From a pregnant women to her fetus
Blood transfusions (likely but not confirmed)
What are the symptoms of Zika infection?
Most people infected with Zika won't have any symptoms
at all or will only have mild symptoms. Therefore, most
people do not seek medical attention or are not sick
enough to go to the hospital. Symptoms can last up to a
week. Once a person has been infected with Zika, they
are likely immune from future Zika infections. The most
common symptoms of Zika are:
Zika During Pregnancy
Zika infection during pregnancy can cause severe birth
defects of an infant's brain called
microcephaly. Zika is also linked to other problems
such as miscarriage and stillbirth. Please see
Special Report: Newborn Microcephaly: How Often is it
Diagnosed in LAC? for a five-year review of county
hospitalizations with a microcephaly diagnosis.
Numerous countries that have experienced Zika outbreaks have also reported increases in people who have
Guillain-Barré syndrome, an uncommon sickness of the nervous system. However, only a small percentage of people with recent Zika virus infection get Guillain-Barré syndrome.
Protect Yourself and
There is no vaccine to prevent Zika. During the first week of infection, Zika virus can be found in the blood and passed from an infected person to another mosquito through mosquito bites. An infected mosquito can then spread the virus to other people. The best way to prevent Zika, and other diseases that spread by mosquitoes, is to protect yourself and your family from mosquito bites while you travel to areas where Zika is spreading.
Also, continue to avoid mosquito bites for at least
three weeks after you return to LA County. Please see
Special Report: Zika Community Engagements Meetings

Use Environmental Protection Agency (EPA)-registered insect repellents with one of the following active ingredients:
DEET, DEET, picaridin, IR3535, oil of lemon eucalyptus or para-menthane-diol,
See FLYER for more tips.
Do not use insect repellents on children younger than 2 months old.
Do not use products containing oil of lemon eucalyptus or para-menthane-diol
on children younger than 3 years old.
When outside, especially when you are in areas with
mosquitoes, wear long-sleeved shirts and pants.
Stay in places with air conditioning and window and door
screens to keep mosquitoes outside.
Plan for Travel
Outbreaks of Zika are currently occurring in many
countries and territories. Check the
LOCATIONS before you travel.
Include a mosquito protection plan both before and after
Review the CDC's travel
RECOMMENDATIONS for areas with risk of Zika.
Protect Yourself During
Zika can spread through
unprotected sex from a person who is infected to his or
her partner. Not having sex can eliminate the risk of
getting Zika from sex. Pregnant couples should use
condoms or abstain from sex for the duration of the
pregnancy. Men should use condoms for 3 months from
diagnosis of Zika infection or travel to areas where
Zika is spreading. Women should take sexual precautions
for 8 weeks after diagnosis or travel.
Diagnosis of Zika is based on a person’s recent travel history, symptoms, and test results. A blood and/or urine test can confirm a Zika infection.
There is no specific medicine or vaccine for Zika virus.
The only course is to treat the symptoms:
Get plenty of rest.
Drink fluids to prevent dehydration.
medicine such as acetaminophen to reduce fever and pain.
Do not take aspirin or other non-steroidal anti-inflammatory drugs (NSAIDs).
If you are taking medication for another health condition, talk to your healthcare provider before taking additional medication.
See your doctor if you develop symptoms
of Zika and have recently traveled to an area with risk of Zika or if you had sex without a condom with a person who lives in or traveled to an area with risk of Zika. Be sure to tell your doctor where you traveled and when you returned. A blood or urine test can confirm a Zika
infection. Testing is especially important if you are
pregnant or the partner of a pregnant woman.
