DNA fingerprinting and contact tracing.

Contact tracing and disease control.

Contact tracing, followed by treatment or isolation, is a key control measure in the battle against infectious diseases. It is an extreme form of locally targeted control, and as such has the potential to be highly efficient when dealing with low numbers of cases. For this reason it is frequently used to combat sexually transmitted diseases and new invading pathogens. Accurate modelling of cont...

A contact-tracing procedure.

The increase in the number of new cases of gonorrhoea and the apparent expansion of the reservoir of carriers of the disease have directed attention to the need for reviewing contact-tracing techniques. To obtain the opinions of others on this subject, a *questionnaire was sent to the physicians-in-charge of 205 special treatment centres in England in April 1962. From the replies received, it w...

Gossip Codes for Fingerprinting: Construction, Erasure Analysis and Pirate Tracing

This work presents two new construction techniques for q-ary Gossip codes from tdesigns and Traceability schemes. These Gossip codes achieve the shortest code length specified in terms of code parameters and can withstand erasures in digital fingerprinting applications. This work presents the construction of embedded Gossip codes for extending an existing Gossip code into a bigger code. It disc...

Networks, epidemics and vaccination through contact tracing.

We consider a (social) network whose structure can be represented by a simple random graph having a pre-specified degree distribution. A Markovian susceptible-infectious-removed (SIR) epidemic model is defined on such a social graph. We then consider two real-time vaccination models for contact tracing during the early stages of an epidemic outbreak. The first model considers vaccination of eac...
