Read Disclaimer & Fine Print

Zika virus disease is a nationally notifiable condition:

Healthcare providers should report suspected Zika virus disease cases to their state, local, or territorial health department, who will report to the CDC.

WHAT IS IT?

The Zika virus (ZIKV) was first discovered in 1947, but has only become a global public health threat in the last decade with marked geographic spread in the last 5 years
The Zika virus is named after the Zika forest in Uganda where it was first found, is a Flavivirus and is related to similar viruses such as dengue, West Nile and Japanese encephalitis
The infectious viral particle (virion) is primarily composed of a single strand of RNA which is released into the infected cell’s cytoplasm, overtakes the infected cell’s genetic and cellular machinery, leading to replication and release of additional Zika virus
ZIKV, typical for a Flavirus, is predominantly spread via mosquito vectors, however transmission via blood transfusion and sexual contact can occur

KEY POINTS:

Clinical symptoms appear 3 to 14 days after a mosquito bite and should resolve within 2 to 7 days
Most people will be asymptomatic
20% will have typical viral signs and symptoms, usually of a mild nature
- Fever
- Maculopaular rash
- Conjunctivitis
- Arthralgias
- Headache
Management is that of typical viral illness and includes:
- Rest
- Antipyretics
  - Note: current drug labels state that NSAIDs should not be used by pregnant women in their third trimester of pregnancy because of the risk of premature closure of the ductus arteriosus in the fetus
- Nutrition and adequate fluids
- Monitor for signs and symptoms of severe infection such as coagulopathies and organ damage – ICU care is rare but any concern should be escalated
- Guillain-Barré syndrome, an autoimmune neurological disorder, has been reported and while uncommon should generate a referral for diagnosis and management
