Officials in New Jersey announced Thursday that a second person in the state had tested positive for the new coronavirus, just one day after they said that a 32-year-old man in Fort Lee was the first in New Jersey to test positive for the virus.

The announcement came as more than 150 cases of the virus were confirmed across the United States in 18 states.

New Jersey’s Department of Health said it was waiting for a more detailed analysis by the Centers for Disease Control and Prevention to confirm “presumptive positive results” from both tests, which were conducted in a state laboratory.

The first positive test came from a health care worker who works and lives in New York City but also has an apartment in Fort Lee, said the mayor of Fort Lee, Mark J. Sokolich.
