One year after the Zika virus was first confirmed in Latin America, the response from the global scientific community has been resolute, and Southern Research has been there every step of the way.

Experts in our Drug Discovery and Drug Development divisions are working with a sense of urgency to establish the pipelines needed to support research on the fundamental questions behind the virus.

With unique in vitro models and Nonhuman Primate (NHP) and GLP capabilities, our infectious disease research team is fully prepared to add significant value to the development of prophylactic and therapeutic strategies against Zika.

Current capabilities and available services include:

Q&A on Zika virus

  • What is Zika?

    Zika is a small RNA based virus transmitted by the Aedes aegypti and Aedes albopictus mosquito that is spreading rapidly through the Western Hemisphere. It belongs to the same virus family as dengue, yellow fever, and the West Nile, but has proven to be much more complex than the others. For example, Zika is the only virus of the family that can be sexually transmitted. It is also linked to microcephaly, a congenital birth defect that causes babies to be be born with small heads and underdeveloped brains, Guillain-Barré Syndrome, and related maladies, as highlighted in this story from National Public Radio.

  • What should I do to protect myself from getting Zika?

    The most important thing you can do is to educate yourself about the risks of Zika, and take precautions to prevent getting bit by mosquitos, including not traveling to affected areas. Additional precautions include:

    • Wear bug repellant.
    • Be aware that the mosquitos responsible for carrying Zika (the Aedes aegypti and Aedes albopictus ) often live inside homes and other buildings.
    • Remove areas of standing water from your home or yard where mosquitos may lay their eggs — it is very difficult to eradicate the mosquito because they only require a small amount of water in which to lay eggs. But, you can work to limit their density.
    • Be smart about your travel decisions — if you travel to South America, Central America or the Caribbean, there is a reasonable chance you could be bitten by a mosquito carrying Zika.
    • If you do travel, wear long sleeves indoors and outside (remember: the A. aegypti and A. albopictus mosquitoes often live indoors).
    • Upon return from travel, be mindful of the public health and wear long sleeves for at least two weeks – the time period during which humans are most likely to spread the virus.
  • Should I travel?

    Pregnant women, and anyone who is considering becoming pregnant, or who has a chance of becoming pregnant, are encouraged to strongly consider limiting travel to Zika prone regions.

    According to the CDC, there are more than 30 countries and territories on a do-not-travel advisory list for at-risk persons. Most are located in the Americas and the South Pacific. While Zika outbreaks are have yet to spread in the United States, anyone traveling to South America, Central America or the Caribbean should be aware they face a chance of contracting Zika.

    For a full list of questions and information about Zika related travel plans, see the latest from the CDC.

  • Why are we seeing more cases of Zika and microcephaly in the Western Hemisphere than in other parts of the world?

    Zika has been present in equatorial Africa and the Asian Pacific for over 50 years, where the virus has been living in a relatively symbiotic relationship with the local populations. However, when viruses are introduced to new populations that are not predisposed to having the natural immune defenses needed to protect against the virus — such as in Brazil and the Western Hemisphere — they spread rapidly. This is generally what happens with an outbreak.

    “Viruses generally exist within a niche host community, and they evolve within that niche over time. From an evolutionary perspective, it doesn’t benefit the virus to kill its host, or even make the host seriously ill. Whenever you hear of a situation where people are getting really, really sick, those people are not part of the natural host population for whatever virus is making them sick. Therefore, when a virus is introduced to a new population — as Zika was in Brazil and the Western Hemisphere — we end up seeing explosive growth in the number of adverse cases.”

  • What are the symptoms and side effects?

    Zika virus does not generally have many symptoms, so most people infected with the virus will not even know they have been infected. However, 1 in 5 people may develop symptoms including fever, rash, joint pain, or red eyes. Some people may also experience muscle pain and headache. Symptoms from Zika virus normally last from 2 to 7 days.

    If you experience these symptoms, or have recently traveled, you should consult your doctor and tell your health care provider when and where you traveled. Members of at risk populations, such as pregnant women, women who are considering becoming pregnant, or who have a chance of becoming pregnant, and males who are sexually active, should take extra precautions to protect themselves from contact with mosquitos, and practice safe sex.

    After becoming infected by Zika virus, it is believed that people are able to spread the virus over the course of the first two weeks. Therefore, it is important to think about the public health and limit your exposure to mosquitos for several weeks after travel to countries on the Centers for Disease Control and Prevention (CDC) watch list.

  • How do you become infected with Zika?

    The most common method of transmission is through a mosquito bite. However, Zika can also spread through sexual transmission.

  • Is there a test for Zika?

    While there are currently no quick diagnostic tests currently available for the Zika virus, scientists are working feverishly to develop these methods. In the meantime, it can be detected through blood tests, which often take a couple days to return. Visit the CDC for more information.

  • Where does Zika come from?

    Zika originated in the Zika forests of Uganda in 1947. From Uganda, the virus spread to Micronesia in Southeast Asia. In 2007, the Asian strain is believed to have made its way across the South Pacific — a region of the world that also contained dengue and chickagunya. This strain is believed to be responsible for a 2013 outbreak in French Polynesia — where evidence of Guillain-Barré Synrdome first appeared.

    The recent Zika virus outbreak was first realized in Brazil in May 2015, with the heaviest concentration of Zika related microcephaly cases appearing in the northeastern region of the country. Since then, the virus has spread throughout South and Central America, the Caribbean and Puerto Rico. It is also present in the continental U.S. and expected to spread throughout the

  • What is Microcephaly?

    Microcephaly is a congenital birth defect that causes children to be born with abnormally small heads and underdeveloped brains. It is believed to be caused by Zika as well as a number of other factors, including infections of the fetus, rubella, and other diseases.

    Under normal conditions microcephaly occurs in 1 in approximately 5,000 to 10,000 births.

    However, in recent years there has been a dramatic increase in the number of confirmed Zika related cases of microcephaly. A vast majority of these cases occurred in northeastern Brazil, and researchers are searching for answers to why there is a higher than normal concentration of microcephaly in this region.

    There is currently no known treatment for microcephaly.

    For more information, the World Health Organization has a wonderful fact sheet on microcephaly.
