First case of Zika virus confirmed in Oklahoma

OKLAHOMA - The Oklahoma State Department of Health says the first case of Zika virus has been confirmed in Oklahoma.

State officials say two residents acquired the virus during international travel.

Zika virus is transmitted to people primarily through the bite of an infected Aedes aegypti mosquito, though there also have been reports of transmission through sexual contact or from mother to unborn child.

The disease can cause fever, rash, muscle and joint aches and red eyes.

These symptoms typically last several days to a week, and hospitalizations are rare.

Health officials say most people exposed to Zika virus won’t develop any symptoms at all.

The most significant health threat is for pregnant women because Zika virus infections have been linked to the birth defect microcephaly, miscarriage, and other poor birth outcomes in some women infected during their pregnancy.

The CDC and OSDH advise pregnant women to delay travel to foreign countries and U.S. territories where Zika virus is being transmitted.

“We are recommending that individuals returning from travel to areas where Zika virus has been identified to consult with their physician if they exhibit any of the symptoms associated with the disease, particularly women who are pregnant,” said Oklahoma State Epidemiologist Dr. Kristy Bradley. “Fortunately, for Oklahoma, the Aedes aegypti mosquito is not commonly found in the state.”

OSDH Acute Disease Service epidemiologists are working directly with health care providers statewide to determine if their patients meet the criteria for testing and arrange for testing to be conducted.

The virus can also lead to guillain-barre syndrome, which can attack the nervous system.

Guillain-barre syndrome can affect people of all ages.

"That can cause muscle weakness and fatigue and if serious it can cause problems with our breathing ability, which could result in hospitalization and even death," said Laurence Burnsed with the Oklahoma State Department of Health.

There is no vaccine, preventative medication, or specific treatment drug available for Zika virus.

Oklahomans traveling to Zika-affected areas over the upcoming Spring Break should take extra precautions to protect against mosquito bites.

To prevent the spread of the disease, people traveling to those areas should carefully follow steps to avoid mosquito bites while there and for seven days after returning home.

Mosquito exposure prevention tips while traveling to affected areas include:

  • Use air conditioning or window/door screens to keep mosquitoes outside. If you are not able to protect yourself from mosquitoes inside your home or hotel, sleep under a mosquito bed net.
  • Use mosquito repellents according to instructions.
  • If weather permits, wear long-sleeved shirts and long pants.
  • Help reduce the number of mosquitoes outside your home, hotel room or workplace by emptying standing water from containers, such as flowerpots or buckets.
