The government of Puerto Rico has admitted that more than 1,400 people lost their lives in the aftermath of Hurricane Maria that slammed into the island last year.
In the weeks after the storm, Puerto Rican officials said the storm directly caused 64 deaths.
However, in its report to Congress on Wednesday, it was revealed that 1,427 deaths occurred in the four months after the storm.
The figure also appeared in a draft of the report which was published and opened for public comment on July 9.
In detailing a US$139 billion reconstruction plan, the territory's government said the additional deaths resulted from the effects of a storm that led to cascading failures in infrastructure across the island of 3.3 million people.
The new report makes Maria the second-deadliest hurricane to strike Puerto Rico since records began in the mid-19th century.
The San Ciriaco hurricane of August 1899 was deadlier, with an official estimate of 3,369 killed.
