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.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
