Twenty-nine states and the District of Columbia each had more cases in 2015 than 2014, raising questions -- but no definitive answers -- about a possible resurgence of one of the world's deadliest diseases.
The overall increase was relatively small: 157 more cases, bringing the 2015 total to 9,563. Two-thirds of the total were among people born abroad, with Asians accounting for the most cases (3,007) and the highest rate (28.2 cases per 100,000 persons). By comparison, there were only .5 cases per 100,000 whites last year.

More than half of cases reported in 2015 were clustered in four states — California, Florida, New York and Texas — which have one-third of the U.S. population.
