TB drug resistance rises
Resistance to drugs for tuberculosis is rising sharply in England, Wales and Northern Ireland, a Health Protection Agency study reports.
The researchers analysed susceptibility data among a cohort of 28,620 tuberculosis cases dating from 1998 to 2005.
The proportion of cases resistant to isoniazid increased from 5% to 7%, and resistance to rifampicin increased marginally from 1.0% to 1.2%. Multi-drug resistance also increased marginally, from 0.8% to 0.9%.
