Doctor's Notes on Zika Virus
Zika virus (Flavivirus) is a viral pathogen that causes Zika fever. The virus spreads to humans by mosquito bites or from human to human by sexual contact and can be a cause of severe birth defects. Signs and symptoms of Zika fever include
The signs and symptoms usually resolve on their own. However, the virus can remain viable for many months in the body. For example, Zika virus can be found in the eyes and the semen for many months even if symptoms have resolved. It can infect the fetus at almost any time if the mother becomes infected during pregnancy, with microcephaly (small head) and other birth defects such as delayed development, intellectual disability, and neurological abnormalities as possible outcomes of the infection for the fetus.
Because the virus remains viable in the body even months after symptoms resolve, the infected person may still transmit the Zika viruses by sexual contact to others; over time, however, the risk of infection decreases. Researchers are trying to determine how long people are infective to others.
What Are the Treatments for Zika Virus Infection?
The CDC currently states (2021) that no specific medicine or vaccine is available for Zika virus. However, the CDC lists six supportive care measures for this infection as follows:
- Treat symptoms.
- Drink fluids to avoid dehydration.
- Take medicine like acetaminophen to reduce fever and pain.
- Do not take aspirin or other NSAIDs until the disease termed dengue is ruled out to reduce the risk of bleeding.
- Consult with your doctor about medications you currently take or are planning to take.

Polymerase Chain Reaction (PCR) TestPCR (polymerase chain reaction) is technique in molecular genetics that analyzes short sequences of DNA or RNA. PCR is used to help doctors diagnose HIV, viruses, and fungi in patients. RT-PCR is a test used to detect and measure RNA -- as of June 2020, this is the standard test to diagnose the presence of the SARS CoV-2 coronavirus responsible for the deadly COVID-19 pandemic.
Pregnancy PlanningPregnancy planning is important to help prevent exposure of the mother and fetus to potentially harmful medications and substances during the early days, and throughout the pregnancy. Nutritional planning, prevention of birth defects, conditions such as high blood pressure, heart disease, diabetes, and kidney disease need careful monitoring. Gestational diabetes, preeclampsia, and pregnancy-induced hypertension are conditions that may arise during pregnancy. Immunizations, inherited disorders, exercise, air travel, intercourse, and birth control are important factors to consider when planning a pregnancy.
