Is there a treatment for the Zika virus?
There is no specific medicine or vaccine for Zika virus.
How is Zika treated or cured?
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.
How did the Zika virus stop?
Instead, Zika cases have plummeted in Latin America and the Caribbean, where the virus raged over the past 2 years, and much of the population is now immune to it. That, in turn, means fewer infected people entering the United States, reducing the chances of mosquitoes spreading the virus to susceptible people.
Is there a vaccine for Zika virus yet?
Although Zika virus (ZIKV) infection is typically self-limiting, other associated complications such as congenital birth defects and the Guillain–Barré syndrome are well described. There are no approved vaccines against ZIKV infection.
Can you get a vaccine for Zika virus?
There is currently no vaccine to prevent Zika and no medicine to treat it. The best protection is through preventing mosquito bites and avoiding regions with the virus. While Zika's symptoms are generally mild, pregnant mothers and their unborn child have the greatest risk.

If you are pregnant and at risk of Zika virus infection, your doctor may also recommend one of the following procedures: Amniocentesis, which involves inserting a hollow needle into the uterus to remove a sample of amniotic fluid (amniocentesis) to be tested for the Zika virus.
What test is used to test for Zika?
If your doctor suspects that you may have a Zika virus infection, he or she may recommend a blood or urine test to confirm the diagnosis. The blood or urine samples can also be used to test for other, similar mosquito-borne diseases.
Can you take ibuprofen for Zika?
If you're feeling ill after recent travel to an area where mosquito-borne illness is common, see your doctor. Don't take ibuprofen (Advil, Motrin IB, others), naproxen sodium (Aleve) or aspirin until your doctor has ruled out dengue fever. These medications can increase the risk of serious complications from dengue fever.

ZIKV Detect 2.0 IgM Capture ELISA - On May 23, 2019, FDA authorized marketing of the ZIKV Detect 2.0 IgM Capture ELISA to detect Zika virus immunoglobulin (IgM) antibodies in human blood. The ZIKV Detect 2.0 IgM Capture ELISA is the first Zika diagnostic test the FDA has allowed to be marketed in the U.S. FDA reviewed the data for the test through the De Novo premarket review pathway. Previously, tests for detecting Zika virus immunoglobulin (IgM) antibodies—including the ZIKV Detect 2.0 IgM Capture ELISA—had been authorized only for emergency use under the FDA’s Emergency Use Authorization (EUA) authority. For more information, see Serological assays below
What is the FDA's Emergency Use Authorization?
Under the FDA’s Emergency Use Authorization (EUA) mechanism, the agency can enable the use of an unapproved medical product, or the unapproved use of an approved medical product, during emergencies, when, among other circumstances, there are no adequate approved, and available alternatives. An EUA is an important mechanism that allows broader access to available medical products under specific circumstances.
How does Zika spread?
Zika virus is spread to people primarily through the bite of an infected Aedes species mosquito. Most people never know that they have been infected with the virus. It is estimated that four out of five people with Zika virus infections have no symptoms at all. When symptoms do occur, the most common symptoms are fever, rash, joint pain, and conjunctivitis (red eyes). Even in those who develop symptoms, the illness is usually mild, with symptoms lasting from several days to a week.
Why is it important to review the use of innovative strategies to help suppress the population of virus-carrying mosquitoe?
Reviewing the use of innovative strategies to help suppress the population of virus-carrying mosquitoes is one of many activities in which FDA is engaged to help mitigate the threat of vector-borne epidemics , such as Zika.
Can a pregnant woman have a baby with Zika?
It does not mean, however, that all women who have Zika virus infection during pregnancy will have babies with problems. As has been seen during the current Zika outbreak, some infected women have delivered babies that appear to be healthy. More: Zika and pregnancy, from CDC, and CDC updates guidance for infants born to mothers with possible Zika virus infection during pregnancy (October 19, 2017)
What is the cause of Zika?
Zika virus disease is caused by a virus transmitted primarily by Aedes mosquitoes, which are also responsible for the transmission of dengue and chikungunya viruses. Researchers have been conducting several studies to get closer to an effective vaccine for the Zika virus that can help curb its spread across the U.S. and around the globe.
How long does Zika last?
