City of East Grand Rapids issued the following announcement on March 20
Criminals are also spoofing Health Department phone numbers seeking Medicaid/Medicare information. “Spoofing” is when a call appears to be coming from a legitimate government phone number. Criminals may sound professional and be very persuasive. As a reminder, never provide any personal information over the phone unless you have first independently confirmed who you are talking to. 
Though we wish we could suspend criminal activity during the pandemic, we want to remind you that some criminals will prey upon others in these unprecedented times, when people are most vulnerable.
Criminals are exploiting the COVID-19 outbreak in various ways, including impersonating Red Cross volunteers offering coronavirus testing door-to-door.
Red Cross does not provide coronavirus testing. If someone comes to your residence claiming to be with Red Cross, do not open the door and notify the police immediately.
Additionally, if you receive a text message by someone claiming to be a healthcare professional or Red Cross who is selling or giving away supplies, such as masks or testing kits, do not click any links. It is not a legitimate offer.
We encourage you to remain vigilant and certainly report any suspicious activity to us at 9-1-1 or (616) 632-6357.
