Most Susceptible Hosts• People who do NOT protect themselves (from vectors and/or from STDs)• People who are more prone to mosquito bites• People who travel to or reside in places with autochthonous transmission• All age groups are at risk for Zika virus infection;
• in Yap Island outbreak, attack rate for symptomatic Zika virus disease among children (<19 years of age) was lower than for adults
• Fetuses are the most at risk for complications, though vertical transmission risk is ~10%• Among adults, those with underlying disease are at highest risk for complications

TransmissionTransmission
� Zika can be spread through:� Mosquito “bites”
� Female Mosquito to her eggs
� Sexually between Mosquitos
� Pregnant woman to her fetus � Sex with an infected person� Blood transfusion � Lab accident� Possibly via organ and tissue
transplant, fertility treatment, and breastfeeding
� Animal to animal via bites, sex?
Anyone who lives in or travels to an area with Zika and has not already been infected with Zika virus can get it.

July 2017, CDC: Interim Guidance for HCW caring for Pregnant women with possible Zika exposure
1. All pregnant women in U.S.A. and its territories should be asked about possible Zika virus exposure before and during current pregnancy, at every prenatal care visit.
2. Pregnant women with recent possible Zika virus exposure and symptoms† of Zika virus disease should be tested to diagnose cause of their symptoms.
3. Asymptomatic pregnant women with ongoing possible Zika virus exposure§ offer Zika virus Nucleic acid-based test (NAT) testing 3- times during pregnancy.
4. Asymptomatic pregnant women with recent¶ possible Zika virus exposure (e.g. travel or sexual exposure) but without ongoing possible exposure are not routinely recommended to have Zika virus testing.
5. Pregnant women with recent possible Zika virus exposure and with fetus with prenatal ultrasound findings c/w congenital Zika virus syndrome should receive Zika virus testing to assist in establishing cause of birth defects. Use both NAT and IgM tests.
6. Comprehensive approach to testing placental and fetal tissues has been updated.
7. Zika virus IgM testing as part of preconception counseling to establish baseline IgM for nonpregnant women with ongoing possible Zika virus exposure is notwarranted b/c Zika virus IgM testing is no longer routinely recommended for asymptomatic pregnant women with ongoing possible Zika virus exposure.

� A 45-year-old healthy outpatient with a fever that had started 5 days previously; diffuse joint pain, myalgia, headache, and diarrhea. Had been in La Martinique islands from 21 December 2015 to 1 January 2016. On his return he complained of a recent mild throbbing, squeezing mediothoracic pain without any spread to other parts of his body and no dyspnea.
� Initial examination revealed a body temperature of 39°C, bilateral conjunctivitis, and hand edema but no skin rash. His blood pressure was normal, heart rate was 95 bpm; no sign of cardiac failure, no abnormal heart sounds.
� Myocarditis diagnosed, based on an ST-segment elevation in anteroseptal region, electrocardiogram associated with increase in troponin I level (0.49 µg/L, normal <0.04 µg /L) and creatine phosphokinase (CPK) level (213 UI/L, normal <200 UI/L).

Treatment of Zika
� There is no specific licensed medicine or vaccine for Zika virus.
� Treat the symptoms.– Plenty of rest.
– Fluids to prevent dehydration.– Over-the-counter meds e.g. acetaminophen to reduce fever & pain
– Avoid aspirin & other NSAIDS until dengue can be ruled out to reduce risk of bleeding
– Avoid secondary infections
– Assure patient’s current meds do interfere &/or are not affected by use of any additional meds
� Infants with Zika Congenital Symptoms: – Manage symptoms
