The so-called emerging infectious diseases like COVID-19, avian influenza, and Ebola highlight the important role of internal medicine in detecting and treating these problems early. Internists deliver first-line care, arrange tests, and institute infection-control measures.
With increasing threats from antimicrobial resistance, doctors also encourage prudent antibiotic use and observe treatment effectiveness. Through a partnership with public health officials and disease surveillance, internal medicine helps prepare the world for future pandemics.
