Single sourceInfectious Diseases Interpretation
We are simultaneously winning wars and losing battles on the global health chessboard, as remarkable declines in diseases like HIV and polio starkly contrast with the relentless march of ancient plagues like tuberculosis and malaria, alongside newly surging threats like antimicrobial resistance, reminding us that progress is neither linear nor permanent.
