Zika Virus Infection

Zika virus (ZIKV) is a mosquito-borne flavivirus primarily transmitted by Aedes aegypti and Aedes albopictus mosquitoes. While often asymptomatic or causing mild, self-limiting illness, infection during pregnancy is associated with severe congenital anomalies, including microcephaly and other neurological impairments.

Zika is caused by a single-stranded RNA virus in the Flaviviridae family. Transmission occurs via the bite of infected mosquitoes, sexual contact, blood transfusion, and vertical (mother-to-child) transmission.

The virus enters human cells through receptors such as AXL. It targets neural progenitor cells, impairing their proliferation and inducing apoptosis, which leads to the structural brain defects seen in congenital Zika syndrome. In adults, it induces a transient viremia triggering a cytokine-mediated inflammatory response.

Outbreaks have occurred globally, notably in the Americas, Southeast Asia, and the Pacific Islands. It affects all ages and genders equally, though pregnant individuals are the highest risk group for severe outcomes.

• Residence in or travel to endemic areas
• Unprotected sexual contact with infected partners
• Occupational exposure to mosquito habitats
• Lack of physical barriers (mosquito nets, screens)

A. Early Symptoms

• Mild fever


• Fatigue B. Common Symptoms


• Maculopapular rash


• Arthralgia (small joints)


• Conjunctivitis


• Myalgia C. Advanced Symptoms


• Guillain-Barré Syndrome (GBS)


• Encephalitis D. Emergency Symptoms


• Sudden weakness/numbness (signs of GBS)


• High fever with neurological deficits

• Non-purulent conjunctivitis
• Maculopapular, pruritic rash
• Mild joint swelling
• Possible hyperreflexia or muscle weakness (if neurological complications arise)

A. Clinical Assessment: History of travel and symptom cluster.
B. Laboratory Testing: RT-PCR for viral RNA; IgM ELISA for antibodies.
C. Imaging Studies: Fetal ultrasound for pregnant patients.
D. Functional Tests: Nerve conduction studies for GBS.
E. Biopsy Findings: N/A.
F. Genetic Testing: N/A.
G. Differential Diagnosis: Dengue, Chikungunya, Malaria.

Test Name: Zika Virus Nucleic Acid Test (NAT)
Type: Blood or Urine Test
Purpose: Detect active infection
Expected Findings: Positive viral RNA
Interpretation: Confirms current Zika infection

• Fetal Ultrasound: Essential for pregnant patients to monitor head circumference and detect intracranial calcifications.

Dengue fever (more severe hemorrhage), Chikungunya (severe persistent arthritis), and Malaria (high cyclic fever).

Congenital Zika syndrome, Guillain-Barré syndrome, myelitis.

A. Lifestyle Modifications: Rest, increased fluid intake.
B. Preventive Measures: Mosquito repellent (DEET), bed nets, condom use.
C. Medical Treatment: Acetaminophen (avoid NSAIDs until dengue is ruled out to prevent bleeding).
D. Surgical/Interventional: Supportive only.
E. Rehabilitation: Physical therapy for GBS recovery.

Good for the general population (usually resolves in 1 week). Poor for fetuses with microcephaly.

Vector control, use of long-sleeved clothing, travel avoidance for pregnant women.
