The head of the U.N. AIDS agency says the number of new HIV infections could jump more than six times by 2029 if American support of the biggest AIDS program is dropped. UNAIDS Executive Director Winnie Byanyima warned that millions of people could die and more resistant strains of the disease could emerge. Since President Donald Trump's announcement the U.S. would freeze all foreign assistance for 90 days, Byanyima said officials estimate that by 2029, there could be 8.7 million people newly infected with HIV, a tenfold jump in AIDS-related deaths of 6.3 million and an additional 3.4 million children made orphans.
