LITTLE ROCK, Ark. – The number of Zika virus cases reported in Arkansas has increased to 13.

The Arkansas Department of Health (ADH) says via its Facebook page that the newest case has been associated with travel to the Caribbean.

The ADH says there have been no reports of Zika being transmitted by mosquitoes within Arkansas so far, but the ADH recommends taking precautions.

Zika virus is a relatively new disease for the Western hemisphere. It first appeared in Brazil in May of 2015. It has since spread to over 35 countries in Central and South America and the Caribbean. Zika is spread through mosquito bites and through sexual transmission from a man to his sexual partner. According to the CDC, the most common symptoms are fever, rash, joint pain and red, itchy eyes. Symptoms are usually mild and last several days to a week. Many people who have Zika will not experience symptoms. There is currently no vaccine or treatment for Zika.

Pregnant women are most at risk for complications from the Zika virus because serious birth defects can occur in children born to women who are infected with the virus.

The Centers for Disease Control has issued travel guidance for women who are pregnant or who may become pregnant.
