How can we treat multidrug-resistant tuberculosis?

It is estimated that approximately 10 million people currently have tuberculosis (TB) worldwide, with more patients dying from TB each year than from any other infectious disease.Approximately 5% of people with TB have a form of the disease that is resistant to rifampicin, one of the most effective and commonly used drugs used for treatment.Most of these patients also have resistance to isoniazid, another important drug used for treating TB.Based at University College London, Professor Andrew Nunn's research aims to develop an effective regimen to treat patients with drug-resistant TB and thereby reduce its spread.
