Tests to detect clustering of infected individuals within families.
نویسنده
چکیده
A new simple test to detect within-family clustering of infected individuals is proposed. The test is derived as the score test for several different parametric models designed to allow an increased within-family infectivity. The new test is compared with other tests proposed to detect the same type of clustering caused by increased within-family infectivity. Applications of household disease data and simulations are used to illustrate the theory.

Interpretation of Serologic Test Results and Evaluation of Humoral Immune Response After Vaccination Following Infection with COVID-19 Disease
SARS-CoV-2 virus infection induces a cellular and humoral mediated immune response and produces antibodies against viral antigens such as nucleocapsid (N) protein and spike (S) protein. Anti-protein S antibodies also target the spike protein subunit S1 and the receptor binding domain (RBD). Serologic tests can detect the presence of these antibodies in blood serum within a few days to a few wee...
متن کاملExtraction of the Outer Membrane Proteins of H. pylori and Evaluation of Their Presence in Stool of the Infected Individuals
Helicobacter pylori infections are accompanied with the release of some antigenic material into the stool. Outer membranes proteins (OMP) are among the major antigens of bacteria, which in comparison with other bacterial constituents have less cross-reactivity. In this study, OMP of H. pylori were isolated from 11 clinical isolates and rabbit antiserum against them was used to detect possible a...

The potential uses of serological tests that detect HCV core antigens in biological fluids are highlighted. The most common serological tests utilized to detect exposure to HCV rely on the detection of antibodies to HCV. However, these tests cannot distinguish between individuals who have resolved their infection and those who remain actively infected with HCV. By contrast, the HCV core antigen...
متن کاملBotOnus: an online unsupervised method for Botnet detection
Botnets are recognized as one of the most dangerous threats to the Internet infrastructure. They are used for malicious activities such as launching distributed denial of service attacks, sending spam, and leaking personal information. Existing botnet detection methods produce a number of good ideas, but they are far from complete yet, since most of them cannot detect botnets in an early stage ...

ISSR markers were used to determine the genetic variation and sex determination of the three life-stages of 41 samples of Gracilaria corticata from two regions of the Persian Gulf and Oman Sea namely Bostaneh and Lipar. The specimens were cultured in PES media to observe the different life stages. DNA was extracted by modified CTAB method. After screening of 20 ISSR primers, four primers were s...
