Thousands of infants in Brazil are being diagnosed with a devastating birth defect
-
and medical researchers believe it might be linked to a mosquito borne virus.
-
So, what is this mysterious virus and how do we stop it?
-
Zika, a strange mosquito borne virus, is sweeping through many Central and South American countries.
-
Current estimates place the number of Zika cases at over a million in Brazil alone.
-
And in response to the outbreak the CDC has implemented two new travel bans, to an already large list,
-
for pregnant women, one on the United States Virgin Islands
-
and the other on the Dominican Republic.
-
The ban is for pregnant women specifically because since the epidemic started,
-
the incidences of microcephaly, a devastating birth defect, have skyrocketed.
-
Microcephaly is a condition where a baby is born with a small head. Because the head is so small in those born with the condition,
-
the brain is small too, meaning it’s underdeveloped. Which can cause a whole
-
range of other health issues like cognitive deficits, seizures, feeding problems, vision problems and hearing loss.
-
Unfortunately there’s no cure for the condition,
-
only treatments for its effects.
-
Microcephaly is typically seen in rates of about 2 in 10,000 births according to a study
-
published in the journal Birth Defects Research (Part A). But nearly 4,000 cases have been
-
reported in Brazil since October, that’s nearly 26 times the normal rate. And researchers
-
strongly suspect that the birth defect is linked to the Zika virus.
-
Now this epidemic seemed to have come out of nowhere. The mosquito that carries the virus,
-
was pretty much eradicated in Brazil in the 1950s.
-
But as the decades wore on, it made its way back.
-
Then last year reports of Zika in Brazil started popping up.
-
It wasn’t taken too seriously, since its symptoms in adult are mild, just things like a fever or a rash.
-
It wasn’t until the rate of Microcephaly shot up that the world started to take notice.
-
Now the battle against Zika is underway, and one that Brazil is badly losing, according to the health minister.
-
And it is literally a battle, 220,000 members of the armed forces are going door to door to help in the current mosquito eradication efforts.
-
But it’s not just Brazil, Zika has been reported in 24 regions around the world
-
mostly in tropical areas.
-
Each country is issuing warnings, some seem extreme.
-
For instance, the government of El Salvador told women to avoid pregnancy for two years!
-
As for the zika virus itself, there’s no treatment, vaccine, or cure.
-
The CDC says the best way to avoid the virus, is to avoid mosquito bites.
-
Now, experts say that a US outbreak is unlikely to occur.
-
They believe that most cases will happen to those who travel to Brazil and other affected countries. But this summer tons of
-
But this summer tons of people will descend on Rio de Janeiro for the 2016 Games.
-
Which some experts are calling “a perfect dissemination vehicle for Zika.”
-
If people travel to Brazil, get zika from a mosquito bite,
-
then return home and get bitten there, the zika virus could transfer to the local mosquito population.
-
Which would mean that there is the potential for localized outbreaks in other parts of the world.
-
Zika is just one of the many viruses and diseases that mosquitos carry.

-
Most mosquitos actually fight malaria with their immune responses to parasites.
-
After mosquitos sucks up its bloody meal, a peritrophic matrix or barrier forms inbetween the bugs lining of their midgate and their blood.
