Common Challenges of Tuberculosis
- Timely detection and correct diagnosis
Early detection of TB is important to prevent further transmission. Diagnosis is often delayed for TB, which can be due to multiple factors: lack of knowledge of the disease in low-incidence settings, non-specific symptoms (especially in the case of HIV co-infection and extrapulmonary TB), and inadequate access to healthcare for vulnerable groups.
- Completion of treatment
Completion of treatment is important to cure patients and prevent transmission. TB treatment involves taking a combination of drugs for several months. The treatment often causes side-effects and can be costly. Unfinished treatment or non-compliance to the prescribed treatment is problematic as it can lead to drug-resistance. TB patients often face difficulties in adhering to treatment and therefore require patient-centred support to enable them to follow a full course of treatment.
- Multidrug-resistant (MDR) and extensively drug-resistant (XDR) TB
Variants of TB that are resistant to antibiotics are more difficult and expensive to treat, and have higher fatality rates. Their spread is a major challenge to the elimination of TB.
