The vast majority of TB cases can be cured when medicines are provided and taken properly. Between and , an estimated 49 million lives were saved through TB diagnosis and treatment. HIV and TB form a lethal combination, each speeding the other's progress. African region. In there were an estimated 1. WHO recommends a component approach of collaborative TB-HIV activities, including actions for prevention and treatment of infection and disease, to reduce deaths.
Anti-TB medicines have been used for decades and strains that are resistant to 1 or more of the medicines have been documented in every country surveyed. Drug resistance emerges when anti-TB medicines are used inappropriately, through incorrect prescription by health care providers, poor quality drugs, and patients stopping treatment prematurely. Multidrug-resistant tuberculosis MDR-TB is a form of TB caused by bacteria that do not respond to isoniazid and rifampicin, the 2 most powerful, first-line anti-TB drugs.
MDR-TB is treatable and curable by using second-line drugs. However, second-line treatment options are limited and require extensive chemotherapy up to 2 years of treatment with medicines that are expensive and toxic.
In some cases, more severe drug resistance can develop. About 9. This regimen takes 9—12 months and is much less expensive than the conventional treatment for MDR-TB, which can take up to 2 years. WHO also approved in a rapid diagnostic test to quickly identify these patients. By the end of , 70 countries had introduced bedaquiline and 39 countries had introduced delamanid, in an effort to improve the effectiveness of MDR-TB treatment regimens.
Ending the TB epidemic by is among the health targets of the newly adopted Sustainable Development Goals. The Strategy outlines three strategic pillars that need to be put in place to effectively end the epidemic:. The success of the Strategy will depend on countries respecting the following 4 key principles as they implement the interventions outlined in each pillar:. This framework supports the adaptation and implementation of the Global Strategy in countries based on their contextual circumstances.
The AFRO and WHO country offices — working in partnership with governments, United Nations agencies and other global and regional partners, non-governmental organizations and the private sector — have been behind dramatic reductions in illness and deaths from these diseases.
We know how to reduce their impact — proven policies and strategies for prevention, treatment and for some diseases, elimination, are available, but there is much yet to be done. Tuberculosis is a global pandemic, killing someone approximately every 22 seconds — about 1. The COVID pandemic serves as a grave reminder that health threats can travel swiftly across continents and oceans.
Centers for Disease Control and Prevention. Tuberculosis TB is a global disease, found in every country in the world. It is the leading infectious cause of death worldwide. The World Health Organization estimates that 1. Last year, 10 million fell ill from TB and 1.
TB is an airborne disease that can be spread by coughing or sneezing and is the leading cause of infectious disease worldwide. Sometimes the immune system cannot kill the bacteria, but manages to prevent it spreading in the body. You will not have any symptoms, but the bacteria will remain in your body.
This is known as latent TB. People with latent TB are not infectious to others. If the immune system fails to kill or contain the infection, it can spread within the lungs or other parts of the body and symptoms will develop within a few weeks or months.
This is known as active TB. Latent TB could develop into an active TB disease at a later date, particularly if your immune system becomes weakened. The vast majority of TB cases can be cured when medicines are provided and taken properly.
Between and , an estimated 49 million lives were saved through TB diagnosis and treatment. HIV and TB form a lethal combination, each speeding the other's progress. In about 0.
