Redbridge has one of the worst rates of tuberculosis (TB) in London, according to a public health report.
More than 56 residents per every 100,000 in the borough had the potentially deadly disease lst year, when 157 new cases were recorded.
The average rate for England is just 14 and 42 in London.
The city has the highest rate of TB for any western European capital, despite efforts to improve prevention, treatment and control.
Most sufferers were born outside of the UK and aged between 25 and 44.
TB typically attacks the lungs but can also affect other parts of the body. Symptoms include a chronic cough with bloody mucus, fever, night sweats and weight loss.
Dr Yvonne Doyle, London regional director for Public Health England (PHE), said 85 per cent of people are successfully treated for the disease.
She added: “Controlling the spread of this infection must remain a public health priority for London where the rates are consistently high.”
PHE is planning screenings across the city, especially for people from countries with high rates of the disease.
People with risk factors including homelessness and drug or alcohol misuse will also be targeted by outreach services.
