Contaminated needles not contributing to spread of HIV in Africa

22.02.2005


Injections with dirty or contaminated needles are not contributing to the spread of HIV in sub-Saharan Africa say researchers from Imperial College London and the Biomedical Research and Training Institute, Zimbabwe.



Recently, some scientists have suggested that medical injections with contaminated needles were an important, but ignored, factor in the spread of HIV across sub-Saharan Africa. However, research published today in Public Library of Science Medicine shows that injections with dirty needles are not a major source of HIV transmission in rural Zimbabwe.

Dr Ben Lopman from Imperial College London, based at St Mary’s Hospital, and one of the researchers, says: “Some have speculated that unsafe medical injections are driving the continuing spread of HIV in many sub-Saharan African countries, but with this research we are now able to confidently exclude injections as a major transmission route.”


The researchers analysed data from the Manicaland HIV/STD Prevention Study, which had recruited 1847 men and women aged between 15 and 54 to the three year study. The study collected a range of health and socio-demographic data including self-reported history of STD symptoms and whether the participants had received any medical injections or needle pricks.

40.3 percent received an injection or needle prick during the three year study period, but these individuals were no more likely to acquire HIV than individuals who did not receive injections.

Despite the increased number of injections involved with childbearing and pregnancy there was no link to increased risk of HIV infection.

Dr Simon Gregson, from the Biomedical Research and Training Institute in Harare, Zimbabwe, and one of the researchers, says: “Clearly, it is still possible for an individual to get HIV through unsafe medical injections, but, overall in this population in Zimbabwe, unsafe injections are not an important cause of HIV infection.”

The Manicaland HIV/STD Prevention Study was supported by the Wellcome Trust, UNAIDS and CDC Zimbabwe.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
