HOUSTON --A global health conference in Houston this week addressed the growing threat of the Zika virus in the U.S. CBS News was there, and checked in with local troops trying to fight the virus.

A team of mosquito hunters has set traps throughout Houston neighborhoods.

They take them back to a lab, where they freeze the insects, sort them, and grind them up for testing. They look for viruses like West Nile, dengue, and now Zika.

"The one misconception that I'm hearing is that it's not really not going to be a problem," Dr. Persse said.

"But certainly for the families of the children who are born with microcephaly, it's going to be devastating."

The sentiment at the conference was that there simply are not enough resources in the U.S. to fight the Zika virus, which is especially troubling with mosquito season just around the corner.
