Over 150 pregnant women in the United States appear to have been infected with Zika virus. That's in addition to more than 120 women affected by Zika in U.S. territories, mainly Puerto Rico.

Those are the latest figures from the Centers for Disease Control and Prevention in Atlanta, which has been keeping track of all pregnant women in the U.S. and its territories who have lab tests suggestive of Zika virus infections.

While Congress fidgets over whether and how to pay for the fight against the Zika virus, state and local health departments are scrambling and slimming down.

That's because these front-line public health agencies have already seen their budgets chopped because of the debate.

Amir Attaran, a professor in the School of Public Health and the School of Law at the University of Ottawa, isn't afraid to take a bold stand.

He has written a commentary for the Harvard Public Health Review, published this week, with the headline, "Why Public Health Concerns for Global Spread of Zika Virus Means that Rio de Janeiro's 2016 Olympic Games Must Not Proceed."

Though it's the world's top infectious killer, tuberculosis is surprisingly tricky to diagnose. Scientists think that video gamers can help them create a better diagnostic test.

An online puzzle released Monday will see whether the researchers are right. Players of a Web-based game called EteRNA will try to design a sensor molecule that could potentially make diagnosing TB as easy as taking a home pregnancy test. The TB puzzle marks the launch of "EteRNA Medicine."

As summer approaches, anxiety about Zika is growing in Gulf Coast states like Florida and Texas. The virus hasn't spread to mosquitoes in the region, and it may not, but experts are preparing nonetheless.

Zika's arrival in the U.S. this summer seems almost inevitable, health officials keep saying.

The virus has already touched down in northern Mexico and Puerto Rico. And just this week, the Centers for Disease Control and Prevention said the number of states with virus-carrying mosquitoes was larger than previously thought.

So the looming question is: Once Zika is here, how big will the outbreak be?

Could swallowing the eggs of a parasitic worm help treat a disease?

It might just work in some cases, according to the work of P'ng Loke and Ken Cadwell, two researchers at New York University who study parasites and the immune system.

White House Says It Will Cut Ebola Funding To Address Zika

Apr 6, 2016

Top officials with the Obama administration said Wednesday that they'll redirect $589 million toward the Zika virus response. Most of that money was to be used to deal with Ebola virus.

Almost two months ago, the Obama administration requested $1.9 billion from Congress to respond to the Zika threat.

"But Congress has yet to act," Shaun Donovan, director of the Office of Management and Budget, said in a news conference. "In the absence of congressional action, we must scale up Zika preparedness and response activities right now."

The emergence of nine cases of a fungal infection known as Valley Fever in southeast Washington over the last five years has state and federal health officials concerned. This week, the state and the CDC are launching a $50,000 study.

The Zika virus was likely spreading in South America — silently — long before health officials detected it, scientists reported Thursday.

The findings, published in the journal Science, suggest an air traveler brought the virus to the Americas sometime between May and December of 2013, or more than a year before Brazil reported the first cases of Zika in early 2015.

There's something different about the way these babies cry.

That's a realization that hit me after spending day after day with babies in Brazil who were born to mothers who were infected with the Zika virus when they were pregnant.

It's not just that they cry more easily, and longer — which they do. There's also something strange — harsher and more pained — about the cries of many of these babies.

Researchers are working furiously to determine if the Zika virus now spreading in Latin America is responsible for a spike in cases in Guillain-Barre syndrome, a condition that can cause temporary paralysis.

Valentina Vitoria was born in December.

She has microcephaly, the birth defect that causes an abnormally small head and can cause brain damage as well.

The baby's mother is 32-year-old Fabiane Lopes. She's caring for her daughter in a tiny, windowless one-room apartment in Rio de Janeiro. A whirring fan is the only relief they have from the heat.

In Brazil, doctors are getting closer to untangling the possible connection of Zika to microcephaly. The country has seen thousands of babies born with this birth defect since the virus arrived last year.

You wouldn't think of calling a mosquito "man's best friend." But that's the nickname that biologist Denise Valle uses for Aedes aegypti, the species that's been spreading the Zika virus in Brazil and many other countries in Latin America.

I think "man's best enemy" might be better.

The thing is, this mosquito likes to live near humans.

For Carnival in Brazil, lots of women don giant feather headdresses and skimpy bikinis.

But for a pre-Carnival event, Elaine Cuoto is dressed as a mosquito — complete with a long proboscis and gossamer wings.

She is part of a group of health workers dancing by a metro station in a working-class neighborhood of Rio's north zone. A few others are wearing mosquito costumes as well. And they're singing a catchy tune:

"If Zika attacks, use this number to report it, 7-4-6. Pay attention!"
