    Zika: How to protect yourself from the mosquito-borne virus

    Pregnant women should not travel to affected areas
    Children under 3 should not use certain types of insect repellent
    CDC: An outbreak in the U.S. would “likely be limited.’’

    As the mosquito-borne Zika virus tears through Latin America and the
    Caribbean, health officials in the United States say it’s only a matter
    of time before someone is affected here.

    But Anne Schuchat, principal deputy director for the Centers for Disease
    Control and Prevention, said Thursday that “outbreaks of Zika in the
    continental U.S. will likely be limited.”

    The mosquito-borne disease has raged in South America and other regions
    for months. The World Health Organization said it continues to spread.
    While the mosquito that carries the virus, Aedes aegypti, is common in
    South Florida, Schuchat said several factors in the United States work
    in our favor: U.S. urban areas are less densely populated,
    air-conditioning is more widespread and mosquito control efforts are
    generally stronger.

    “We are very aggressive when it comes to mosquito control,” said Beth
    Ranson, of the Florida Keys Mosquito Control District. The district has
    been working with Oxitec, a biotech company, on developing a genetically
    modified male mosquito to mate with female mosquitoes, which would
    produce offspring that won’t make it to adulthood. The company has said
    trials conducted in Brazil have reduced the Aedes aegypti population by
    90 percent. The Food and Drug Administration is examining the proposal.

    The World Health Organization said Thursday possible links of Zika to
    neurological syndromes that can cause paralysis changed Zika from “a
    mild threat to one of alarming proportions.’’

    Since 2015, 31 travel-associated Zika cases have been detected in 11
    U.S. states, Schuchat said. Earlier this month, the Florida Health
    Department confirmed three travel-related cases in Florida. Two were in
    Miami-Dade from people who brought the disease back from Colombia. The
    third was in Hillsborough County, where a person contracted the virus in

    The disease cannot be transmitted by routine human contact. Rather, it
    is transmitted when an infested mosquito bites a human, and then another
    mosquito bites the infected person. The main risk is to pregnant women,
    as the disease has been linked in Brazil to about 4,000 cases of
    microcephaly, a rare birth defect that causes babies to be born with
    smaller brains. There has been one case where a wife contracted the
    disease from her husband during sexual intercourse, Schuchat said.

    The CDC has issued a travel alert for more than 20 countries including
    Brazil, Colombia, the Dominican Republic, El Salvador, French Guiana,
    Guatemala, Haiti, Honduras, Martinique, Mexico, Panama, Paraguay,
    Suriname and Venezuela. The virus also has been found in Puerto Rico and
    the U.S. Virgin Islands.

    The reason for the concern: the mosquito that transmits the Zika virus
    is linked to the same mosquito that brought cases of tropical diseases
    chikungunya and dengue to the United States, particularly to South Florida.

    “I am willing to bet money we will see some locally transmitted cases
    [of Zika],” said Amy Vittor, an assistant professor in the University of
    Florida’s Department of Medicine and Emerging Pathogens.

    Additionally, the Aedes aegypti mosquito multiplies exponentially in
    small levels of standing water.

    “It only takes a tablespoon of water to produce 300 mosquitoes,’’ said
    Ranson of the Florida Keys Mosquito Control District.

    Here, then, is more information about Zika and steps you can take to
    minimize your risk of contracting it.


    Only one out of five people who contract the disease will show symptoms,
    according to the CDC. Symptoms include fever, rash, joint pain and
    conjunctivitis (red eye). That makes it harder to know if someone is
    infected, Schuchat said.

    “Those who do get sick usually have very mild symptoms,” Schuchat said.

    The incubation period is usually three to 12 days, meaning if you were
    exposed to the virus, you would get it during this period.

    There is no vaccine or medications to treat the virus.


    Pregnant women — or women who are planning to become pregnant — are at
    the greatest risk. The risk is not so much to themselves, but to their
    baby, who can be born with the rare birth defect that causes the small
    brains. The CDC strongly recommends that pregnant women in any
    trimester, especially the first trimester, not travel to affected areas.

    “If you are pregnant we recommend you consider postponing travel to a
    region with ongoing Zika virus transmission,” said Schuchat.

    If you have visited one of the countries with the virus, and develop a
    fever, rash, joint pain or red eyes within two weeks after traveling to
    that country, see your doctor immediately, the CDC says. A blood test
    can determine if you’re carrying the virus.

    The CDC said this week that U.S. doctors should test newborns who show
    signs of the Zika virus, especially in states such as Florida, where
    mosquitoes are prevalent.

    Pregnant women and women who are breastfeeding can use insect repellent
    with one of the following active ingredients: DEET and Picaridin, found
    in such products as Off!, Cutter and Skin So Soft Bug Guard Plus. These
    are EPA-registered insect repellents. The CDC does not recommend using
    the following non-registered repellents: Citronella oil, cedar oil,
    geranium oil, peppermint and peppermint oil, pure oil of lemon
    eucalyptus and soybean oil.

    The CDC does not know whether a future pregnancy would be at risk if a
    woman is bitten by an infected mosquito now and gets pregnant later.

    The American College of Obstetricians and Gynecologists says a small
    amount of the Zika virus found in breast milk is “unlikely to be
    harmful’’ to the baby.


    Most insect repellant can be used on children, according to the CDC,
    with a few caveats.

    For one, never apply insect repellent to children younger than 2 months
    old, warns the American Academy of Pediatrics.

    For children 3 and under, do not use products containing oil of lemon
    eucalyptus, found in many repellents, the CDC says.

    In terms of applying repellent on children, here are a few guidelines
    from the American Academy of Pediatrics:

    ? Never spray repellent directly onto a child’s face. Instead, spray a
    little on your hands and rub it onto a child’s face.

    ? Avoid spraying repellent on cuts, wounds or irritated skin.

    ? Always wash a child’s skin with soap and water after they come inside.

    ? Do not use products that combine DEET with sunscreen, as you run the
    risk of overexposing your child to the repellent.

    ? Cover cribs, strollers or baby carriers with mosquito netting.

    “Parents should always check with their pediatrician to see what works
    best for their child,” said Dr. Jefry Biehler, chairman of pediatrics at
    Nicklaus Children’s Hospital.


    If you’re traveling to an area that has the Zika virus, here are some
    key steps to take, according to the CDC:

    ? Choose a hotel or lodging with air-conditioning and screens on windows
    and doors;

    ? If you are sleeping outdoors, sleep under a mosquito net, preferably
    one treated with permethrin, an insecticide that kills mosquitoes. You
    can also buy permethrin-treated clothing, shoes and camping gear. But,
    do not spray permethrin onto your skin;

    ? Travelers to affected areas should monitor for symptoms or illness
    upon return.


    Local governments are stepping up mosquito control efforts. And the
    Florida Department of Health is closely monitoring mosquitoes in South
    Florida to determine whether the disease has hit the local population.

    But, officials say, individuals can help prevent the spread of the
    disease by taking these steps:

    ? Clear and drain standing water. Mosquitoes breed in standing water.

    ? When outside, wear light-colored long-sleeve shirts and long pants.

    ? Stay in air-conditioning and keep doors and windows without screens
    closed. This type of mosquito likes to live indoors as well as outdoors.

    “The best way to prevent Zika is by not getting bitten,’’ Biehler said.
    “But if your child gets bitten in South Florida, don’t panic.’’
