Puerto Rico Braces for Its Own Zika Epidemic - NYT


Puerto Rico Braces for Its Own Zika Epidemic

The governor’s office recently announced detailed plans to attack mosquito hot spots: cemeteries, abandoned houses, auto junkyards, unsealed septic tanks and piles of old tires.
Each of the island’s 78 municipalities has until April 1 “to clean up their acts,” Dr. Rullán said.
As of Friday, 900,000 of an estimated one million discarded tires had been picked up and moved to depots far from residential areas.
Much of the work was done by convicted drug abusers living in a network of halfway houses who can earn early release through public service, he said.
Many of the island’s hundreds of schools have no screens or air-conditioning. Since high school girls account for about 20 percent of all pregnancies here, officials plan to screen the windows to keep out mosquitoes.
That alone is a big job. “That means measuring each window,” Dr. Rullán said. “And what are you going to do about doors if you have 50 kids running in and out?”
As a first step, the public school dress code has been changed so girls can wear pants, and teachers are supposed to give mosquito repellent to all girls.
Here is a look at the most prominent rumors and theories about Zika virus, along with responses from scientists.
In the island’s 109 cemeteries and its many auto junkyards and public dumps, mosquito-control teams have begun spraying pesticides that kill the insect’s larvae. But the work is never-ending because rain washes it away.
Moreover, the island is dotted with hundreds of abandoned homes with water-collecting birdbaths and pools. Puerto Rico has 500,000 septic tanks, each of which can produce up to 1,500 mosquitoes a day if left unsealed.
Teams cannot enter an abandoned property or screen a septic tank when the owner is absent, “so we’re asking for a new law letting us enter,” Dr. Rullán said.
The ideal, he said, would be to spray every property within 150 yards — the distance a mosquito normally travels — of every pregnant woman’s home.
The island’s birthrate is about 10 per 1,000 women, and nearly 100 women a day become pregnant here. Just finding them all would be a gargantuan task.
A Hunt for Solutions
Other mosquito-control efforts are even less effective.
Highly visible fogging by trucks is what most people associate with government mosquito-fighting. Butpermethrin, the insecticidal fogger used for years, may actually be useless.
Tests at several sites have found that its ability to kill mosquitoes has significantly faded, so the island will have to choose a new pesticide and retrain workers to use it.
Even with the right chemical, the impact of fogging is dubious. Aedes mosquitoes typically hatch in gardens and slip into houses to hide in closets and under beds. When the spray trucks go by, many people close their windows, locking themselves in with the enemy.
Aedes mosquitoes are “sip feeders” and bite several times for each blood meal. The number required to make it likely that just one member of the household is infected is as few as three mosquitoes, experts have found.
Moreover, by a “very inconvenient coincidence,” the Environmental Protection Agency has effectively banned the chemical used here to kill juvenile mosquitoes, Audrey Lenhart, a C.D.C. entomologist, noted. The chemical, temephos, has been in use since 1965 and definitely works, she said. But it is not very profitable, so when the agency demanded safety data costing about $3 million to gather, the manufacturers decided instead to quit making it.
Puerto Rico still has a nine-month supply, Dr. Lenhart said, and the E.P.A. may issue an emergency use permit for more.
Mosquitoes are not the only mode of Zika transmission, however. Health authorities here have also been forced to grapple with an unexpected twist: the discovery that sex spreads the virus.
The government has frozen the price of condoms, threatening stores with fines of up to $10,000 if they raise them. (It did the same for repellent and window screens.)
At nutrition clinics, teachers like Ms. Morales have struggled to explain, as they hand out condoms, why the partners even of pregnant women should wear them.
In a radio interview in January, Puerto Rico’s health secretary, Dr. Ana Ríus, advised women to delay pregnancy altogether, if possible, until the epidemic is over.
But local radio commentators accused her of alarmism, and Roberto González, archbishop of the Catholic Church, publicly criticized the government’s condom distribution plans. Instead, he counseled people to “practice self-discipline, which we believe is the only rational attitude and faith.”
It will be many months before officials know whether their efforts have slowed the lightning advance of the Zika virus.
“Come October, when the babies start being born,” Dr. Rullán said, “I’ll know if we acted in time or not.”

HAVANA The Rolling Stones were meant to play a rock 'n' roll show in Havana on Sunday but were delayed five days because of the inconvenient arrival of another foreign visitor: U.S. President Barack Obama.
Obama lands on Sunday for a 48-hour visit 15 months after he reversed more than half a century of U.S. policy on Cuba and started normalizing relations with the former Cold War adversary.
The Stones' Latin American tour happened to roughly coincide and the band was at first set to play Havana on Sunday, but organizers then learned of the Obama trip and postponed the show until Friday, the band's production manager said.
"At one point we thought he (Obama) was coming to the show," Dale "Opie" Skjerseth told reporters on Saturday from the outdoor sports complex where the Stones will play.
"He's our opening act," Skjerseth joked.
The Stones added the free show to the end of a Latin American tour, becoming the first major international rock stars to play Cuba.
"They like to be the first of everything," Skjerseth said.
He said the band members were also aware their music and that of the Beatles and Elvis Presely were once banned by the Communist government as "ideological deviation."
"They figured they'd like to come here and give it (rock) to them," Skjerseth said.
Havana is preparing for Obama with an extraordinary street-paving campaign and restricting areas he will visit for security reasons. At the same time, the groundwork for the Stones production has also been impressive if not unprecedented for Cuba.
The band brought in 61 shipping containers with an estimated 500 tonnes of equipment such as the stage, speakers, lights and video screens, Skjerseth said. A Boeing 747 arrived on Friday from Mexico carrying the last of the equipment, he said.
A crew of 140 Stones employees and at least 80 Cubans have set up on grounds including a football field and adjoining baseball fields with room for hundreds of thousands of spectators, who are invited to arrive for free on a first-come, first-served basis.
