At least 113 people remain unaccounted for, according to Karixia Ortiz, a spokeswoman for Puerto Rico's Department of Public Safety.
The recovery has moved slowly since Maria struck the US territory on September 20, leaving most of the island without basic services such as power and running water, according to residents, relief workers and local elected officials.
Acting US Department of Homeland Security Elaine Duke will make her second trip to the island on Thursday, DHS spokesman David Lapan said Wednesday.
The visit comes as hospitals throughout the cash-strapped island of 3.4 million people have been running low on medicine and fuel. Some residents and local elected officials have said they expect the death toll to rise.
At least two people have died from leptospirosis, which spreads when the urine of infected animals gets into drinking water, San Juan Mayor Carmen Yulín Cruz told CNN Wednesday. People have been drinking water from creeks contaminated by dead animals, she said.
"We're not out of the woods yet," she said. "We are now starting to see a lot of health issues. ... So we are in a great effort, a great humanitarian effort."
As of Wednesday 89% of the island was without electricity and almost 47% had no phone service, according to a website set up by the Puerto Rican government. Some 43% of the island's 313 bank branches remained closed, it said.\
