, mainly Aedes aegypti in tropical regions. Aedes mosquitoes usually bite during the day, peaking during early morning and late afternoon/evening.
What type of virus is Zika virus?

single-stranded RNA virus of the Flaviviridae family
, genus Flavivirus.
What is Zika virus PDF?

How is Zika virus most commonly transmitted?
Zika virus is transmitted to people primarily
through the bite of an infected Aedes species mosquito
(Ae. aegypti and Ae. albopictus). These are the same mosquitoes that spread dengue and chikungunya viruses.
How does the Zika virus enter the body?
The Zika virus is most often spread to a person
through the bite of an infected mosquito
. If a mosquito bites a person who is already infected with the Zika virus, the virus infects the mosquito. Then, when the infected mosquito bites another person, the virus enters that person’s bloodstream and causes an infection.
Is Zika virus curable?
There is no
cure
, specific treatment or vaccine for
Zika virus
. Recently there has been spread of the
virus
to a number of countries not previously affected.
How long does Zika stay in sperm?
“We found that half of participants had detectable Zika virus particles in their blood at 15 days and in their urine at 11 days. Duration was the longest in semen. In a few men, parts of the virus were detected in semen for
as long as 4 months
.
Where did Ebola come from?
Ebola virus disease ( EVD ) is a severe disease caused by Ebola virus, a member of the filovirus family, which occurs in humans and other primates. The disease emerged in 1976 in almost simultaneous
outbreaks in the Democratic Republic of the Congo ( DRC ) and Sudan (now South Sudan)
.
Can you get Zika if you are already pregnant?
Zika virus can be passed from a pregnant woman to her fetus
. Zika primarily spreads through infected mosquitoes. You can also get Zika through sex without a condom with someone infected by Zika, even if that person does not show symptoms of Zika. There is no vaccine to prevent or medicine to treat Zika.
How do you protect yourself from Zika?

combination of tiny red bumps and reddish blotches
.
Does the Zika virus have cells?
The genetic material of Zika virus is made of ribonucleic acid (RNA). When the Zika virus infects cells, pieces of the virus RNA, known as subgenomic flavivirus RNAs (or sfRNAs for short),
accumulate in the cell
. Cells infected with dengue virus, which is closely related to the Zika virus, also accumulate sfRNA.
How long is Zika in your system?
Yes. There are both serum and urine tests for Zika. Urine is typically positive for
up to 14 days after symptom onset
, while the virus can be detected in the serum beyond that time. Check with your local health department or the CDC for more up-to-date information.
