MICHAEL SMITH: Mosquitoes
in tropical areas
are causing an outbreak
of a frightening disease called
the Zika virus.
Now, we've never given
this virus much attention
before, since Zika will only
give you mild symptoms,
like a fever, rash,
and headaches.
In fact, most people won't even
know they have it.
But it's a different story
if you're pregnant or planning
to become pregnant.
The virus may cause
a serious birth defect called
microcephaly, where a baby's
head and brain are much smaller
than normal.
It can be fatal or cause
severe developmental problems.
Now right now, the danger
is when you travel.
Most experts don't expect Zika
to become widespread in the US.
But women who are pregnant
or trying should not travel
to Central America, South
America, and the Caribbean,
where the virus is spreading.
That includes big vacation
spots, like Mexico, Puerto Rico,
and the US Virgin Islands.
Some countries have even told
citizens to not get pregnant
until the outbreak is
under control.
If you have to go, use bug spray
and reapply it
throughout the day
and wear long sleeve shirts
and pants.
Now do this both indoors
and outdoors.
If a mosquito bites you,
the virus can be transmitted
to others.
So protect yourself when you
come back from your trip, too.
If you do get symptoms,
be sure to see your doctor,
especially if you're pregnant.
If you're expecting
and you've already been to one
of those areas,
also tell your doctor,
so she can check on your baby.
