Health monitoring — human disease The routine monitoring of blood pressure levels is an important part of assessing an individual's health. Blood pressure provides information about the amount of blood in circulation and about heart function and thus is an important indicator of disease.

Drug-resistant tuberculosis (TB) is difficult to control primarily because the bacteria have developed resistance to standard antibiotics, rendering conventional treatments ineffective. When patients fail to complete their full course of medication or receive improper treatment, surviving bacilli can multiply and develop resistance to multiple drugs.123

Managing these resistant strains, such as multidrug-resistant tuberculosis (MDR-TB) and extensively drug-resistant TB (XDR-TB), presents several major challenges:

Complex Therapy: Treatment requires longer durations—often up to two years—and the use of more toxic, less effective agents compared to standard regimens.32
Adherence Issues: The extended length of treatment makes it difficult for patients to maintain consistent adherence, which is critical to preventing further resistance and transmission.32
Limited Access: Delays in diagnosis and restricted access to specialized care complicate management.2
Transmission: Because these strains are harder to cure, they remain a persistent threat to public health, necessitating programs like directly observed therapy to ensure compliance.3
