How does the Zika virus work?
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.
How does Zika cause death?
-In severe cases, zika virus can lead to fatal brain damage in babies and can also result in miscarriage or stillbirth in pregnant women. -There is enough evidence to show that Zika virus can cause infections during pregnancy, genetic problems and exposure to toxic substances.
What is the Zika virus summary?
Zika virus disease is caused by a virus transmitted primarily by Aedes mosquitoes, which bite during the day. Symptoms are generally mild and include fever, rash, conjunctivitis, muscle and joint pain, malaise or headache. Symptoms typically last for 2–7 days.
