At the U.S.’s doorstep, one quarter of the territory’s population could be infected by year’s end, giving health authorities a rare chance to study the virus
“In ultrasounds he gives pregnant women who are infected with the virus in this American territory, he has seen a 22-week-old fetus with serious brain damage and two others with stunted growth. He is bracing for more.
“’If you ask me in a month,” says Dr. de la Vega, an obstetrician-gynecologist and chief of a high-risk-pregnancy unit at the capital’s University Hospital, ‘we may have 10 times the detection rate.’
“Zika has blanketed three-quarters of this lush island over the past six months, say health authorities, who expect it to keep spreading now that it is prime mosquito season. More than 1,350 people have tested positive for Zika since the beginning of the epidemic here, including 168 pregnant women. One patient died. Thousands more are likely infected without symptoms, health authorities say.
Puerto Rico’s battle with Zika is giving local and U.S. health authorities a rare chance to better understand the disease as it makes its relentless march across the Americas.
“The island has advantages over Latin American and Caribbean nations that lack its modern medical system. It has strong public-health surveillance and anticipated Zika’s arrival, unlike Brazil, where the virus spread unnoticed for months.
“’This is the best shot we have at understanding the natural spectrum of the disease,’ says Johnny Rullán, former secretary of health and former state epidemiologist for the territory.
Puerto Rico has been hit harder than any mainland U.S. state is likely to be, U.S. health authorities say. The Aedes aegypti mosquito that spreads Zika teems here, flourishing in the steamy climate and dense neighborhoods. It invades the many homes lacking screens and air conditioning. It incubates in unsealed septic tanks, old tires and other places where stagnant water stands.
