Emergence of multi-drug resistant tuberculosis (MDR-TB) and extensively drug-resistant tuberculosis (XDR-TB) in recent years, and the challenges they pose to tuberculosis control.
Tuberculosis (TB) is a curable disease, but it can be fatal if not treated properly. In recent years, there has been an emergence of multi-drug resistant tuberculosis (MDR-TB) and extensively drug-resistant tuberculosis (XDR-TB), which pose significant challenges to TB control. These emerging strains of TB are resistant to the most commonly used anti-tuberculosis drugs, making them difficult to treat and requiring prolonged and expensive treatment regimens.
Key Takeaway:
Increased Complexity of Treatment: Treating MDR-TB and XDR-TB requires complex treatment regimens, often involving combinations of several drugs, which can be difficult to manage and can lead to side effects.
Reduced Treatment Success: Due to drug resistance, MDR-TB and XDR-TB are more challenging to treat, resulting in lower cure rates and increased risk of treatment failure.
