Tuberculosis is one of the biggest health problems in India
India bears a disproportionately large burden of the world's tuberculosis (TB) rates, as it continues to be the biggest health problem in India. The recently discovered global phenomenon of Totally Drug-Resistant Tuberculosis complicates this situation further.
The TB-affected population is rising in India as a majority of them are unable to afford the treatment drugs prescribed. At present, only 1.5 million patients already under the Indian government's care get free treatments for regular TB. Patients who seek treatment in India's growing private sector struggle to buy drugs for themselves.
Tuberculosis, an ancient and deadly bacterial disease that most commonly affects the lungs, has been curable for decades using a cocktail of antibiotics taken for six months. However, the bacteria have mutated into more drug-resistant forms which have become difficult to treat.
Treatment of Tuberculosis
It is a common disease in developing countries, and has been reappearing in developed countries because of the migration of population and other diseases lowering human immunity. It is amongst the ten leading causes of death and one of the most common causes of death in children. Treatment is done using a combination of drugs and surgery.
The aims of TB treatment are:
- To cure the patient of TB and restore their quality of life and productivity
- To prevent the relapse of TB
- To reduce the transmission of TB to others
- To prevent the development and transmission of drug-resistant TB
Drugs
There are more than twenty drugs available for TB treatment. They are used in differing combinations in different circumstances. Few TB drugs are only used for the treatment of new patients when there is no suggestion of any drug resistance. Others are only used for the treatment of drug-resistant TB. The new TB drugs bedaquiline and delamanid are also available to be used for the treatment of MDR-TB.
More than 90% people with drug-susceptible TB can be cured in six months using a combination of first line TB drugs. The bacteria die very slowly, and so the drugs are to be continued for quite a few months. Even when a patient starts to feel better, they can still have bacteria alive in their body. All the drugs must be taken for the entire period of the TB treatment. If only one or two TB drugs are taken, then the bacteria may not all be killed.
