These body fuids should be handled using standard infection control procedures; universal blood precautions should be suffcient to prevent bloodborne transmission. Q fever in children typically is characterized by abrupt onset of fever often accompanied by chills, headache, weakness, cough, and other non specifc systemic symptoms. Illness typically is self limited, although a relapsing febrile illness lasting for several months has been documented in children. Gastrointestinal tract symptoms, such as diarrhea, vomiting, abdominal pain, and anorexia, are reported in 50% to 80% of children. Q fever pneumonia usually manifests as mild cough, respiratory distress, and chest pain. More severe manifestations of acute Q fever are rare but include hepatitis, hemolytic uremic syndrome, myocarditis, pericarditis, cerebellitis, encephalitis, meningitis, hemophagocytosis, lymphadenitis, acalculous chole cystitis, and rhabdomyolysis. Chronic Q fever is rare in children but can present as blood culture negative endocarditis, chronic relapsing or multifocal osteomyelitis, or chronic hepatitis. Children who are immunocompromised or have underlying valvular heart dis ease may be a higher risk for chronic Q fever. The infectious form of C burnetii is highly resistant to heat, desic cation, and disinfectant chemicals and can persist for long periods of time in the envi ronment. The most common reservoirs for human infection are domestic farm animals (eg, sheep, goats, and cows). Cats, dogs, rodents, marsupials, other mammalian species, and some wild and domestic bird species also may serve as reservoirs. Tick vectors may be impor tant for maintaining animal and bird reservoirs but are not thought to be important in transmission to humans. Humans typically acquire infection by inhalation of C burnetii in fne particle aerosols generated from birthing fuids of infected animals during animal parturition or through inhalation of dust contaminated by these materials. Infection also can occur by exposure to contaminated materials, such as wool, straw, bedding, or laundry. Windborne particles containing infectious organisms can travel a half mile or more, contributing to sporadic cases for which no apparent animal contact can be demonstrated. Seasonal trends occur in farming areas with predictable frequency, and the disease often coincides with the lambing season in early spring. The incubation period usually is 14 to 22 days, with a range from 9 to 39 days, depending on the inoculum size. Doxycycline (2 mg/kg every 12 hours; maximum 100 mg/ dose) is the drug of choice for severe infections in patients of any age and treatment is recommended for 14 days (see Tetracyclines, p 801). Appropriate therapy, if initiated within 3 days of illness onset, can lessen the severity of illness and hasten recovery. Children younger than 8 years of age with mild illness, pregnant women, and patients allergic to doxycycline can be treated with trimethoprim sulfamethoxazole. Chronic Q fever is much more diffcult to treat, and relapses can occur despite appropriate therapy, necessitating repeated courses of therapy.

Adults 65 years of age and older who previously have not received Tdap should receive a single dose of Tdap. Immunizations Received Outside the United States People immunized in other countries, including internationally adopted children, refugees, and exchange students, should be immunized according to recommended schedules (including minimal ages and intervals) in the United States for healthy infants, children, and adolescents (see Fig 1. In general, only written documentation should be accepted as evidence of previous immunization. Although some vaccines with inadequate potency have been produced in other countries, most vaccines used worldwide are produced with adequate quality control standards and are reliable. Therefore, serologic testing or reimmunization may be reasonable for these children (see Unknown or Uncertain Immunization Status, p 36). If serologic testing is not available and receipt of immunogenic vaccines cannot be ensured, the prudent course is to repeat administration of the immunizations in question (see Medical Evaluation of Internationally Adopted Children, p 191). A previous immunization with a dose that was less than the standard dose or one administered by a nonstandard route should not be counted, and the person should be reimmunized as recommended for age. Exceeding a rec ommended dose volume is never recommended, because it may result in theoretical but unproven risks of adverse events. Physicians should not assume that children are protected fully against measles during these intervals. Specifc monoclonal antibody products (eg, respiratory syncytial virus monoclonal anti body [palivizumab]) do not interfere with response to inactivated or live vaccines. Testing for Mycobacterium tuberculosis infection at any age is not required before administra tion of live virus vaccines. Record Keeping and Immunization Information Systems the National Vaccine Advisory Committee in 1993 recommended a set of standards to improve immunization practices for health care professionals serving children and revised the standards in 2002. The standards include the recommendation that immunizations of patients be documented through use of immunization records that are accurate, com plete, and easily accessible. In addition, the standards also recommend use of tracking systems to provide reminder/recall notices to parents/guardians and physicians when immunizations are due or overdue. Immunization information systems address record keeping needs and tracking functions and have additional capacities, such as vaccine inventory management; generation of reports on vaccine usage, including those required for vaccines provided through the Vaccines for Children program; vaccine forecasting; adverse event reporting; interoperability with electronic medical records; emergency preparedness functions; and linkage with other public health programs. Additional information about immunization information systems can be found at This record should be given to parents of every newborn infant and should be handled like a birth certifcate or passport and retained with vital documents for subsequent referral. Physicians should cooperate with this endeavor by recording immunization data in this record and by encouraging patients not only to preserve the record but also to present it at each visit to a health care professional. The immunization record especially is important for people who frequently move or change health care professionals.

The infec tion status of patients should not be disclosed to other participants or the staff of athletic programs. This may be protective for other participants and for infected athletes themselves, decreas ing their possible exposure to bloodborne pathogens other than the one(s) with which they are infected. Wrestling and boxing probably have the greatest potential for con tamination of injured skin by blood. Human immunodef ciency virus and other blood borne viral pathogens in the athletic setting. Athletes should be told not to share personal items, such as razors, toothbrushes, and nail clippers, that might be contaminated with blood. Even if these precautions are adopted, the risk that a participant or staff member may become infected with a bloodborne pathogen in the athletic setting will not be eliminated entirely. Caregivers should cover their own damaged skin to prevent transmission of infection to or from an injured athlete. Hands should be cleaned with soap and water or an alcohol based antiseptic agent as soon as possible after gloves are removed. Wounds must be covered with an occlusive dressing that will remain intact and not become soaked through during further play before athletes return to competition. The decontaminated equipment or area should 1 be in contact with the bleach solution for at least 30 seconds. The area then may be wiped with a disposable cloth after the minimum contact time or allowed to air dry. If the caregiver does not have appropriate protective equipment, a towel may be used to cover the wound until an off the feld location is reached where gloves can be used during more defnitive treatment. Infection Control and Prevention for Hospitalized Children Health care associated infections are a major cause of morbidity and mortality in hos pitalized children, particularly children in intensive care units. Hand hygiene before and after each patient contact remains the single most important practice in prevention and control of health care associated infections. Guidelines for prevention of intravascular catheter related infections are available. The Cystic Fibrosis Foundation published an evidence based guideline for prevention of transmission of infectious agents among cystic fbrosis patients in 2003. Physicians and infection control professionals should be familiar with this increasingly complex array of guidelines, regulations, and standards. Ongoing infection prevention and control programs should educate, imple ment, reinforce, document, and evaluate recommendations on a regular basis. The Healthcare Infection Control Practices Advisory Committee in 2007 updated evidence based isolation guidelines for preventing transmission of infectious agents in health care settings. Adherence to these 1 isolation policies, supplemented by health care facility policies and procedures for other aspects of infection and environmental control and occupational health, should result in reduced transmission and safe patient care.
