According to the American organization CDC, the Zika virus can spread in any of these ways – 

  • Mosquito Bites – Zika virus is mainly transmitted to people by the bite of an infected Aedes species mosquito (Ae aegypti and Ae albopictus).  These are the same mosquitoes that spread the dengue and chikungunya viruses. 
  • From mother to fetus – Pregnant women already infected with Zika virus can pass the virus to the fetus during pregnancy or at birth.
  • Through sex – Zika infection can be transmitted from an infected person to an uninfected partner during sex, even if the infected person does not have symptoms at the time.  Therefore, it is better to follow all the rules of safe sex, such as using a condom.
  • Via blood transfusion – There have been several reports of Zika transmission in Brazil due to possible blood transfusion.

When to see a Doctor? 

Contact your doctor if you or a family member suspects you of contracting Zika virus, especially if you have recently been to an outbreak.  The Centers for Disease Control and Prevention conducts blood tests to detect Zika virus and other similar diseases, such as dengue and chikungunya, which are transmitted by the bite of the same type of mosquito. 

What Causes of Zika Virus? 

The Zika virus is mainly transmitted through the bite of an infected Aedes mosquito.  This mosquito is found all over the world.  It was first identified in 1947 in the Zika Valley of Africa, but since then cases of infection have been reported in South and Southeast Asia, the Pacific Islands and the American continents.  When a mosquito bites an infected person, the virus passes inside the mosquito.  And then the virus enters the blood of anyone the infected mosquito bites. There have also been cases of transmission of infection through sexual intercourse and blood transfusion.

  • Prevent Mosquitoes Growing Nearby – Mosquitoes that spread Zika virus live in or near homes.  They thrive in water stored in animal food utensils, pots or used tires etc.  Prevent mosquito breeding to reduce the number of mosquitoes. 

Zika Virus infection through Blood transfusion 

Pre-donation tests now include testing for Zika virus.  Where Zika virus infection has not spread, to reduce the risk of transmission, the US Food and Drug Administration recommends not donating blood for four weeks in the following circumstances:

The doctor can take the details of the ailments and travels you have had so far.  Tell the doctor about your international travels, such as the countries you have visited, the date you have had sex with, and if you have been to any places where mosquitoes have lived. Ask your doctor about facilities available in your area to test for Zika or similar diseases, such as dengue or chikungunya.  These diseases are caused by the bite of a mosquito of the same species. If a pregnant woman has recently been to a Zika-infected place and is currently showing no symptoms of Zika virus, she can be tested two to 12 weeks after her return. 

If the test is confirming the presence of Zika virus or not, or if nothing is being detected, then the doctor may do the following tests: 

  • Ultrasound to check for microcephaly or other abnormalities of the fetal brain 
  • Testing for Zika virus by inserting a needle into a pregnant woman’s uterus by removing amniotic fluid (Amniocentesis) 

Treatment for Zika Virus

There is currently no treatment available for infection with the Zika virus.  Generally, the treatment of Zika is only symptomatic.  As a treatment for Zika virus, the patient is advised to rest and drink fluids and is given acetaminophen and ibuprofen based medicines to relieve joint pain and fever. 

There is no vaccine yet to protect against the Zika virus. 

Zika Virus Complications: What complications can arise from the Zika virus? 


Zika virus infection during pregnancy can lead to miscarriage and microcephaly (smaller than normal brain size). 

Zika virus can cause congenital Zika syndrome, which can lead to the following disorders

  • Severe microcephaly in which the head becomes slightly flattened
  • Damage to the brain and loss of brain cells 
  • Damage to the eyes 
  • Problems in the joints that make walking difficult 
  • Decreased physical activity of the child due to excessive muscle tension after birth
