Flesh-eating bacteria, cancer-causing chemicals, and mold: Harvey and Irma's lingering health threats

In the weeks following Hurricane Irma, parts of Florida have been awash in millions of gallons of sewage. Meanwhile, in Texas, oil refineries and chemical plants have dumped a year’s worth of cancer-causing pollutants into the air following Hurricane Harvey. In both states, doctors are on the lookout for an uptick in respiratory problems, skin infections, and mosquito-borne diseases brought on by the water and mold the storms left behind.
Thanks in part to better emergency planning and response, the immediate death tolls from Harvey and Irma seem to be far lower than those of Hurricanes Katrina and Sandy, which took some
1,400 and
117 lives in the US respectively. So far, a total of 80 deaths have been reported in
Texas after Harvey, and there have been at least 42 deaths in
Florida as a result of Irma.
But health officials are warning about the much longer-term health fallout from this year’s hurricane season. America’s Gulf Coast region perennially records some of the worst health outcomes in the US — and they’ll almost surely be aggravated by the storms that recently slammed the southern states. (That’s not to mention the hurricanes’ hefty price tag, which
could total nearly $200 billion.)
Here are some of the most severe and worrying health problems that may linger in the southern US, long after the 2017 hurricane season.
1) A bacteria could cause an uptick in skin infections and deaths

Vibrio vulnificus is a bacterium that lives in the Gulf Coast waters and kills one in seven people it infects. It’s also one of several pathogens that can lead to necrotizing fasciitis, which is commonly referred to as “flesh-eating disease.”
With
the flooding from the hurricanes and storm surges, people have been coming into contact with coastal water, and potentially with Vibrio.
“We’re on the lookout for that here [in Texas],” said Peter Hotez, dean of the National School of Tropical Medicine and a professor of pediatrics and molecular virology and microbiology at Baylor College of Medicine.
Health officials in Texas have already announced the death of a
77-year-old Harris countyresident from Vibrio: She came into contact with flood waters when they ripped into her home, and later died as a result of flesh-eating disease. According to
Florida Department of Health, as of October 13, 41 cases of vibrio have been reported this year
across 20 counties.
The toll may continue to grow. There was an uptick of Vibrio infections across the
Southern US following Katrina, including five deadly cases — and Hotez said health officials expect we’ll see much the same following Harvey.
Though infections are rare, Vibrio can sicken people — especially those with weakened immune systems or other chronic health issues — in two disturbing ways: 1) through wound infections, which sometimes require amputation to get rid of; 2) and through septicemia, an infection of the bloodstream. “We’ll be watching for skin infections from people who have had direct contact with floodwaters,” Hotez added, “especially if they’ve had open wounds.”
2) Parts of the Texas Gulf Coast have been bathed in cancer-causing pollutants

The hurricanes that hit the US also unleashed a cloud of pollutants that pose health dangers — in both the short and long term.
The Texas Gulf Coast is home to many of the nation’s oil refineries and chemical plants, which routinely use chemicals like benzene that are known carcinogens. Harvey flooded or damaged more than
50 oil refineries and chemical plants, dumping a
year’s worth of pollutants into Texas within a matter of weeks.
According to the
Austin American-Statesman, “Fifty-five refineries and petrochemical plants in the Houston, Corpus Christi and Beaumont areas collectively emitted 5.8 million pounds of benzene, ammonia and other pollutants to the air in connection with Hurricane Harvey.” Independent
environmental advocacy groups have already been warning that benzene levels in some areas of Texas have reached worrying highs, while more than a
dozen toxic waste sites were also flooded or destroyed.
“Whether there’s going to be an uptick in cancer rates is something we’re going to have to follow,” said Hotez.
3) Irma caused more than 28 million gallons of sewage to be dumped across Florida

South Florida is not the petrochemical capital Texas is. But many of its septic tanks, wastewater treatment plants, and agricultural and industrial areas were flooded or shut off because of Irma, releasing raw sewage and waste across the state in what’s been described as
“a literal shytstorm.”
Florida relies on a system of
wastewater lift stations with electronic pumps that move sewage through the state. But when Irma knocked out the electricity in many areas, some of the sewage pumps were also cut off, leading to overflows and spills of raw sewage — which harbor dangerous bacteria, viruses, and parasites, such as E. coli, salmonella, and hepatitis A.
There have already been dozens of Irma-related pollution notices describing the streets, homes, and neighborhoods that have been drenched with wastewater. Emily Atkin at the
New Republic tallied up the total damage in these filings — and it’s staggering:
Combined, those discharge reports showed more than 28 million gallons of treated and untreated sewage released in 22 counties. The total amount is surely much more; at least 43 of those reports listed either an “unknown” or “ongoing” amount of waste released, and new reports continue to roll in — sometimes as many as a dozen per hour.
That’s why the Florida
Department of Health is warning locals to take precautions and avoid the polluted water Irma left behind.
