CDC Issues Zika Virus Travel Notice for Peru
The Centers for Disease Control and Prevention (CDC) has issued a Level 2 travel notice for Peru due to the ongoing risk of Zika virus transmission. This advisory, categorized as “Practice Enhanced Precautions,” urges travelers to take extra steps to prevent mosquito bites while in the country. The emergence of this notice underscores the continued global presence of the Zika virus and the importance of proactive health measures for international travelers.
Understanding the Zika Virus and Travel Risks
Zika virus is primarily spread through the bite of infected Aedes species mosquitoes. While symptoms are often mild – including fever, rash, joint pain, and conjunctivitis – the virus poses a significant risk to pregnant women, as infection can cause severe birth defects, most notably microcephaly. The CDC’s travel notices are designed to inform the public about health threats in specific destinations, allowing individuals to make informed decisions about their travel plans.
A Level 2 travel notice, like the one issued for Peru, signifies that travelers should practice enhanced precautions. This includes using insect repellent containing DEET, picaridin, or oil of lemon eucalyptus; wearing long sleeves and pants; and sleeping under mosquito netting, especially during peak biting hours. Avoiding areas with active Zika transmission is also recommended when feasible.
The current outbreak in Peru is part of a broader pattern of Zika virus activity in the Americas. The virus was first identified in Uganda in 1947, but gained international attention in 2015-2016 with a large outbreak in Brazil. Since then, sporadic cases and localized outbreaks have continued to occur in various regions. What factors contribute to the persistence of Zika virus in certain areas? Understanding the interplay between climate, mosquito populations, and public health infrastructure is crucial for effective prevention and control.
Beyond Peru, numerous other countries and territories currently have active Zika virus transmission.

Staying informed about the latest travel advisories is a vital component of responsible travel.
The World Health Organization (WHO) also provides valuable information on Zika virus, including global surveillance data and risk assessments. Learn more about Zika virus from the WHO.
