NYC sees largest increase in tuberculosis cases in 26 year

The number of tuberculosis cases in New York City suddenly jumped by 10 percent last year — the largest increase since 1992, according to the Health Department.

TB is a highly infectious bacterial disease that largely attacks the lungs, but can also infect and spread to other organs, including the kidneys, spine or brain.

There were 613 reported cases in 2017, compared to 556 in 2016.

TB has been on the decline in the city since peaking at 3,811 cases in 1992.

In an alert to medical professionals Monday, the Health Department offered no explanation for the surge.

People at high risk for TB include substance abusers and people with HIV.
