Parts of London have higher rates of tuberculosis than Rwanda or Iraq, according to a new report by the London Assembly.
It shows Newham is the worst affected borough, closely followed by Brent, Hounslow and Ealing - were there are more than 150 cases for every 100,000 people.
Further details revealed London boroughs suffer from higher rates of tuberculosis than the rest of the country with 40% of all new cases last year registered within the capital.
The report also found that the BCG vaccination against tuberculosis, recommended for all newborn babies in London, wasn't offered in eight of the 32 boroughs.
