Global Covid cases up 80% as new subvariant rises

Global Covid cases up 80% as new subvariant rises

The number of new Covid-19 cases reported worldwide rose by 80 percent in the last month, the World Health Organization said on Friday, days after designating a new "variant of interest".

New paper out ! We developed a new index to assess drinking water security in Sudan, also looking at geo access to maternities. 18.97 mio ppl are in catchments of water-unsecure maternities, 60% more projected by 2030. doi.org/10.3390/ijerph200322… @unige_ise @ISG_UNIGE @UNIGEnews

The tragedy in Pakistan is a stark reminder of climate injustice. The top map shows which nations are most responsible for excess emissions. The bottom map shows which nations are most impacted by it. Climate breakdown is playing out along colonial lines.

Last Friday, I successfully defended my doctoral thesis in the Global Health program at the University of Geneva. The thesis applies, evaluates, and reviews geographical accessibility models in different settings in LMICs. A scientific body of work with a practical implication.

Gridded population data are essential for research, policy-making and humanitarian action. In our preprint we show how the use of different population data can lead to diverging patterns of healthcare coverage, underscoring an essential source of uncertainty in access modelling.
