At GHTC, we get to read stories every day about incredible innovations in global health. Most of the technologies we see are inventive, some are revolutionary, and a few are so unusual, one might think they were ripped from the pages of a science fiction novel. Now, we’re testing how well you know these global health technologies with our annual Halloween game: the TRICK or TREATment quiz.For each question, we will present a description of a global health technology. Choose TREATment if you believe this innovation exists. Choose TRICK if you think we are trying to pull one over on you and, instead, the product is still in development or is just a figment of our imagination.

The pill, which is the first-ever drug to show antiviral activity against dengue, will also be tested as a treatment method. If the drug is successful in larger-scale trials, ensuring access to the new drug in low- and middle-income countries —especially as the threat of dengue rises in high-income countries alike—will be essential to effectively tackle the disease around the world.The Sabin Vaccine Institute has launched a phase 2 clinical trial for its vaccine candidate against Marburg virus, a lethal filovirus for which there are currently no vaccines or antiviral treatments approved. The trial will take place in Kampala, Uganda, which has experienced various Marburg outbreaks in the past few decades. The single-dose candidate was previously found to be safe and elicit rapid and robust immune responses in phase 1 clinical and non-clinical studies. The ChAd3 platform, which forms the basis of the Marburg vaccine candidate, also undergirds Sabin's Sudan ebolavirus vaccine candidate, which recently received US funding for phase 2 clinical trials. The need for a vaccine against both deadly diseases has been brought to the fore by recent outbreaks.Last week, Gilead Sciences Inc. announced PURPOSE 5, the first phase 2 clinical trial to evaluate an investigational, long-acting HIV prevention option in Europe. Lenacapavir for HIV prevention, compared with a currently used drug combination, could offer a fewer-dose, long-acting solution to individuals who could benefit from pre-exposure prophylaxis (PrEP). Lenacapavir, which can be administered as a twice-yearly injection, is currently approved in combination with other antiretrovirals for HIV treatment in people with multidrug-resistant HIV-1 infection. The study has an intentional focus on recruiting participants who are disproportionately affected by HIV and often underrepresented in clinical trials, given the importance of making available a variety of HIV prevention methods to meet the diverse needs of those who could benefit from PrEP.

In recognition of World Mosquito Day on August 20, 2023, GHTC is testing our readers’ knowledge of mosquito-borne diseases and ongoing efforts to develop treatments, vaccines, vector-control innovations, and other tools to outsmart the world's deadliest animal. Test your knowledge by taking the quiz below!

Malaria is one of the world’s oldest and deadliest diseases. Thanks to international efforts to develop and scale up prevention tools and treatments, significant gains have been made over the past few decades in fighting this dangerous disease. But challenges, such as growing drug and insecticide resistance and disruptions from COVID-19, have hampered control efforts. In 2021, there were 247 million malaria cases as cases have continued to rise between 2020 and 2021—indicating progress against the disease has stalled and underscoring the need for continued research and development of new tools.In recognition of World Malaria Day, test your knowledge of this deadly disease and the innovations being advanced to end malaria:
