Police and government officials nationwide are warning residents to be wary of potential coronavirus-related scams that target people gripped by fear during a global pandemic. 

U.S. Attorney General William Barr on Friday issued a statement “urging the public to report suspected fraud schemes related to COVID-19.” Included in the statement were a list of potential schemes the Attorney General’s office is aware of, including phishing emails, malicious websites, and illegitimate or non-existent charities. 

Not mentioned in the list of potential schemes but circulating on social media is the threat of people in white lab coats approaching homes, pretending to be from a state’s health department or the Centers for Disease Control and Prevention. In Florida, the Daytona Beach Police Department and the Palm Beach County Sheriff’s Office have both posted warnings about such a scam.

“In reality, they’re attempting to rob the house once they get inside, sometimes by force,” the Daytona Beach Police Department wrote Tuesday. 

A spokeswoman for the Palm Beach County Sheriff’s Office told USA TODAY in an email that the department hasn’t made any arrests regarding this type of scam and that the Facebook post was “precautionary.” 

The Florida Department of Health is aware of the allegations, the department said in an emailed statement to USA TODAY. 

"When the Department receives notification that a person has tested positive for COVID-19, the Department conducts an extensive epidemiological investigation in conjunction with the CDC," the statement reads. "Individuals are then notified by their county health department and instructed to self-isolate for 14 days after their exposure to the virus. During this time, their county health department will be in contact with them via telecommunication to provide regular routine checkups."

The Department of Health doesn't do "at home" tests or sell testing kits. 

"All DOH staff will have a badge displayed," the Florida DOH said in a statement. "If someone is approached at their home by anyone claiming to work for the Florida Department of Health or dressed in protective medical gear, they are encouraged to ask for verification and contact their local sheriff’s office or nearest law enforcement agency."

The CDC did not respond to an emailed request for comment from USA TODAY. 

Scams related to the coronavirus pandemic aren’t new: The Federal Trade Commission earlier in March sent letters to seven companies telling them to stop selling products those companies fraudulently claimed could treat coronavirus.

On Sunday, the Department of Justice announced it took action against "operators of a fraudulent website."

In Maryland, the Centreville Police Department asked residents to report instances of people on the phone claiming to be affiliated with power companies. In the call, the potential scammer will say "due to this pandemic you are being reimbursed for your extra usage of electricity (due to being home more)," according to the police department.

"Scammers will mention a variation of the above information and then proceed to attempt to obtain your personal information to reimburse you," CPD wrote on Facebook. "While power companies are doing what they can to soften the blow for the communities they serve, they will not be calling to request this information from you."

Coronavirus-related scams are popping up in other countries, too. In Canada, Alberta Health Services warned residents of a phone scam in which people are told they tested positive for coronavirus and are then asked for credit card information. 

People are selling counterfeit face masks and hand sanitizer, according to a report for the BBC. 

The US Attorney General is warning us about these coronavirus scams: 

Individuals and businesses selling fake cures for COVID-19 online and engaging in other forms of fraud. Phishing emails from entities posing as the World Health Organization or the Centers for Disease Control and Prevention. Malicious websites and apps that appear to share Coronavirus-related information to gain and lock access to your devices until payment is received. Seeking donations fraudulently for illegitimate or non-existent charitable organizations. Medical providers obtaining patient information for COVID-19 testing and then using that information to fraudulently bill for other tests and procedures.
