The identification and targeted testing of contacts of infectious cases of TB is an important TB control strategy.
Two patients, both HCP identified through routine testing of contacts of previously identified patients, reported no symptoms (Table 1).
The case raised questions specific to international travel, postexposure prophylaxis for Marburg virus, and laboratory testing of contacts with fever.
‡Patients had no reported symptoms so no date of onset; they were identified through routine testing of contacts of known patients.
In spite of widespread testing of contacts and enhanced laboratory procedures during the outbreak, very few additional mild cases were identified.
Identification of close contacts of those who are infected should be carefully considered, and decisions about monitoring and testing of contacts should be made primarily on the basis of clinical and epidemiologic risk factors.
We believe that the few children where infection with M. tuberculosis is most likely, may be identified by improved immigrant entry-screening and testing of contacts of cases with infectious tuberculosis.
When Miles Hewstone heard about Waterhead, he was eager to see how it went: a perfect test of his contact hypothesis.
And, as a further test of where contact improvisation can go, Mr. Simonet becomes blind in the last third of the work -- by shutting his eyes.
These observations were supported by environmental swab tests of food contact and nonfood contact surfaces in the plants.
