Phylogenetics in HIV transmission

Phylogenetics of Hiv

A phylogeny is a set of relationships among groups of genes or organisms that reflects their evolutionary history. Inferring a phylogeny is an estimation procedure, a statistical inference of a true phylogenetic tree that is unknown. However, the aim of the phylogenetic analysis is not merely the reconstruction of a tree topology; the phylogeny provides a powerful framework in which several hyp...

HIV/AIDS Disease: Transmission Transition

HIV Modes of Transmission in Sudan in 2014

Background In Sudan, where studies on HIV dynamics are few, model projections provide an additional source of information for policy-makers to identify data collection priorities and develop prevention programs. In this study, we aimed to estimate the distribution of new HIV infections by mode of exposure and to identify populations...

Prevention of Mother to Child HIV Transmission

In Iran 8% of HIV- infected cases are women. Since most of them are young and in childbearing ages, in case of becoming pregnant and not receiving preventive measures, they can infect their child. Without Preventive measures transmission rate is 15 to 45 percent. Several factors such as sever stage of HIV and AIDS ,CD4 low count, high viral loud, acute retroviral phase, STDs, vaginal delivery, ...

The power and pitfalls of HIV phylogenetics in public health.

Phylogenetics is the application of comparative studies of genetic sequences in order to infer evolutionary relationships among organisms. This tool can be used as a form of molecular epidemiology to enhance traditional population-level communicable disease surveillance. Phylogenetic study has resulted in new paradigms being created in the field of communicable diseases and this commentary aims...
