The human leukocyte antigen (HLA) gene complex varies enormously among individuals and helps explain individual variation in immunity to infectious diseases. Ramsuran et al. (Science 2018) examined data from almost 10,000 HIV infections.
The Technology Innovation Agency (TIA) and UKZN have signed an agreement for the establishment of KRISP - the KwaZulu-Natal Research and Innovation Sequencing Platform.
Many parameters are examined to try to understand HIV transmission in endemic areas. Tanser et al. (Science TM 2017) use longitudinal population-based data from rural South Africa to show that population viral load indices incorporating geographical location and local HIV prevalence can be used to infer HIV transmission potential.
The Mercury, 14 December 2017, KwaZulu-Natal-based medical research organisations have developed an improved method to accurately predict where the highest rate of new HIV infections will likely occur in a community. Press coverage of our KRISP paper by Tanser et al. (Science TM 2017)
By Katharine Child, 05 December 2017. SA's policy to reduce HIV infections is to do what the UN recommends, which is to get 90% of people tested, 90% of HIV-positive people taking antiretrovirals and 90% of those on treatment taking it properly so they are not infectious. Press coverage of our KRISP paper Iwuji et al. (Lancet HIV 2017).
By Linda Nordling, 2 December 2017, Quartz Africa. Antiretrovirals 'the drugs used to keep HIV in check' don't only prevent people from getting AIDS; they also keep virus levels low, making those taking them less likely to pass the infection to others. Press coverage of our KRISP paper Iwuji et al. (Lancet HIV 2017).
HIV drug resistance is approaching and exceeding 10% in people living with HIV who are about to initiate or reinitiate first-line antiretroviral therapy, according to the largest meta-analysis to date on HIV drug resistance. Press coverage of Gupta et al. (Lancet ID 2017).
Elevated HLA-A expression impairs HIV control through inhibition of NKG2A-expressing cells.

This tool is designed to use phylogenetic methods in order to identify the HIV-1 subtype of a specific sequence. The sequence is analysed for recombination using bootscanning methods. The version 3 contains new CRFs (CRF01_AE to CRF47_BF).
This is the first version of the Zika typing tool, which uses phylogenetic analysis to identify the species and genotype of the virus.
This is the first version of our Arbovirus typing tool for Chikungunya, Dengue, Yellow Fever and Zika
This is the first version of the Chikungunya typing tool, which uses phylogenetic analysis to identify the species and genotype of the virus.
This is the first version of the Yellow Fever typing tool, which uses phylogenetic analysis to identify the species and genotype of the virus.
