RIO DE JANEIRO - Brazilian authorities in the southern city of Joinville are warning residents to guard against fraudsters after three thieves posing as health workers working to wipe out the Zika virus entered a home and ran off with cash and electronics.

Security camera footage obtained by the G1 news site shows two men wearing Brazilian army uniforms and a third wearing the white jacket of a health inspector. The report says they got into the home on Friday by stating they belonged to the city's health inspection team.
