State’s commitment to fighting rat lungworm questioned

KAILUA-KONA — Hawaii Island Rep. Richard Creagan and the Hawaii County Council don’t think the state Department of Health is as serious as it should be about rat lungworm disease.

The Health and Human Services Committee’s deferral of House Bill 2663 on Thursday morning only solidified that position.


The measure, introduced by Creagan, D-Naalehu, Ocean View, Captain Cook, Kealakekua, Kailua-Kona, doesn’t speak to rat lungworm directly. Instead, it would require each county’s district health officer to be a trained physician, which Creagan said would bring more expert attention to serious issues such as permanent disabilities caused by the disease now afflicting several Big Island residents.

District health officers on Kauai and Maui are trained physicians. Hawaii Island’s DHO, Aaron Ueno, is not.

A County Council resolution introduced by Puna Councilwoman Eileen O’Hara supporting Creagan’s bill passed committee unanimously on Wednesday. O’Hara also submitted written testimony to the HHS Committee in favor of the measure.

Creagan contends the lack of a trained physician as a district health officer has hampered response to disease outbreaks on Hawaii Island, such as the dengue fever outbreak of 2015-16 and several cases of rat lungworm last year. He asserted in his bill that Maui has handled similar problems more competently under the guidance of its DHO, Lorrin Pang, M.D.

“If you have somebody with boots on the ground in Hilo who is a physician, they can push the Health Department on behalf of the community,” Creagan said. “They’re going to stand up for the Big Island against the Health Department.”

Creagan went on to describe DOH as “dysfunctional,” particularly in regard to disease outbreaks. He cited state auditor report 17-14, which offered a highly critical review of DOH and its Disease Outbreak Control Division’s responses to recent disease outbreaks in Hawaii, including the recent dengue epidemic on the Big Island.

The report states DOH and its outbreak division suffered communication breakdowns, failed to establish proper guidance for other agency officials and didn’t conduct proper reviews after outbreaks concluded, among other criticisms.

Creagan said a knowledgeable physician serving Hawaii Island as DHO would bolster responses, but added State Epidemiologist Dr. Sarah Park, who heads the DOCD, is averse to any neighbor island opposition.

“Sarah Park says ‘Oh, (rat lungworm) is a lifestyle disease over there,” Creagan said. “She’s blaming the victim. So we need someone on the ground there.”

The Health Department offered testimony opposing Creagan’s bill, asserting the scope of a DHO’s job encompasses issues of public health, environmental health and behavioral health beyond a physician’s expertise.

Park took exception to Creagan’s characterization of her response to incidences of rat lungworm in Puna as “blaming the victim,” saying assigning blame isn’t what epidemiologists do.

She added, however, that looking at what people eat and drink and where they procure that sustenance is pertinent to the spread and containment of rat lungworm disease.

Park also said while a trained clinician serving as Hawaii Island’s DHO might offer a benefit in the form of a different perspective on a case-by-case basis, it wouldn’t meaningfully improve disease outbreak response.

“In public health, we do not provide health care,” Park said. “So to assume that a clinician in public health would then somehow effect a change in terms of making certain we have a better response, I don’t think that’s necessarily the case.”

DOH also noted in its testimony that recruiting a physician to the position of DHO is difficult because clinicians can make more money in the private sector.

While HB 2663 has been deferred, Creagan said he is in talks with HHS Committee Chairman John Mizuno about progressing the DHO requirement via a different legislative vehicle.

A second bill introduced by Creagan that gets at the rat lungworm problem in a roundabout way is House Bill 2498, which would fund a veterinary medical officer position within DOH on a permanent basis.

The position would focus on zoonotic diseases such as rat lungworm, which can pass between animals and people.

The measure, which also was heard by the HHS Committee on Thursday, passed with amendments despite DOH opposition.

DOH acknowledged in its testimony that bringing the position back would be helpful, but also noted that other members of the department, namely Park, have absorbed the relevant responsibilities and work in conjunction when necessary with the Department of Agriculture and the Hawaii State Veterinarian.

Creagan said rat lungworm is spreading beyond humans to other dead-end mammalian hosts, rendering the proposed position more crucial.

“Informally talking to people, we can confirm that there have been cases in dogs, cats and horses,” Creagan said.

State Sen. Russell Ruderman, D-Puna, Ka‘u, said he’s been trying for three years to secure funding for research at the rat lungworm lab within the Daniel K. Inouye College of Pharmacy at the University of Hawaii at Hilo.

The $1 million set for that research, appropriated in 2017 and which was to be distributed evenly over two years, was diverted away from research purposes at the lab and sent instead to DOH for education and vector control — money the department did not request.

The last-minute diversion was due to unrelated political infighting in the Legislature last year, Ruderman said, leaving the lack of research as collateral damage.

Puna Councilwoman Jen Ruggles said such research would include identification of safe catchment filters and the development of anti-parasitic drugs.

Because there’s been no money for research, she added, the County Council has been forced to scrape together contingency funds to share the cost of a preliminary study.


“I wish the DOH would take the rat lungworm disease more seriously,” she said.
