A Virginia resident who travelled outside the United States has tested positive for the mosquito-transmitted Zika virus, the Associated Press reports.

Virginia Health Commissioner Dr Marissa Levine said the resident travelled to a country where the Zika virus transmission is ongoing, according to AP on Tuesday.

Levine said this person poses no risk to other residents, because it is not mosquito season in Virginia.

The mosquito-borne virus has been linked to brain damage in thousands of babies in Brazil.

There is no vaccine or treatment for Zika.

Meanwhile, health officials have issued interim guidelines for health care professionals in the US caring for infants born to mothers who travelled or lived in an area with Zika virus transmission during pregnancy.

The guidelines call for paediatricians to work closely with obstetricians caring for women exposed to the Zika virus during pregnancy, monitoring foetal ultrasounds and testing infants with signs of a birth defect called microcephaly marked by small head size.
