Abstract
We encountered a contact group investigation in which differences in environmental factors, including the ventilation frequency and the airflow, led to differences in the infection risk.
The index case was diagnosed with tuberculosis after cough and sputum persisted for 9 months. The...

Abstract
Pertussis is a highly infectious, vaccine-preventable respiratory illness. With the advent of a vaccine, case numbers fell in the United States from a high of 265,269 in 1934 to a low of 1,010 cases in 1976, but then resurged to 25,827 in 2004. During 2004-2008, the average was 18,161 cases per year...

Active pulmonary tuberculosis was diagnosed in a 4-month-old infant 16 days after hospitalization; 186 exposed individuals were traced and one conversion detected. Although the risk of tuberculosis transmission in paediatric hospitals is low, paediatricians in low-incidence countries should maintain...

Abstract
The objective of the study was to examine the factors associated with unidentified tuberculosis (TB) index cases (1987-2007) and to describe outbreaks (2000-2007) of childhood TB cases in Barcelona, Spain. Contact tracing seems to be fundamental in index case identification, but improvement could be...

Abstract
We applied the QFT-2G tests to numerous contact investigations and found that the majority of contacts who had been supposed to be infected with M. tuberculosis (Mtb) based on TST were negative in the QFT-2G tests, strongly suggesting the possibility that the unnecessary preventive chemotheraphy was...

Abstract
Hospital acquired infection mainly occurs at hospitals, not clinics. In Japan, QFT-G is the main tool for the diagnosis of tuberculous infection among health care workers. Contact examinations are basically done for contacts of sputum smear positive TB cases, but infection may occur at fiberbronchos...
