Bill Gates estimates a 10 to 15 percent chance of another pandemic occurring in the next four years, warning that the world remains unprepared. Despite the lessons from COVID-19, he believes the same mistakes are being repeated. Gates advocates for treating pandemics like fires by investing in a global emergency response team, improving disease surveillance, and strengthening public health infrastructure. He highlights the Global Health Emergency Corps as a promising initiative but criticizes governments for not acting quickly enough. Gates stresses that the cost of inaction is far greater than the cost of prevention.
