Chapter 30: Pneumonia
Javier Ena, MD
Nosocomial pneumonia occures in 0.4 to 1.1% of hospitalized patients.
It is the most common infection in intensive care units and the
second most common cause of nosocomial infection overall.
Chapter 31: Diphtheria, Tetanus, Pertussis
Jack Levy, MD
Active immunization of the general population is effective both
in controlling the transmission of these infections in the community
and also of infection in the hospital.
Chapter 32: Measles
SPatrick De Mol, MD, PhD, and Phillippe Lepage, MD, PhD
Measles is caused by rubeola virus, one of the most contagious pathogenic
agents known. Despite progress in global immunization, measles remains
one of the major infectious causes of mortality in developing countries
and is responsible for about 1 million deaths in children each year.
Chapter 33: Transfusions
Sigfrido Rangel Frausto MD, MSc, and Samuel Ponce de Leon R.
Although life-saving, transfusions are not infrequently associated
with life-threatening complications. In the USA alone, between 10
and 12 million units are transfused every year with at least a 1%
risk of complications ranging from allergic reactions to blood-borne
Chapter 34: Mechanical Ventilation
Stephan Harbarth, MD and Didier Pittet, MD, MS
Mechanical ventilation is the main risk factor for nosocomial pneumonia
in critically ill patients.
Chapter 35: Preparing the Patient for Surgery
Helen Giamarellou, MD
Appropriate skin preparation plus antimicrobial prophylaxis can
decrease the incidence of both superficial and deep wound infections
(surgical site infection) after certain operations.
Chapter 36: Infection Control in Obstetrics
J.A.J.W. Kluytmans, MD, PhD
Neonatal sepsis and postpartum endometritis can be largely prevented
by simple infection control measuress. However, in developing countries,
they still cause substantial morbidity and mortality. Most infections
are caused by microorganisms of the mothers' vaginal flora.
Chapter 37: Infection Hazards of Human Cadavers
T.D. Healing, MCs, PhD, P.N. Hoffman , BSc, and S.E. J. Young,
Cadavers may pose hazards to those handling them. None of the organisms
that caused mass death in the past (e.g., plague, cholera, typhoid,
tuberculosis, anthrax, smallpox) is likely to survive long after

Handwashing is one of the most important infection control practices
for the prevention of the spread of infection with Streptococcus
pyogenes (Group A Streptococcus).
Chapter 39: Staphylococcus Aureus
Bearman, MD, MPH and Michael B. Edmond, MD, MPH, MPA
Staphylococcus aureus is a major human pathogen that commonly
causes nosocomial and community-acquired infections. It is a highly
virulent organism and is exhibiting increasing antibiotic resistance.
Chapter 40: Enterococcal Species
Michael B. Edmond, MD, MPH, MPA
Enterococci are important nosocomial pathogens because 1) they are
the normal flora in the human gastrointestinal tract, 2) antimicrobial
resistance allows for their survival in an environment with heavy
antimicrobial usage, 3) they contaminate the hospital environment
and survive for prolonged periods of time, and 4) contamination
of the hands of health care workers coupled with poor handwashing
compliance provides the potential for spread in the hospital.
Chapter 41: Pneumococcus
Roman Pallares, MD
Streptococcus pneumoniae (pneumococcus) remains
a magor pathogen for human beings. In recent years, important changes
in the epidemiology of pneumococcal infections have been observed.
Chapter 42: Legionella
Marc Struelens, MD, PhD
Nosocomial legionellosis (also called Legionnaires' disease) is
a serious pneumonia caused by inhalation of Legionella
in aerosols from a contaminated hospital water system. Prevention
should be based on a risk management plan including targeted surveillance
for cases, adequate design and manintenance of water distribution
system, and adherence to appropriate respiratory care practices.
