Is Zika virus RNA or DNA?
Zika virus is a single-stranded RNA virus of the Flaviviridae family, genus Flavivirus.
How does Zika virus look like?
The rash associated with the Zika virus is a combination of flat blotches (macules) and raised tiny reddish bumps (papules). The technical name for the rash is “maculopapular.” It’s often itchy. The Zika virus is spread by the bite of an infected Aedes mosquito.
How does Zika virus reproduce?
Zika virus is transmitted primarily through the bite of an infected female mosquito. Mosquitoes become infected when they bite a person who is infected with the virus. The virus then replicates and spreads within the mosquito so that when the infected mosquito bites again, the virus is spread to another person.
Where does Zika virus come from?
Zika, a flavivirus transmitted mainly by mosquitos in the genus Aedes, was discovered in 1947 in Uganda. From the 1960s to 1980s, human infections were found across Africa and Asia, typically accompanied by mild illness.
Is Zika virus a pandemic?
Epidemic and pandemic are primarily different in terms of spread of contagious, infectious, or viral illness. An epidemic is limited to one specific region while a pandemic has a worldwide spread. Zika virus is an epidemic which was reported in Brazil in Feb., 2016.
Is Zika still around 2020?
As of January 2020, there are no areas with a current Zika outbreak. If you are trying to get pregnant, or your partner is trying to get pregnant, then you may want to reconsider travel because of the virus’s link to birth defects and complications.

How does Zika attack the body?
The Zika virus uses a type of RNA to interfere with human proteins that would restrict its ability to multiply. Certain mosquitoes can carry pathogens that are able to infect humans, including Zika and dengue viruses.
What disease does Zika cause?
Zika fever, also known as Zika virus disease or simply Zika, is an infectious disease caused by the Zika virus. Most cases have no symptoms, but when present they are usually mild and can resemble dengue fever. Symptoms may include fever, red eyes, joint pain, headache, and a maculopapular rash.

- Prevent getting Zika infection through sex by using condoms from start to finish every time you have sex (oral, vaginal, or anal) or by not having sex during your pregnancy.
Is the Zika virus curable or treatable?
Zika virus disease is usually relatively mild. Currently, there is no cure or specific treatment for Zika virus. Treatment aims to ease symptoms and reduce the risk of complications while the person recovers.
Is Zika easily diagnosed?
A diagnosis of Zika virus infection can only be confirmed by laboratory tests of blood or other body fluids, such as urine or semen.
How is Zika treated?
There is no specific treatment for infection with the Zika virus. To help relieve symptoms, get plenty of rest and drink plenty of fluids to prevent dehydration. The over-the-counter (OTC) medication acetaminophen (Tylenol, others) may help relieve joint pain and fever.
What are two effects of having Zika?
The most common symptoms of Zika are fever, rash, headache, joint pain, red eyes, and muscle pain. Zika is spread mostly by the bite of an infected mosquito. Prevent Zika by avoiding mosquito bites. Zika can cause birth defects and is linked to Guillain-Barré syndrome.
How serious is the Zika virus?
Zika virus disease is generally mild, and severe disease requiring hospitalization and deaths are uncommon. Zika infection during pregnancy can cause serious birth defects and is associated with other pregnancy problems.
