Pathological Profile

Zika Fever

Zika fever is a viral illness spread primarily by Aedes mosquitoes, especially Aedes aegypti. While symptoms are usually mild, Zika infection during pregnancy can cause severe birth defects, including microcephaly.

Symptom Timeline

Pathology Progression Phases

Phase 1: Incubation (Days 3-7)

Infection Window

Pathogen replicates inside body tissue (e.g. liver for malaria, blood cells for dengue). Usually asymptomatic during this window.

Phase 2: Acute Fever (Days 8-12)

Clinical Manifestation

Sudden onset of high fever, severe headache, muscle joints pain, and shivering. Highly infectious to feeding vectors.

Phase 3: Resolution (Days 13+)

Convalescence or Crisis

Antibodies clear the pathogen. If complications develop (e.g. plasma leakage, hemorrhagic shock), intensive care is required.

Clinical Summary

Zika virus is a single-stranded RNA virus of the family Flaviviridae. Most people infected with Zika virus do not develop symptoms. However, when symptoms do occur, they typically begin 3 to 14 days after exposure and resolve within a week.

Pregnancy Implications

Congenital Zika Syndrome is a unique pattern of birth defects in fetuses and infants infected with Zika virus during pregnancy. It is marked by severe microcephaly, brain tissue damage, eye damage, and congenital joint contractures.

Diagnostic Symptoms Checklist

  • Mild fever
  • Maculopapular rash
  • Conjunctivitis (red eyes)
  • Joint and muscle pain
  • Headache

Risk Factors

  • •Pregnant women and women planning pregnancy.
  • •Unprotected sex with infected individuals.

Treatment Protocol

There is no specific antiviral treatment or vaccine for Zika. Treatment is supportive, focusing on rest, hydration, and acetaminophen for fever and pain. Avoid aspirin or NSAIDs until Dengue is ruled out.

Frequently Asked Questions

Can Zika be transmitted sexually?

Yes, Zika virus can be passed through sex from an infected person to their partners, even if the infected person does not have symptoms.
