There have been no further infectious cases at the school.
Almost 350 lepers are at large in the city, nearly half of them infectious cases.
In practice, the World Health Organisation sets two main targets: 70% of newly infectious cases should be detected, and 85% of those cured.
Our study implicated that sound TB infection control measures, including diagnosis and prompt treatment of infectious cases should be prioritized.
However, non infectious cases can become infectious (transitions 11 13).
infection in children recently exposed to infectious cases of TB in a high endemic setting.
Timely diagnosis and prompt treatment of infectious cases are the key elements of the international effort to combat TB, providing cure of an individual patient and reducing the spread of TB by rendering infectious cases non-infectious.
Sequential restrictions are applied to travel to and from a city that has crossed the threshold of 1,000 cumulative infectious cases.
In the study we used a conservative operational estimate for the imposition of intervention policies of 1,000 total infectious cases.
Transmission in our model varies dynamically in proportion to the number of infectious cases, and we estimate key uncertain parameters including the transmission coefficients.
We have also considered simultaneous, worldwide interventions, in which travel restrictions are applied to all cities after 1,000 infectious cases have occurred in the initially exposed city.
