Santiago, Chile

Tools to fight hantavirus show promise despite limited funding. A recent outbreak on a cruise ship highlighted the lack of treatments and vaccines for the rare but deadly rodent-borne virus.

Protesters in Chile's capital clashed with police over President José Antonio Kast's education cuts and austerity measures. The march, organized by the Confederation of Chilean Students and supported by teachers' unions and other groups, led to clashes involving water cannons and tear gas. The government's austerity plan includes a $6 billion spending cut and a controversial National Reconstruction bill.
