Health officials in Brazil have begun issuing a warning about the possible transmission of the Zika virus.
Officials from the Federal Emergency Management Agency and the Public Health Agency of Brazil issued the alert, which comes after health officials in the country reported a new surge in cases of the virus.
The agency said the new cases came from the northeastern state of Minas Gerais and were mostly among people who live near the border with Paraguay, where the virus was first detected in May.
Officials also reported an increase in cases in the northeastern city of Parana.
The new cases were reported on Monday, the agency said in a statement.
It is unclear how many of the new infections have been confirmed.
