The 2016 National Health Security Preparedness Index shows gaps in health readiness among states.

Summer is rapidly approaching, and so is ideal mosquito weather and the opportunity for the spread of Zika — something hospitals need to be ready for.

The 2016 National Health Security Preparedness Index, released by the Robert Wood Johnson Foundation, shows that the United States scores 6.7 out of 10 for preparedness against public health emergencies, a 3.6 percent increase since the survey began three years ago. But, some of the regions most susceptible to the spread of Zika scored below the national level, including the Deep South.

Having many states improve their scores is a positive sign that the nation is improving, but there is concern that the South isn’t as prepared for the approaching mosquito season, says Glen Mays, professor of health policy at the University of Kentucky's College of Public Health, who leads the team overseeing the Index.

Presence of Wolbachia bacterium in the insects seen limiting their ability to transmit the rapidly spreading virus

Introducing a common bacterium into a species of mosquitoes drastically limits the insects’ ability to transmit the dangerous Zika virus that has been spreading rapidly, according to researchers at Brazil’s leading medical-research institute.

In a new study published on Wednesday in the journal Cell Host & Microbe, researchers at the Oswaldo Cruz Foundation (Fiocruz), in Rio de Janeiro, said their experiments have shown that injecting Aedes aegypti mosquito eggs with the Wolbachia bacterium makes the eventual adult mosquitoes highly resistant to the Zika virus, thereby limiting their ability to spread it.

The first case of locally acquired Zika in the continental United States has occurred through sexual transmission in Texas, the Centers for Disease Control and Prevention said Tuesday.

The case, announced by Dallas County health officials, involved a patient who had sex with someone who had recently returned from Venezuela infected with the mosquito-borne virus.

In a statement to CNN, the CDC said it confirmed the test results showing Zika present in the blood of a "nontraveler in the continental United States." They stressed that there was no risk to a developing fetus in this instance.

Based on that, the CDC says it will soon provide guidance on sexual transmission, with a "focus on the male sexual partners of women who are or who may be pregnant."

A Houston-area woman who traveled in November to El Salvador has been diagnosed with the Zika virus, public health officials said, raising concern that the mosquito-borne illness linked to a health crisis in Brazil could spread through the Americas. . . .

. . . The Texas case shows how the Zika virus is spreading after sparking an epidemic in Brazil that has led to an estimated 500,000 to 1.5 million cases, public health officials say.

Health officials in Brazil believe the virus is behind thousands of cases of microcephaly in that country—a condition in which infants are born with undersized brains and skulls—though it hasn’t before been linked to that rare condition. . . .

. . . U.S. officials say they are preparing for a possible influx of Zika this spring and summer, when populations of the mosquitoes that transmit it—Aedes aegypti and Aedes albopictus—flourish. . . .

. . . The department is also urging people to protect themselves from mosquitoes.
