Argentina May Set Zika Case Record in 2025

According to updated data posted by the Pan American Health Organization (PAHO), the Argentine Republic continues to be confronted with an expanding number of Zika cases.

As of June 11, 2025, this South American country has reported 720 Zika cases this year.

In 2024, only 56 Zika cases were reported by the PAHO.

The Argentine Health Ministry says Zika is a viral disease transmitted by the bite of the Aedes aegypti mosquito. When the mosquito feeds on the blood of a person infected with Zika and then bites others, it can transmit this potentially severe disease.

Pregnant women, whether of reproductive age or sexually active, should take extreme preventive and protective measures. Zika infection during pregnancy is associated with fetal brain abnormalities and other birth defects.

Therefore, pregnant women should avoid travel to an area with active Zika virus transmission, says the Ministry.

From a prevention perspective, avoiding mosquito bites is the best option for a person in 2025, as a Zika vaccine is not yet available.

Currently, the U.S. CDC has not issued a Travel Health Advisory focused on Argentina's Zika outbreak. But does highlight the risk for visitors from chikungunya and measles.
