What Is Zika Virus?
The Zika virus spreads through mosquito bites with usually fairly light symptoms. Outbreaks have occurred in Africa, Southeast Asia and the Pacific Islands. In recent years, the virus gained a foothold in Brazil. It has since been moving northward infecting mosquitoes and humans in 97 countries. There is currently no vaccine to prevent Zika and no medicine to treat it. The best protection is through preventing mosquito bites and avoiding regions with the virus.
While Zika’s symptoms are generally mild, pregnant mothers and their unborn child have the greatest risk. The virus can cause birth defects in babies whose mothers contract the it while pregnant. The exact nature of all defects and when they are most likely to occur is still under investigation.
How Does Zika Virus Spread?
As a mosquito-borne disease, Zika spreads among mosquito populations and from them to humans.
The species that carry Zika virus are the Aedes aegypti mosquitoes.
The Aedes aegypti also carry dengue fever, yellow fever and chikungunya. They usually lives in tropical areas, with populations in Asia, Africa, Australia and the Americas. Not every region has active Zika transmission. The Aedes aegypti mosquitoes bite in day. But, they be found at night in busy areas.
A mosquito will be infected with the virus after biting a person who has Zika. The insect can then spread Zika to any human it bites.
Zika can also be transferred from person-to-person through sexual contact. A person can spread the virus to a sexual partner even if they are not showing any symptoms. Men carry Zika for a longer period of time than women and can spread the virus at least 6 months after infection.
Rarely, a mother infected with the virus will pass it on to her child in utero. This form of transmission is under investigation by global health organizations. There have been no reports of infants contracting the virus through breast feeding.

“Great Clinic“
“This clinic was recommended by my daughters pediatrician, since we were worried about Zika for her travel to the Dominican Republic. The nurse was very thorough. She went over my daughter’s shot record. Walked us through what was recommended and all of our options. Greatly appreciated the many suggestions on what she could get for her trip to help keep her safe. This is an excellent service.”

“Fantastic Visit“
“I’m really sold on Passport Health now that I’ve recently visited to have my tetanus, typhoid and Zika prevention. The nurse was highly informative and went over a detailed review of my upcoming trip to Morocco, as well as general information that is valuable for all travelers. She was extremely knowledgeable about all aspects of potential health hazards abroad and did a good job with the injections, as well. This is a place that doesn’t rush the entire process but takes time to go over everything with great thoroughness. I will only be getting my immunizations here in the future due to their professionalism.”

“One Stop Shop“
“Since my Medicar didn’t cover shots for a trip to Indonesia, I came to Passport Health and so glad to find this great travel resource! They go far beyond just a health clinic for shots with travel kits for safe water, mosquitoes and a handy spiral book with essential info about the region you are traveling! The nurse was professional, gentle and took time to talk through options for meditation.”

“Great visit“
“The nurse was very friendly and thorough. She went through my trip with me and gave me all of my options for prevention. She was patient and gave me time to make decisions. As an aside, Passport has, in my opinion, the best bug repellent on the market. I used it on a trip to Peru for Zika and was the only one in my hiking group that did not get bitten by mosquitos.”
