Two new studies draw on data from more than 12,000 patients to help figure out ways to battle antibiotic-resistant tuberculosis.
Though doctors and advocates have helped speed up access to the antiviral pills – of which the U.S. has enough to treat 1.7 million people – health providers are few and forms are still required.
Their prediction stemmed from the eradication of smallpox. Here's what they said more than three decades ago — and how it foreshadowed events of 2022.
Two years ago, on March 11, 2020, the World Health Organization declared a global pandemic. Now there's talk that we may be approaching a new stage for SARS-CoV-2. Let's unpack the word "endemic."
