View Media Gallery The electron flow, called tube current, is generated through an electrically heated negatively charged filament cathode and is expressed in milliamperes mA. The x-ray tube fires a beam of electrons through a high voltage vacuum tube forming x-rays that are emitted through a small opening. X-rays are generated by engaging a high-voltage switch with the output expressed as the kilovolt peak kVp.

Although investigation of contacts and treatment of infected contacts is an important component of the U.

This statement, the first issued jointly by the National Tuberculosis Controllers Association and CDC, was drafted by a working group consisting of members from both organizations on the basis of a review of relevant epidemiologic and other scientific studies and established practices in conducting contact investigations.

This statement provides expanded guidelines concerning investigation of TB exposure and transmission and prevention of future cases of TB through contact investigations.

In addition to the topics discussed previously, these expanded guidelines also discuss multiple related topics e. These guidelines are intended for use by public health officials but also are relevant to others who contribute to TB control efforts.

Although the recommendations pertain to the United States, they might be adaptable for use in other countries that adhere to guidelines issued by the World Health Organization, the International Union against Tuberculosis and Lung Disease, and national TB control programs.

Inthe American Thoracic Society ATS published brief guidelines for the investigation, diagnostic evaluation, and medical treatment of TB contacts 4. This statement, the first issued jointly by the National Tuberculosis Controllers Association NTCA and CDC, was drafted by a working group consisting of members from both organizations on the basis of a review of relevant epidemiologic and other scientific studies and established practices in conducting contact investigations.

A glossary of terms and abbreviations used in this report is provided Box 1 and Appendix A. Although the recommendations pertain to the United States, they might be adaptable for use in other countries that adhere to guidelines issued by the World Health Organization, the International Union Against Tuberculosis and Lung Disease, and national TB control programs.

Contact investigations are complicated undertakings that typically require hundreds of interdependent decisions, the majority of which are made on the basis of incomplete data, and dozens of time-consuming interventions. Making successful decisions during a contact investigation requires use of a complex, multifactor matrix rather than simple decision trees.

For each factor, the predictive value, the relative contribution, and the interactions with other factors have been incompletely studied and understood. For example, the differences between brief, intense exposure to a contagious patient and lengthy, low-intensity exposure are unknown.

Studies have confirmed the contribution of certain factors: Multiple observations have demonstrated that the likelihood of TB disease after an exposure is influenced by medical conditions that impair immune competence, and these conditions constitute a critical factor in assigning contact priorities 6.

Other factors that have as yet undetermined importance include the infective burden of Mycobacterium tuberculosis, previous exposure and infection, virulence of the particular M.

Further, precise measurements e. No safe exposure time to airborne M. If a single bacterium can initiate an infection leading to TB disease, then even the briefest exposure entails a theoretic risk. However, public health officials must focus their resources on finding exposed persons who are more likely to be infected or to become ill with TB disease.

These guidelines establish a standard framework for assembling information and using the findings to inform decisions for contact investigations, but they do not diminish the value of experienced judgment that is required. As a practical matter, these guidelines also take into consideration the scope of resources primarily personnel that can be allocated for the work.

Methodology A working group consisting of members from the NTCA and CDC reviewed relevant epidemiologic and other scientific studies and established practices in conducting contact investigations to develop this statement.

These published studies provided a scientific basis for the recommendations. Although a controlled trial has demonstrated the efficacy of treating infected contacts with INH 1the effectiveness of contact investigations has not been established by a controlled trial or study.

Therefore, the recommendations Appendix B have not been rated by quality or quantity of the evidence and reflect expert opinion derived from common practices that have not been tested critically.
