People do not become contagious, so they cannot transmit the infection to someone else.Īlthough the CDC is monitoring the situation in Hawaii, it cannot comment on the investigation, said Amy Rowland, a spokeswoman for the agency’s Center for Global Health. However, an infection can incubate in only a single day or in six weeks. The illness usually lasts between two weeks and two months, and on average, the incubation period is one to three weeks. Children will also run fevers and feel abdominal pain more than adults. “In children, it’s more the nausea and vomiting, not so much the headache,” she said. She added that adults commonly report neck stiffness, nausea and vomiting. So usually, in adults, one of the main things that you hear complaint of is a headache,” Walden said. “Angiostrongylus cantonensis can present differently in adults and children. There may also be very rare cases of contamination through water. Transmission can also occur when people eat infected crabs, shrimp and frogs, though this is believed to be less common, Walden said. For example, poorly washed lettuce or other raw produce may contain an unnoticed snail or slug. Most cases result from consuming, either accidentally or on purpose, raw or undercooked snails and slugs that are infected with the parasite. Heather Stockdale Walden, an assistant professor in the department of infectious diseases and pathology at the University of Florida, said rat lungworm disease has “been endemic in Hawaii for at least 50 years, so it’s been there for a while.” The state cannot confirm how each person became infected, “but we do know that people can acquire the parasite by consuming raw or undercooked snails and slugs,” she said. “The investigation is fluid and the cluster of cases, though not all confirmed, are very concerning,” Okubo wrote in an email. Typically, the state gets reports of one to nine cases of rat lungworm each year, with two related deaths since 2007, Okubo said. The confirmed cases on Maui involve four residents and two visitors, and the confirmed cases on Hawaii involve residents only. Three possible cases on Maui are also under investigation along with one suspected case on Hawaii, said Janice Okubo, a spokeswoman for the Department of Health. Rat lungworm disease, a parasite officially known as Angiostrongylus cantonensis, affects the brain and the spinal cord, according to the Centers for Disease Control and Prevention. The Hawaii State Department of Health has confirmed six cases of rat lungworm disease on the island of Maui and three cases on the Big Island over the past three months, an official said Monday. Manilla said he’s had “several operations, two pneumonias, a blood clot … (and) a kidney issue, all of which was spurred by the rat lung.” Manilla, a teacher at University of California at Berkley’s Graduate School of Journalism, told KGMB the parasite landed him in the intensive care unit for two months. Lape told the station she felt something was wrong before they even left Hawaii, likening the symptoms to “somebody taking a hot knife and just stabbing me in different parts of my body.” HAWAII – A California couple’s honeymoon to Hawaii left them in agony after both newlyweds contracted rat lungworm disease, according to KGMB-TV.īen Manilla, 64, and Eliza Lape, 57, got married on Maui in January, then spent two weeks in the island’s remote Hana area for their honeymoon.
