SYDNEY, 26.12.19 (SciDev.Net): Australian scientists have successfully blocked the deadliest malaria parasite —- Plasmodium falciparum — in its transmission stage, paving the way for developing preventative therapies to stop the spread of the disease.

Lead researcher Justin Boddey from the Walter and Eliza Hall Institute of Medical Research and University of Melbourne says, “We have built on our previous studies, where we identified in the P. falciparum parasite an enzyme called plasmepsin V, an enzyme essential for the parasite to grow inside red blood cells. We showed that if you inhibit the enzyme’s activity then you can kill the parasites as they are growing in red blood cells.”

Sydney, 12 November 2019 (SciDev.Net): An experimental dengue vaccine has proved 80.2 per cent effective against virologically-confirmed dengue among children and teens aged 4—16 years in the 12 months after a second dose, according to results of phase 3 clinical trials.

“A vaccine with this kind of efficacy could have a substantial impact on public health,” says Derek Wallace, contributor to the trial results, published 6 November in The New England Journal of Medicine. According to the WHO, dengue is one of the top 10 threats to global health, infecting nearly 400 million people and killing up to 25,000 people worldwide annually. There is no specific treatment for the mosquito-borne viral disease, which causes flu-like symptoms, joint and muscle pain and, in severe cases, leads to haemorrhagic fever and death. It is now endemic in more than 100 countries, with Asia shouldering 70 per cent of the disease burden.

Sydney, 21.12.2018 (SciDev.Net): Rural women in low-income households cannot access healthcare services due to distance and financial reasons. However, overall, healthcare access has improved in 27 countries of the Asia Pacific region over the past decade, says a new joint report by the Organisation for Economic Co-operation and Development (OECD) and the World Health Organization (WHO).

Health at a Glance Asia-Pacific 2018 notes that in Nepal and the Solomon Islands, about three in four women with the lowest household income reported difficulties in accessing healthcare due to financial reasons; two in three reported having unmet care needs due to distance.

The report highlights that achieving Universal Health Coverage and the Sustainable Development Goals (SDGs) is based on the “leave no one behind” premise.
