The number of documented cases of the Zika virus in the US continue to increase. Cases of the Zika virus have recently been documented in Delaware and Pennsylvania.
No locally transmitted cases have been reported in the US. Lucky for us it's winter making the transmission for the virus by mosquitoes less likely.
The CDC continues to advise pregnant women not to travel to countries where there are Zika virus outbreaks.
We all need to take note of the rapidity of transmission of this virus in South and Central America demonstrating that women's health including family planning and contraception are global issues. We should all be very concerned.