Symptoms of the virus are mild and last anywhere from two days to a week. They include fever, skin rashes, conjunctivitis (red eyes), muscle and joint pain, headache and malaise. Infections like dengue can also be a precursor to Zika.
When was Zika first detected?
Zika virus, which was first identified in 1947 in a rhesus monkey in Uganda, was initially detected in humans in 1952. It is primarily transmitted by mosquitoes — specifically, mosquitoes from the Aedes genus, which also transmit yellow fever, dengue and chikungunya, and there is no vaccine or medicine for it so far. Aedes mosquitoes usually bite during the day, peaking during early morning and late afternoon/evening. Sexual transmission of Zika virus is also possible. Other modes of transmission such as blood transfusion are currently being investigated.
Is Zika a disease?
The World Health Organization declared the mosquito-borne disease, which has spread across Latin American and Caribbean nations, an international health emergency on Feb. 1. Zika, which was previously known to cause only moderate cold and flu-like symptoms, is now causing multiple neurological disorders, as well as microcephaly in babies. Microcephaly is a condition that causes babies to be born with abnormally small heads.
Can you die from Zika?
It is rare for people to die from a Zika infection.
Can Zika extend past the brain?
A new research published in The BMJ last week revealed that health consequences of the Zika virus for infected newborns may extend past the brain.
Why is there no treatment for Zika?
There are no approved drugs or vaccines for Zika, mainly because scientists long assumed the virus was so benign that it wasn’t worth the resources required to investigate treatment. Zika has not been widely examined, and while some early research noted that the virus could infect brain cells, the connection between Zika and microcephaly—a severe neurological birth defect—is relatively new. Even now, many people who get infected will never know it, and if they start showing signs of infection, such as a rash, red eyes, fever or joint pain, doctors have little to offer other than advice to stay hydrated or take Tylenol as needed.
How to prevent Zika?
Cover up and use bug spray, for starters. Preventing mosquito bites is the best way to prevent Zika, and while that may seem obvious, it can take some work. If you’re in an area with disease-spreading mosquitoes, wear long-sleeved shirts and pants no matter how warm it is—mosquitoes are more infectious when the mercury rises. Then, according to the CDC, use insect repellents that contain one of the following ingredients: DEET (20% to 30% concentration is best, according to the CDC), picaridin, oil-of-lemon eucalyptus, para-menthane–diol or IR3535.
What do we still not know about Zika?
A lot more than we do know, that’s for certain. Doctors still don’t understand why some pregnant women infected with Zika give birth to babies with microcephaly while others do not. They also don’t know at which point during pregnancy the risk of infection is greatest and how likely it is for babies born with the disease to survive longer than a year. And while Zika definitely causes microcephaly, how the virus halts brain development remains unclear. Also unknown is what other brain problems the virus may cause. This is probably just the tip of the iceberg. The uncertainty is another cause of anxiety. “These are the kinds of things that we typically use to counsel women about infectious diseases in pregnancy and how it may affect them,” says the ob-gyn Beigi. “We have a scary outbreak, and we just don’t have that data.” Some of these questions may never yield a satisfying answer. “I think there is a significant likelihood we may not know why,” says the CDC’s Honein.
How many people travel to Zika every year?
With 40 million Americans traveling to Zika-a ffected countries every year, it’s only a matter of time before some local transmission of the virus occurs, say infectious-disease experts. It’s most likely to happen when an infected traveler returns to the U.S. and is bitten by a local mosquito that’s capable of spreading disease. It’s essentially every person’s responsibility, then, to make it harder for mosquitoes to spread the virus.
Where is Zika virus spreading?
A s the Zika virus continues to spread through the Americas —and with hundreds of imported cases here in the United States—here’s what every American needs to know about the virus and their risk.
Can you get Zika in your home state?
People living in Southern states and Hawaii—where the climate, geography and the presence of A. aegypti mosquitoes make eventual local transmission likely—are not currently at high risk of getting the virus in their home states, according to the CDC. “The one exception is that if their partner has been traveling to an area of Zika transmission, there is a risk of sexual transmission,” says Margaret Honein, chief of the CDC’s Birth Defects branch. Over time that risk may be enough to encourage U.S. women of childbearing age to consider using birth control.
