Diagnostics of infectious diseases are central to internal medicine, directing appropriate and timely treatment. Internists employ molecular testing, rapid diagnosis, and laboratory-based pathogen identification in treating bacterial, viral, and fungal infections.
Correct diagnosis permits the administration of directed antimicrobial therapy, reducing the unnecessary use of antibiotics and resistance. Internists also organize infection control strategies to decrease transmission in healthcare facilities.
By combining the latest in diagnostic technology with clinical knowledge, internal medicine promotes better patient outcomes, reduces complications, and safeguards public health. Continuous research brings constant improvements in infectious disease treatment.
