Even in ‘normal’ times a reliable supply of medical oxygen is an essential part of healthcare services, but during COVID-19 surges the need for this life-sustaining gas has spiked to unprecedented levels. Tiyese Jeranji explores the fascinating science and engineering that facilitates this substance’s long journey from a production plant to a person’s lungs.
Among several significant barriers to accessing abortion services, experts cite a lack of management support at health facilities, costs, fear of breach of confidentiality and stigma. Many of these barriers are compounded in rural areas. Tiyese Jeranji reports.
It has been over a year since the world saw the first confirmed case of COVID-19, yet the science behind the virus’ physical impact on children remains relatively unclear. Kathryn Cleary spoke to two experts in paediatrics and immunology to get an update on what we have learnt so far.
The shortcomings of healthcare services in the rural Eastern Cape is well documented. Now, with provinces gearing up for the COVID-19 vaccine rollout, Luvuyo Mehlwana asked local health activists and government leaders about the rollout plan for rural communities in the province.
Government deserves criticism for various aspects of its COVID-19 response, but some social media criticism following Sunday’s announcement that the Oxford University/AstraZeneca vaccine has little or no efficacy in preventing mild-to-moderate disease caused by the 501Y.V2 variant has been unfair, writes Marcus Low.
While local experts generally welcome the order in which vaccines will be provided to different categories of people in South Africa, they are concerned that some practical nuances are unclear. Elna Schütz reports.
We know antiretroviral therapy can prevent HIV infection, but can natural biological substances do the same? The results of a recent scientific trial have answered this question: Yes, using broadly neutralising antibodies. But what are broadly neutralising antibodies? How do they work? And when will the average person get access to them? Amy Green breaks down the science.
Over 150 000 people who had TB in South Africa in 2018 were not diagnosed, according to findings from South Africa’s long-awaited National Tuberculosis Prevalence Survey. One reason for this is that an unexpectedly high number of people do not show the typical TB symptoms and are never x-rayed. Amy Green reports.
Local researchers have welcomed impressive phase III findings for the Russian-made Sputnik V vaccine published this week in the Lancet medical journal. It is the sixth COVID-19 vaccine found to be effective in preliminary data from a phase III randomised controlled trial and the fourth to have phase III findings published in a leading medical journal.
Local scientists, as part of an international research collaboration, identified chemical compounds with antitubercular and anti-cancer properties that could potentially help in the fight against malaria. The compounds could halt a malaria parasite in its tracks during different stages of the parasite’s life cycle. Kathryn Cleary interviewed two of the researchers about the scientific discovery and the teamwork and infrastructure that made it possible.
According to the National Department of Health HIV prevention pills are now available at 1 227 public sector facilities (36% of the total). While far from the 100% target, this is a substantial improvement on the roughly 160 facilities that provided the pills six months ago. Amy Green reports.
COVID-19 vaccines are coming to South Africa. Here are questions and answers about the vaccine.