Is the CDC a level 1 response?
It depends on where you live. The CDC has activated its Emergency Operations Center ( EOC) to a Level 1 response for Zika , something that’s happened only three other times: during Hurricane Katrina, the H1N1 flu outbreak and the Ebola crisis. In the EOC in Atlanta, scientists monitor cases of the virus, work on better diagnostics and run studies of pregnant women with Zika. Some progress has been made. The agency has sent better testing tools to state laboratories and recently concluded that the link between Zika and microcephaly—which had previously been suspected but not proved—is definite.
What are the symptoms of Zika?
Zika virus’ symptoms -- fever, conjunctivitis, joint pain and rash -- are short-lived, mild, and pale in comparison to its mosquito-borne brother, dengue or “breakbone” fever. Most people who contract Zika virus don’t even know that they have it, as only one in five become sick.
How many people contracted Zika in 2015?
Then, in 2015, Brazil experienced the widest outbreak of Zika virus to date, and up to 1.5 million people contracted the virus. Only then did scientists begin to connect the mild, mostly symptomless mosquito-borne disease to debilitating birth defects.
Did the National Institute of Allergy spend any time on Zika?
U.S. National Institute of Allergy and Infectious Diseases Director Anthony Fauci says agency researchers "have not really spent anything on Zika" prior to the current outbreak.
How to diagnose Zika?
A: To diagnose Zika, your doctor will ask you about recent travel and symptoms you may have, and collect blood or urine to test for Zika or similar viruses.
Why is there a Zika travel notice?
Because Zika can cause microcephaly and other severe birth defects, pregnant women should NOT travel to any area with a Zika outbreak (as indicated by red areas on Zika map).
How does Zika spread?
A: Zika virus disease is caused by the Zika virus, which is spread to people primarily through the bite of an infected mosquito ( Aedes aegypti and Aedes albopictus ). The illness is usually mild with symptoms lasting up to a week, and many people do not have symptoms or will have only mild symptoms. However, Zika virus infection during pregnancy can cause a serious birth defect called microcephaly and other severe brain defects.
How long does it take for Zika to be in blood?
Because Zika can generally be found in blood during approximately the first week of infection and can be passed to another person through mosquito bites, help prevent others from getting sick by strictly following steps to prevent mosquito bites during the first week of illness.
Can a person with Zika pass it to his or her sex partner?
Also, a person with Zika can pass it to his or her sex partners. We encourage people who have traveled to or live in places with risk of Zika to protect themselves by preventing mosquito bites and sexual transmission of Zika.
Can you travel to a place with Zika?
A: Yes. Travelers who go to places with Zika outbreaks (as indicated by red areas on Zika map) or with current or past spread of Zika (as indicated by purple areas on Zika map) might be at risk of infection with Zika. Pregnant women and couples trying to become pregnant within 3 months of travel should work with their healthcare providers to carefully consider the risks and possible consequences of travel. Zika travel notices are posted when there is an outbreak. Because Zika can cause microcephaly and other severe birth defects, pregnant women should NOT travel to any area with a Zika outbreak (as indicated by red areas on Zika map). Women trying to get pregnant should talk to their healthcare providers to carefully consider the risks and possible consequences of Zika infection before traveling to areas reporting current or past spread of Zika (as indicated by purple areas on Zika map), but no current outbreak. Those traveling to areas with Zika outbreaks or with current or past spread of Zika should take steps during and after they travel to prevent mosquito bites and sexual transmission of Zika.
Is Zika a mosquito?
A: Local mosquito-borne spread of Zika has been previously reported in the continental United States. In 2018 and 2019, no local mosquito-borne Zika virus transmission has been reported in the continental United States.
Why is chikungunya considered unimportant?
As with Zika, chikungunya was long considered unimportant because of its limited geographic distribution.
How to avoid mosquito bites?
In the meantime, people in affected areas, including travellers, should take care to avoid mosquito bites by wearing long clothing and using repellents, bed nets and window screens.
Does Zika cause brain damage?
That has all changed with the recent “ explosive ” spread of Zika in the Americas and the potential link with microcephaly (reduced head size and brain damage) in babies of pregnant women who were infected.
