The more researchers learn about the Zika virus, the scarier it appears, In USA federal health officials say, as they urge more money for mosquito control and development of vaccines and treatments. Scientists increasingly believe the Zika virus sweeping through Latin America and the Caribbean causes devastating defects in fetal brains if women become infected during pregnancy

• Researchers also have linked Zika to stillbirths, miscarriages, eye problems and other complications, with problems not only in the first trimester but throughout pregnancy.
• Brazilian researchers reported on April 10 2016  that Zika preferentially targets developing brain cells. They used stem cells to study embryonic brain development in lab dish, and reported in the journal Science that virus taken from a Brazilian patient destroyed the growing neural cells in a few days.
• There’s also evidence that some adults occasionally may suffer serious effects from Zika. Researchers already were studying whether Guillain-Barre syndrome, a nerve condition that can cause paralysis, is linked to Zika. And Sunday, another Brazilian research team reported two Zika patients who suffered yet another problem, a brain inflammation that damages the coating of nerve cells in a way similar to multiple sclerosis.
• The CDC has warned women who are pregnant or attempting to conceive to avoid travel to Zika-affected areas. Because Zika sometimes spreads through sexual intercourse, the CDC also says men who’ve travelled to Zika-affected areas either should use condoms with their pregnant partners or avoid sex until the baby’s born.
  More than 300 travel-associated cases of Zika have been reported in the U.S. so far( April 14 2016), and the CDC also wants travelers to take extra steps to avoid being bitten by mosquitoes when they come home — so local insects won’t pick up the virus and spread it. While CDC does expect some clusters of homegrown Zika to occur, it is working with state and local governments to boost mosquito control.
   

About 1 in 5 people infected with Zika virus become ill

What is Zika Virus disease (Zika)?

Zika is a disease caused by Zika virus that is spread to people primarily through the bite of an infected Aedes species mosquito. The most common symptoms of Zika are fever, rash, joint pain, and conjunctivitis (red eyes). The illness is usually mild with symptoms lasting for several days to a week.

Symptoms

• About 1 in 5 people infected with Zika virus become ill (i.e., develop Zika).
• The most common symptoms of Zika are fever, rash, joint pain, or conjunctivitis (red eyes). Other common symptoms include muscle pain and headache. The incubation period (the time from exposure to symptoms) for Zika virus disease is not known, but is likely to be a few days to a week.
• The illness is usually mild with symptoms lasting for several days to a week.
• Zika virus usually remains in the blood of an infected person for a few days but it can be found longer in some people.
• Severe disease requiring hospitalization is uncommon.
• Deaths are rare.

Diagnosis

• The symptoms of Zika are similar to those of dengue and chikungunya, diseases spread through the same mosquitoes that transmit Zika.
• See your healthcare provider if you develop the symptoms described above and have visited an area where Zika is found.
• If you have recently traveled, tell your healthcare provider when and where you traveled.
• Your healthcare provider may order blood tests to look for Zika or other similar viruses like dengue or chikungunya.

Treatment

• No vaccine or medications are available to prevent or treat Zika infections.
• Treat the symptoms:
  • Get plenty of rest
  • Drink fluids to prevent dehydration
  • Take medicines, such as acetaminophen or paracetamol, to relieve fever and pain
  • Do not take aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs), like ibuprofen and naproxen. Aspirin and NSAIDs should be avoided until dengue can be ruled out to reduce the risk of hemorrhage (bleeding). If you are taking medicine for another medical condition, talk to your healthcare provider before taking additional medication.
• If you have Zika, avoid mosquito bites for the first week of your illness.
  • During the first week of infection, Zika virus can be found in the blood and passed from an infected person to another mosquito through mosquito bites.
  • An infected mosquito can then spread the virus to other people.
