Zika virus is a RNA virus belonging to filovirus family and
transmitted by Aedes mosquitoes.
Its maternal-fetal transmission and anecdotal reports of sexual
transmission have been reported.
Aedes mosquitoes usually bite during the daytime and breed in
standing water so prevention is similar to dengue fever.
It’s a predominant mild or asymptomatic dengue like disease
without any hemorrhagic tendencies. Symptoms occur in just 20-25% of patients
with low case fatality rates. . It causes acute onset low grade fever with
multiple small joint pain, muscle ache, eye pain, prostration and maculopapular
rash and usually present 2 to 12 days after mosquito bite.
Recent reports suggests its association with fetal microcephaly
and intra cranial calcification which requires antenatal serial Ultrasonography
and biochemical evaluation in suspected cases
Treatment is bed rest and supportive care.
Similar to dengue aspirin should be avoided and hematocrit and
pulse pressure needs to be monitored.
