A research team at Saarland University has demonstrated in a clinical study that a widely used anti-allergy nasal spray containing the active ingredient azelastine can significantly reduce the risk of infection with the SARS-CoV-2 virus. The results of the placebo-controlled trial involving 450 healthy participants have now been published in the leading U.S. medical journal JAMA Internal Medicine.

A new global study has identified striking inequalities in disability caused by COVID-19 during 2020–2021, offering an early warning signal for the ongoing risk of long COVID in the years that followed — and even today. By examining across 920 locations worldwide, researchers found that low- and middle-income countries (LMICs), especially in Sub-Saharan Africa, showed disproportionately high rates of nonfatal COVID-related health loss. These findings highlight potentially hidden vulnerabilities and call for urgent action to address long-term pandemic effects in underserved populations.

The COVID-19 pandemic highlighted how the same health information affects the behavior of individuals differently. A recent study revealed cultural differences in how people respond to hypothetical COVID-19 infection information at the local level. The analysis also found differences in how individual subgroups react differently to pandemic information.
