Zika Virus Fact Sheet



What is Zika virus?​

Zika is a type of virus spread by the bite of infected Aedes species mosquitoes. Aedes species (present in Maryland) also spread dengue and chikungunya viruses.


What are the symptoms of Zika infection?

Many people infected with Zika virus do not have symptoms or only get mild symptoms. 

Symptoms last for several days to a week. Hospitalizations and deaths from Zika infection are rare.

Zika virus in babies can cause microcephaly (where the baby’s head is smaller than expected) and other birth defects.


 How is Zika virus spread?

  • Mosquito: Zika virus is primarily spread through the bite of infected Aedes species mosquitoes.
  • Pregnancy: Zika virus can be spread from an infected pregnant woman to her fetus during pregnancy or around the time of birth.
